Trauma-focused evidence-based psychotherapies (TF-EBPs), including cognitive processing therapy (CPT) and prolonged exposure therapy (PE), are recommended treatments for posttraumatic stress disorder (PTSD) in clinical practice guidelines.^1-3 To increase initiation of these treatments, the US Department of Veterans Affairs (VA) used a large-scale dissemination and implementation effort to improve access to TF-EBP.^4,5 These efforts achieved modest success, increasing prevalence of TF-EBP from a handful of veterans in 2004 to an annual prevalence of 14.6% for CPT and 4.3% for PE in 2014.⁶

Throughout these efforts, qualitative studies have been used to better understand veterans’ perspectives on receiving TF-EBP care.^7-18 Barriers to initiation of and engagement in TF-EBP and PTSD care have been identified from these qualitative studies. One identified barrier was lack of knowledge—particularly lack of knowledge about what is meant by a PTSD diagnosis and available treatments.^7-10 Stigma (ie, automatic negative associations) toward mental health problems or seeking mental health care also has been identified as a barrier to initiation.^7,10-14 Perceptions of poor alignment between treatment and veteran goals, including lack of buy-in for the rationale, served as barriers to initiation and engagement.^8,15-18

Using prior qualitative work, numerous initiatives have been developed to reduce stigma, facilitate conversations about how treatment aligns with goals, and fill knowledge gaps, particularly through online resources and shared decision-making.^19,20 To better inform the state of veterans’ experiences with TF-EBP, a qualitative investigation was conducted involving veterans who recently initiated TF-EBP. Themes directly related to transitions to TF-EBP were identified; however, all veterans interviewed also described their experiences with TFEBP engagement and mental health care. Consistent with recommendations for qualitative methods, this study extends prior work on transitions to TF-EBP by describing themes with a distinct focus on the experience of engaging with TF-EBP and mental health care.^21,22

Methods

The experiences of veterans who were transitioning into TF-EBPs were collected in semistructured interviews and analyzed. The semistructured interview guide was developed and refined in consultation with both qualitative methods experts and PTSD treatment experts to ensure that 6 content domains were appropriately queried: PTSD treatment options, cultural sensitivity of treatment, PTSD treatment selection, transition criteria, beliefs about stabilization treatment, and treatment needs/preferences.

Participants were identified using the VA Corporate Data Warehouse and included post-9/11 veterans who had recently initiated CPT or PE for the first time between September 1, 2021, and September 1, 2022. More details of participant selection are available in Holder et al.²¹ From a population of 10,814 patients, stratified random sampling generated a recruitment pool of 200 veterans for further outreach. The strata were defined such that this recruitment pool had similar proportions of demographic characteristics (ie, gender, race, ethnicity) to the population of eligible veterans, equivalent distributions of time to CPT or PE initiation (ie, 33.3% < 1 year, 33.3% 1-3 years, and 33.3% > 3 years), and adequate variability in TF-EBP type (ie, 66.7% CPT, 33.3% PE). A manual chart review in the recruitment pool excluded 12 veterans who did not initiate CPT or PE, 1 veteran with evidence of current active psychosis and/or cognitive impairment that would likely preclude comprehension of study materials, and 1 who was deceased.

Eligible veterans from the recruitment pool were contacted in groups of 25. First, a recruitment letter with study information and instructions to opt-out of further contact was mailed or emailed to veterans. After 2 weeks, veterans who had not responded were contacted by phone up to 3 times. Veterans interested in participating were scheduled for a 1-time visit that included verbal consent and the qualitative interview. Metrics were established a priori to ensure an adequately diverse and inclusive sample. Specifically, a minimum number of racial and/or ethnic minority veterans (33%) and women veterans (20%) were sought. Equal distribution across the 3 categories of time from first mental health visit to CPT/PE initiation also was targeted. Throughout enrollment, recruitment efforts were adapted to meet these metrics in the emerging sample. While the goal was to generate a diverse and inclusive sample using these methods, the sample was not intended to be representative of the population.

Of the 186 eligible participants, 21 declined participation and 26 could not be reached. The targeted sample was reached after exhausting contact for 47 veterans and contacting 80 veterans for a final response rate of 40% among fully contacted veterans and 27% among veterans with any contact. The final sample included 30 veterans who received CPT or PE in VA facilities (Table).

After veterans provided verbal consent for study participation, sociodemographic information was verbally reported, and a 30- to 60-minute semistructured qualitative phone interview was recorded and transcribed. Veterans received $40 for participation. All procedures were approved by the University of California San Francisco Institutional Review Board.

Qualitative Data Analysis

Rapid analysis procedures were used to analyze qualitative data. This approach is suitable for focused, moderately structured qualitative analyses in health services research and facilitates rapid dissemination to stakeholders.²³ The qualitative analysts were 2 clinical psychologists with expertise in PTSD treatment (NH primary and RR secondary). Consistent with rapid analysis procedures, analysts prepared a templated summary (including relevant quotations) of each interview, organized by the prespecified content domains. Interviews were summarized independently, compared to ensure consistency, and discrepancies were resolved through review of the interview source materials. Individual summary templates were combined into a master analytic matrix to facilitate the identification of patterns and delineation of themes. Analysts routinely met to identify, discuss, and refine preliminary themes, revisiting source materials to reach consensus as needed.

Results

Fifteen themes were identified and organized into 2 distinct focus areas: themes directly related to the transition to TF-EBP (8 themes) and themes related to veterans’ experiences with TF-EBP and general mental health care with potential process-improvement implications (7 themes).²¹ Seven themes were identified related to experiences with TF-EBP engagement and VA mental health care. The 7 themes related to TF-EBP engagement and VA mental health care themes are summarized with exemplary quotations.

Veterans want a better understanding of psychotherapy and engaging with VA mental health. Veterans reported that they generally had a poor or “nebulous” understanding about the experience of psychotherapy. For example, veterans exhibited confusion about whether certain experiences were equivalent to participating in psychotherapy. They were sometimes unable to distinguish between interactions such as assessment, disability evaluations, peer support, and psychotherapy. One veteran described a conversation with a TFEBP therapist about prior treatment:

She [asked], have you ever been, or gone through a therapy to begin with? And I, I said, well I just chatted with somebody. And she said that’s not, that’s not therapy. So, I was like, oh, it’s not? That’s not what people do?

Veterans were surprised the VA offered a diverse range of psychotherapy interventions, rather than simply therapy. They did not realize there were different types of psychotherapy. As a result, veterans were not aware that some VA mental practitioners have specialty training and certification to provide treatment matched to specific diagnoses or needs. They thought that all clinicians could provide the same care. One veteran described their understanding:

I just figured all mental health people are mental health people. I didn’t have a better understanding of the system and all the different levels and how it plays out and specialties and things like that. Which, I guess, I should have because you have a primary care doctor, but then you have specialists in all these other different sectors that specialize in one particular area. I guess that should’ve been common sense, but it wasn’t.

Stigma was a barrier to seeking and engaging in mental health care. Veterans discovered they had to overcome stigma associated with seeking and engaging in mental health treatment. Military culture was often discussed as promoting stigma regarding mental health treatment. Specifically, veterans described that seeking treatment meant “either, I’m weak or I’m gonna be seen as weak.” In active-duty settings, the strategy for dealing with mental health symptoms was to “leave those feelings, you push ‘em aside,” an approach highly inconsistent with TF-EBP. In some cases, incorrect information about the VA and PTSD was presented as part of discharge from the military, leading to long-term skepticism of the VA and PTSD treatment. One veteran described his experience as part of a class on the VA compensation and pension assessment process for service-connected disabilities during his military discharge:

[A fellow discharging soldier asked] what about like PTSD, gettin’ rated for PTSD. I hear they take our weapons and stuff like we can’t own firearms and all that stuff. And [the instructor] was like, well, yes that’s a thing. He didn’t explain it like if you get compensated for PTSD you don’t lose your rights to carry a firearm or to have, to be able to go hunting.

Importantly, veterans often described how other identities (eg, race, ethnicity, gender, region of origin) interacted with military culture to enhance stigma. Hearing messaging from multiple sources reinforced beliefs that mental health treatment is inappropriate or is associated with weakness:

As a first-generation Italian, I was always taught keep your feelings to yourself. Never talk outside your family. Never bring up problems to other people and stuff like that. Same with the military. And then the old stigma working in [emergency medical services] and public safety, you’re weak if you get help.

The fundamentals of therapy, including rapport and flexibility, were important. Veterans valued nonspecific therapy factors, genuine empathy, building trust, being honest about treatment, personality, and rapport. These characteristics were almost universally described as particularly important:

I liked the fact that she made it personable and she cared. It wasn’t just like, here, we’re gonna start this. She explained it in the ways I could understand, not in medical terms, so to speak, but that’s what I liked about her. She really cared about what she did and helping me.

Flexibility was viewed as an asset, particularly when clinicians acknowledged veteran autonomy. A consistent example was when veterans were able to titrate trauma disclosure. One veteran described this flexible treatment experience: “She was right there in the room, she said, you know, at any time, you know, we could stop, we could debrief.”

Experiences of clinician flexibility and personalization of therapy were contrasted with experiences of overly rigid therapy. Overemphasis on protocols created barriers, often because treatment did not feel personalized. One veteran described how a clinician’s task-oriented approach interfered with their ability to engage in TF-EBP:

They listened, but it just didn’t seem like they were listening, because they really wanted to stay on task… So, I felt like if the person was more concerned, or more sympathetic to the things that was also going on in my life at that present time, I think I would’ve felt more comfortable talking about what was the PTSD part, too.

Veterans valued shared decision-making prior to TF-EBP initiation. Veterans typically described being involved in a shared decision-making process prior to initiating TF-EBP. During these sessions, clinicians discussed treatment options and provided veterans with a variety of materials describing treatments (eg, pamphlets, websites, videos, statistics). Most veterans appreciated being able to reflect on and discuss treatment options with their clinicians. Being given time in and out of session to review was viewed as valuable and increased confidence in treatment choice. One veteran described their experience:

I was given the information, you know, they gave me handouts, PDFs, whatever was available, and let me read over it. I didn’t have to choose anything right then and there, you know, they let me sleep on it. And I got back to them after some thought.

However, some veterans felt overwhelmed by being presented with too much information and did not believe they knew enough to make a final treatment decision. One veteran described being asked to contribute to the treatment decision:

I definitely asked [the clinician] to weigh in on maybe what he thought was best, because—I mean, I don’t know… I’m not necessarily sure I know what I think is best. I think we’re just lucky I’m here, so if you can give me a solid and help me out here by telling me just based on what I’ve said to you and the things that I’ve gone through, what do you think?

Veterans who perceived that their treatment preferences were respected had a positive outlook on TF-EBP. As part of the shared-decision making process, veterans typically described being given choices among PTSD treatments. One way that preferences were respected was through clinicians tailoring treatment descriptions to a veteran’s unique symptoms, experiences, and values. In these cases, clinicians observed specific concerns and clearly linked treatment principles to those concerns. For example, one veteran described their clinician’s recommendation for PE: “The hardest thing for me is to do the normal things like grocery store or getting on a train or anything like that. And so, he suggested that [PE] would be a good idea.”

In other cases, veterans wanted the highest quality of treatment rather than a match between treatment principles and the veteran’s presentation, goals, or strengths. These veterans wanted the best treatment available for PTSD and valued research support, recommendations from clinical practice guidelines, or clinician confidence in the effectiveness of the treatment. One veteran described this perspective:

I just wanted to be able to really tackle it in the best way possible and in the most like aggressive way possible. And it seemed like PE really was going to, they said that it’s a difficult type of therapy, but I really just wanted to kind of do the best that I could to eradicate some of the issues that I was having.

When veterans perceived a lack of respect for their preferences, they were hesitant about TF-EBP. For some veterans, a generic pitch for a TF-EBP was detrimental in the absence of the personal connection between the treatment and their own symptoms, goals, or strengths. These veterans did not question whether the treatment was effective in general but did question whether the treatment was best for them. One veteran described the contrast between their clinician’s perspective and their own.

I felt like they felt very comfortable, very confident in [CPT] being the program, because it was comfortable for them. Because they did it several times. And maybe they had a lot of success with other individuals... but they were very comfortable with that one, as a provider, more than: Is this the best fit for [me]?

Some veterans perceived little concern for their preferences and a lack of choice in available treatments, which tended to perpetuate negative perceptions of TFEBP. These veterans described their lack of choices with frustration. Alternatives to TFEBP were described by these veterans as so undesirable that they did not believe they had a real choice:

[CPT] was the only decision they had. There was nothing else for PTSD. They didn’t offer anything else. So, I mean it wasn’t a decision. It was either … take treatment or don’t take treatment at all… Actually, I need to correct myself. So, there were 2 options, group therapy or CPT. I forgot about that. I’m not a big group guy so I chose the CPT.

Another veteran was offered a choice between therapeutic approaches, but all were delivered via telehealth (consistent with the transition to virtual services during the COVID-19 pandemic). For this veteran, not only was the distinction between approaches unclear, but the choice between approaches was unimportant compared to the mode of delivery.

This happened during COVID-19 and VA stopped seeing anybody physically, face-to-face. So my only option for therapy was [telehealth]… There was like 3 of them, and I tried to figure out, you know, from the layperson’s perspective, like: I don’t know which one to go with.

