Racial and Ethnic Variation in Complementary and Integrative Health Therapy Use Among US Veterans

White individuals are the greatest users of complementary and integrative health (CIH) therapies in the general population, but this might partially be due to differences in age, health condition, and location. Identifying the nuances in racial and ethnic differences in care is one important step to addressing them. To evaluate racial and ethnic differences in Veterans Affairs (VA)-covered CIH therapy use in a more nuanced manner by examining the association of 5 demographic characteristics, health conditions, and medical facility locations with those differences. Retrospective cross-sectional observational study of VA health care system users, using electronic health record and administrative data at all VA medical facilities and community-based clinics. Participants included veterans with nonmissing race and ethnicity data using VA-funded health care between October 2018 and September 2019. Data were analyzed from June 2022 to April 2023. Any use of VA-covered acupuncture, chiropractic care, massage therapy, yoga, or meditation/mindfulness. The sample consisted of 5 260 807 veterans with a mean (SD) age of 62.3 (16.4) years and was 91% male (4 788 267 veterans), 67% non-Hispanic White (3 547 140 veterans), 6% Hispanic (328 396 veterans), and 17% Black (903 699 veterans). Chiropractic care was the most used CIH therapy among non-Hispanic White veterans, Hispanic veterans, and veterans of other races and ethnicities, while acupuncture was the most commonly used therapy among Black veterans. When not accounting for the location of the VA medical facilities in which veterans used health care, Black veterans appeared more likely to use yoga and meditation than non-Hispanic White veterans and far less likely to use chiropractic care, while those of Hispanic or other race and ethnicity appeared more likely to use massage than non-Hispanic White veterans. However, those differences mostly disappeared once controlling for medical facility location, with few exceptions-after adjustment Black veterans were less likely than non-Hispanic White veterans to use yoga and more likely to use chiropractic care. This large-scale, cross-sectional study found racial and ethnic differences in use of 4 of 5 CIH therapies among VA health care system users when not considering their medical facility location. Given those differences mostly disappeared once medical facilities were accounted for, the results demonstrated the importance of considering facilities and residential locations when examining racial differences in CIH therapy use. Medical facilities could be a proxy for the racial and ethnic composition of their patients, CIH therapy availability, regional patient or clinician attitudes, or therapy availability.

Temporal variation in individual social risk factors associated with testing positive for SARS-CoV-2 among veterans in the veterans health administration

PurposeMarginalized communities have been disproportionally impacted by SARS-CoV-2. How the associations between social determinants of health and the risk of SARS-CoV-2 infection shifted across time is unknown. In this evaluation, we examine individual-level social determinants of health as social risk factors for SARS-CoV-2 infection across the first 12 months of the pandemic among US Veterans.MethodsWe conducted a retrospective cohort analysis of 946,358 Veterans who sought testing or treatment for SARS-CoV-2 infection in U.S. Department of Veterans Affairs medical facilities. We estimated risk ratios for testing positive by social risk factors, adjusting for demographics, comorbidities, and time. Adjusted models were stratified by pandemic phase to assess temporal fluctuations in social risks.ResultsApproximately 19% of Veterans tested positive for SARS-CoV-2. Larger household size was a persistent risk factor and this association increased over time. Early in the pandemic, lower county-level population density was associated with lower SARS-CoV-2 infection risk, but between June 1 and August 31, 2020, this trend reversed.ConclusionsTemporal fluctuations in social risks associated with Veterans’ SARS-CoV-2 infection suggest the need for ongoing, real-time tracking as the social and medical environment continues to evolve.

