Suicide Prevention Programs Currently Available to US Veterans: A Scoping Review

It is widely recognized the high suicide rate among United States (US) veterans is a major ongoing public health problem. Suicide prevention programs that specifically target veterans are varied in their implementation and success rates. A scoping review was conducted to examine what types of suicide prevention programs are currently available for US veterans and their effectiveness. From this scoping review, 361 articles were located from two electronic databases, and 26 suicide prevention programs were located through the US Department of Veterans Affairs (VA) webpage/electronic resources. Of the 361 peer reviewed articles, 33 were classified as highly relevant and selected for full review, and 22 were identified as needing further review for relevance to the topic or target population. Nineteen VA webpage/electronic resources were classified as highly relevant and selected for full review. After implementing the inclusion and exclusion criteria, 28 journal articles and 16 VA webpage/electronic resources were included in this scoping review. Although the scoping review demonstrated there is a wide variety of suicide prevention programs available for US veterans, the review also indicated that (a) suicide prevention programs in use by the VA are not being widely disseminated in the peer-reviewed literature and (b) there is significantly more dissemination on the study of causes of suicidality than programs being implemented to prevent suicidal behavior. As a result, available research suggests additional research should be conducted on suicide prevention programs and more dissemination of current suicide prevention activities should take place.

Organizational and Implementation Factors Associated with Cirrhosis Care in the Veterans Health Administration.

The Veterans Health Administration provides care to more than 100,000 Veterans with cirrhosis. This implementation evaluation aimed to understand organizational resources and barriers associated with cirrhosis care. Clinicians across 145 Department of Veterans Affairs (VA) medical centers (VAMCs) were surveyed in 2022 about implementing guideline-concordant cirrhosis care. VA Corporate Data Warehouse data were used to assess VAMC performance on two national cirrhosis quality measures: HCC surveillance and esophageal variceal surveillance or treatment (EVST). Organizational factors associated with higher performance were identified using linear regression models. Responding VAMCs (n = 124, 86%) ranged in resource availability, perceived barriers, and care processes. In multivariable models, factors independently associated with HCC surveillance included on-site interventional radiology and identifying patients overdue for surveillance using a national cirrhosis population management tool ("dashboard"). EVST was significantly associated with dashboard use and on-site gastroenterology services. For larger VAMCs, the average HCC surveillance rate was similar between VAMCs using vs. not using the dashboard (47% vs. 41%), while for smaller and less resourced VAMCs, dashboard use resulted in a 13% rate difference (46% vs. 33%). Likewise, higher EVST rates were more strongly associated with dashboard use in smaller (55% vs. 50%) compared to larger (57% vs. 55%) VAMCs. Resources, barriers, and care processes varied across diverse VAMCs. Smaller VAMCs without specialty care achieved HCC and EVST surveillance rates nearly as high as more complex and resourced VAMCs if they used a population management tool to identify the patients due for cirrhosis care.

Knowledge Graph Analysis for Chronic Diseases Nursing based on Visualization Technology and Literature Big Data