Veterans wanted to be asked about their cultural identity. Veterans valued when clinicians asked questions about cultural identity as part of their mental health treatment and listened to their cultural context. Cultural identity factors extended beyond factors such as race, ethnicity, gender, and sexual orientation to religion, military culture, and regionality. Veterans often described situations where they wished clinicians would ask the question or initiate conversations about culture. A veteran highlighted the importance of their faith but noted that it was a taboo topic. Their clinician did not say “we don’t go there,” but they “never dove into it either.” Another veteran expressed a desire for their clinician to ask questions about experiences in the National Guard and as an African American veteran:

If a provider was to say like: Oh, you know, it’s a stressful situation being a part of the military, being in the National Guard. You know, just asking questions about that. I think that would really go a long way… Being African American was difficult as well. And more so because of my region, I think… I felt like it would probably be an uncomfortable subject to speak on… I mean, it wasn’t anything that my providers necessarily did, it was more so just because it wasn’t brought up.

One common area of concern for veterans was a match between veteran and therapist demographics. When asked about how their cultural identity influenced treatment, several veterans described the relevance of therapist match. Much like questions about their own cultural identity, veterans valued being asked about identity preferences in clinicians (eg, gender or race matching), rather than having to bring up the preference themselves. One veteran described relief at this question being asked directly: “I was relieved when she had asked [whether I wanted a male or female clinician] primarily because I was going to ask that or bring that up somehow. But her asking that before me was a weight off my shoulders.”

Discussing cultural identity through treatment strengthened veterans’ engagement in therapy. Many veterans appreciated when analogies used in therapy were relevant to their cultural experiences and when clinicians understood their culture (eg, military culture, race, ethnicity, religious beliefs, sexual orientation). One veteran described how their clinician understood military culture and made connections between military culture and the rationale for TF-EBP, which strengthened the veteran’s buy-in for the treatment and alliance with the clinician:

At the beginning when she was explaining PTSD, and I remember she said that your brain needed to think this way when you were in the military because it was a way of protecting and surviving, so your brain was doing that in order for you to survive in whatever areas you were because there was danger. So, your brain had you thinking that way. But now, you’re not in those situations anymore. You’re not in danger. You’re not in the military, but your brain is still thinking you are, and that’s what PTSD generally does to you.

Specific elements of TF-EBP also provided opportunities to discuss and integrate important aspects of identity. This is accomplished in PE by assigning relevant in vivo exercises. In CPT, “connecting the dots” on how prior experiences influenced trauma-related stuck points achieved this element. One veteran described their experience with a clinician who was comfortable discussing the veteran’s sexual orientation and recognized the impacts of prior trauma on intimacy:

They’re very different, and there’s a lot of things that can be accepted in gay relationships that are not in straight ones. With all that said, I think [the PE therapist] did a fantastic job being not—like never once did she laugh or make an uncomfortable comment or say she didn’t wanna talk about something when like part of the reason I wanted to get into therapy is that my partner and I weren’t having sex unless I used alcohol.

Discussion

As part of a larger national qualitative investigation of the experiences of veterans who recently initiated TF-EBP, veterans discussed their experiences with therapy and mental health care that have important implications for continued process improvement.²¹ Three key areas for continued process improvement were identified: (1) providing information about the diverse range of mental health care services at the VA and the implications of this continuum of care; (2) consideration of veteran preferences in treatment decision-making, including the importance of perceived choice; and (3) incorporating cultural assessment and cultural responsiveness into case conceptualization and treatment.

One area of process improvement identified was increasing knowledge about different types of psychotherapy and the continuum of care available at the VA. Veterans in this study confused or conflated participating in psychotherapy with talking about mental health symptoms with a clinician (eg, assessment, disability evaluation). They were sometimes surprised that psychotherapy is an umbrella term referring to a variety of different modalities. The downstream impact of these misunderstandings was a perception of VA mental health care as nebulous. Veterans were surprised that all mental health practitioners were unable to provide the same care. Confusion may have been compounded by highly variable referral processes across VA.²⁴ To address this, clinicians have developed local educational resources and handouts for both veterans and referring clinicians from nonmental health and general mental health specialties.²⁵ Given the variability in referral processes both between and within VA medical centers, national dissemination of these educational materials may be more difficult compared to materials for TF-EBPs.²⁴ The VA started to use behavioral health interdisciplinary program (BHIP) teams, which are designed to be clinical homes for veterans connected with a central clinician who can explain and coordinate their mental health care as well as bring more consistency to the referral process.²⁶ The ongoing transition toward the BHIP model of mental health care at VA may provide the opportunity to consolidate and integrate knowledge about the VA approach to mental health care, potentially filling knowledge gaps.

A second area of process improvement focused on the shared decision-making process. Consistent with mental health initiatives, veterans generally believed they had received sufficient information about TF-EBP and engaged in shared decision-making with clinicians.^20,27 Veterans were given educational materials to review and had the opportunity to discuss these materials with clinicians. However, veterans described variability in the success of shared decision-making. Although veterans valued receiving accurate, comprehensible information to support treatment decisions, some preferred to defer to clinicians’ expertise regarding which treatment to pursue. While these veterans valued information, they also valued the expertise of clinicians in explaining why specific treatments would be beneficial. A key contributor to veterans satisfaction was assessing how veterans wanted to engage in the decision-making process and respecting those preferences.²⁸ Veterans approached shared decision-making differently, from making decisions independently after receiving information to relying solely on clinician recommendation. The process was most successful when clinicians articulated how their recommended treatment aligned with a veteran’s preferences, including recommendations based on specific values (eg, personalized match vs being the best). Another important consideration is ensuring veterans know they can receive a variety of different types of mental health services available in different modalities (eg, virtual vs in-person; group vs individual). When veterans did not perceive choice in treatment aspects important to them (typically despite having choices), they were less satisfied with their TF-EBP experience.

A final area of process improvement identified involves how therapists address important aspects of culture. Veterans often described mental health stigma coming from intersecting cultural identities and expressed appreciation when therapists helped them recognize the impact of these beliefs on treatment. Some veterans did not discuss important aspects of their identity with clinicians, including race/ethnicity, religion, and military culture. Veterans did not report negative interactions with clinicians or experiences suggesting it was inappropriate to discuss identity; however, they were reluctant to independently raise these identity factors. Strategies such as the ADDRESSING framework, a mnemonic acronym that describes a series of potentially relevant characteristics, can help clinicians comprehensively consider different aspects that may be relevant to veterans, modeling that discussion of relevant these characteristics is welcome in TF-EBP.²⁹ Veterans reported that making culturally relevant connections enhanced the TF-EBP experience, most commonly with military culture. These data support that TF-EBP delivery with attention to culture should be an integrated part of treatment, supporting engagement and therapeutic alliance.³⁰ The VA National Center for PTSD consultation program is a resource to support clinicians in assessing and incorporating relevant aspects of cultural identity.³¹ For example, the National Center for PTSD provides a guide for using case conceptualization to address patient reactions to race-based violence during PTSD treatment.³² Both manualized design and therapist certification training can reinforce that assessing and attending to case conceptualization (including identity factors) is an integral component of TF-EBP.^33,34

Limitations

While the current study has numerous strengths (eg, national veteran sampling, robust qualitative methods), results should be considered within the context of study limitations. First, veteran participants all received TF-EBP, and the perspectives of veterans who never initiate TF-EBP may differ. Despite the strong sampling approach, the study design is not intended to be generalizable to all veterans receiving TF-EBP for PTSD. Qualitative analysis yielded 15 themes, described in this study and prior research, consistent with recommendations.^21,22 This approach allows rich description of distinct focus areas that would not be possible in a single manuscript. Nonetheless, all veterans interviewed described their experiences in TF-EBP and general mental health care, the focus of the semistructured interview guide was on the experience of transitioning from other treatment to TF-EBP.

Conclusion

This study describes themes related to general mental health and TF-EBP process improvement as part of a larger study on transitions in PTSD care.^21,22 Veterans valued the fundamentals of therapy, including rapport and flexibility. Treatment-specific rapport (eg, pointing out treatment progress and effort in completing treatment components) and flexibility within the context of fidelity (ie, personalizing treatment while maintaining core treatment elements) may be most effective at engaging veterans in recommended PTSD treatments.^18,34 In addition to successes, themes suggest multiple opportunities for process improvement. Ongoing VA initiatives and priorities (ie, BHIP, shared decision-making, consultation services) aim to improve processes consistent with veteran recommendations. Future research is needed to evaluate the success of these and other programs to optimize access to and engagement in recommended PTSD treatments.

Trauma-focused evidence-based psychotherapies (TF-EBPs), including cognitive processing therapy (CPT) and prolonged exposure therapy (PE), are recommended treatments for posttraumatic stress disorder (PTSD) in clinical practice guidelines.^1-3 To increase initiation of these treatments, the US Department of Veterans Affairs (VA) used a large-scale dissemination and implementation effort to improve access to TF-EBP.^4,5 These efforts achieved modest success, increasing prevalence of TF-EBP from a handful of veterans in 2004 to an annual prevalence of 14.6% for CPT and 4.3% for PE in 2014.⁶

Throughout these efforts, qualitative studies have been used to better understand veterans’ perspectives on receiving TF-EBP care.^7-18 Barriers to initiation of and engagement in TF-EBP and PTSD care have been identified from these qualitative studies. One identified barrier was lack of knowledge—particularly lack of knowledge about what is meant by a PTSD diagnosis and available treatments.^7-10 Stigma (ie, automatic negative associations) toward mental health problems or seeking mental health care also has been identified as a barrier to initiation.^7,10-14 Perceptions of poor alignment between treatment and veteran goals, including lack of buy-in for the rationale, served as barriers to initiation and engagement.^8,15-18

Using prior qualitative work, numerous initiatives have been developed to reduce stigma, facilitate conversations about how treatment aligns with goals, and fill knowledge gaps, particularly through online resources and shared decision-making.^19,20 To better inform the state of veterans’ experiences with TF-EBP, a qualitative investigation was conducted involving veterans who recently initiated TF-EBP.

Consistent with recommendations for qualitative methods, this study extends prior work on transitions to TF-EBP by describing themes with a distinct focus on the experience of engaging with TF-EBP and mental health care.^21,22

Methods

The experiences of veterans who were transitioning into TF-EBPs were collected in semistructured interviews and analyzed. The semistructured interview guide was developed and refined in consultation with both qualitative methods experts and PTSD treatment experts to ensure that 6 content domains were appropriately queried: PTSD treatment options, cultural sensitivity of treatment, PTSD treatment selection, transition criteria, beliefs about stabilization treatment, and treatment needs/preferences.

Participants were identified using the VA Corporate Data Warehouse and included post-9/11 veterans who had recently initiated CPT or PE for the first time between September 1, 2021, and September 1, 2022. More details of participant selection are available in Holder et al.²¹ From a population of 10,814 patients, stratified random sampling generated a recruitment pool of 200 veterans for further outreach. The strata were defined such that this recruitment pool had similar proportions of demographic characteristics (ie, gender, race, ethnicity) to the population of eligible veterans, equivalent distributions of time to CPT or PE initiation (ie, 33.3% < 1 year, 33.3% 1-3 years, and 33.3% > 3 years), and adequate variability in TF-EBP type (ie, 66.7% CPT, 33.3% PE). A manual chart review in the recruitment pool excluded 12 veterans who did not initiate CPT or PE, 1 veteran with evidence of current active psychosis and/or cognitive impairment that would likely preclude comprehension of study materials, and 1 who was deceased.

Eligible veterans from the recruitment pool were contacted in groups of 25.

Veterans reported that they generally had a poor or “nebulous” understanding about the experience of psychotherapy. For example, veterans exhibited confusion about whether certain experiences were equivalent to participating in psychotherapy. They were sometimes unable to distinguish between interactions such as assessment, disability evaluations, peer support, and psychotherapy.

One veteran described how a clinician’s task-oriented approach interfered with their ability to engage in TF-EBP:

They listened, but it just didn’t seem like they were listening, because they really wanted to stay on task… So, I felt like if the person was more concerned, or more sympathetic to the things that was also going on in my life at that present time, I think I would’ve felt more comfortable talking about what was the PTSD part, too.

Veterans valued shared decision-making prior to TF-EBP initiation. Veterans typically described being involved in a shared decision-making process prior to initiating TF-EBP. During these sessions, clinicians discussed treatment options and provided veterans with a variety of materials describing treatments (eg, pamphlets, websites, videos, statistics). Most veterans appreciated being able to reflect on and discuss treatment options with their clinicians. Being given time in and out of session to review was viewed as valuable and increased confidence in treatment choice. One veteran described their experience:

I was given the information, you know, they gave me handouts, PDFs, whatever was available, and let me read over it. I didn’t have to choose anything right then and there, you know, they let me sleep on it. And I got back to them after some thought.

However, some veterans felt overwhelmed by being presented with too much information and did not believe they knew enough to make a final treatment decision. One veteran described being asked to contribute to the treatment decision:

I definitely asked [the clinician] to weigh in on maybe what he thought was best, because—I mean, I don’t know… I’m not necessarily sure I know what I think is best. I think we’re just lucky I’m here, so if you can give me a solid and help me out here by telling me just based on what I’ve said to you and the things that I’ve gone through, what do you think?

Veterans who perceived that their treatment preferences were respected had a positive outlook on TF-EBP. As part of the shared-decision making process, veterans typically described being given choices among PTSD treatments. One way that preferences were respected was through clinicians tailoring treatment descriptions to a veteran’s unique symptoms, experiences, and values. In these cases, clinicians observed specific concerns and clearly linked treatment principles to those concerns. For example, one veteran described their clinician’s recommendation for PE: “The hardest thing for me is to do the normal things like grocery store or getting on a train or anything like that. And so, he suggested that [PE] would be a good idea.”