Vaccinating Veterans for COVID-19 at the U.S. Department of Veterans Affairs

IntroductionWith the COVID-19 (most recent) Omicron variant surge across the U.S., more research is needed to better understand how vaccination and booster uptake can be increased. COVID-19 vaccinations have proven to help decrease the likelihood of becoming seriously ill, getting hospitalized, or dying. Studies examining patient characteristics of individuals who received COVID-19 vaccinations are limited. This study examines the patient characteristics of veterans who were vaccinated during the first 8 months (December 2020–July 2021) of the vaccination rollout at the U.S. Department of Veterans Affairs.MethodsUsing the U.S. Department of Veterans Affairs administrative and clinical data, bivariate and multivariate analyses were conducted to determine sociodemographic and health factors associated with the likelihood of receiving COVID-19 vaccination at the U.S. Department of Veterans Affairs.ResultsThe analytic sample included 5,914,741 U.S. Department of Veterans Affairs users (49.7% vaccinated). Among the U.S. Department of Veterans Affairs medical facilities nationwide, COVID-19 vaccination rates (≥1 dose) varied from 33.9% to 73.7%. Veterans who were non-Hispanic American Indian/Alaskan natives, younger, living in rural areas, male, and unmarried; had U.S. Department of Veterans Affairs health insurance only; had fewer chronic conditions; did not receive the seasonal influenza vaccine; and were not living in community living centers or nursing homes were less likely to get vaccinated.ConclusionsUnderstanding which groups of veterans are less likely to be vaccinated allows the U.S. Department of Veterans Affairs to develop targeted interventions to improve uptake in these groups. These results can also guide non–U.S. Department of Veterans Affairs organizations to create evidence-based educational outreach programs that reduce vaccine hesitancy among veterans who do not use U.S. Department of Veterans Affairs.

Geographic and temporal variation in racial and ethnic disparities in SARS-CoV-2 positivity between February 2020 and August 2021 in the United States

The coronavirus pandemic has disproportionally impacted racial and ethnic minority communities in the United States. Patterns of these disparities may be changing over time as outbreaks occur in different communities. Utilizing electronic health record data from the US Department of Veterans Affairs (VA), we estimated odds ratios, stratified by time period and region, for testing positive among 1,313,402 individuals tested for SARS-CoV-2 between February 12, 2020 and August 16, 2021 at VA medical facilities. We adjusted for personal characteristics (sex, age, rural/urban residence, VA facility) and a wide range of clinical characteristics that have been evaluated in prior SARS-CoV-2 reports and could potentially explain racial/ethnic disparities in SARS-CoV-2. Our study found racial and ethnic disparities for testing positive were most pronounced at the beginning of the pandemic and decreased over time. A key finding was that the disparity among Hispanic individuals attenuated but remained elevated, while disparities among Asian individuals reversed by March 1, 2021. The variation in racial and ethnic disparities in SARS-CoV-2 positivity by time and region, independent of underlying health status and other demographic characteristics in a nationwide cohort, provides important insight for strategies to prevent further outbreaks.

Household Preparedness and Perceptions of Workforce Preparedness During Pandemics: A Health Care Employee Survey at the US Department of Veterans Affairs.

To examine the effects of household preparedness on perceptions of workplace preparedness during a pandemic among all employees at the US Department of Veterans Affairs (VA) medical facilities. The VA Preparedness Survey (October-December 2018, Los Angeles, CA) used a stratified simple random, web-based survey. Multivariate statistical analyses examined the effect of household preparedness on perceptions of workforce preparedness during a pandemic: institutional readiness; desire for additional training; and understanding their role and its importance. VA employees totaling 4026 participated. For a pandemic, 55% were confident in their VA medical facility's ability to respond, 63% would like additional training, 49% understood their role during a response, and 68% reported their role as important. Only 23% reported being "well prepared" at home during major disasters. After controlling for study-relevant factors, household preparedness was positively associated with perceptions of workforce preparedness during a pandemic. Efforts to increase household preparedness for health care employees could bolster workforce preparedness during pandemics. Organizations should consider robust policies and strategies, such as flexible work arrangements, in order to mitigate factors that may serve as barriers to household preparedness.

Determinants of Workforce Preparedness during Pandemics Among Healthcare Workers at the U.S. Department of Veterans Affairs.

Objective:An infectious disease outbreak can place a significant burden on healthcare systems, however, our understanding of the broader healthcare workforce’s preparedness during a pandemic is limited. This study examines factors that influence perceived workforce preparedness at the U.S. Department of Veterans Affairs (VA) during a pandemic.Methods:The VA Preparedness Survey was a random, anonymous, web-based survey fielded nationwide October to December 2018. Multivariate statistical analyses examined the effects of study relevant factors (sociodemographic, work-related, general health, and household-related characteristics of VA employees) on perceptions of workforce preparedness, including institutional readiness and understanding of individual roles during a pandemic.Results:Four thousand and twenty-six VA employees responded. Overall, 55% were confident in their VA medical facility’s ability to respond; 49% understood their role; and 68% reported their role to be important during a pandemic. After controlling for study-relevant factors, household preparedness, having plans that address the health care needs of family members, and higher self-reported health status were associated with all 3 workforce preparedness variables. Clinical staff (compared to non-clinical staff) were less likely (OR:0.80, 95% CI:0.68-0.94, P < .01) to have confidence in their medical facility’s ability to respond but more likely (OR:1.77, 95% CI:1.49-2.10, P < .001) to believe their role was important. Employees who have been at the VA longer (OR:1.07, 95% CI:1.01-1.14, P < .05) or have experienced a disaster while working at the VA (OR:1.29, 95% CI:1.04-1.59, P < .05) were more likely to understand their role during a pandemic.Conclusion:The findings from this study suggest the need for identifying ways to increase VA employees’ confidence in their medical facility’s ability to respond to a pandemic; develop trainings to improve understanding of their different yet critical roles, for both clinical and non-clinical staff, during a pandemic; create different workforce trainings for newly hired employees; and identify ways to improve household preparedness for a pandemic outbreak.