The use of knowledge graph analysis for chronic disease nursing based on visualization technology and literature big data is an unexplored area of research in this field of study. To uncover research hotspots and developmental trends in the field of chronic disease nursing, and to provide a scholarly reference, we employed mathematical and statistical methods along with CiteSpace literature visualization analysis software for quantitative analysis of extensive literature data from the Web of Science Core Collection. We examined aspects such as publication trends, journals, author collaborations, research institutions, national and regional distributions, keyword co-occurrence, clustering, time zones, emergence, literature co-citations, and more. These analyses identified the current hotspots and future directions for research. Notably, scholars' interest in chronic disease nursing exhibited a consistent upward trajectory. In particular, the field of artificial intelligence technology application in nursing yielded $3,610$ published papers in $141$ journals with more than or equal to $10$ published papers on the topic, accounting for $58.41 \%$ of the total number of published papers in this field of study. Furthermore, the top three publishers were the “Journal of Clinical Nursing,” “Journal of Advanced Nursing,” and “BMC Health Services Research.” Among authors, Hu, Frank B., Willett, Walter C., and Rimm, Eric B., ranked as the top three, and 12 authors had more than 10 publications. The most active research institutions included Harvard University, Harvard Medical School, Brigham & Women’s Hospital, University of California System, University of London, US Department of Veterans Affairs, Veterans Health Administration (VHA), Harvard T. H. Chan School of Public Health, University of Sydney, and the University of Toronto. The United States, Australia, England, China, Canada, Netherlands, Spain, Italy, Sweden, and Germany emerged as the leading countries in terms of research output, while emerging hotspots encompassed topics such as incidence, rheumatoid arthritis, qualitative research, burnout, kidney transplantation, critical illness, COVID-19, Sars-COV-2, public health, and the well-being of medical staff. These findings present valuable insights for prospective research endeavors.

Emergency Department Use Among Combat and Non-Combat Post-9/11 Military Veterans.

Most post-9/11 Veterans have completed at least 1 combat deployment-a known factor associated with adverse health outcomes. Such Veterans are known to have unmet health care needs, and the emergency department (ED) may serve as a safety net, yet little is known about whether combat status is associated with more frequent ED use. We sought to evaluate the relationship between combat status and frequency of ED use among post-9/11 Veterans and assess the most common reasons for ED visits. This retrospective cohort study consisted of post-9/11 Veterans who enrolled in U.S. Department of Veterans Affairs (VA) care between fiscal years (FYs) 2005 and 2015. Data were obtained from the VA Corporate Data Warehouse. Incidence rates for ED visits for combat and non-combat Veterans were compared from FY 2010 to 2019 using zero-inflated negative binomial regression. The most frequent reasons for ED visits were determined using International Classification of Diseases codes. This study was approved by the Stanford Institutional Review Board. Among 1.3 million Veterans included in analyses, 70.4% had deployed to a combat zone. The mean (SD) age of our cohort was 32.6 (5.0) years and 83.5% of Veterans were male. After controlling for other factors, combat Veterans had 1.84 times the rate of ED visits compared to non-combat Veterans (95% CI, 1.83-1.85). Only combat Veterans had a mental health-related ED visit (suicidal ideations) among the top 3 reasons for ED presentation. Those who deployed to a combat zone had a significantly higher rate of ED use compared to those who did not. Further, mental health-related ED diagnoses appeared to be more prevalent in combat Veterans. These findings highlight the unique health care needs faced by combat Veterans and emphasize the importance of tailored interventions and support services for this specific population.

EXPRESS: Fluoxetine, Fluvoxamine and Hearing Loss or Tinnitus After Cisplatin Treatment: A Retrospective Cohort Study.

Cisplatin use is often limited by its ototoxic side effects, which can lead to irreversible hearing loss. Preventing cisplatin-induced ototoxicity is crucial to improve patient outcomes. Fluoxetine and fluvoxamine, both SSRI antidepressants, inhibit the NLRP3 inflammasome, a potential therapeutic target for preventing ototoxicity. However, human studies have not evaluated if these antidepressants may protect against cisplatin-induced ototoxicity. The object of this study is to assess the association between fluoxetine or fluvoxamine use and the incidence of hearing loss or tinnitus in a large cohort of patients receiving cisplatin chemotherapy. We use a retrospective cohort study within the U.S. Department of Veterans Affairs (VA) healthcare system. Adult patients with cancer who received cisplatin chemotherapy between 2000 and 2023 are included. Incidence of ototoxicity, defined by ICD-9-CM or ICD-10-CM diagnoses of hearing loss or tinnitus is compared between concurrent use of fluoxetine or fluvoxamine and cisplatin alone. A total of 20,552 patients were included. Of those, 489 received cisplatin and fluoxetine or fluvoxamine. After propensity score adjustment, the hazard of ototoxicity was lower in the group receiving fluoxetine or fluvoxamine compared to the group receiving cisplatin alone (HR=0.62, 95% CI=(0.41-0.94)). Fluoxetine or fluvoxamine use may be associated with a reduced risk of cisplatin-induced ototoxicity. Randomized clinical trials are needed to confirm these findings and establish the efficacy of the medications in ototoxicity prevention. Further research is also warranted to investigate the potential mechanisms underlying this protective effect.