In other cases, veterans wanted the highest quality of treatment rather than a match between treatment principles and the veteran’s presentation, goals, or strengths. These veterans wanted the best treatment available for PTSD and valued research support, recommendations from clinical practice guidelines, or clinician confidence in the effectiveness of the treatment. One veteran described this perspective:

I just wanted to be able to really tackle it in the best way possible and in the most like aggressive way possible. And it seemed like PE really was going to, they said that it’s a difficult type of therapy, but I really just wanted to kind of do the best that I could to eradicate some of the issues that I was having.

When veterans perceived a lack of respect for their preferences, they were hesitant about TF-EBP. For some veterans, a generic pitch for a TF-EBP was detrimental in the absence of the personal connection between the treatment and their own symptoms, goals, or strengths. These veterans did not question whether the treatment was effective in general but did question whether the treatment was best for them. One veteran described the contrast between their clinician’s perspective and their own.

I felt like they felt very comfortable, very confident in [CPT] being the program, because it was comfortable for them. Because they did it several times. And maybe they had a lot of success with other individuals... but they were very comfortable with that one, as a provider, more than: Is this the best fit for [me]?

Some veterans perceived little concern for their preferences and a lack of choice in available treatments, which tended to perpetuate negative perceptions of TFEBP. These veterans described their lack of choices with frustration. Alternatives to TFEBP were described by these veterans as so undesirable that they did not believe they had a real choice:

[CPT] was the only decision they had. There was nothing else for PTSD. They didn’t offer anything else. So, I mean it wasn’t a decision. It was either … take treatment or don’t take treatment at all… Actually, I need to correct myself. So, there were 2 options, group therapy or CPT. I forgot about that. I’m not a big group guy so I chose the CPT.

Another veteran was offered a choice between therapeutic approaches, but all were delivered via telehealth (consistent with the transition to virtual services during the COVID-19 pandemic). For this veteran, not only was the distinction between approaches unclear, but the choice between approaches was unimportant compared to the mode of delivery.

This happened during COVID-19 and VA stopped seeing anybody physically, face-to-face. So my only option for therapy was [telehealth]… There was like 3 of them, and I tried to figure out, you know, from the layperson’s perspective, like: I don’t know which one to go with.

Veterans wanted to be asked about their cultural identity. Veterans valued when clinicians asked questions about cultural identity as part of their mental health treatment and listened to their cultural context. Cultural identity factors extended beyond factors such as race, ethnicity, gender, and sexual orientation to religion, military culture, and regionality. Veterans often described situations where they wished clinicians would ask the question or initiate conversations about culture. A veteran highlighted the importance of their faith but noted that it was a taboo topic. Their clinician did not say “we don’t go there,” but they “never dove into it either.” Another veteran expressed a desire for their clinician to ask questions about experiences in the National Guard and as an African American veteran:

If a provider was to say like: Oh, you know, it’s a stressful situation being a part of the military, being in the National Guard. You know, just asking questions about that. I think that would really go a long way… Being African American was difficult as well. And more so because of my region, I think… I felt like it would probably be an uncomfortable subject to speak on… I mean, it wasn’t anything that my providers necessarily did, it was more so just because it wasn’t brought up.

One common area of concern for veterans was a match between veteran and therapist demographics. When asked about how their cultural identity influenced treatment, several veterans described the relevance of therapist match. Much like questions about their own cultural identity, veterans valued being asked about identity preferences in clinicians (eg, gender or race matching), rather than having to bring up the preference themselves. One veteran described relief at this question being asked directly: “I was relieved when she had asked [whether I wanted a male or female clinician] primarily because I was going to ask that or bring that up somehow. But her asking that before me was a weight off my shoulders.”

Discussing cultural identity through treatment strengthened veterans’ engagement in therapy. Many veterans appreciated when analogies used in therapy were relevant to their cultural experiences and when clinicians understood their culture (eg, military culture, race, ethnicity, religious beliefs, sexual orientation). One veteran described how their clinician understood military culture and made connections between military culture and the rationale for TF-EBP, which strengthened the veteran’s buy-in for the treatment and alliance with the clinician:

At the beginning when she was explaining PTSD, and I remember she said that your brain needed to think this way when you were in the military because it was a way of protecting and surviving, so your brain was doing that in order for you to survive in whatever areas you were because there was danger. So, your brain had you thinking that way. But now, you’re not in those situations anymore. You’re not in danger. You’re not in the military, but your brain is still thinking you are, and that’s what PTSD generally does to you.

Specific elements of TF-EBP also provided opportunities to discuss and integrate important aspects of identity. This is accomplished in PE by assigning relevant in vivo exercises. In CPT, “connecting the dots” on how prior experiences influenced trauma-related stuck points achieved this element. One veteran described their experience with a clinician who was comfortable discussing the veteran’s sexual orientation and recognized the impacts of prior trauma on intimacy:

They’re very different, and there’s a lot of things that can be accepted in gay relationships that are not in straight ones. With all that said, I think [the PE therapist] did a fantastic job being not—like never once did she laugh or make an uncomfortable comment or say she didn’t wanna talk about something when like part of the reason I wanted to get into therapy is that my partner and I weren’t having sex unless I used alcohol.

Discussion

As part of a larger national qualitative investigation of the experiences of veterans who recently initiated TF-EBP, veterans discussed their experiences with therapy and mental health care that have important implications for continued process improvement.²¹ Three key areas for continued process improvement were identified: (1) providing information about the diverse range of mental health care services at the VA and the implications of this continuum of care; (2) consideration of veteran preferences in treatment decision-making, including the importance of perceived choice; and (3) incorporating cultural assessment and cultural responsiveness into case conceptualization and treatment.

One area of process improvement identified was increasing knowledge about different types of psychotherapy and the continuum of care available at the VA. Veterans in this study confused or conflated participating in psychotherapy with talking about mental health symptoms with a clinician (eg, assessment, disability evaluation). They were sometimes surprised that psychotherapy is an umbrella term referring to a variety of different modalities. The downstream impact of these misunderstandings was a perception of VA mental health care as nebulous. Veterans were surprised that all mental health practitioners were unable to provide the same care. Confusion may have been compounded by highly variable referral processes across VA.²⁴ To address this, clinicians have developed local educational resources and handouts for both veterans and referring clinicians from nonmental health and general mental health specialties.²⁵ Given the variability in referral processes both between and within VA medical centers, national dissemination of these educational materials may be more difficult compared to materials for TF-EBPs.²⁴ The VA started to use behavioral health interdisciplinary program (BHIP) teams, which are designed to be clinical homes for veterans connected with a central clinician who can explain and coordinate their mental health care as well as bring more consistency to the referral process.²⁶ The ongoing transition toward the BHIP model of mental health care at VA may provide the opportunity to consolidate and integrate knowledge about the VA approach to mental health care, potentially filling knowledge gaps.

A second area of process improvement focused on the shared decision-making process. Consistent with mental health initiatives, veterans generally believed they had received sufficient information about TF-EBP and engaged in shared decision-making with clinicians.^20,27 Veterans were given educational materials to review and had the opportunity to discuss these materials with clinicians. However, veterans described variability in the success of shared decision-making. Although veterans valued receiving accurate, comprehensible information to support treatment decisions, some preferred to defer to clinicians’ expertise regarding which treatment to pursue. While these veterans valued information, they also valued the expertise of clinicians in explaining why specific treatments would be beneficial. A key contributor to veterans satisfaction was assessing how veterans wanted to engage in the decision-making process and respecting those preferences.²⁸ Veterans approached shared decision-making differently, from making decisions independently after receiving information to relying solely on clinician recommendation. The process was most successful when clinicians articulated how their recommended treatment aligned with a veteran’s preferences, including recommendations based on specific values (eg, personalized match vs being the best). Another important consideration is ensuring veterans know they can receive a variety of different types of mental health services available in different modalities (eg, virtual vs in-person; group vs individual). When veterans did not perceive choice in treatment aspects important to them (typically despite having choices), they were less satisfied with their TF-EBP experience.

A final area of process improvement identified involves how therapists address important aspects of culture. Veterans often described mental health stigma coming from intersecting cultural identities and expressed appreciation when therapists helped them recognize the impact of these beliefs on treatment. Some veterans did not discuss important aspects of their identity with clinicians, including race/ethnicity, religion, and military culture. Veterans did not report negative interactions with clinicians or experiences suggesting it was inappropriate to discuss identity; however, they were reluctant to independently raise these identity factors. Strategies such as the ADDRESSING framework, a mnemonic acronym that describes a series of potentially relevant characteristics, can help clinicians comprehensively consider different aspects that may be relevant to veterans, modeling that discussion of relevant these characteristics is welcome in TF-EBP.²⁹ Veterans reported that making culturally relevant connections enhanced the TF-EBP experience, most commonly with military culture. These data support that TF-EBP delivery with attention to culture should be an integrated part of treatment, supporting engagement and therapeutic alliance.³⁰ The VA National Center for PTSD consultation program is a resource to support clinicians in assessing and incorporating relevant aspects of cultural identity.³¹ For example, the National Center for PTSD provides a guide for using case conceptualization to address patient reactions to race-based violence during PTSD treatment.³² Both manualized design and therapist certification training can reinforce that assessing and attending to case conceptualization (including identity factors) is an integral component of TF-EBP.^33,34

Limitations

While the current study has numerous strengths (eg, national veteran sampling, robust qualitative methods), results should be considered within the context of study limitations. First, veteran participants all received TF-EBP, and the perspectives of veterans who never initiate TF-EBP may differ. Despite the strong sampling approach, the study design is not intended to be generalizable to all veterans receiving TF-EBP for PTSD. Qualitative analysis yielded 15 themes, described in this study and prior research, consistent with recommendations.^21,22 This approach allows rich description of distinct focus areas that would not be possible in a single manuscript. Nonetheless, all veterans interviewed described their experiences in TF-EBP and general mental health care, the focus of the semistructured interview guide was on the experience of transitioning from other treatment to TF-EBP.

Conclusion

This study describes themes related to general mental health and TF-EBP process improvement as part of a larger study on transitions in PTSD care.^21,22 Veterans valued the fundamentals of therapy, including rapport and flexibility. Treatment-specific rapport (eg, pointing out treatment progress and effort in completing treatment components) and flexibility within the context of fidelity (ie, personalizing treatment while maintaining core treatment elements) may be most effective at engaging veterans in recommended PTSD treatments.^18,34 In addition to successes, themes suggest multiple opportunities for process improvement. Ongoing VA initiatives and priorities (ie, BHIP, shared decision-making, consultation services) aim to improve processes consistent with veteran recommendations. Future research is needed to evaluate the success of these and other programs to optimize access to and engagement in recommended PTSD treatments.

Trauma-focused evidence-based psychotherapies (TF-EBPs), including cognitive processing therapy (CPT) and prolonged exposure therapy (PE), are recommended treatments for posttraumatic stress disorder (PTSD) in clinical practice guidelines.^1-3 To increase initiation of these treatments, the US Department of Veterans Affairs (VA) used a large-scale dissemination and implementation effort to improve access to TF-EBP.^4,5 These efforts achieved modest success, increasing prevalence of TF-EBP from a handful of veterans in 2004 to an annual prevalence of 14.6% for CPT and 4.3% for PE in 2014.⁶

Throughout these efforts, qualitative studies have been used to better understand veterans’ perspectives on receiving TF-EBP care.^7-18 Barriers to initiation of and engagement in TF-EBP and PTSD care have been identified from these qualitative studies. One identified barrier was lack of knowledge—particularly lack of knowledge about what is meant by a PTSD diagnosis and available treatments.^7-10 Stigma (ie, automatic negative associations) toward mental health problems or seeking mental health care also has been identified as a barrier to initiation.^7,10-14 Perceptions of poor alignment between treatment and veteran goals, including lack of buy-in for the rationale, served as barriers to initiation and engagement.^8,15-18

Using prior qualitative work, numerous initiatives have been developed to reduce stigma, facilitate conversations about how treatment aligns with goals, and fill knowledge gaps, particularly through online resources and shared decision-making.^19,20 To better inform the state of veterans’ experiences with TF-EBP, a qualitative investigation was conducted involving veterans who recently initiated TF-EBP. Themes directly related to transitions to TF-EBP were identified; however, all veterans interviewed also described their experiences with TFEBP engagement and mental health care. Consistent with recommendations for qualitative methods, this study extends prior work on transitions to TF-EBP by describing themes with a distinct focus on the experience of engaging with TF-EBP and mental health care.^21,22

Methods

The experiences of veterans who were transitioning into TF-EBPs were collected in semistructured interviews and analyzed. The semistructured interview guide was developed and refined in consultation with both qualitative methods experts and PTSD treatment experts to ensure that 6 content domains were appropriately queried: PTSD treatment options, cultural sensitivity of treatment, PTSD treatment selection, transition criteria, beliefs about stabilization treatment, and treatment needs/preferences.