Resolving the Burden of Low Back Pain in Military Service Members and Veterans (RESOLVE): Protocol for a Multisite Pragmatic Clinical Trial.

Physical therapy (PT) is frequently used for the management of low back pain (LBP) within the US Departments of Defense (DOD) and Veterans Affairs (VA). However, variations in PT practice patterns and use of ineffective interventions lower the quality and increase the cost of care. Although adherence to the clinical practice guidelines (CPGs) can improve the outcomes and cost-effectiveness of LBP care, PT CPG adherence remains below 50%. The Resolving the Burden of Low Back Pain in Military Service Members and Veterans (RESOLVE) trial will evaluate the effectiveness of an active PT CPG implementation strategy using an education, audit, and feedback model for reducing pain, disability, medication use, and cost of LBP care within the DOD and VA health care systems. The RESOLVE trial will include 3,300 to 7,260 patients with LBP across three DOD and two VA medical facilities using a stepped-wedge study design. An education, audit, and feedback model will be used to encourage physical therapists to better adhere to the PT CPG recommendations. The Oswestry Disability Index and the Defense and Veterans Pain Rating Scale will be used as primary outcomes. Secondary outcomes will include the LBP-related medication use, medical resource utilization, and biopsychosocial predictors of outcomes. Statistical analyses will be based on the intention-to-treat principle and will use linear mixed models to compare treatment conditions and examine the interactions between treatment and subgrouping status (e.g., limb loss). The RESOLVE trial will provide a pragmatic approach to evaluate whether better adherence to PT CPGs can reduce pain, disability, medication use, and LBP care cost within the DOD and VA health care systems.

Racial Differences in the Cesarean Section Rates Among Women Veterans Using Department of Veterans Affairs Community Care.

Racial disparities in maternal morbidity and mortality remain a pressing public health problem. Variations in cesarean section (C-section) rates among racial and ethnic groups have been well documented, though reasons for these variations remain unknown. In the Department of Veterans Affairs (VA), nearly half of all women Veterans are of reproductive age and >40% of these women are racial and ethnic minorities. Because the VA does not provide obstetrical services, all obstetrical care is provided by community obstetrical providers under the auspices of the VA Community Care Network. However, little is known regarding the rates and correlates of C-sections among women Veterans receiving community obstetrical care. To examine predictors of C-section deliveries among a cohort of racially diverse pregnant Veterans enrolled in VA care at 15 VA medical facilities nationwide. Cross-sectional analysis of a longitudinal, prospective, multisite, observational cohort study of pregnant, and postpartum Veterans receiving community-based obstetrical care. Overall, 659 Veterans delivered babies during the study period, and 35% of the deliveries were C-sections. Predictors of C-section receipt included being a woman of color [adjusted odds ratio (AOR), 1.76; 95% confidence interval (CI), 1.19-2.60], having an Edinburgh Postnatal Depression Scale score ≥10 (AOR, 1.71; 95% CI, 1.11-2.65), having a higher body mass indexes (AOR, 1.07; 95% CI, 1.04-1.11), and women who were older (AOR, 1.08; 95% CI, 1.03-1.13). There was a substantial racial variation in C-section rates across our 15 study sites, with C-section rates meeting or exceeding 50% for WOC in 8 study sites. There is substantial racial and geographic variation in C-section rates among pregnant Veterans receiving obstetrical care through VA community care providers. Future research should carefully examine variations in C-sections by the hospital, and which providers and hospitals are included in VA contracts. There should also be an increased focus on the types of providers women Veterans have access to for obstetrical care paid for by the VA and the quality of care delivered by those providers.