RE-AIM for rural health innovations: perceptions of (mis) alignment between the RE-AIM framework and evaluation reporting in the Department of Veterans Affairs Enterprise-Wide Initiatives program

BackgroundThe Department of Veterans Affairs (VA) Office of Rural Health (ORH) supports national VA program offices' efforts to expand health care to rural Veterans through its Enterprise-Wide Initiatives (EWIs) program. In 2017, ORH selected Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM), an implementation science framework, to structure the EWI evaluation and reporting process. As part of its mandate to improve EWI program evaluation, the Center for the Evaluation of Enterprise-Wide Initiatives conducted a qualitative evaluation to better understand EWI team' perceptions of, and barriers and facilitators to, the EWI evaluation process.MethodsWe conducted 43 semi-structured interviews with 48 team members (e.g., evaluators, program office leads, and field-based leads) representing 21 EWIs from April-December 2020. Questions focused on participants' experiences using strategies targeting each RE-AIM dimension. Interviews were inductively analyzed in MAXQDA. We also systematically reviewed 51 FY19-FY20 EWI annual reports to identify trends in misapplications of RE-AIM.ResultsParticipants had differing levels of experience with RE-AIM. While participants understood ORH's rationale for selecting a common framework to structure evaluations, the perceived misalignment between RE-AIM and EWIs' work emerged as an important theme. Concerns centered around 3 sub-themes: (1) (Mis)Alignment with RE-AIM Dimensions, (2) (Mis)Alignment between RE-AIM and the EWI, and (3) (Mis)Alignment with RE-AIM vs. other Theories, Models, or Frameworks. Participants described challenges differentiating between and operationalizing dimensions in unique contexts. Participants also had misconceptions about RE-AIM and its relevance to their work, e.g., that it was meant for established programs and did not capture aspects of initiative planning, adaptations, or sustainability. Less commonly, participants shared alternative models or frameworks to RE-AIM. Despite criticisms, many participants found RE-AIM useful, cited training as important to understanding its application, and identified additional training as a future need.DiscussionThe selection of a shared implementation science framework can be beneficial, but also challenging when applied to diverse initiatives or contexts. Our findings suggest that establishing a common understanding, operationalizing framework dimensions for specific programs, and assessing training needs may better equip partners to integrate a shared framework into their evaluations.

VA Providers' Perceptions of Cannabis Use Policies in a Legalized and Nonlegalized State.

Background: Providers in the Department of Veterans Affairs (VA) system are caught between two opposing sets of laws regarding cannabis and cannabidiol (CBD) use by their patients. As VA is a federal agency, it must abide by federal regulations, including that the Food and Drug Administration classifies cannabis as a Schedule 1 drug and therefore cannot recommend or help Veterans obtain it. Meanwhile, 38 states have passed legislation, legalizing medical use of cannabis. Objective: The goal of this project is to examine how VA providers understand state and federal laws, and VA policies about cannabis and CBD use, and to learn more about providers' experiences with patients who use cannabis and CBD within a legalized and nonlegalized state. Materials and Methods: We identified 432 health care providers from two VA facilities in northern Illinois (IL) where medical and recreational cannabis is legal, and two VA facilities in southern Wisconsin (WI) where medical and recreational cannabis is illegal. Participants were invited via e-mail to complete an anonymous online survey, including 31 closed- and open-ended questions about knowledge of state and federal laws and VA policies regarding cannabis and CBD oil, thoughts about the value of cannabis or CBD for treating medical conditions, and behaviors regarding cannabis use by their patients. Results: We received 50 responses (IL N=20, WI N=30). Providers in both states were knowledgeable about cannabis laws in their state but unsure whether they could recommend cannabis. There were more providers who were unclear if they could have a conversation about cannabis with their VA patients in WI compared with IL. Providers were more likely to agree than disagree that cannabis can be beneficial, χ2 (1, 49)=4.74, p=0.030. Providers in both states (81.6%) believe cannabis use is acceptable for end-of-life care, but responses varied for other conditions and symptoms. Discussion: Findings suggest that VA providers could use more guidance on what is allowable within their VA facilities and how state laws affect their practice. Education about safety related to cannabis and other drug interactions would be helpful. There is limited information about possible interactions, warranting future research.