Participants were identified using the VA Corporate Data Warehouse and included post-9/11 veterans who had recently initiated CPT or PE for the first time between September 1, 2021, and September 1, 2022. More details of participant selection are available in Holder et al.²¹ From a population of 10,814 patients, stratified random sampling generated a recruitment pool of 200 veterans for further outreach. The strata were defined such that this recruitment pool had similar proportions of demographic characteristics (ie, gender, race, ethnicity) to the population of eligible veterans, equivalent distributions of time to CPT or PE initiation (ie, 33.3% < 1 year, 33.3% 1-3 years, and 33.3% > 3 years), and adequate variability in TF-EBP type (ie, 66.7% CPT, 33.3% PE). A manual chart review in the recruitment pool excluded 12 veterans who did not initiate CPT or PE, 1 veteran with evidence of current active psychosis and/or cognitive impairment that would likely preclude comprehension of study materials, and 1 who was deceased.

Eligible veterans from the recruitment pool were contacted in groups of 25. First, a recruitment letter with study information and instructions to opt-out of further contact was mailed or emailed to veterans. After 2 weeks, veterans who had not responded were contacted by phone up to 3 times. Veterans interested in participating were scheduled for a 1-time visit that included verbal consent and the qualitative interview. Metrics were established a priori to ensure an adequately diverse and inclusive sample. Specifically, a minimum number of racial and/or ethnic minority veterans (33%) and women veterans (20%) were sought. Equal distribution across the 3 categories of time from first mental health visit to CPT/PE initiation also was targeted. Throughout enrollment, recruitment efforts were adapted to meet these metrics in the emerging sample. While the goal was to generate a diverse and inclusive sample using these methods, the sample was not intended to be representative of the population.

Of the 186 eligible participants, 21 declined participation and 26 could not be reached. The targeted sample was reached after exhausting contact for 47 veterans and contacting 80 veterans for a final response rate of 40% among fully contacted veterans and 27% among veterans with any contact. The final sample included 30 veterans who received CPT or PE in VA facilities (Table).

After veterans provided verbal consent for study participation, sociodemographic information was verbally reported, and a 30- to 60-minute semistructured qualitative phone interview was recorded and transcribed. Veterans received $40 for participation. All procedures were approved by the University of California San Francisco Institutional Review Board.

Qualitative Data Analysis

Rapid analysis procedures were used to analyze qualitative data. This approach is suitable for focused, moderately structured qualitative analyses in health services research and facilitates rapid dissemination to stakeholders.²³ The qualitative analysts were 2 clinical psychologists with expertise in PTSD treatment (NH primary and RR secondary). Consistent with rapid analysis procedures, analysts prepared a templated summary (including relevant quotations) of each interview, organized by the prespecified content domains. Interviews were summarized independently, compared to ensure consistency, and discrepancies were resolved through review of the interview source materials. Individual summary templates were combined into a master analytic matrix to facilitate the identification of patterns and delineation of themes. Analysts routinely met to identify, discuss, and refine preliminary themes, revisiting source materials to reach consensus as needed.

Results

Fifteen themes were identified and organized into 2 distinct focus areas: themes directly related to the transition to TF-EBP (8 themes) and themes related to veterans’ experiences with TF-EBP and general mental health care with potential process-improvement implications (7 themes).²¹ Seven themes were identified related to experiences with TF-EBP engagement and VA mental health care. The 7 themes related to TF-EBP engagement and VA mental health care themes are summarized with exemplary quotations.

Veterans want a better understanding of psychotherapy and engaging with VA mental health. Veterans reported that they generally had a poor or “nebulous” understanding about the experience of psychotherapy. For example, veterans exhibited confusion about whether certain experiences were equivalent to participating in psychotherapy. They were sometimes unable to distinguish between interactions such as assessment, disability evaluations, peer support, and psychotherapy. One veteran described a conversation with a TFEBP therapist about prior treatment:

She [asked], have you ever been, or gone through a therapy to begin with? And I, I said, well I just chatted with somebody. And she said that’s not, that’s not therapy. So, I was like, oh, it’s not? That’s not what people do?

Veterans were surprised the VA offered a diverse range of psychotherapy interventions, rather than simply therapy. They did not realize there were different types of psychotherapy. As a result, veterans were not aware that some VA mental practitioners have specialty training and certification to provide treatment matched to specific diagnoses or needs. They thought that all clinicians could provide the same care. One veteran described their understanding:

I just figured all mental health people are mental health people. I didn’t have a better understanding of the system and all the different levels and how it plays out and specialties and things like that. Which, I guess, I should have because you have a primary care doctor, but then you have specialists in all these other different sectors that specialize in one particular area. I guess that should’ve been common sense, but it wasn’t.

Stigma was a barrier to seeking and engaging in mental health care. Veterans discovered they had to overcome stigma associated with seeking and engaging in mental health treatment. Military culture was often discussed as promoting stigma regarding mental health treatment. Specifically, veterans described that seeking treatment meant “either, I’m weak or I’m gonna be seen as weak.” In active-duty settings, the strategy for dealing with mental health symptoms was to “leave those feelings, you push ‘em aside,” an approach highly inconsistent with TF-EBP. In some cases, incorrect information about the VA and PTSD was presented as part of discharge from the military, leading to long-term skepticism of the VA and PTSD treatment. One veteran described his experience as part of a class on the VA compensation and pension assessment process for service-connected disabilities during his military discharge:

[A fellow discharging soldier asked] what about like PTSD, gettin’ rated for PTSD. I hear they take our weapons and stuff like we can’t own firearms and all that stuff. And [the instructor] was like, well, yes that’s a thing. He didn’t explain it like if you get compensated for PTSD you don’t lose your rights to carry a firearm or to have, to be able to go hunting.

Importantly, veterans often described how other identities (eg, race, ethnicity, gender, region of origin) interacted with military culture to enhance stigma. Hearing messaging from multiple sources reinforced beliefs that mental health treatment is inappropriate or is associated with weakness:

As a first-generation Italian, I was always taught keep your feelings to yourself. Never talk outside your family. Never bring up problems to other people and stuff like that. Same with the military. And then the old stigma working in [emergency medical services] and public safety, you’re weak if you get help.

The fundamentals of therapy, including rapport and flexibility, were important. Veterans valued nonspecific therapy factors, genuine empathy, building trust, being honest about treatment, personality, and rapport. These characteristics were almost universally described as particularly important:

I liked the fact that she made it personable and she cared. It wasn’t just like, here, we’re gonna start this. She explained it in the ways I could understand, not in medical terms, so to speak, but that’s what I liked about her. She really cared about what she did and helping me.

Flexibility was viewed as an asset, particularly when clinicians acknowledged veteran autonomy. A consistent example was when veterans were able to titrate trauma disclosure. One veteran described this flexible treatment experience: “She was right there in the room, she said, you know, at any time, you know, we could stop, we could debrief.”

Experiences of clinician flexibility and personalization of therapy were contrasted with experiences of overly rigid therapy. Overemphasis on protocols created barriers, often because treatment did not feel personalized. One veteran described how a clinician’s task-oriented approach interfered with their ability to engage in TF-EBP:

They listened, but it just didn’t seem like they were listening, because they really wanted to stay on task… So, I felt like if the person was more concerned, or more sympathetic to the things that was also going on in my life at that present time, I think I would’ve felt more comfortable talking about what was the PTSD part, too.

Veterans valued shared decision-making prior to TF-EBP initiation. Veterans typically described being involved in a shared decision-making process prior to initiating TF-EBP. During these sessions, clinicians discussed treatment options and provided veterans with a variety of materials describing treatments (eg, pamphlets, websites, videos, statistics). Most veterans appreciated being able to reflect on and discuss treatment options with their clinicians. Being given time in and out of session to review was viewed as valuable and increased confidence in treatment choice. One veteran described their experience:

I was given the information, you know, they gave me handouts, PDFs, whatever was available, and let me read over it. I didn’t have to choose anything right then and there, you know, they let me sleep on it. And I got back to them after some thought.

However, some veterans felt overwhelmed by being presented with too much information and did not believe they knew enough to make a final treatment decision. One veteran described being asked to contribute to the treatment decision:

I definitely asked [the clinician] to weigh in on maybe what he thought was best, because—I mean, I don’t know… I’m not necessarily sure I know what I think is best. I think we’re just lucky I’m here, so if you can give me a solid and help me out here by telling me just based on what I’ve said to you and the things that I’ve gone through, what do you think?

Veterans who perceived that their treatment preferences were respected had a positive outlook on TF-EBP. As part of the shared-decision making process, veterans typically described being given choices among PTSD treatments. One way that preferences were respected was through clinicians tailoring treatment descriptions to a veteran’s unique symptoms, experiences, and values. In these cases, clinicians observed specific concerns and clearly linked treatment principles to those concerns. For example, one veteran described their clinician’s recommendation for PE: “The hardest thing for me is to do the normal things like grocery store or getting on a train or anything like that. And so, he suggested that [PE] would be a good idea.”

In other cases, veterans wanted the highest quality of treatment rather than a match between treatment principles and the veteran’s presentation, goals, or strengths.

These veterans described their lack of choices with frustration. Alternatives to TFEBP were described by these veterans as so undesirable that they did not believe they had a real choice:

[CPT] was the only decision they had. There was nothing else for PTSD. They didn’t offer anything else. So, I mean it wasn’t a decision. It was either … take treatment or don’t take treatment at all… Actually, I need to correct myself. So, there were 2 options, group therapy or CPT. I forgot about that. I’m not a big group guy so I chose the CPT.

Another veteran was offered a choice between therapeutic approaches, but all were delivered via telehealth (consistent with the transition to virtual services during the COVID-19 pandemic).

You’re not in the military, but your brain is still thinking you are, and that’s what PTSD generally does to you.

Specific elements of TF-EBP also provided opportunities to discuss and integrate important aspects of identity. This is accomplished in PE by assigning relevant in vivo exercises. In CPT, “connecting the dots” on how prior experiences influenced trauma-related stuck points achieved this element. One veteran described their experience with a clinician who was comfortable discussing the veteran’s sexual orientation and recognized the impacts of prior trauma on intimacy:

They’re very different, and there’s a lot of things that can be accepted in gay relationships that are not in straight ones. With all that said, I think [the PE therapist] did a fantastic job being not—like never once did she laugh or make an uncomfortable comment or say she didn’t wanna talk about something when like part of the reason I wanted to get into therapy is that my partner and I weren’t having sex unless I used alcohol.

Discussion

As part of a larger national qualitative investigation of the experiences of veterans who recently initiated TF-EBP, veterans discussed their experiences with therapy and mental health care that have important implications for continued process improvement.²¹ Three key areas for continued process improvement were identified: (1) providing information about the diverse range of mental health care services at the VA and the implications of this continuum of care; (2) consideration of veteran preferences in treatment decision-making, including the importance of perceived choice; and (3) incorporating cultural assessment and cultural responsiveness into case conceptualization and treatment.

Confusion may have been compounded by highly variable referral processes across VA.²⁴ To address this, clinicians have developed local educational resources and handouts for both veterans and referring clinicians from nonmental health and general mental health specialties.²⁵ Given the variability in referral processes both between and within VA medical centers, national dissemination of these educational materials may be more difficult compared to materials for TF-EBPs.²⁴ The VA started to use behavioral health interdisciplinary program (BHIP) teams, which are designed to be clinical homes for veterans connected with a central clinician who can explain and coordinate their mental health care as well as bring more consistency to the referral process.²⁶ The ongoing transition toward the BHIP model of mental health care at VA may provide the opportunity to consolidate and integrate knowledge about the VA approach to mental health care, potentially filling knowledge gaps.

A second area of process improvement focused on the shared decision-making process. Consistent with mental health initiatives, veterans generally believed they had received sufficient information about TF-EBP and engaged in shared decision-making with clinicians.^20,27 Veterans were given educational materials to review and had the opportunity to discuss these materials with clinicians. However, veterans described variability in the success of shared decision-making. Although veterans valued receiving accurate, comprehensible information to support treatment decisions, some preferred to defer to clinicians’ expertise regarding which treatment to pursue. While these veterans valued information, they also valued the expertise of clinicians in explaining why specific treatments would be beneficial. A key contributor to veterans satisfaction was assessing how veterans wanted to engage in the decision-making process and respecting those preferences.²⁸ Veterans approached shared decision-making differently, from making decisions independently after receiving information to relying solely on clinician recommendation. The process was most successful when clinicians articulated how their recommended treatment aligned with a veteran’s preferences, including recommendations based on specific values (eg, personalized match vs being the best). Another important consideration is ensuring veterans know they can receive a variety of different types of mental health services available in different modalities (eg, virtual vs in-person; group vs individual). When veterans did not perceive choice in treatment aspects important to them (typically despite having choices), they were less satisfied with their TF-EBP experience.

A final area of process improvement identified involves how therapists address important aspects of culture. Veterans often described mental health stigma coming from intersecting cultural identities and expressed appreciation when therapists helped them recognize the impact of these beliefs on treatment. Some veterans did not discuss important aspects of their identity with clinicians, including race/ethnicity, religion, and military culture. Veterans did not report negative interactions with clinicians or experiences suggesting it was inappropriate to discuss identity; however, they were reluctant to independently raise these identity factors. Strategies such as the ADDRESSING framework, a mnemonic acronym that describes a series of potentially relevant characteristics, can help clinicians comprehensively consider different aspects that may be relevant to veterans, modeling that discussion of relevant these characteristics is welcome in TF-EBP.²⁹ Veterans reported that making culturally relevant connections enhanced the TF-EBP experience, most commonly with military culture. These data support that TF-EBP delivery with attention to culture should be an integrated part of treatment, supporting engagement and therapeutic alliance.³⁰ The VA National Center for PTSD consultation program is a resource to support clinicians in assessing and incorporating relevant aspects of cultural identity.³¹ For example, the National Center for PTSD provides a guide for using case conceptualization to address patient reactions to race-based violence during PTSD treatment.³² Both manualized design and therapist certification training can reinforce that assessing and attending to case conceptualization (including identity factors) is an integral component of TF-EBP.^33,34

Limitations

While the current study has numerous strengths (eg, national veteran sampling, robust qualitative methods), results should be considered within the context of study limitations. First, veteran participants all received TF-EBP, and the perspectives of veterans who never initiate TF-EBP may differ. Despite the strong sampling approach, the study design is not intended to be generalizable to all veterans receiving TF-EBP for PTSD. Qualitative analysis yielded 15 themes, described in this study and prior research, consistent with recommendations.^21,22 This approach allows rich description of distinct focus areas that would not be possible in a single manuscript. Nonetheless, all veterans interviewed described their experiences in TF-EBP and general mental health care, the focus of the semistructured interview guide was on the experience of transitioning from other treatment to TF-EBP.