Workforce preparedness for disasters: perceptions of clinical and non-clinical staff at the U.S. Department of Veterans Affairs

BackgroundMost U.S. studies on workforce preparedness have a narrow scope, focusing primarily on perceptions of clinical staff in a single hospital and for one type of disaster. In contrast, this study compares the perceptions of workplace disaster preparedness among both clinical and non-clinical staff at all U.S. Department of Veterans Affairs (VA) medical facilities nationwide for three types of disasters (natural, epidemic/pandemic, and manmade).MethodsThe VA Preparedness Survey used a stratified simple random, web-based survey (fielded from October through December 2018) of all employees at VA medical facilities. We conducted bivariate and multivariate logistic regression analyses to compare the sociodemographic characteristics and perceptions of disaster preparedness between clinical and non-clinical VA staff.ResultsThe study population included 4026 VA employees (2488 clinicians and 1538 non-clinicians). Overall, VA staff were less confident in their medical facility’s ability to respond to epidemic/pandemics and manmade disasters. Depending on the type of disaster, clinical staff, compared to non-clinical staff, were less likely to be confident in their VA medical facility’s ability to respond to natural disasters (OR:0.78, 95% CI:0.67–0.93, p < 0.01), pandemics (OR:0.82, 95% CI:0.70–0.96, p < 0.05), and manmade disasters (OR: 0.74, 95% CI: 0.63–0.86, p < 0.001). On the other hand, clinicians, compared to non-clinicians, were 1.45 to 1.78 more likely to perceive their role in disaster response to be important (natural OR:1.57, 95% CI:1.32–1.87; pandemic OR:1.78, 95% CI:1.51–2.10; manmade: OR:1.45; 95% CI: 1.23–1.71; p’s < 0.001), and 1.27 to 1.29 more likely to want additional trainings to prepare for all three types of disasters (natural OR:1.29, 95% CI:1.10–1.51; pandemic OR:1.27, 95% CI:1.08–1.49; manmade OR:1.29; 95% CI:1.09–1.52; p’s < 0.01). Clinicians were more likely to be women, younger, and more educated (p’s < 0.001) than non-clinicians. Compared to clinicians, non-clinical staff had been employed longer with the VA (p < 0.025) and were more likely to have served in the U.S. Armed Forces (p < 0.001).ConclusionsThese findings suggest both a desire and a need for additional training, particularly for clinicians, and with a focus on epidemics/pandemics and manmade disasters. Training programs should underscore the importance of non-clinical roles when responding to disasters.

Veterans groups, government brace for surge in MH needs

The U.S. Department of Veterans Affairs (VA) and its partner mental health providers have kept thousands of veterans in treatment during the COVID‐19 pandemic through telehealth appointments, The Associated Press reported May 11. But as job losses and increased social isolation take an extended toll, some veterans' advocates worry the already understaffed VA medical facilities can't keep up and that telehealth isn't enough. The VA on May 8 kicked off a “Now Is the Time” campaign aimed at alerting veterans and their families to the mental health resources that are available to them. But veterans' advocates still are waiting for a report by a White House task force established by President Donald Trump last year that was charged with developing a national roadmap to boost mental health care and stem persistently high suicide numbers among veterans, who have been hard hit in the pandemic. Release of the task force report had been scheduled in March but was abruptly shelved due to the outbreak. VA Secretary Robert Wilkie told veterans groups in a call last week that the draft report was being finalized but declined to give a release date.

Implementation of Legionella Prevention Policy in Health Care Facilities: The United States Veterans Health Administration Experience.

The Veterans Health Administration requires implementation of Legionella prevention policy in potable water systems at Department of Veterans Affairs (VA) medical facilities across the United States and territories. The Veterans Health Administration Central Office program offices with expertise in engineering and clinical aspects of Legionella prevention policy have provided joint, structured on-site assistance to VA medical facilities for consultation on policy implementation. Site visits included review of facility documentation and data, discussions with staff, touring of buildings, and development of recommendations. Information obtained from on-site consultative assistance provided to VA medical facilities from December 2012 through January 2018 was reviewed to identify engineering and clinical challenges and lessons from implementation of Legionella prevention policy in VA health care buildings. Fifteen consultative site visits were conducted during this period regarding implementation of Legionella prevention and validation of effectiveness. It was found that implementation of Legionella prevention policy in potable water systems was complex and practices varied for each building. Common implementation challenges included capability of applying engineering controls, water stagnation, and assessment of health care association of Legionella cases. Process challenges included routine verification of actions, methods for assessing environmental validation data, and documentation of requirements. It was found that consistent and data-driven implementation of policy is crucial for an effective program. Guidance and standards documents in the community for Legionella prevention in building water systems are often general in nature, but implementation requires specific decisions and routine assessments and modifications to optimize outcomes. This real-world review of challenges and lessons from a large health care system with a detailed primary Legionella prevention policy informs future development of guidance and policy, both within and external to VA, and can provide insight to other health care facilities planning to implement practices for water safety.

