Quality of telehealth-provided cancer care in VA.

1633 Background: As the largest integrated health care system in the United States, the Veterans Health Administration (VA) has extensive experience in utilizing telehealth-(TH) to deliver care to the 10 million enrolled Veterans, including the~50,000 patients newly diagnosed with cancer annually and ~500,000 cancer survivors. The VA National TeleOncology (NTO) service was established in 2020 to provide specialized treatment regardless of geographical location. We sought to compare quality in TH-delivered care compared to traditional (TR) in-person VA care. Methods: Using the VA EHR, we identified patients who had an ICD-10 diagnostic code for an incident malignancy from Dec 2016 to March 2021 at three medical centers providing both TR and TH care. We used EHR review to classify patients as TH users, if they received TH services at least once for their cancer care, or TR care if no telehealth was used. Using both structured EHR data and manual review by two trained abstractors, we gathered demographic, clinical, and treatment characteristics to calculate 25 Quality Oncology Practice Initiative (QOPI) measures in the domains of symptoms and toxicity management (2), end of life and palliative care (10), and core measures (13). We report QOPI measures descriptively; and used chi-squared tests with alpha = 0.05 to compare TH and TR. Results: We identified 972 patients with lymphoma, prostate, lung or colorectal cancer. 427 (44%) were TH users and 545 (56%) were TR, and they were predominately white (n=819, 84.3%) men (n=930, 95.7%). TH users had better (n=13), worse (n=9), same (n=2) and unevaluable (n=1) descriptive performance on measures. For example, TH and TR were similar in administration of appropriate antiemetic therapy for high and moderate-risk antineoplastic agents (44.8% vs 42.4%). TH performed better than TR for chemotherapy summary being completed within three months of chemotherapy ending (83.4% vs 75.6%) and for emotional well-being being assessed by the second office visit (92.3% vs 89.9%). Appropriate tobacco use cessation administration within the previous year was statistically higher in TH (85.3% vs 76.2% p=0.0021). No differences were statistically significant for any other QOPI measures. Conclusions: VA is a leader in TH cancer care because of both its volume and quality. VA-provided TH cancer care quality is similar to or better than that of TR in-person care. NTO specifically, and VA teleoncology broadly, provides another option to Veterans for cancer care.

“It Feels Like Health Care with the Patient in Mind”: VA Patient and Staff Perspectives on Self-Collected HPV Testing

PurposeSelf-collected testing for human papillomavirus (HPV) is poised to transform cervical cancer screening. Self-tests demonstrate similar accuracy to clinician-collected tests, but for the half a million women served by the Veterans Health Administration (VA) and their clinicians, self-collected cervical cancer screening would be a new practice. We examined VA patient and staff perspectives to inform future implementation. MethodsSemi-structured telephone interviews were conducted between 2021 and 2022 with female veterans receiving VA care (n = 22) and VA women's health nurses, clinicians, and administrators (n = 27). Interviews were audio-recorded and transcribed. Interview questions addressed knowledge and interest, potential advantages or disadvantages, and any questions participants had about self-collected screening. Responses were analyzed using rapid qualitative methods. Main findingsFive overarching themes were identified. Both patients and staff indicated high interest and enthusiasm for self-collected HPV testing, tempered by questions about test accuracy and logistical considerations. Familiarity with self-testing for other conditions such as colon-cancer screening or COVID made self-collection seem like a simple, convenient option. However, self-testing was not viewed as a good fit for all patients, and concerns about lost opportunities or missed incidental lesions were raised. Patients and staff described challenges with pelvic examinations for patients with past sexual trauma, particularly in the male-dominated VA environment. Pelvic exams can leave patients feeling vulnerable and exposed; self-collected testing was seen as a mechanism for patient empowerment. Principal conclusionsVeteran patients and VA staff shared common perspectives about potential advantages and disadvantages of self-collected HPV testing. Self-collected HPV testing has the potential to improve trauma-informed preventive health care for veterans.

"You want people to listen to you": Patient experiences of women's healthcare within the Veterans Health Administration.