Conclusion

This study describes themes related to general mental health and TF-EBP process improvement as part of a larger study on transitions in PTSD care.^21,22 Veterans valued the fundamentals of therapy, including rapport and flexibility. Treatment-specific rapport (eg, pointing out treatment progress and effort in completing treatment components) and flexibility within the context of fidelity (ie, personalizing treatment while maintaining core treatment elements) may be most effective at engaging veterans in recommended PTSD treatments.^18,34 In addition to successes, themes suggest multiple opportunities for process improvement. Ongoing VA initiatives and priorities (ie, BHIP, shared decision-making, consultation services) aim to improve processes consistent with veteran recommendations. Future research is needed to evaluate the success of these and other programs to optimize access to and engagement in recommended PTSD treatments.

What does a successful military-to-civilian transition look like? How do we know if a veteran is sinking, treading water, or swimming? Two recent studies by the Penn State University Clearinghouse for Military Family Readiness sought to answer to those questions and more while determining how and when is the right time to step in to help a veteran in need.

The research analyzed The Veterans Metrics Initiative data (TVMI). This longitudinal study surveyed 9566 men and women who left active duty in 2016 over 3 years, answering questions about deployment histories, adverse childhood experiences (ACEs) and exposure to combat. They also reported whether they had symptoms related to anxiety and depression. 

The TVMI study found that ACEs predicted poor outcomes early on and when combined with warfare experience dramatically increased the likelihood of mental health issues, including posttraumatic stress disorder (PTSD), anxiety, and depression; moral injury impacted adjustment to civilian life (the degree varied by gender); and, many veterans have a “growth outlook” as a result of a trauma or crisis they experienced.

The TVMI study found that almost all veterans use transition resources in the first 2 years after military separation. Beyond that, however, those in high-risk categories (eg, PTSD and cumulative trauma experiences) need continued support. This may come in the form of a universal screener and linking it to a navigation infrastructure (eg, AmericaServes), “thereby identifying risk factors early and providing targeted supports, interventions, and components.”

Veterans often face a series of simultaneous challenges as they return to civilian life. Among them include getting used to family and friends again, finding jobs, losing their military identity, structure, and perhaps leaving military friends behind. In addition, veterans are likely dealing with physical and mental health challenges, which can significantly influence how well they readjust to civilian life and lead to inconsistency experiences for each individual.

A 2019 survey from the Pew Research Center found about 40% of veterans who suffered from PTSD said they frequently had difficulty dealing with the lack of structure in civilian life, compared with 5% of those who do not have PTSD. Another survey cited a large majority (78%) of pre-9/11 veterans said their readjustment was very or somewhat easy. However, 26% said adjusting to civilian life was difficult.

In 2011, 4 variables were identified that predicted easy civilian life re-entry: being an officer; having a consistently clear understanding of the missions while in the service; being a college graduate; and, for post-9/11 veterans, attending religious services frequently. Six variables were associated with a diminished probability of an easy transition: having had a traumatic experience; being seriously injured; serving in the post-9/11 era; serving in a combat zone; serving with someone who was killed or injured; and, for post-9/11 veterans, being married while in the service.

The probabilities of an easy re-entry dropped from 82% for those who did not experience a traumatic event to 56% for those who did—the largest change noted in the 2011 study.

The second Penn State study evaluated a model framework with a lifespan development perspective. The study surveyed veterans on their self-reported satisfaction or symptoms in 7 domains of well-being: employment, education, financial, legal problems, social, physical health, and mental health. Within 3 months of separation , 41% of respondents fell into the “problematic” category for the mental health domain. However, by 30 to 33 months postseparation, this proportion dropped to 34%. During the same period, the proportion of veterans in the at risk category increased from 28% at Wave 1 to 37% at Wave 6. About 30% of veterans fell into the successful category for symptoms across the 3 examined waves. Almost 60% were in the successful category across the 3 time points.

Both Penn State studies emphasize the importance of viewing veterans as individuals on their own timelines.

“These findings underscore that the transition to civilian life is not a single moment, but a process influenced by experiences across the life span,” said Mary M. Mitchell, research professor at the Clearinghouse and lead author on the predictors study. “By following veterans over 3 years, we were able to see how patterns emerge that would be invisible in a one-time survey.”

Current conceptualization “assumes that there are commonalities across veterans when evaluating the success of the transition to civilian life,” according to the authors of the framework study. “However, each veteran likely has his or her view of what a successful transition constitutes, and he or she may weigh domains differently when considering his or her own transition.”

The research highlights the need to find ways to encourage veterans to seek help—and not just in the first year, which is often the most stressful. The Pew Research Center survey identified a “significant break from the past,” in that nearly 70% of post-9/11 veterans said their superiors made them feel comfortable about seeking help with emotional issues resulting from their military service. 

However, ≤ 8% veterans in the TVMI study used any health programs, even when they screened positive for mental health problems. Veterans who did use counseling services, however, improved their depression symptoms. Engaging veterans at various time points could help keep mental health problems from worsening during—and beyond—the transition.

TOPLINE:

Energy insecurity, the inability to meet household energy needs, was associated with more than twice the odds of having depression and anxiety symptoms than energy security in US adults, a new cross-sectional study showed.

METHODOLOGY:

• Using data from the US Census Bureau's online Household Pulse Survey, administered between 2022 and 2024, researchers conducted a cross-sectional study with a weighted population of > 187 million US adults (51% women; 64% White, 16% Hispanic, 10% Black, and 5% Asian). About a quarter of the population was in each of 4 age groups: 18-34 years, 35-49 years, 50-64 years, and ≥ 65 years.
• Three indicators of energy insecurity—inability to pay energy bills, maintaining unsafe/unhealthy home temperatures, and forgoing expenses on basic necessities to pay energy bills—were assessed individually and as a composite measure.
• Mental health was assessed using modified versions of the 2-item Patient Health Questionnaire for depression and the 2-item Generalized Anxiety Disorder scale for anxiety.
• The analysis was adjusted for other social determinants of health, including unemployment, housing instability, and food insecurity. Covariates included a wide range of factors, such as age, educational level, sex, and annual household income.

TAKEAWAY:

• In all, > 43% of the population reported having ≥ 1 form of energy security; around 22% reported being unable to pay energy bills, 22% maintained unsafe home temperatures, and nearly 34% forewent spending on basic necessities to pay energy bills.
• Individuals who gave up spending on basic necessities to pay energy bills had higher odds of anxiety (adjusted odds ratio [aOR], 1.79) and depression (aOR, 1.74) than those who did not.
• Adults with energy insecurity on the composite measure had higher odds for anxiety (aOR, 2.29) and depression (aOR, 2.31) than those with energy security.
• Food insecurity was also associated with poorer mental health, with higher odds for symptoms of depression (aOR, 2.05) and anxiety (aOR, 2.07).

IN PRACTICE:

"Despite its high prevalence, energy insecurity remains underrecognized in public health and policy intervention strategies," the investigators wrote.

"These findings suggest that energy insecurity is a widespread and important factor associated with mental health symptoms and may warrant consideration in efforts to reduce adverse mental health outcomes," they added.

SOURCE:

This study was led by Michelle Graf, PhD, Carter School of Public Policy, Georgia Institute of Technology, Atlanta. It was published online on October 27 in JAMA Network Open.

LIMITATIONS:

The cross-sectional nature of the data limited causal interference and increased the possibility of reverse causality. The questionnaire captured subjective interpretations of unsafe and unhealthy indoor temperatures, which may have varied among respondents. Additionally, the recall periods for energy insecurity and mental health outcomes were different.

DISCLOSURES:

The investigators reported no relevant conflicts of interest.

More than 38 million people in the United States (12%) have diabetes mellitus (DM), though 1 in 5 are unaware they have DM.¹ The prevalence among veterans is even more substantial, impacting nearly 25% of those who received care from the US Department of Veterans Affairs (VA).² DM can lead to increased health care costs in addition to various complications (eg, cardiovascular, renal), especially if left uncontrolled.^1,3 similar impact is found in the perioperative period (defined as at or around the time of an operation), as multiple studies have found that uncontrolled preoperative DM can result in worsened surgical outcomes, including longer hospital stays, more infectious complications, and higher perioperative mortality.^4-6

In contrast, adequate glycemic control assessed with blood glucose levels has been shown to decrease the incidence of postoperative infections.⁷ Optimizing glycemic control during hospital stays, especially postsurgery, has become the standard of care, with most health systems establishing specific protocols. In current literature, most studies examining DM management in the perioperative period are focused on postoperative care, with little attention to the preoperative period.^4,6,7

One study found that patients with poor presurgery glycemic control assessed by hemoglobin A_1c (HbA_1c) levels were more likely to remain hyperglycemic during and after surgery. 8 Blood glucose levels < 200 mg/dL can lead to an increased risk of infection and impaired wound healing, meaning a well-controlled HbA_1c before a procedure serves as a potential factor for success.⁹ The 2025 American Diabetes Association (ADA) Standards of Care (SOC) recommendation is to target HbA_1c < 8% whenever possible, and some health systems require lower levels (eg, < 7% or 7.5%).¹⁰ With that goal in mind and knowing that preoperative hyperglycemia has been shown to be a contributing factor in the delay or cancellation of surgical cases, an argument can be made that attention to preoperative DM management also should be a focus for health care systems performing surgeries.^8,9,11

Attention to glucose control during preoperative care offers an opportunity to screen for DM in patients who may not have been screened otherwise and to standardize perioperative DM management. Since DM disproportionately impacts veterans, this is a pertinent issue to the VA. Veterans can be more susceptible to complications if DM is left uncontrolled prior to surgery. To determine readiness for surgery and control of comorbid conditions such as DM before a planned surgery, facilities often perform a preoperative clinic assessment, often in a multidisciplinary clinic.

At Veteran Health Indiana (VHI), a presurgery clinic visit involving the primary surgery service (physician, nurse practitioner, and/or a physician assistant) is conducted 1 to 2 months prior to the planned procedure to determine whether a patient is ready for surgery. During this visit, patients receive a packet with instructions for various tasks and medications, such as applying topical antibiotic prophylaxis on the anticipated surgical site. This is documented in the form of a note in the VHI Computerized Patient Record System (CPRS). The medication instructions are provided according to the preferences of the surgical team. These may be templated notes that contain general directions on the timing and dosing of specific medications, in addition to instructions for holding or reducing doses when appropriate. The instructions can be tailored by the team conducting the preoperative visit (eg, “Take 20 units of insulin glargine the day before surgery” vs “Take half of your long-acting insulin the night before surgery”). Specific to DM, VHI has a nurse-driven day of surgery glucose assessment where point-of-care blood glucose is collected during preoperative holding for most patients.

There is limited research assessing the level of preoperative glycemic control and the incidence of complications in a veteran population. The objective of this study was to gain a baseline understanding of what, if any, standardization exists for preoperative instructions for DM medications and to assess the level of preoperative glycemic control and postoperative complications in patients with DM undergoing major elective surgical procedures.

Methods

This retrospective, single-center chart review was conducted at VHI. The Indiana University and VHI institutional review boards determined that this quality improvement project was exempt from review.

The primary outcome was the number of patients with surgical procedures delayed or canceled due to hyperglycemia or hypoglycemia. Hyperglycemia was defined as blood glucose > 180 mg/dL and hypoglycemia was defined as < 70 mg/dL, slight variations from the current ADA SOC preoperative specific recommendation of a blood glucose reading of 100 to 180 mg/dL within 4 hours of surgery.¹⁰ The standard outpatient hypoglycemia definition of blood glucose < 70 mg/dL was chosen because the current goal (< 100 mg/dL) was not the standard in previous ADA SOCs that were in place during the study period. Specifically, the 2018 ADA SOC did not provide preoperative recommendations and the 2019-2021 ADA SOC recommended 80 to 180 mg/dL.^10,12-18 For patients who had multiple preoperative blood glucose measurements, the first recorded glucose on the day of the procedure was used.

The secondary outcomes of this study were focused on the preoperative process/care at VHI and postoperative glycemic control. The preoperative process included examining whether medication instructions were given and their quality. Additionally, the number of interventions for hyperglycemia and hypoglycemia were required immediately prior to surgery and the average preoperative HbA_1c (measured within 3 months prior to surgery) were collected and analyzed. For postoperative glycemic control, average blood glucose measurements and number of hypoglycemic (< 70 mg/dL) and hyperglycemic (> 180 mg/dL) events were measured in addition to the frequency of changes made at discharge to patients’ DM medication regimens.