Courses of suicidal ideation among military veterans in residential treatment for posttraumatic stress disorder.

Suicidal thoughts are common among veterans with posttraumatic stress disorder (PTSD). The aim of this study was to examine the prevalence and correlates of four courses of suicidal (SI) among veterans receiving residential PTSD treatment. A total of 1,807 veterans receiving residential PTSD treatment at Department of Veterans Affairs medical facilities who completed self-report measures at admission and discharge were included. The prevalence of SI courses were No SI (33.6%), Remitted SI (23.0%), SI onset (6.0%), and Chronic SI (37.4%). There were group differences between the four SI courses in PTSD symptoms at baseline, magnitude of PTSD symptom change during treatment, race/ethnicity and baseline depression, substance use, physical functioning, and pain. Chronic SI was associated with highest baseline PTSD, depression, substance use, pain and worse physical functioning. Remitted SI course was associated with greatest pre-posttreatment PTSD improvement, followed by No SI, Chronic SI, and SI Onset. Multinomial logistic regressions revealed that PTSD symptom improvement and baseline PTSD symptoms most consistently related to symptomatic SI courses compared to less symptomatic or No SI courses. Receipt of trauma-focused psychotherapy (none, some, or adequate) and length of stay were not related to SI courses and did not differ between groups. Findings indicate that treating PTSD symptoms could be impactful for reducing suicidal thoughts. Although many veterans had remitted or reduced severity of SI at discharge, a significant proportion of veterans reported SI at discharge (43.4%), potentially highlighting the need for suicide specific treatment interventions within the context of PTSD treatment.

1230. Estimating Effective Point-of-Use Biocide Levels for Legionella Control in Building Water Systems Using a Large, Real-World Dataset

BackgroundLegionnaires’ disease is a potentially life-threatening illness often associated with Legionella growth in water sources. Oxidizing biocides, such as chlorine (CL), monochloramine (MC) and chlorine dioxide (CD), can reduce Legionella contamination. However, limited guidance exists regarding optimal target biocide levels in building water systems to prevent Legionella growth. We examined Legionella and biocide data collected by Department of Veterans Affairs medical facilities nationally to estimate effective biocide levels.MethodsWater samples collected at point of use for routine surveillance purposes between 2015 and 2017 were used for this analysis. Samples were limited to those with reported biocide being CL, MC or CD. Samples with biocide levels above safe drinking water maximums and from nonpotable water sources were excluded. Samples were stratified by hot and cold water and univariate logistic generalized additive models were used to assess nonlinear associations of probability of Legionella positivity and biocide level.ResultsThe dataset included 144,458 samples (cold: 72,674; hot: 71,784) from 789 buildings at 168 hospitals, with 99,419 samples with reported biocide as CL, 40,922 as MC, and 4,117 as CD. For CL, cold water analysis showed a minimum probability of positivity at approximately 0.5 parts per million (ppm), but with a second minimum at 2 ppm. Hot water showed an inflection point around 0.6 ppm, but the likelihood of positivity continued to decrease until plateauing beyond 2 ppm (Figure 1). Cold water with MC showed a minimum probability of positivity at 0.3 ppm followed by a second minimum at 1.7 ppm with plateau beyond that concentration. Hot water showed a similar graph with initial minimum at 0.25 ppm and a second minimum at 1.6 ppm (Figure 2). CD graphs for both hot and cold showed a decrease at 0.2 ppm (Figure 3).ConclusionThe variability in the dynamics of Legionella inhibition by different biocides as seen in our analysis indicates minimum biocide targets for the different agents. For CL and MC, biocide levels >2 ppm at point of use in building water systems may not provide added benefit for suppression of Legionella. Disclosures All authors: No reported disclosures.