To identify constructs that are critical in shaping Veterans' experiences with Veterans Health Administration (VA) women's healthcare, including any which have been underexplored or are not included in current VA surveys of patient experience. From June 2022 to January 2023, we conducted 28 semi-structured interviews with a diverse, national sample of Veterans who use VA women's healthcare. Using VA data, we divided Veteran VA-users identified as female into four groups stratified by age (dichotomized at age 45) and race/ethnicity (non-Hispanic White vs. all other). We enrolled Veterans continuously from each recruitment strata until thematic saturation was reached. For this qualitative study, we asked Veterans about past VA healthcare experiences. Interview questions were guided by a priori domains identified from review of the literature, including trust, safety, respect, privacy, communication and discrimination. Analysis occurred concurrently with interviews, using inductive and deductive content analysis. We identified five themes influencing Veterans' experiences of VA women's healthcare: feeling valued and supported, bodily autonomy, discrimination, past military experiences and trauma, and accessible care. Each emergent theme was associated with multiple of the a priori domains we asked about in the interview guide. Our findings underscore the need for a measure of patient experience tailored to VA women's healthcare. Existing patient experience measures used within VA fail to address several aspects of experience highlighted by our study, including bodily autonomy, the influence of past military experiences and trauma on healthcare, and discrimination. Understanding distinct factors that influence women and gender-diverse Veterans' experiences with VA care is critical to advance efforts by VA to measure and improve the quality and equity of care for all Veterans.

Examining the Veterans Health Administration whole health model of care within the context of posttraumatic stress disorder.

The Veterans Health Administration's Whole Health system of care focuses on offering veterans holistic health approaches and tailoring health care to individual's goals and preferences. The present study assessed factors associated with Whole Health use and its potential benefits among veterans with posttraumatic stress disorder (PTSD) receiving Veterans Health Administration care. This cohort study used retrospective electronic health records combined with survey data (baseline, 6 months) from 18 Veterans Affairs Whole Health pilot implementation sites and compared patient-reported outcomes between veterans who used Whole Health services versus those who did not, among veterans with (n = 1,326) and without (n = 3,243) PTSD. Patient-reported outcomes assessed were pain (PEG), patient-reported outcomes measurement information system physical and mental health functioning, and a one-item global meaning and purpose assessment. Veterans with PTSD were more likely to have used Whole Health (38% vs. 21%) than those without PTSD. Veterans with PTSD who used Whole Health services experienced small improvements over 6 months in physical (Cohen's d = .12) and mental (Cohen's d = .15) health functioning. Veterans without PTSD who used Whole Health services experienced small improvements in physical health (Cohen's d = .09) but not mental health (Cohen's d = .04). Veterans with PTSD were frequently connected with Whole Health services even though implementation efforts were not explicitly focused on reaching this population. Results suggest Whole Health may play an important role in how veterans with PTSD engage with health care. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Perspectives on supporting Veterans’ social needs during hospital to home health transitions: findings from the Transitions Nurse Program

BackgroundVeterans who need post-acute home health care (HHC) are at risk for adverse outcomes and unmet social needs. Veterans’ social needs could be identified and met by community-based HHC clinicians due to their unique perspective from the home environment, acuity of Veterans they serve, and access to Veterans receiving community care. To understand these needs, we explored clinician, Veteran, and care partner perspectives to understand Veterans’ social needs during the transition from hospital to home with skilled HHC.MethodsQualitative data were collected through individual interviews with Veterans Health Administration (VHA) inpatient & community HHC clinicians, Veterans, and care partners who have significant roles facilitating Veterans’ hospital to home with HHC transition. To inform implementation of a care coordination quality improvement intervention, participants were asked about VHA and HHC care coordination and Veterans’ social needs during these transitions. Interviews were recorded, transcribed, and analyzed inductively using thematic analysis and results were organized deductively according to relevant transitional care domains (Discharge Planning, Transition to Home, and HHC Delivery).ResultsWe conducted 35 interviews at 4 VHA Medical Centers located in Western, Midwestern, and Southern U.S. regions during March 2021 through July 2022. We organized results by the three care transition domains and related themes by VHA, HHC, or Veteran/care partner perspective. Our themes included (1) how social needs affected access to HHC, (2) the need for social needs screening during hospitalization, (3) delays in HHC for Veterans discharged from community hospitals, and (4) a need for closed-loop communication between VHA and HHC to report social needs.ConclusionsHHC is an underexplored space for Veterans social needs detection. While this research is preliminary, we recommend two steps forward from this work: (1) develop closed-loop communication and education pathways with HHC and (2) develop a partnership to integrate a social risk screener into HHC pathways.