The safety outcome of this study assessed commonly observed postoperative complications and was examined up to 30 days postsurgery. These included acute kidney injury (defined using Kidney Disease: Improving Global Outcomes 2012, the standard during the study period), nonfatal myocardial infarction, nonfatal stroke, and surgical site infections, which were identified from the discharge summary written by the primary surgery service.¹⁹ All-cause mortality also was collected.

Patients were included if they were admitted for major elective surgeries and had a diagnosis of either type 1 or type 2 DM on their problem list, determined by International Classification of Diseases, Tenth Revision codes. Major elective surgery was defined as a procedure that would likely result in a hospital admission of > 24 hours. Of note, patients may have been included in this study more than once if they had > 1 procedure at least 30 days apart and met inclusion criteria within the time frame. Patients were excluded if they were taking no DM medications or chronic steroids (at any dose), residing in a long-term care facility, being managed by a non-VA clinician prior to surgery, or missing a preoperative blood glucose measurement.

All data were collected from the CPRS. A list of surgical cases involving patients with DM who were scheduled to undergo major elective surgeries from January 1, 2018, to December 31, 2021, at VHI was generated. The list was randomized to a smaller number (N = 394) for data collection due to the time and resource constraints for a pharmacy residency project. All data were deidentified and stored in a secured VA server to protect patient confidentiality. Descriptive statistics were used for all results.

Results

Initially, 2362 surgeries were identified. A randomized sample of 394 charts were reviewed and 131 cases met inclusion criteria. Each case involved a unique patient (Figure). The most common reasons for exclusion were 143 patients with diet-controlled DM and 78 nonelective surgeries. The mean (SD) age of patients was 68 (8) years, and the most were male (98.5%) and White (76.3%) (Table 1). 

At baseline, 45 of 131 patients (34.4%) had coronary artery disease and 29 (22.1%) each had autonomic neuropathy and chronic kidney disease. Most surgeries were conducted by orthopedic (32.1%) and peripheral vascular (21.4%) specialties. The mean (SD) length of surgery was 4.6 (2.6) hours and of hospital length of stay was 4 (4) days. No patients stayed longer than the 30-day safety outcome follow-up period. All patients had type 2 DM and took a mean 2 DM medications. The 63 patients taking insulin had a mean (SD) total daily dose of 99 (77) U (Table 2). A preoperative HbA1c was collected in 116 patients within 3 months of surgery, with a mean HbA_1c of 7.0% (range, 5.3-10.7).

No patients had surgeries delayed or canceled because of uncontrolled DM on the day of surgery. The mean preoperative blood glucose level was 146 mg/dL (range, 73-365) (Table 3). No patients had a preoperative blood glucose level of < 70 mg/dL and 19 (14.5%) had a blood glucose level > 180 mg/dL. Among patients with hyperglycemia immediately prior to surgery, 6 (31.6%) had documentation of insulin being provided.

For this sample of patients, the preoperative clinic visit was conducted a mean 22 days prior to the planned surgery date. Among the 131 included patients, 122 (93.1%) had documentation of receiving instructions for DM medications. Among patients who had documented receipt of instructions, only 30 (24.6%) had instructions specifically tailored to their regimen rather than a generic templated form. The mean (SD) preoperative blood glucose was similar for those who received specific perioperative DM instructions at 146 (50) mg/dL when compared with those who did not at 147 (45) mg/dL. The mean (SD) preoperative blood glucose reading for those who had no documentation of receipt of perioperative instructions was 126 (54) mg/dL compared with 147 (46) mg/dL for those who did.

The mean number of postoperative blood glucose events per day was negligible for hypoglycemia and more frequent for hyperglycemia with a mean of 2 events per day. The mean postoperative blood glucose range was 121 to 247 mg/dL with most readings < 180 mg/dL. Upon discharge, most patients continued their home DM regimen with 5 patients (3.8%) having changes made to their regimen upon discharge.

Very few postoperative complications were identified from chart review. The most frequently observed postoperative complications were acute kidney injury, surgical site infections, and nonfatal stroke. There were no documented nonfatal myocardial infarctions. Two patients (1.5%) died within 30 days of the surgery; neither death was deemed to have been related to poor perioperative glycemic control.

Discussion

To our knowledge, this retrospective chart review was the first study to assess preoperative DM management and postoperative complications in a veteran population. VHI is a large, tertiary, level 1a, academic medical center that serves approximately 62,000 veterans annually and performs about 5000 to 6000 surgeries annually, a total that is increasing following the COVID-19 pandemic.²⁰ This study found that the current process of a presurgery clinic visit and day of surgery glucose assessment has prevented surgical delays or cancellations.

Most patients included in this study were well controlled at baseline in accordance with the 2025 ADA SOC HbA_1c recommendation of a preoperative HbA1c of < 8%, which may have contributed to no surgical delays or cancellations.¹⁰ However, not all patients had HbA1c collected within 3 months of surgery or even had one collected at all. Despite the ADA SOC providing no explicit recommendation for universal HbA_1c screening prior to elective procedures, its importance cannot be understated given the body of evidence demonstrating poor outcomes with uncontrolled preoperative DM.^8,10 The glycemic control at baseline may have contributed to the very few postsurgical complications observed in this study.

Although the current process at VHI prevented surgical delays and cancellations in this sample, there are still identified areas for improvement. One area is the instructions the patients received. Patients with DM are often prescribed ≥ 1 medication or a combination of insulins, noninsulin injectables, and oral DM medications, and this study population was no different. Because these medications may influence the anesthesia and perioperative periods, the ADA has specific guidance for altering administration schedules in the days leading up to surgery.¹⁰

Inappropriate administration of DM medications could lead to perioperative hypoglycemia or hyperglycemia, possibly causing surgical delays, case cancellations, and/or postoperative complications.21 Although these data reveal the specificity and documented receipt that the preoperative DM instructions did not impact the first recorded preoperative blood glucose, future studies should examine patient confidence in how to properly administer their DM medications prior to surgery. It is vital that patients receive clear instructions in accordance with the ADA SOC on whether to continue, hold, or adjust the dose of their medications to prevent fluctuations in blood glucose levels in the perioperative period, ensure safety with anesthesia, and prevent postoperative complications such as acute kidney injury. Of note, compliance with guideline recommendations for medication instructions was not examined because the data collection time frame expanded over multiple years and the recommendations have evolved each year as new data emerge.

Preoperative DM Management

The first key takeaway from this study is to ensure patients are ready for surgery with a formal assessment (typically in the form of a clinic visit) prior to the surgery. One private sector health system published their approach to this by administering an automatic preoperative HbA_1c screening for those with a DM diagnosis and all patients with a random plasma glucose ≥ 200 mg/dL.²² Additionally, if the patient's HbA_1c level was not at goal prior to surgery (≥ 8% for those with known DM and ≥ 6.5% with no known DM), patients were referred to endocrinology for further management. Increasing attention to the preoperative visit and extending HbA_1c testing to all patients regardless of DM status also provides an opportunity to identify individuals living with undiagnosed DM.¹

Even though there was no difference in the mean preoperative blood glucose level based on receipt or specificity of preoperative DM instructions, a second takeaway from this study is the importance of ensuring patients receive clear instructions on their DM medication schedule in the perioperative period. A practical first step may be updating the templates used by the primary surgery teams and providing education to the clinicians in the clinic on how to personalize the visits. Because the current preoperative DM process at VHI is managed by the primary surgical team in a clinic visit, there is an opportunity to shift this responsibility to other health care professionals, such as pharmacists—a change shown to reduce unintended omission of home medications following surgery during hospitalization and reduce costs.^23,24

Limitations

This study relied on data included in the patient chart. These data include medication interventions made immediately prior to surgery, which can sometimes be inaccurately charted or difficult to find as they are not documented in the typical medication administration record. Also, the safety outcomes were collected from a discharge summary written by different clinicians, which may lead to information bias. Special attention was taken to ensure these data points were collected as accurately as possible, but it is possible some data may be inaccurate from unintentional human error. Additionally, the safety outcome was limited to a 30-day follow-up, but encompassed the entire length of postoperative stay for all included patients. Finally, given this study was retrospective with no comparison group and the intent was to improve processes at VHI, only hypotheses and potential interventions can be generated from this study. Future prospective studies with larger sample sizes and comparator groups are needed to draw further conclusions.

Conclusions

This study found that the current presurgery process at VHI appears to be successful in preventing surgical delays or cancellations due to hyperglycemia or hypoglycemia. Optimizing DM management can improve surgical outcomes by decreasing rates of postoperative complications, and this study added additional evidence in support of that in a unique population: veterans. Insight on the awareness of preoperative blood glucose management should be gleaned from this study, and based on this sample and site, the preadmission screening process and instructions provided to patients can serve as 2 starting points for optimizing elective surgery.

More than 38 million people in the United States (12%) have diabetes mellitus (DM), though 1 in 5 are unaware they have DM.¹ The prevalence among veterans is even more substantial, impacting nearly 25% of those who received care from the US Department of Veterans Affairs (VA).² DM can lead to increased health care costs in addition to various complications (eg, cardiovascular, renal), especially if left uncontrolled.^1,3 similar impact is found in the perioperative period (defined as at or around the time of an operation), as multiple studies have found that uncontrolled preoperative DM can result in worsened surgical outcomes, including longer hospital stays, more infectious complications, and higher perioperative mortality.^4-6

In contrast, adequate glycemic control assessed with blood glucose levels has been shown to decrease the incidence of postoperative infections.⁷ Optimizing glycemic control during hospital stays, especially postsurgery, has become the standard of care, with most health systems establishing specific protocols. In current literature, most studies examining DM management in the perioperative period are focused on postoperative care, with little attention to the preoperative period.^4,6,7

One study found that patients with poor presurgery glycemic control assessed by hemoglobin A_1c (HbA_1c) levels were more likely to remain hyperglycemic during and after surgery. 8 Blood glucose levels < 200 mg/dL can lead to an increased risk of infection and impaired wound healing, meaning a well-controlled HbA_1c before a procedure serves as a potential factor for success.⁹ The 2025 American Diabetes Association (ADA) Standards of Care (SOC) recommendation is to target HbA_1c < 8% whenever possible, and some health systems require lower levels (eg, < 7% or 7.5%).¹⁰ With that goal in mind and knowing that preoperative hyperglycemia has been shown to be a contributing factor in the delay or cancellation of surgical cases, an argument can be made that attention to preoperative DM management also should be a focus for health care systems performing surgeries.^8,9,11

Attention to glucose control during preoperative care offers an opportunity to screen for DM in patients who may not have been screened otherwise and to standardize perioperative DM management. Since DM disproportionately impacts veterans, this is a pertinent issue to the VA. Veterans can be more susceptible to complications if DM is left uncontrolled prior to surgery. To determine readiness for surgery and control of comorbid conditions such as DM before a planned surgery, facilities often perform a preoperative clinic assessment, often in a multidisciplinary clinic.

At Veteran Health Indiana (VHI), a presurgery clinic visit involving the primary surgery service (physician, nurse practitioner, and/or a physician assistant) is conducted 1 to 2 months prior to the planned procedure to determine whether a patient is ready for surgery. During this visit, patients receive a packet with instructions for various tasks and medications, such as applying topical antibiotic prophylaxis on the anticipated surgical site. This is documented in the form of a note in the VHI Computerized Patient Record System (CPRS). The medication instructions are provided according to the preferences of the surgical team. These may be templated notes that contain general directions on the timing and dosing of specific medications, in addition to instructions for holding or reducing doses when appropriate. The instructions can be tailored by the team conducting the preoperative visit (eg, “Take 20 units of insulin glargine the day before surgery” vs “Take half of your long-acting insulin the night before surgery”). Specific to DM, VHI has a nurse-driven day of surgery glucose assessment where point-of-care blood glucose is collected during preoperative holding for most patients.

There is limited research assessing the level of preoperative glycemic control and the incidence of complications in a veteran population. The objective of this study was to gain a baseline understanding of what, if any, standardization exists for preoperative instructions for DM medications and to assess the level of preoperative glycemic control and postoperative complications in patients with DM undergoing major elective surgical procedures.

Methods

This retrospective, single-center chart review was conducted at VHI. The Indiana University and VHI institutional review boards determined that this quality improvement project was exempt from review.

The primary outcome was the number of patients with surgical procedures delayed or canceled due to hyperglycemia or hypoglycemia. Hyperglycemia was defined as blood glucose > 180 mg/dL and hypoglycemia was defined as < 70 mg/dL, slight variations from the current ADA SOC preoperative specific recommendation of a blood glucose reading of 100 to 180 mg/dL within 4 hours of surgery.¹⁰ The standard outpatient hypoglycemia definition of blood glucose < 70 mg/dL was chosen because the current goal (< 100 mg/dL) was not the standard in previous ADA SOCs that were in place during the study period. Specifically, the 2018 ADA SOC did not provide preoperative recommendations and the 2019-2021 ADA SOC recommended 80 to 180 mg/dL.^10,12-18 For patients who had multiple preoperative blood glucose measurements, the first recorded glucose on the day of the procedure was used.

The secondary outcomes of this study were focused on the preoperative process/care at VHI and postoperative glycemic control. The preoperative process included examining whether medication instructions were given and their quality. Additionally, the number of interventions for hyperglycemia and hypoglycemia were required immediately prior to surgery and the average preoperative HbA_1c (measured within 3 months prior to surgery) were collected and analyzed. For postoperative glycemic control, average blood glucose measurements and number of hypoglycemic (< 70 mg/dL) and hyperglycemic (> 180 mg/dL) events were measured in addition to the frequency of changes made at discharge to patients’ DM medication regimens.