Surveillance for Emerging and Reemerging Pathogens Using Pathogen Agnostic Metagenomic Sequencing in the United States: A Critical Role for Federal Government Agencies.

The surveillance and identification of emerging, reemerging, and unknown infectious disease pathogens is essential to national public health preparedness and relies on fluidity, coordination, and interconnectivity between public and private pathogen surveillance systems and networks. Developing a national sentinel surveillance network with existing resources and infrastructure could increase efficiency, accelerate the identification of emerging public health threats, and support coordinated intervention strategies that reduce morbidity and mortality. However, implementing and sustaining programs to detect emerging and reemerging pathogens in humans using advanced molecular methods, such as metagenomic sequencing, requires making large investments in testing equipment and developing networks of clinicians, laboratory scientists, and bioinformaticians. In this study, we sought to gain an understanding of how federal government agencies currently support such pathogen agnostic testing of human specimens in the United States. We conducted a landscape analysis of federal agency websites for publicly accessible information on the availability and type of pathogen agnostic testing and details on flow of clinical specimens and data. The website analysis was supplemented by an expert review of results with representatives from the federal agencies. Operating divisions within the US Department of Health and Human Services and the US Department of Veterans Affairs have developed and sustained extensive clinical and research networks to obtain patient specimens and perform metagenomic sequencing. Metagenomic facilities supported by US agencies were not equally geographically distributed across the United States. Although many entities have work dedicated to metagenomics and/or support emerging infectious disease surveillance specimen collection, there was minimal formal collaboration across agencies.

Question-answering system extracts information on injection drug use from clinical notes

BackgroundInjection drug use (IDU) can increase mortality and morbidity. Therefore, identifying IDU early and initiating harm reduction interventions can benefit individuals at risk. However, extracting IDU behaviors from patients’ electronic health records (EHR) is difficult because there is no other structured data available, such as International Classification of Disease (ICD) codes, and IDU is most often documented in unstructured free-text clinical notes. Although natural language processing can efficiently extract this information from unstructured data, there are no validated tools.MethodsTo address this gap in clinical information, we design a question-answering (QA) framework to extract information on IDU from clinical notes for use in clinical operations. Our framework involves two main steps: (1) generating a gold-standard QA dataset and (2) developing and testing the QA model. We use 2323 clinical notes of 1145 patients curated from the US Department of Veterans Affairs (VA) Corporate Data Warehouse to construct the gold-standard dataset for developing and evaluating the QA model. We also demonstrate the QA model’s ability to extract IDU-related information from temporally out-of-distribution data.ResultsHere, we show that for a strict match between gold-standard and predicted answers, the QA model achieves a 51.65% F1 score. For a relaxed match between the gold-standard and predicted answers, the QA model obtains a 78.03% F1 score, along with 85.38% Precision and 79.02% Recall scores. Moreover, the QA model demonstrates consistent performance when subjected to temporally out-of-distribution data.ConclusionsOur study introduces a QA framework designed to extract IDU information from clinical notes, aiming to enhance the accurate and efficient detection of people who inject drugs, extract relevant information, and ultimately facilitate informed patient care.