1864. Implementation of the National Healthcare Safety Network’s (NHSN) Antimicrobial Use Option in the US Veterans Affairs (VA) Medical Facilities

BackgroundInappropriate or unnecessary use of antibiotics exacerbates antimicrobial resistance and can lead to adverse clinical outcomes. To address this issue, NHSN created the Antimicrobial Use (AU) Option to report antimicrobial use within acute care facilities. A pilot program was started to implement AU reporting in VA in 2013.MethodsWith support from VA Antimicrobial Stewardship Task Force and NHSN, we deployed one team to focus on implementation and another on technical aspects. We used an iterative recruitment approach with four cohorts to date (Tiers), starting with highly engaged facilities with strong stewardship infrastructure. Our implementation approach (Figure 1) was based on the Promoting Action on Research Implementation (PARiHS) framework for successful implementation of evidence into clinical practice. We evaluated our implementation with focus groups conducted using Skype chat to collect feedback from participants about the implementation process. Group 1 contained six participants from Tiers 1 and 2. Group 2 had three participants from Tiers 3 and 4. Questions were constructed using the PARiHS framework (Table 1). An implementation team member conducted interviews, monitored the discussion, then coded major themes of responses. ResultsTo date, there are over 90 facilities reporting AU to NHSN. Major themes to responses are summarized in Table 1. Overall, focus group participants were supportive of the program, but there were differences between early and later adopters.ConclusionA coordinated, centralized approach to facilitating implementation of NHSN AU reporting has been successful so far. Major themes from focus group responses did differ in some categories depending on tier in a way that appears concordant with the theory diffusion of innovation, e.g., early tiers were enthusiastic despite a lack of institutional support while later tiers reported being motivated by regulatory requirements and had solid institutional support. More research would further inform how to efficiently implement complex programs in large systems.Disclosures All authors: No reported disclosures.

The Psychological Risk of Minimal Risk Activities: A Pre- and Posttest Study Using the Self-Assessment Manikin

It is difficult to apply U.S. Federal Code of Regulation's criterion for "minimal risk," because benchmarks of minimal risk have not been quantified. Our goal was to examine the psychological risks of several day-to-day activities. Using the Self-Assessment Manikin (SAM), we assessed the state valence and arousal of 432 patients and employees at a large Midwestern Department of Veterans Affairs medical facility before and after they had their blood drawn, saw their primary care physician or mental health provider, or took part in an exercise class. Exercise was associated with near-large to large salutary effects (Cohen's d = 0.76-1.17); other effects were small or moderate in positive directions (Cohen's d = 0.02-0.51). Our findings are a promising start toward establishing benchmarks and quantifying the psychological harms of minimal risk activities. Estimates such as these may help researchers determine whether their own research exceeds minimal risk.

Adapting Coordinated Anxiety Learning and Management for Veterans Affairs Community-Based Outpatient Clinics: Iterative Approach.

BackgroundA national priority at the US Department of Veterans Affairs (VA) is to increase the availability and accessibility of evidence-based psychotherapies (EBPs) across all VA medical facilities. Yet many veterans, particularly those who use remote outpatient VA clinics, still do not receive much needed evidence-based treatment. Strategies are needed for supporting mental health providers at rural VA community-based outpatient clinics (CBOCs) as they translate their clinical training to routine practice. The Coordinated Anxiety Learning Management (CALM) program is a computer-delivered program that supports the delivery of cognitive behavioral therapy (CBT) by providers in outpatient settings to patients with depression and anxiety, including posttraumatic stress disorder.ObjectiveThe objectives of our study were to (1) adapt an existing computer-based program to rural VA CBOCs through feedback from key stakeholder focus groups; (2) develop a prototype of the adapted program; and (3) determine the adapted program’s acceptability and feasibility. Mental health stakeholders included VA leaders (n=4) in the implementation of EBPs, VA experts (n=4) in CBT, VA CBOC mental health providers (n=8), and veterans (n=8) diagnosed with a mental health condition treated using the CALM program and receiving treatment in a VA CBOC.MethodsAn iterative approach comprising 3 waves of focus group discussions was used to develop a modified prototype of CALM. Following each wave of focus group discussions, template analysis was used to rapidly communicate stakeholder recommendations and feedback to the design team. The original program was first adapted through a process of data collection, design modification, and product development. Next, a prototype was developed. Finally, the redesigned program was tested for acceptability and feasibility through a live demonstration.ResultsKey stakeholders suggested modifications to the original CALM program that altered its modules’ appearance by incorporating veteran-centric content. These modifications likely have no impact on the integrity of the original CALM program, but have altered its content to reflect better the demographic characteristics and experiences of rural veterans. Feedback from stakeholder groups indicates that changes will help VA patients identify with the program content, potentially enhancing their treatment engagement.ConclusionsThe development model was effective for economically gathering actionable recommendations from stakeholders to adapt a computer-based program, and it can result in the development of an acceptable and feasible computer-delivered intervention. Results have implications for developing computer-based programs targeting behavior change more broadly and enhancing engagement in EBP.