Development and Validation of a Measure to Assess Patient Experiences With Video Care Encounters

As video-based care expands in many clinical settings, assessing patient experiences with this care modality will help optimize health care quality, safety, and communication. To develop and assess the psychometric properties of the video visit user experience (VVUE) measure, a patient-reported measure of experiences with video-based technology. In this survey study, veterans completed a web-based, mail, or telephone survey about their use of Veterans Healthcare Administration (VHA) virtual care between September 2021 and January 2022. The survey was completed by patients who reported having a VHA video visit on their own device or a VHA-issued device and linked to VHA utilization data for the 6 months following the survey. Data analysis was performed from March 2022 to February 2023. The survey included 19 items about experiences with video visits that were rated using a 4-point Likert-type scale (strongly disagree to strongly agree). First, an exploratory factor analysis was conducted to determine the factor structure and parsimonious set of items, using the McDonald Omega test to assess internal consistency reliability. Then, a confirmatory factor analysis was conducted to test structural validity, and bivariate correlations between VVUE and VHA health care engagement were calculated to test concurrent validity. Finally, predictive validity was assessed using logistic regression to determine whether VVUE was associated with future VHA video visit use. Among 1887 respondents included in the analyses, 83.2% (95% CI, 81.5%-84.8%) were male, 41.0% (95% CI, 38.8%-43.1%) were aged 65 years or older, and the majority had multiple chronic medical and mental health conditions. The exploratory factor analysis identified a 10-item single-factor VVUE measure (including questions about satisfaction, user-centeredness, technical quality, usefulness, and appropriateness), explaining 96% of the total variance, with acceptable internal consistency reliability (ω = 0.95). The confirmatory factor analysis results confirmed a single-factor solution (standardized root mean squared residual = 0.04). VVUE was positively associated with VHA health care engagement (ρ = 0.47; P < .001). Predictive validity models demonstrated that higher VVUE measure scores were associated with future use of video visits, where each 1-point increase on VVUE was associated with greater likelihood of having a video visit in subsequent 6 months (adjusted odds ratio, 1.04; 95% CI, 1.02-1.06). The findings of this study of veterans using video visits suggest that a brief measure is valid to capture veterans' experiences receiving VHA virtual care.

Informational letters or postcards to initiate remote monitoring among veterans with pacemakers and implantable cardioverter-defibrillators: A randomized, controlled trial.

Remote monitoring (RM) of pacemakers and implantable cardioverter-defibrillators (ICDs) is a Class 1, Level of Evidence A recommendation because of its multitude of clinical benefits. However, RM adherence rates are suboptimal, precluding patients from achieving these benefits. There is a need for direct-to-patient efforts to improve adherence. In this national randomized, controlled trial conducted in the Veterans Health Administration (VHA), 2120 patients with a pacemaker or ICD who had not sent an RM transmission for ≥1 year (and usually ≥3 years) while under VHA care for their device were randomly assigned to be mailed a postcard (n=1076) or a detailed letter (n=1044). The postcard described what RM does and its key benefits (reduced mortality and fewer in-person visits). The letter provided a similar message but included more details about RM benefits and the process. The primary outcome was an RM transmission sent within 90 days of mailing, and a secondary outcome was an RM transmission sent within 365 days. The primary outcome was achieved in 121 (11.3%) in the postcard and 96 patients (9.2%) in the letter group (p=.12). The secondary outcome was achieved in 266 (24.7%) and 239 (22.9%), respectively (p=.32). This randomized trial showed no significant difference in the proportion of chronically non-adherent patients who sent an RM transmission after receiving a low-cost postcard or a detailed, higher-cost letter encouraging their participation in RM. However, as only a minority of patients responded to either, further work is needed to engage patients in the life-saving benefits of RM.