Understanding How Contingency Staffing Programs Can Support Mental Health Services in the Veterans Health Administration.

Introduction: Beginning in 2019, the Department of Veterans Affairs (VA) prioritized improving access to care nationally to deliver virtual care and implemented 18 regionally based Clinical Resource Hubs (CRHs) to meet this priority. This observational study describes the quantity and types of care delivered by CRH Mental Health teams, and the professions of those hired to deliver it. Methods: A retrospective cohort study, based on national VA CRH mental health care utilization data and CRH staffing data for CRH's first 3 years, was conducted. Results: CRH Mental Health teams primarily used Telemental Health (TMH) to provide care (98.1% of all CRH MH encounters). The most common disorders treated included depression, post-traumatic stress disorder, and anxiety disorders. The amount of care delivered overtime steadily increased as did the racial and ethnic diversity of Veterans served. Psychologists accounted for the largest share of CRH staffing, followed by psychiatrists. Conclusions: CRH TMH delivered from a regional hub appears to be a feasible and acceptable visit modality, based on the continuously increasing CRH TMH visit rates. Our results showed that CRH TMH was predominantly used to address common mental health diagnoses, rather than serious mental illnesses. Traditionally marginalized patient populations increased over the 3-year window, suggesting that CRH TMH resources were accessible to many of these patients. Future research should assess barriers and facilitators for accessing CRH TMH, especially for difficult-to-service patient populations, and should consider whether similar results to ours occur when regional TMH is delivered to non-VA patient populations.

Adopting the RE-AIM analytic framework for rural program evaluation: experiences from the Advance Care Planning via Group Visits (ACP-GV) national evaluation.

To support rigorous evaluation across a national portfolio of grants, the United States Department of Veterans Affairs (VA) Office of Rural Health (ORH) adopted an analytic framework to guide their grantees' evaluation of initiatives that reach rural veterans and to standardize the reporting of outcomes and impacts. Advance Care Planning via Group Visits (ACP-GV), one of ORH's Enterprise-Wide Initiatives, also followed the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. ACP-GV is a national patient-centered intervention delivered in a large, veterans integrated healthcare system. This manuscript describes how RE-AIM was used to evaluate this national program and lessons learned from ORH's annual reporting feedback to ACP-GV on their use of the framework to describe evaluation impacts. We used patient, provider, and site-level administrative health care data from the VA Corporate Data Warehouse and national program management databases for federal fiscal years (FY) spanning October 1, 2018-September 30, 2023. Measures included cumulative and past FY metrics developed to assess program impacts. RE-AIM constructs included the following cumulative and annual program evaluation results. ACP-GV reached 54,167 unique veterans, including 19,032 unique rural veterans between FY 2018 to FY 2023. During FY 2023, implementation adherence to the ACP-GV model was noted in 91.7% of program completers, with 55% of these completers reporting a knowledge increase and 14% reporting a substantial knowledge increase (effectiveness). As of FY 2023, 66 ACP-GV sites were active, and 1,556 VA staff were trained in the intervention (adoption). Of the 66 active sites in FY 2023, 27 were sites previously funded by ORH and continued to offer ACP-GV after the conclusion of three years of seed funding (maintenance). Lessons learned developing RE-AIM metrics collaboratively with program developers, implementers, and evaluators allowed for a balance of clinical and scientific input in decision-making, while the ORH annual reporting feedback provided specificity and emphasis for including both cumulative, annual, and rural specific metrics. ACP-GV's use of RE-AIM metrics is a key step towards improving rural veteran health outcomes and describing real world program impacts.

Dental implant failures in Utah and US veteran cohorts.