Legionnaires Disease Surveillance in US Department of Veterans Affairs Medical Facilities and Assessment of Health Care Facility Association

Legionnaires disease (LD) incidence is increasing in the United States. Health care facilities are a high-risk setting for transmission of Legionella bacteria from building water systems to occupants. However, the contribution of LD in health care facilities to national LD rates is not well characterized. To determine the burden of LD in US Department of Veterans Affairs (VA) patients and to assess the amount of LD with VA exposure. Retrospective cohort study of reported LD data in VA medical facilities in a national VA LD surveillance system from January 1, 2014, to December 31, 2016. The study population included total veteran enrollees and enrollees who used the VA health care system. The primary outcome was assessment of annual LD rates, categorized by VA and non-VA exposure. Legionnaires disease rates for cases with VA exposure were determined on both population and exposure potential levels. Rates by VA exposure potential were calculated using inpatient bed days of care, long-term care resident days, or outpatient encounters. In addition, types and amounts of LD diagnostic testing were calculated. Case and testing data were analyzed nationally and regionally. There were 491 LD cases in the case report surveillance system from January 1, 2014, to December 31, 2016. Most cases (447 [91%]) had no VA exposure or only outpatient VA exposure. The remaining 44 cases had VA exposure from overnight stays. Total LD rates from January 1, 2014, to December 31, 2016, increased for all VA enrollees (from 1.5 to 2.0 per 100 000 enrollees; P = .04) and for users of VA health care (2.3 to 3.0 per 100 000 enrollees; P = .04). The LD rate for the subset who had no VA exposure also increased (0.90 to 1.47 per 100 000 enrollees; P < .001). In contrast, the LD rate for patients with VA overnight stay decreased on a population level (5.0 to 2.3 per 100 000 enrollees; P < .001) and an exposure level (0.31 to 0.15 per 100 000 enrollees; P < .001). Regionally, the eastern United States had the highest LD rates. The urine antigen test was the most used LD diagnostic method; 49 805 tests were performed in 2015-2016 with 335 positive results (0.67%). Data in the VA LD databases showed an increase in overall LD rates over the 3 years, driven by increases in rates of non-VA LD. Inpatient VA-associated LD rates decreased, suggesting that the VA's LD prevention efforts have contributed to improved patient safety.

A Brief Exposure-Based Treatment vs Cognitive Processing Therapy for Posttraumatic Stress Disorder: A Randomized Noninferiority Clinical Trial

ImportanceWritten exposure therapy (WET), a 5-session intervention, has been shown to efficaciously treat posttraumatic stress disorder (PTSD). However, this treatment has not yet been directly compared with a first-line PTSD treatment such as cognitive processing therapy (CPT).ObjectiveTo determine if WET is noninferior to CPT in patients with PTSD.Design, Setting, and ParticipantsIn this randomized clinical trial conducted at a Veterans Affairs medical facility between February 28, 2013, and November 6, 2016, 126 veteran and nonveteran adults were randomized to either WET or CPT. Inclusion criteria were a primary diagnosis of PTSD and stable medication therapy. Exclusion criteria included current psychotherapy for PTSD, high risk of suicide, diagnosis of psychosis, and unstable bipolar illness. Analysis was performed on an intent-to-treat basis.InterventionsParticipants assigned to CPT (n = 63) received 12 sessions and participants assigned to WET (n = 63) received 5 sessions. The CPT protocol that includes written accounts was delivered individually in 60-minute weekly sessions. The first WET session requires 60 minutes while the remaining 4 sessions require 40 minutes.Main Outcomes and MeasuresThe primary outcome was the total score on the Clinician-Administered PTSD Scale for DSM-5; noninferiority was defined by a score of 10 points. Blinded evaluations were conducted at baseline and 6, 12, 24, and 36 weeks after the first treatment session. Treatment dropout was also examined.ResultsFor the 126 participants (66 men and 60 women; mean [SD] age, 43.9 [14.6] years), improvements in PTSD symptoms in the WET condition were noninferior to improvements in the CPT condition at each of the assessment periods. The largest difference between treatments was observed at the 24-week assessment (mean difference, 4.31 points; 95% CI, –1.37 to 9.99). There were significantly fewer dropouts in the WET vs CPT condition (4 [6.4%] vs 25 [39.7%]; χ21 = 12.84, Cramer V = 0.40).Conclusions and RelevanceAlthough WET involves fewer sessions, it was noninferior to CPT in reducing symptoms of PTSD. The findings suggest that WET is an efficacious and efficient PTSD treatment that may reduce attrition and transcend previously observed barriers to PTSD treatment for both patients and providers.Trial Registrationclinicaltrials.gov Identifier: NCT01800773