Alcohol-Related Care Among Veterans With Unhealthy Alcohol Use: The Role of Long-Term Opioid Therapy Receipt.

Long-term opioid therapy (LTOT) is potentially dangerous among patients with unhealthy alcohol use because of possible adverse interactions. We examined receipt of alcohol-related care among patients with unhealthy alcohol use receiving LTOT and without opioid receipt. We use data collected from 2009 to 2017 in the Women Veterans Cohort Study, a national cohort of Veterans engaged in Veterans Health Administration care. We included patients who screened positive for unhealthy alcohol use (score ≥5) using the Alcohol Use Disorder Identification Consumption questionnaire. Our primary exposure was LTOT (receipt of prescribed opioids for ≥90 days) versus no opioid receipt at the time of the first positive Alcohol Use Disorder Identification Consumption. Our primary outcome was receipt of brief intervention within 14 days of positive alcohol screen. Unadjusted and 4 adjusted modified Poisson regression models assessed prevalence and relative rates (RRs) of outcomes. Among eligible veterans, 6222 of 113,628 (5.5%) received LTOT at screening. Among patients receiving LTOT, 67.5% (95% confidence interval [CI], 66.3%-68.6%) had a documented brief intervention within 14 days of positive screen, compared with 70.1% (95% CI, 69.8%-70.4%) among patients without opioid receipt (RR, 0.96; 95% CI, 0.95-0.98; P < 0.001). Within adjusted models, the rate of brief intervention among patients receiving LTOT remained lower than patients without opioid receipt. Among patients with unhealthy alcohol use, patients receiving LTOT had significantly lower rates of brief intervention receipt compared with those without opioid receipt, and they should be a focus for interventions to improve alcohol-related care and safer opioid prescribing.

Abstract P510: Trends in Statin Therapy for Primary Prevention Among Older Veterans, 2003-2020

Introduction: The burden and risk of atherosclerotic cardiovascular disease (ASCVD) in US Veterans is higher than the general population, yet rates of use of medications for primary prevention, specifically statins, are not well described. Since the early 2000s, trial data have proven the efficacy of statins for primary prevention, further encouraged by updated guidelines (notably 2001, 2013, 2018). Therefore, we sought to examine the proportion of older veterans free of ASCVD and trends of statin use for primary prevention within this cohort from 2003 to 2020. Methods: Study participants comprised all US Veterans ≥65 years, free of ASCVD, and with at least one visit in the Veteran’s Health Administration (VHA) in the year prior. Statin users had at least two or more prescriptions of any statin in each one-year period studied. VA prescription data were linked to Medicare/Medicaid to ensure complete capture of statin use. Descriptive statistics and crude proportions were calculated by year of study entry. Results: From 2003-2020, there were 5.1 million Veterans aged 65 and older who received regular care in VHA. The overall proportion of veterans free of ASCVD in that period was 60% (N=3,159,705). Statin prescriptions for primary prevention have increased from 39% in 2003 to 52% in 2020, remaining steady after 2007. For example, in 2011, 51% were prescribed statins, mean age 73±7, 87% white, 98% male, 82% hypertension, 37% diabetes, 94% hyperlipidemia; while in 2017, 53% were prescribed statins (age 72± 7, 80% white, 97% male, 73% hypertension, 31% diabetes, 74% hyperlipidemia), received statin therapy for primary prevention (Figure). Conclusion: A substantial proportion of Veterans ≥65 years were at risk for ASCVD. While statin prescriptions for primary prevention have increased from 2003-2020, over the past 15 years, they have remained at around 50%. These findings indicate a focus on primary prevention among older Veterans is needed.