Approximately, 5.5 million dental implants are estimated to be surgically placed in the United States yearly, with an anticipated long-term failure rate ranging from 3% to 10%. At the Salt Lake City Dental Clinic within the Department of Veterans Affairs (VHA), specific protocols have been established to mandate that clinicians present every dental implant case for review by a committee. To understand the effectiveness of this approach, a comparative data analysis was undertaken to compare local dental implant failure data against national VHA data. Leveraging electronic health records of veterans spanning from 2000 to 2021, we gathered procedural records related to dental implant placement or failure, demographic information, and medical history for individuals who received dental care at various dental clinics within the nationwide VHA network. Subsequently, statistical analyses were conducted using mixed-effects Poisson regression models with cluster-robust standard errors. Incident rate ratios (IRRs) for Utah-specific and nationwide cohorts were ascertained. The Utah VHA dental clinical data showed that there was a slightly lower prevalence of implant failure at 6.7% compared to the national cohort, which had a rate of 6.9%. The implant level failure rates were also low, with 4.20 (confidence interval [CI]: 3.68, 4.81) per 1000 implant placements per year for Utah cohorts. The adjusted IRR indicated a relative 16% reduction in risk among Utah Veterans (IRR 0.84, 95% CI [0.76-0.92]; p < 0.001). The stringent protocols in place at Salt Lake City, which integrate evidence-based practices and expert opinion for evaluating patient suitability for dental implant placement and subsequent care, contributed to the reduced risk among Utah Dental Clinic veterans pool compared to veterans of other states.

Walking the leadership walk: Integrating inclusivity in a large-scale health care organization.

This article focuses on the roles, actions, and resources developed by a group of leaders from the Office of Mental Health and Suicide Prevention (OMHSP) within the Department of Veterans Affairs during the unprecedented times of spring of 2020, when society was shaken by the fears and challenges of COVID-19 as well as social unrest sparked by the murder of George Floyd. We share a summary of our efforts to move beyond platitudes and statements and bring meaningful and sustainable change in justice, equity, diversity, and inclusion within OMHSP and across mental health services in Department of Veterans Affairs. This article is written through the lens of the founding members of the OMHSP's Diversity, Equity, and Inclusion Steering Committee. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Neighborhood Deprivation, Race and Ethnicity, and Prostate Cancer Outcomes Across California Health Care Systems

Non-Hispanic Black (hereafter, Black) individuals experience worse prostate cancer outcomes due to socioeconomic and racial inequities of access to care. Few studies have empirically evaluated these disparities across different health care systems. To describe the racial and ethnic and neighborhood socioeconomic status (nSES) disparities among residents of the same communities who receive prostate cancer care in the US Department of Veterans Affairs (VA) health care system vs other settings. This cohort study obtained data from the VA Central Cancer Registry for veterans with prostate cancer who received care within the VA Greater Los Angeles Healthcare System (VA cohort) and from the California Cancer Registry (CCR) for nonveterans who received care outside the VA setting (CCR cohort). The cohorts consisted of all males with incident prostate cancer who were living within the same US Census tracts. These individuals received care between 2000 and 2018 and were followed up until death from any cause or censoring on December 31, 2018. Data analyses were conducted between September 2022 and December 2023. Health care setting, self-identified race and ethnicity (SIRE), and nSES. The primary outcome was all-cause mortality (ACM). Cox proportional hazards regression models were used to estimate hazard ratios for associations of SIRE and nSES with prostate cancer outcomes in the VA and CCR cohorts. Included in the analysis were 49 461 males with prostate cancer. Of these, 1881 males were in the VA cohort (mean [SD] age, 65.3 [7.7] years; 833 Black individuals [44.3%], 694 non-Hispanic White [hereafter, White] individuals [36.9%], and 354 individuals [18.8%] of other or unknown race). A total of 47 580 individuals were in the CCR cohort (mean [SD] age, 67.0 [9.6] years; 8183 Black individuals [17.2%], 26 206 White individuals [55.1%], and 13 191 individuals [27.8%] of other or unknown race). In the VA cohort, there were no racial disparities observed for metastasis, ACM, or prostate cancer-specific mortality (PCSM). However, in the CCR cohort, the racial disparities were observed for metastasis (adjusted odds ratio [AOR], 1.36; 95% CI, 1.22-1.52), ACM (adjusted hazard ratio [AHR], 1.13; 95% CI, 1.04-1.24), and PCSM (AHR, 1.15; 95% CI, 1.05-1.25). Heterogeneity was observed for the racial disparity in ACM in the VA vs CCR cohorts (AHR, 0.90 [95% CI, 0.76-1.06] vs 1.13 [95% CI, 1.04-1.24]; P = .01). No evidence of nSES disparities was observed for any prostate cancer outcomes in the VA cohort. However, in the CCR cohort, heterogeneity was observed for nSES disparities with ACM (AHR, 0.82; 95% CI, 0.80-0.84; P = .002) and PCSM (AHR, 0.86; 95% CI, 0.82-0.89; P = .007). Results of this study suggest that racial and nSES disparities were wider among patients seeking care outside of the VA health care system. Health systems-related interventions that address access barriers may mitigate racial and socioeconomic disparities in prostate cancer.