These included acute kidney injury (defined using Kidney Disease: Improving Global Outcomes 2012, the standard during the study period), nonfatal myocardial infarction, nonfatal stroke, and surgical site infections, which were identified from the discharge summary written by the primary surgery service.¹⁹ All-cause mortality also was collected.

Patients were included if they were admitted for major elective surgeries and had a diagnosis of either type 1 or type 2 DM on their problem list, determined by International Classification of Diseases, Tenth Revision codes. Major elective surgery was defined as a procedure that would likely result in a hospital admission of > 24 hours. Of note, patients may have been included in this study more than once if they had > 1 procedure at least 30 days apart and met inclusion criteria within the time frame. Patients were excluded if they were taking no DM medications or chronic steroids (at any dose), residing in a long-term care facility, being managed by a non-VA clinician prior to surgery, or missing a preoperative blood glucose measurement.

All data were collected from the CPRS. A list of surgical cases involving patients with DM who were scheduled to undergo major elective surgeries from January 1, 2018, to December 31, 2021, at VHI was generated. The list was randomized to a smaller number (N = 394) for data collection due to the time and resource constraints for a pharmacy residency project. All data were deidentified and stored in a secured VA server to protect patient confidentiality. Descriptive statistics were used for all results.

Results

Initially, 2362 surgeries were identified. A randomized sample of 394 charts were reviewed and 131 cases met inclusion criteria. Each case involved a unique patient (Figure). The most common reasons for exclusion were 143 patients with diet-controlled DM and 78 nonelective surgeries. The mean (SD) age of patients was 68 (8) years, and the most were male (98.5%) and White (76.3%) (Table 1). 

At baseline, 45 of 131 patients (34.4%) had coronary artery disease and 29 (22.1%) each had autonomic neuropathy and chronic kidney disease. Most surgeries were conducted by orthopedic (32.1%) and peripheral vascular (21.4%) specialties. The mean (SD) length of surgery was 4.6 (2.6) hours and of hospital length of stay was 4 (4) days. No patients stayed longer than the 30-day safety outcome follow-up period. All patients had type 2 DM and took a mean 2 DM medications. The 63 patients taking insulin had a mean (SD) total daily dose of 99 (77) U (Table 2). A preoperative HbA1c was collected in 116 patients within 3 months of surgery, with a mean HbA_1c of 7.0% (range, 5.3-10.7).

No patients had surgeries delayed or canceled because of uncontrolled DM on the day of surgery. The mean preoperative blood glucose level was 146 mg/dL (range, 73-365) (Table 3). No patients had a preoperative blood glucose level of < 70 mg/dL and 19 (14.5%) had a blood glucose level > 180 mg/dL. Among patients with hyperglycemia immediately prior to surgery, 6 (31.6%) had documentation of insulin being provided.

For this sample of patients, the preoperative clinic visit was conducted a mean 22 days prior to the planned surgery date. Among the 131 included patients, 122 (93.1%) had documentation of receiving instructions for DM medications. Among patients who had documented receipt of instructions, only 30 (24.6%) had instructions specifically tailored to their regimen rather than a generic templated form. The mean (SD) preoperative blood glucose was similar for those who received specific perioperative DM instructions at 146 (50) mg/dL when compared with those who did not at 147 (45) mg/dL. The mean (SD) preoperative blood glucose reading for those who had no documentation of receipt of perioperative instructions was 126 (54) mg/dL compared with 147 (46) mg/dL for those who did.

The mean number of postoperative blood glucose events per day was negligible for hypoglycemia and more frequent for hyperglycemia with a mean of 2 events per day. The mean postoperative blood glucose range was 121 to 247 mg/dL with most readings < 180 mg/dL. Upon discharge, most patients continued their home DM regimen with 5 patients (3.8%) having changes made to their regimen upon discharge.

Very few postoperative complications were identified from chart review. The most frequently observed postoperative complications were acute kidney injury, surgical site infections, and nonfatal stroke. There were no documented nonfatal myocardial infarctions. Two patients (1.5%) died within 30 days of the surgery; neither death was deemed to have been related to poor perioperative glycemic control.

Discussion

To our knowledge, this retrospective chart review was the first study to assess preoperative DM management and postoperative complications in a veteran population. VHI is a large, tertiary, level 1a, academic medical center that serves approximately 62,000 veterans annually and performs about 5000 to 6000 surgeries annually, a total that is increasing following the COVID-19 pandemic.²⁰ This study found that the current process of a presurgery clinic visit and day of surgery glucose assessment has prevented surgical delays or cancellations.

Most patients included in this study were well controlled at baseline in accordance with the 2025 ADA SOC HbA_1c recommendation of a preoperative HbA1c of < 8%, which may have contributed to no surgical delays or cancellations.¹⁰ However, not all patients had HbA1c collected within 3 months of surgery or even had one collected at all. Despite the ADA SOC providing no explicit recommendation for universal HbA_1c screening prior to elective procedures, its importance cannot be understated given the body of evidence demonstrating poor outcomes with uncontrolled preoperative DM.^8,10 The glycemic control at baseline may have contributed to the very few postsurgical complications observed in this study.

Although the current process at VHI prevented surgical delays and cancellations in this sample, there are still identified areas for improvement. One area is the instructions the patients received. Patients with DM are often prescribed ≥ 1 medication or a combination of insulins, noninsulin injectables, and oral DM medications, and this study population was no different. Because these medications may influence the anesthesia and perioperative periods, the ADA has specific guidance for altering administration schedules in the days leading up to surgery.¹⁰

Inappropriate administration of DM medications could lead to perioperative hypoglycemia or hyperglycemia, possibly causing surgical delays, case cancellations, and/or postoperative complications.21 Although these data reveal the specificity and documented receipt that the preoperative DM instructions did not impact the first recorded preoperative blood glucose, future studies should examine patient confidence in how to properly administer their DM medications prior to surgery. It is vital that patients receive clear instructions in accordance with the ADA SOC on whether to continue, hold, or adjust the dose of their medications to prevent fluctuations in blood glucose levels in the perioperative period, ensure safety with anesthesia, and prevent postoperative complications such as acute kidney injury. Of note, compliance with guideline recommendations for medication instructions was not examined because the data collection time frame expanded over multiple years and the recommendations have evolved each year as new data emerge.

Preoperative DM Management

The first key takeaway from this study is to ensure patients are ready for surgery with a formal assessment (typically in the form of a clinic visit) prior to the surgery. One private sector health system published their approach to this by administering an automatic preoperative HbA_1c screening for those with a DM diagnosis and all patients with a random plasma glucose ≥ 200 mg/dL.²² Additionally, if the patient's HbA_1c level was not at goal prior to surgery (≥ 8% for those with known DM and ≥ 6.5% with no known DM), patients were referred to endocrinology for further management. Increasing attention to the preoperative visit and extending HbA_1c testing to all patients regardless of DM status also provides an opportunity to identify individuals living with undiagnosed DM.¹

Even though there was no difference in the mean preoperative blood glucose level based on receipt or specificity of preoperative DM instructions, a second takeaway from this study is the importance of ensuring patients receive clear instructions on their DM medication schedule in the perioperative period. A practical first step may be updating the templates used by the primary surgery teams and providing education to the clinicians in the clinic on how to personalize the visits. Because the current preoperative DM process at VHI is managed by the primary surgical team in a clinic visit, there is an opportunity to shift this responsibility to other health care professionals, such as pharmacists—a change shown to reduce unintended omission of home medications following surgery during hospitalization and reduce costs.^23,24

Limitations

This study relied on data included in the patient chart. These data include medication interventions made immediately prior to surgery, which can sometimes be inaccurately charted or difficult to find as they are not documented in the typical medication administration record. Also, the safety outcomes were collected from a discharge summary written by different clinicians, which may lead to information bias. Special attention was taken to ensure these data points were collected as accurately as possible, but it is possible some data may be inaccurate from unintentional human error. Additionally, the safety outcome was limited to a 30-day follow-up, but encompassed the entire length of postoperative stay for all included patients. Finally, given this study was retrospective with no comparison group and the intent was to improve processes at VHI, only hypotheses and potential interventions can be generated from this study. Future prospective studies with larger sample sizes and comparator groups are needed to draw further conclusions.

Conclusions

This study found that the current presurgery process at VHI appears to be successful in preventing surgical delays or cancellations due to hyperglycemia or hypoglycemia. Optimizing DM management can improve surgical outcomes by decreasing rates of postoperative complications, and this study added additional evidence in support of that in a unique population: veterans. Insight on the awareness of preoperative blood glucose management should be gleaned from this study, and based on this sample and site, the preadmission screening process and instructions provided to patients can serve as 2 starting points for optimizing elective surgery.

Type 2 diabetes mellitus (T2DM) is a chronic disease becoming more prevalent each year and is the seventh-leading cause of death in the United States.¹ The most common reason for hospitalization for patients with T2DM is uncontrolled glycemic levels.² Nearly 25% of the US Department of Veterans Affairs (VA) patient population has T2DM.³ T2DM is the leading cause of blindness, end-stage renal disease, and amputation for VA patients.⁴

According to the 2023 American Diabetes Association (ADA) guidelines, treatment goals of T2DM include eliminating symptoms, preventing or delaying complications, and attaining glycemic goals. A typical hemoglobin A_1c (HbA_1c) goal range is < 7%, but individual goals can vary up to < 9% due to a multitude of factors, including patient comorbidities and clinical status.⁵

Initial treatment recommendations are nonpharmacologic and include comprehensive lifestyle interventions such as optimizing nutrition, physical activity, and behavioral therapy. When pharmacologic therapy is required, metformin is the preferred first-line treatment for the majority of newly diagnosed patients with T2DM and should be added to continued lifestyle management.⁵ If HbA_1c levels remains above goal, the 2023 ADA guidelines recommend adding a second medication, including but not limited to insulin, a glucagonlike peptide-1 receptor agonist (GLP-1RA), or a sodium-glucose cotransporter 2 inhibitor. Medication choice is largely based on the patient’s concomitant conditions (eg, atherosclerotic cardiovascular disease, heart failure, or chronic kidney disease). The 2023 ADA guidelines suggest initiating insulin therapy when a patient's blood glucose ≥ 300 mg/dL, HbA_1c > 10%, or if the patient has symptoms of hyperglycemia, even at initial diagnosis. Initiating medications to minimize or avoid hypoglycemia is a priority, especially in high-risk individuals.⁵

Clinical evidence shows that GLP-1RAs may provide similar glycemic control to insulin with lower risk of hypoglycemia.⁶ Other reported benefits of GLP-1RAs include weight loss, blood pressure reduction, and improved lipid levels. The most common adverse events (AEs) with GLP-1RAs are gastrointestinal. Including GLP-1RAs in T2DM pharmacotherapy may lower the risk of hypoglycemia, especially in patients at high risk of hypoglycemia.

The 2023 ADA guidelines indicate that it is appropriate to initiate GLP-]1RAs in patients on insulin.⁵ However, while GLP-1RAs do not increase the risk of hypoglycemia independently, combination treatment with GLP-1RAs and insulin can still result in hypoglycemia.⁶ Insulin is the key suspect of this hypoglycemic risk.⁷ Thus, if insulin dosage can be reduced or discontinued, this might reduce the risk of hypoglycemia.

The literature is limited on how the addition of a GLP-1RA to insulin treatment will affect the patient's daily insulin doses, particularly for the veteran population. The goal of this study is to examine this gap in current research by examining semaglutide, which is the current formulary preferred GLP-1RA at the VA.

Semaglutide is subcutaneously initiated at a dose of 0.25 mg once weekly for 4 weeks to reduce gastrointestinal symptoms, then increased to 0.5 mg weekly. Additional increases to a maintenance dose of 1 mg or 2 mg weekly can occur to achieve glycemic goals. The SUSTAIN-FORTE randomized controlled trial sought to determine whether there was a difference in HbA_1c level reduction and significant weight loss with the 2-mg vs 1-mg dose.⁸ Patients in the trial were taking metformin but needed additional medication to control their HbA_1c. They were not using insulin and may or may not have been taking sulfonylureas prior to semaglutide initiation. Semaglutide 2 mg was found to significantly improve HbA_1c control and promote weight loss compared with semaglutide 1 mg, while maintaining a similar safety profile.

Because this study involved patients who required additional HbA_1c control, although semaglutide reduced HbA_1c, not all patients were able to reduce their other diabetes medications, which depended on the baseline HbA_1c level and the level upon completion of semaglutide titration. Dose reductions for the patients’ other T2DM medications were not reported at trial end. SUSTAIN-FORTE established titration up to semaglutide 2 mg as effective for HbA_1c reduction, although it did not study patients also on insulin.⁸

Insulin is associated with hypoglycemic risk, weight gain, and other AEs.^7,8 This study analyzed whether increasing semaglutide could reduce insulin doses and therefore reduce risk of AEs in patients with T2DM.

Methods

A retrospective, single-center, chart review was conducted at VA Sioux Falls Health Care System (VASFHCS). Data were collected through manual review of VASFHCS electronic medical records. Patients aged ≥ 18 years with active prescriptions for at least once-daily insulin who were initiated on 2-mg weekly dose of semaglutide at the VASFHCS clinical pharmacy practitioner medication management clinic between January 1, 2021, and September 1, 2023, were included. VASFHCS clinical pharmacy practitioners have a scope of practice that allows them to initiate, modify, or discontinue medication therapy within medication management clinics.