Abstract P169: Cardiovascular Disease Incidence Among Male Veterans by Sexual Orientation and Race

Introduction: Studies of cardiovascular disease (CVD) in sexual minority (SM) men (i.e., gay, bisexual) vs. heterosexual men are limited by small sample sizes and lack of objective CVD ascertainment. Small samples also hinder study at the intersection of race and sexual orientation on CVD events. We used the Veterans Healthcare Administration Lesbian, Gay, Bisexual, Transgender Electronic Health Record cohort to fill these knowledge gaps. Methods: We studied 919,404 male cisgender veterans who were free of prevalent CVD and classified as SM or non-SM by a natural language processing tool. We defined incident CVD as first instance of AMI, ischemic stroke, cardiac revascularization, or CVD death between baseline and date of death or 8/31/22. We stratified sample statistics by SM status and race. We used Cox proportional hazards regression to assess the intersection of sexual orientation and race with incident CVD; we adjusted for Hispanic ethnicity and age. Based on the minority stress model, non-SM White men were the referent. Results: Within races, traditional CVD risk factors were similarly distributed by SM status but SM men had greater prevalence of stress-associated characteristics like substance use, depression, and anxiety. Heterosexual, gay, and bisexual Asian men had lower CVD risk than non-SM White men, while Black/African American and Multiracial men had persistently increased CVD risk ( Table ). White and American Native gay men had increased CVD risk vs. non-SM White men. With the exception of Asians, all unclassified SM men had increased CVD incidence vs. non-SM White men. Risk was highest in among Black or Multiracial SM men. Conclusion: This is one of the first studies to examine the intersection of sexual orientation and race on CVD risk in male veterans. CVD risk appears increased or decreased in certain racial groups regardless of sexual orientation but this is not always true and invites further study into the mechanisms by which stress results in inequitable CVD events across groups.

Rural Native Veterans' Perceptions of Care in the Context of Navigator Program Development.

American Indian and Alaska Natives serve in the military at one of the highest rates of all racial and ethnic groups. For Veterans, the already significant healthcare disparities Natives experience are aggravated by barriers to accessing care, care navigation, and coordination of health care within the Veterans Health Administration (VHA) between the VHA and tribal health systems. To mitigate these barriers, the VHA is developing a patient navigation program designed specifically for rural Native Veterans. We describe formative work aimed at understanding and addressing barriers to VHA care from the perspective of rural Native Veterans and those who facilitate their care. Thirty-four individuals participated in semi-structured interviews (22 Veterans, 6 family members, and 6 Veteran advocates) drawn from 9 tribal communities across the US. Participants described many barriers to using the VHA, including perceptions of care scarcity, long travel distances to the VHA, high travel costs, and bureaucratic barriers including poor customer service, scheduling issues, and long waits for appointments. Many Veterans preferred IHS/tribal health care over the VHA due to its proximity, simplicity, ease of use, and quality. Rural Native Veterans must see a clear benefit to using the VHA given the many obstacles to its use. Veteran recommendations for addressing barriers to VHA care within a navigation program include assistance enrolling in, scheduling, and navigating VHA systems; paperwork assistance; cost reimbursement; and care coordination with the IHS/tribal health care.

Behavioral weight management use in the Veterans Health Administration: Sociodemographic and health correlates

IntroductionOver 40 % of United States Veterans Health Administration (VHA) primary care patients have obesity. Few patients use VHA's flagship weight management program, MOVE! and there is little information on other behavioral weight management program use. MethodsThe national United States cohort included over 1.5 million primary care patients with obesity, age 18–79, based on VHA administrative data. Gender stratified multivariable logistic regression identified correlates of weight management use in the year after a patient's first primary care appointment (alpha of 0.05). Weight management use was defined as MOVE! or nutrition clinic visits. ResultsThe cohort included 121,235 women and 1,521,547 men with 13 % and 7 % using weight management, respectively. Point estimates for specific correlates of use were similar between women and men, and across programs. Black patients were more likely to use weight management than White patients. Several physical and mental health diagnoses were also associated with increased use, such as sleep apnea and eating disorders. Age and distance from VHA were negatively associated with weight management use. ConclusionsWhen assessing multiple types of weight management visits, weight management care in VHA appears to be used more often by some populations at higher risk for obesity. Other groups may need additional outreach, such as those living far from VHA. Future work should focus on outreach and prevention efforts to increase overall use rates. This work could also examine the benefits of tailoring care for populations in greatest need.

Recruitment tools for transgender and gender diverse veterans in health care research.