Examining bias in the award of Veterans Affairs (VA) disability benefits for posttraumatic stress disorder in women veterans: Analysis of evaluation reports and VA decisions.

Studies have raised concerns about possible inequities in the U.S. Department of Veterans Affairs (VA)'s awards of disability for posttraumatic stress disorder (PTSD) to women. However, the diagnoses and opinions made by disability examiners have not been studied. A sample of 270 initial PTSD examination reports and corresponding VA decisions were studied. Compared to men, women veterans were as likely to be diagnosed with a service-related mental disorder, χ2 (1, N = 270) = 2.31, p =.129, odds ratio (OR) = 1.79, 95% CI [0.84, 3.80], and be granted service-connection, χ2 (1, N = 270) = 0.49, p =.483, OR = 1.28, 95% CI [0.65, 2.51]. Women veterans were considered to have more psychiatric symptoms, Z = -2.05, p =.041, r =.16, and more psychiatric impairment, Z = -2.48, p =.013, r =.20, but the percentage of disability awarded by the VA did not differ, χ2 (1, N = 270) = 0.49, p =.483; OR = 1.28, 95% CI [0.65, 2.51]. Secondary analyses implicate the role of military sexual trauma and premilitary trauma in explaining sex differences in symptoms and impairment. The findings indicate that neither opinions by examiners nor corresponding decisions by the VA regarding service connection reflect a negative bias toward women veterans. Results indicate that unbiased examinations lead to equitable VA claims decisions for women veterans. Future studies of the VA PTSD disability program nationally, including examination procedures and VA policies and implementation, will promote equity for women veterans in the PTSD claims process.

Data resource profile: nutrition data in the VA million veteran program.

The Department of Veterans Affairs (VA) Million Veteran Program (MVP) nutrition data is derived from dietary food/beverage intake information collected through a semiquantitative food frequency questionnaire (SFFQ). Estimates of dietary energy, nutrient, and non-nutritive food components intakes data were derived from an extensively validated SFFQ, which assessed the habitual frequency of consumption of 61 food items, added sugar, fried food frequency, and 21 nutritional supplements over the 12 months preceding questionnaire administration. Complete nutrition data was available for 353,418 MVP participants as of 30th September 2021. Overall, 91.5% of MVP participants with nutrition data were male with an average age of 65.7 years at enrollment. Participants who completed the SFFQ were primarily White (82.5%), and Blacks accounted for 13.2% of the responders. Mean ± SD energy intake for 353, 418 MVP participants was 1428 ± 616 kcal/day, which was 1434 ± 617 kcal/day for males and 1364 ± 601 kcal/day for females. Energy intake and information on 322 nutrients and non-nutritive food components is available through contact with MVP for research collaborations at www.research.va.gov/mvp. The energy and nutrient data derived from MVP SFFQ are an invaluable resource for Veteran health and research. In conjunction with the MVP Lifestyle Survey, electronic health records, and genomic data, MVP nutrition data may be used to assess nutritional status and related risk factors, disease prevalence, and determinants of health that can provide scientific support for the development of evidence-based public health policy and health promotion programs and services for Veterans and general population.