The most frequently used prandial insulin at VASFHCS is insulin aspart, and the most frequently used basal insulin is insulin glargine. Patients were retrospectively monitored as they progressed from baseline (the point in time where semaglutide 0.5 mg was initiated) to ≥ 3 months on semaglutide 2-mg therapy. Patients were excluded if they previously used a GLP-1RA or if they were on sliding scale insulin without an exact daily dosage.

The primary endpoint was the percent change in total daily insulin dose from baseline to each dose increase after receiving semaglutide 2 mg for ≥ 3 months. Secondary endpoints included changes in daily prandial insulin dose, daily basal insulin dose, HbA_1c, and number of hypoglycemic events reported. Data collected included age, race, weight, body mass index, total daily prandial insulin dose, total daily basal insulin dose, HbA_1c, and hypoglycemic events reported at the visit when semaglutide was initiated.

Statistical Analysis

The sample size was calculated prior to data collection, and it was determined that for α = .05, 47 patients were needed to achieve 95% power. The primary endpoint was assessed using a paired t test, as were each secondary endpoint. Results with P < .05 were considered statistically significant.

Results

Sixty-two patients were included. The mean HbA_1c level at baseline was 7.7%, the baseline mean prandial and insulin daily doses were 41.5 units and 85.1 units, respectively (Table 1) From baseline to initiation of a semaglutide 1-mg dose, the daily insulin dose changed –5.6% (95% CI, 2.2-14.0; P = .008). From baseline to 2-mg dose initiation daily insulin changed -22.2% (95% CI, 22.0-35.1; P < .001) and for patients receiving semaglutide 2 mg for ≥ 3 months it changed -36.9% (95% CI, 37.4-56.5; P < .001) (Figure).

After receiving the 2-mg dose for ≥ 3 months, the mean daily dose of prandial insulin decreased from 41.5 units to 24.6 units (95% CI, 12.6-21.2; P < .001); mean daily dose of basal insulin decreased from 85.1 units to 52.1 units (95% CI, 23.9-42.0; P < .001); and mean HbA_1c level decreased from 7.7% to 7.1% (95% CI, 0.3-0.8; P < .001). Mean number of hypoglycemic events reported was not statistically significant, changing from 3.6 to 3.2 (95% CI, –0.6 to 0.1; P = .21) (Table 2).

Discussion

This study investigated the effect of subcutaneous semaglutide dose escalation on total daily insulin dose for patients with T2DM. There was a statistically significant decrease in total daily insulin dose from baseline to 1 mg initiation; this decrease continued with further insulin dose reduction seen at the 2-mg dose initiation and additional insulin dose reduction at ≥ 3 months at this dose. It was hypothesized there would be a significant total daily insulin dose reduction at some point, especially when transitioning from the semaglutide 1-mg to the 2-mg dose, based on previous research. ^9,10 The additional reduction in daily insulin dose when continuing on semaglutide 2 mg for ≥ 3 months was an unanticipated but added benefit, showing that if tolerated, maintaining the 2-mg dose will help patients reduce their insulin doses.

In terms of secondary endpoints, there was a statistically significant decrease in mean total daily dose individually for prandial and basal insulin from baseline to ≥ 3 months after semaglutide 2 mg initiation. The change in HbA_1c level was also statistically significant and decreased from baseline, even as insulin doses were reduced. This change in HbA_1c level was expected; previous literature has shown a significant link between improving HbA_1c control when semaglutide doses are increased to 2 mg weekly.¹⁰ Due to having been shown in previous trials, it was expected that HbA_1c levels would decrease even when the insulin doses were being reduced.¹⁰ Insulin dose reduction can potentially be added to the growing evidence of semaglutide benefits. The change in the number of hypoglycemic events was not statistically significant, which was unexpected since previous research show a trend in patients taking GLP-1RAs having fewer hypoglycemic events than those taking insulin.⁶ Further investigation with a larger sample size and prospective trial could determine whether this result is an outlier. In this study, there was no increase in HbA_1c or hypoglycemic events reported with increasing semaglutide doses, which provides further evidence of the safety of semaglutide even at higher doses.

These data suggest that for a patient with T2DM who is already taking insulin, the recommended titration of semaglutide is to start with 0.5 mg and titrate up to a 2-mg subcutaneous weekly dose and to then continue at that dose. As long as the 2-mg dose is tolerated, it will provide patients with the most HbA_1c control and lead to a reduction of their total daily insulin doses according to these results.

Strengths and Limitations

This study compared patient data at different points. This method did not require a second distinct control group, which would potentially introduce confounding factors, such as different baseline characteristics. Another strength is that documentation was available for all patients throughout the study so no one was lost to follow-up. This allowed comprehensive data collection and provided a stronger conclusion given the completeness of the data from baseline to follow-up.

Limitations include the retrospective design and small sample size. In addition, the study design did not allow for randomization. There is no documentation of adherence to medication regimen, which was difficult to determine due to the retrospective nature. Other changes to the patients’ medication regimen were not collected in aggregate and thus, it is possible the total daily insulin dose was impacted by other medication changes. There is also potential for inconsistent documentation of the patients’ true total daily insulin dose in the medical record, thus leading to inaccuracy of recorded data.

Conclusions

A small sample of veterans with T2DM had statistically significant reductions in total daily insulin dose when subcutaneous semaglutide was initiated, as well as after each dose increase. There was also a statistically significant reduction in HbA_1c levels from baseline even as patient insulin doses were reduced. These results support the current practice of using semaglutide to treat T2DM, suggesting it may be safe and effective at reducing HbA_1c levels as the dose is titrated up to 2 mg. There was no statistically significant change in the number of hypoglycemic events reported as semaglutide was titrated up. Thus, when semaglutide is increased to the maximum recommended dose of 2 mg for T2DM, patients may experience a reduction of their total daily dose of insulin and HbA_1c levels. These benefits may reduce the risk of insulin-related AEs while maintaining appropriate glycemic control.

The SUSTAIN-FORTE randomized controlled trial sought to determine whether there was a difference in HbA_1c level reduction and significant weight loss with the 2-mg vs 1-mg dose.⁸ Patients in the trial were taking metformin but needed additional medication to control their HbA_1c. They were not using insulin and may or may not have been taking sulfonylureas prior to semaglutide initiation. Semaglutide 2 mg was found to significantly improve HbA_1c control and promote weight loss compared with semaglutide 1 mg, while maintaining a similar safety profile.

Because this study involved patients who required additional HbA_1c control, although semaglutide reduced HbA_1c, not all patients were able to reduce their other diabetes medications, which depended on the baseline HbA_1c level and the level upon completion of semaglutide titration. Dose reductions for the patients’ other T2DM medications were not reported at trial end. SUSTAIN-FORTE established titration up to semaglutide 2 mg as effective for HbA_1c reduction, although it did not study patients also on insulin.⁸

Insulin is associated with hypoglycemic risk, weight gain, and other AEs.^7,8 This study analyzed whether increasing semaglutide could reduce insulin doses and therefore reduce risk of AEs in patients with T2DM.

Methods

A retrospective, single-center, chart review was conducted at VA Sioux Falls Health Care System (VASFHCS). Data were collected through manual review of VASFHCS electronic medical records. Patients aged ≥ 18 years with active prescriptions for at least once-daily insulin who were initiated on 2-mg weekly dose of semaglutide at the VASFHCS clinical pharmacy practitioner medication management clinic between January 1, 2021, and September 1, 2023, were included. VASFHCS clinical pharmacy practitioners have a scope of practice that allows them to initiate, modify, or discontinue medication therapy within medication management clinics.

The most frequently used prandial insulin at VASFHCS is insulin aspart, and the most frequently used basal insulin is insulin glargine. Patients were retrospectively monitored as they progressed from baseline (the point in time where semaglutide 0.5 mg was initiated) to ≥ 3 months on semaglutide 2-mg therapy. Patients were excluded if they previously used a GLP-1RA or if they were on sliding scale insulin without an exact daily dosage.

The primary endpoint was the percent change in total daily insulin dose from baseline to each dose increase after receiving semaglutide 2 mg for ≥ 3 months. Secondary endpoints included changes in daily prandial insulin dose, daily basal insulin dose, HbA_1c, and number of hypoglycemic events reported. Data collected included age, race, weight, body mass index, total daily prandial insulin dose, total daily basal insulin dose, HbA_1c, and hypoglycemic events reported at the visit when semaglutide was initiated.

Statistical Analysis

The sample size was calculated prior to data collection, and it was determined that for α = .05, 47 patients were needed to achieve 95% power. The primary endpoint was assessed using a paired t test, as were each secondary endpoint. Results with P < .05 were considered statistically significant.

Results

Sixty-two patients were included. The mean HbA_1c level at baseline was 7.7%, the baseline mean prandial and insulin daily doses were 41.5 units and 85.1 units, respectively (Table 1) From baseline to initiation of a semaglutide 1-mg dose, the daily insulin dose changed –5.6% (95% CI, 2.2-14.0; P = .008). From baseline to 2-mg dose initiation daily insulin changed -22.2% (95% CI, 22.0-35.1; P < .001) and for patients receiving semaglutide 2 mg for ≥ 3 months it changed -36.9% (95% CI, 37.4-56.5; P < .001) (Figure).

After receiving the 2-mg dose for ≥ 3 months, the mean daily dose of prandial insulin decreased from 41.5 units to 24.6 units (95% CI, 12.6-21.2; P < .001); mean daily dose of basal insulin decreased from 85.1 units to 52.1 units (95% CI, 23.9-42.0; P < .001); and mean HbA_1c level decreased from 7.7% to 7.1% (95% CI, 0.3-0.8; P < .001). Mean number of hypoglycemic events reported was not statistically significant, changing from 3.6 to 3.2 (95% CI, –0.6 to 0.1; P = .21) (Table 2).

Discussion

This study investigated the effect of subcutaneous semaglutide dose escalation on total daily insulin dose for patients with T2DM. There was a statistically significant decrease in total daily insulin dose from baseline to 1 mg initiation; this decrease continued with further insulin dose reduction seen at the 2-mg dose initiation and additional insulin dose reduction at ≥ 3 months at this dose. It was hypothesized there would be a significant total daily insulin dose reduction at some point, especially when transitioning from the semaglutide 1-mg to the 2-mg dose, based on previous research. ^9,10 The additional reduction in daily insulin dose when continuing on semaglutide 2 mg for ≥ 3 months was an unanticipated but added benefit, showing that if tolerated, maintaining the 2-mg dose will help patients reduce their insulin doses.

In terms of secondary endpoints, there was a statistically significant decrease in mean total daily dose individually for prandial and basal insulin from baseline to ≥ 3 months after semaglutide 2 mg initiation. The change in HbA_1c level was also statistically significant and decreased from baseline, even as insulin doses were reduced. This change in HbA_1c level was expected; previous literature has shown a significant link between improving HbA_1c control when semaglutide doses are increased to 2 mg weekly.¹⁰ Due to having been shown in previous trials, it was expected that HbA_1c levels would decrease even when the insulin doses were being reduced.¹⁰ Insulin dose reduction can potentially be added to the growing evidence of semaglutide benefits. The change in the number of hypoglycemic events was not statistically significant, which was unexpected since previous research show a trend in patients taking GLP-1RAs having fewer hypoglycemic events than those taking insulin.⁶ Further investigation with a larger sample size and prospective trial could determine whether this result is an outlier. In this study, there was no increase in HbA_1c or hypoglycemic events reported with increasing semaglutide doses, which provides further evidence of the safety of semaglutide even at higher doses.

These data suggest that for a patient with T2DM who is already taking insulin, the recommended titration of semaglutide is to start with 0.5 mg and titrate up to a 2-mg subcutaneous weekly dose and to then continue at that dose. As long as the 2-mg dose is tolerated, it will provide patients with the most HbA_1c control and lead to a reduction of their total daily insulin doses according to these results.

Strengths and Limitations

This study compared patient data at different points. This method did not require a second distinct control group, which would potentially introduce confounding factors, such as different baseline characteristics. Another strength is that documentation was available for all patients throughout the study so no one was lost to follow-up. This allowed comprehensive data collection and provided a stronger conclusion given the completeness of the data from baseline to follow-up.

Limitations include the retrospective design and small sample size. In addition, the study design did not allow for randomization. There is no documentation of adherence to medication regimen, which was difficult to determine due to the retrospective nature. Other changes to the patients’ medication regimen were not collected in aggregate and thus, it is possible the total daily insulin dose was impacted by other medication changes. There is also potential for inconsistent documentation of the patients’ true total daily insulin dose in the medical record, thus leading to inaccuracy of recorded data.

Conclusions

A small sample of veterans with T2DM had statistically significant reductions in total daily insulin dose when subcutaneous semaglutide was initiated, as well as after each dose increase. There was also a statistically significant reduction in HbA_1c levels from baseline even as patient insulin doses were reduced. These results support the current practice of using semaglutide to treat T2DM, suggesting it may be safe and effective at reducing HbA_1c levels as the dose is titrated up to 2 mg. There was no statistically significant change in the number of hypoglycemic events reported as semaglutide was titrated up. Thus, when semaglutide is increased to the maximum recommended dose of 2 mg for T2DM, patients may experience a reduction of their total daily dose of insulin and HbA_1c levels. These benefits may reduce the risk of insulin-related AEs while maintaining appropriate glycemic control.