Access to Care for Homeless Veterans During Disasters

Introduction: Since 1970, natural disasters have led to both temporary and permanent closures of multiple medical centers and outpatient clinics at the US Department of Veterans Affairs (VA) nationwide. Access to care during such events is critical for vulnerable populations, especially homeless veterans. As such, facility closures may disproportionately affect homeless veteran patients who are both more likely to experience adverse effects from disasters and face multiple barriers to care. Methods: A cross-sectional survey was administered to a probability sample of 2000 homeless VA patients living in and receiving VA health care in the Northeast United States. The survey was completed by 383 respondents (20% adjusted response rate). This pilot study examines predictors of difficulty accessing care in the event that the VA facility that homeless VA patients routinely use is forced to close because of a natural disaster. Results: In a multivariate logistic regression, homeless VA patients who had Medicaid were less likely (OR 0.38; 95% CI: 0.18-0.78; P < .01) to report that they would have difficulty obtaining care elsewhere if their normal VA facility was closed in a future natural disaster. Conclusions: Findings suggest that Medicaid coverage has the potential to facilitate access to care for homeless veteran VA patients during disasters. Policy changes that decrease Medicaid coverage could limit access to care for homeless veterans during closures of VA medical facilities.

Abstract C41: No difference in mortality between racial groups after prostate cancer diagnosis given equal access to health care

Abstract Introduction: Prostate cancer (PCa) is the leading incident cancer and the second leading cause of cancer death among American men. African Americans (AAs) suffer a disproportionate burden of disease with 1.5 times higher incidence and more than double the mortality rates of European American (EA) men. AAs tend to be diagnosed with more virulent forms of the disease and at earlier ages than other racial/ethnic groups, which cannot be explained completely by differences in socioeconomic status or access to care. However, it is unclear whether there is significant difference in mortality between racial groups after PCa diagnosis (Dx) given equal access to health care. This study will evaluate if the mortality of AA is higher than other racial groups after PCa Dx using data from five Veterans Affairs (VA) medical facilities in the mid-south region. Methods: A retrospective review of medical records from five VA hospitals in the mid-south was conducted. All prostate cancer patients diagnosed between January 2009 and December 2014 at these hospitals were included. Primary endpoint was overall survival. Vital status of patients was updated through December 2015. PCa patients were categorized into 3 categories of aggressiveness, i.e., high, intermediate, and low, based on clinical presentation at Dx, including Prostate-specific antigen (PSA) levels, Gleason Sum, and cancer stage. Multivariate Cox proportional hazard models were used to examine the risk of mortality after PCa Dx adjusting for age, marital status, tobacco history, alcohol history, PCa aggressiveness, and first course of treatment option with race as the primary predictive factor. Results: After excluding 23 patients who did not report race, 11 pacific islanders, and 27 American Indian, Aleutian, Eskimo/Asian Indian, the dataset included 4,740 PCa patients of which, 2,327 patients were EAs and 2,413 were AAs. During this five year period, 545 deaths were reported, where 50.5% were EAs and 49.5% were AAs. As expected, high PCa aggressiveness vs. low/intermediate aggressiveness (Hazard Ratio (HR) = 1.33, 95% Confidence Interval (CI) = 1.08-1.63), distant metastasis at Dx (HR = 5.05, 95%CI = 3.81-6.71), and age (HR = 1.07, 95%CI = 1.06-1.07) were statistically significantly associated with mortality after PCa Dx. Using radiation therapy as reference, surgery as the first course of treatment (HR = 0.61, 95%CI = 0.45-0.82) was inversely associated with mortality after PCa Dx, while hormonal therapy and active surveillance were not significantly associated with mortality after PCa Dx. However, a non-statistically significant association was observed between AAs and mortality (HR=1.14, 95% CI=0.96-1.35, p = 0.14) when compared to EAs. Conclusion: There was no significant difference between AAs and EAs in mortality after PCa Dx in this medical review of PCa patients in five VA hospitals in the mid-south. Although genetic, environmental, and lifestyle factors may contribute to the difference in PCa mortality observed between racial groups, AA race is not a significant contributor to death when given equal access to health care, such as in the VA hospital setting.