Propensity Score-Weighted Analysis of Postoperative Infection in Patients With and Without Preoperative Urine Culture

Although recent guidelines recommend against performance of preoperative urine culture before nongenitourinary surgery, many clinicians still order preoperative urine cultures and prescribe antibiotics for treatment of asymptomatic bacteriuria in an effort to reduce infection risk. To assess the association between preoperative urine culture testing and postoperative urinary tract infection (UTI) or surgical site infection (SSI), independent of baseline patient characteristics or type of surgery. This cohort study analyzed surgical procedures performed from January 1, 2017, to December 31, 2019, at any of 112 US Department of Veterans Affairs (VA) medical centers. The cohort comprised VA enrollees who underwent major elective noncardiac, nonurological operations. Machine learning and inverse probability of treatment weighting (IPTW) were used to balance the characteristics between those who did and did not undergo a urine culture. Data analyses were performed between January 2023 and January 2024. Performance of urine culture within 30 days prior to surgery. The 2 main outcomes were UTI and SSI occurring within 30 days after surgery. Weighted logistic regression was used to estimate odds ratios (ORs) for postoperative infection based on treatment status. A total of 250 389 VA enrollees who underwent 288 858 surgical procedures were included, with 88.9% (256 753) of surgical procedures received by males and 48.9% (141 340) received by patients 65 years or older. Baseline characteristics were well balanced among treatment groups after applying IPTW weights. Preoperative urine culture was performed for 10.5% of surgical procedures (30 384 of 288 858). The IPTW analysis found that preoperative urine culture was not associated with SSI (adjusted OR [AOR], 0.99; 95% CI, 0.90-1.10) or postoperative UTI (AOR, 1.18; 95% CI, 0.98-1.40). In analyses limited to orthopedic surgery and neurosurgery as a proxy for prosthetic implants, the adjusted risks for UTI and SSI were also not associated with preoperative urine culture performance. This cohort study found no association between performance of a preoperative urine culture and lower risk of postoperative UTI or SSI. The results support the deimplementation of urine cultures and associated antibiotic treatment prior to surgery, even when using prosthetic implants.

Multidisciplinary providers’ perceptions of care delivery for sleep disorders: A qualitative case study

ObjectivesSleep disorders are wide-ranging in their causes and impacts on other physical and mental health conditions. Thus, sleep disorders could benefit from a multidisciplinary approach to assessment and treatment. An integrated care model is often recommended but is costly to implement. We sought to understand how, in the absence of an established organizational structure for integrated sleep care, providers from different clinics work together to provide care for sleep disorders. MethodsA qualitative case study at one U.S. Department of Veterans Affairs (VA) medical center. We used a purposeful nested sampling strategy, combining maximum variation sampling and snowball sampling to recruit key staff involved in sleep care. ResultsWe interviewed providers (N = 10) from sleep medicine, primary care, and mental health services. Providers identified the ubiquity of sleep disorders and a concomitant need for multidisciplinary care. However, they described limited opportunities for multidisciplinary interactions and consequently a negative impact on clinical care. Providers described fragmentation in two areas: among sleep specialists and between sleep specialists and other referring and managing providers. ConclusionsA range of interventions, based on setting and resources, could improve care coordination both among sleep specialists and between sleep and nonsleep providers. While integrated sleep specialist clinics could reduce care fragmentation, they may not directly impact coordination with referring providers, like primary care and general mental health, who are essential in managing chronic conditions. Future work should continue to explore improving care coordination for sleep problems to ensure patients receive high-quality, timely, patient-centered care.