Transgender and gender diverse (TGD) veterans in the Veterans Health Administration experience health and health care disparities, and research with this population is needed to improve gender-affirming care in Veterans Health Administration. However, TGD veterans may experience hesitancy to participate in research. We must address barriers to participation through feasible and acceptable methods. Opt-out letters are an effective tool used to recruit veterans in mental health research. The present study examined the feasibility and acceptability of opt-out letters modified for TGD veterans. Opt-out letters were sent to 54 potential TGD participants at three sites. The letters stated the research team would begin contacting veterans by phone in 2 weeks if they did not opt out of being contacted. Feasibility was measured through response rate. Acceptability was assessed through qualitative template analysis of interview data. Of the 54 potential participants, two opted out, three letters were undeliverable, and eight veterans called to opt in. Veterans reported that they found the letters to be clear and useful. The responses to the opt-out letters resulted in completing recruitment for two of the three sites. The research team then called the veterans who received the letter at the third site (three veterans) and recruited one additional veteran, for a total of nine TGD veterans. Opt-out letters may be a helpful tool to recruit TGD veterans to participate in research. Although these letters were designed to opt out, 89% of participants called the research team to opt in.

Predictors of non-fatal suicide attempts among Veterans Health Administration (VHA) patients who experienced military sexual trauma.

Military sexual trauma (MST) has been identified as a risk factor for suicidal behavior. To inform suicide prevention efforts within the Veterans Health Administration (VHA), this study evaluates predictors of non-fatal suicide attempts (NFSAs) among VHA patients who experienced MST. For VHA patients in fiscal year (FY) 2019 who previously screened positive for a history of MST, documented NFSAs were assessed. Using multivariable logistic regression, demographic, clinical, and VHA care utilization predictors of NFSAs were assessed. Of the 212,215 VHA patients who screened positive for MST prior to FY 2019 and for whom complete race, service connection, and rurality information was available, 1742 (0.8%) had a documented NFSA in FY 2019. In multivariable logistic regression analyses, total physical and mental health morbidities were not associated with NFSA risk. Predictors of a documented NFSA included specific mental health diagnoses [adjusted odds ratio (aOR) range: 1.28-1.94], receipt of psychotropic medication prescriptions (aOR range: 1.23-2.69) and having a prior year emergency department visit (aOR = 1.32) or inpatient psychiatric admission (aOR = 2.15). Among VHA patients who experienced MST, specific mental health conditions may increase risk of NFSAs, even after adjustment for overall mental health morbidity. Additionally, indicators of severity of mental health difficulties such as receipt of psychotropic medication prescriptions and inpatient psychiatric admissions are also associated with increased risk above and beyond risk associated with diagnoses. Findings highlight targets for suicide prevention initiatives among this vulnerable group within VHA and may help identify patients who would benefit from additional support.

Health Equity in the Veterans Health Administration From Veterans’ Perspectives by Race and Sex

Advancing equitable patient-centered care in the Veterans Health Administration (VHA) requires understanding the differential experiences of unique patient groups. To inform a comprehensive strategy for improving VHA health equity through the comparative qualitative analysis of care experiences at the VHA among veterans of Black and White race and male and female sex. This qualitative study used a technique termed freelisting, an anthropologic technique eliciting responses in list form, at an urban academic VHA medical center from August 2, 2021, to February 9, 2022. Participants included veterans with chronic hypertension. The length of individual lists, item order in those lists, and item frequency across lists were used to calculate a salience score for each item, allowing comparison of salient words and topics within and across different groups. Participants were asked about current perceptions of VHA care, challenges in the past year, virtual care, suggestions for change, and experiences of racism. Data were analyzed from February 10 through September 30, 2022. The Smith salience index, which measures the frequency and rank of each word or phrase, was calculated for each group. Responses from 49 veterans (12 Black men, 12 Black women, 12 White men, and 13 White women) were compared by race (24 Black and 25 White) and sex (24 men and 25 women). The mean (SD) age was 64.5 (9.2) years. Some positive items were salient across race and sex, including "good medical care" and telehealth as a "comfortable/great option," as were some negative items, including "long waits/delays in getting care," "transportation/traffic challenges," and "anxiety/stress/fear." Reporting "no impact" of racism on experiences of VHA health care was salient across race and sex; however, reports of race-related unprofessional treatment and active avoidance of race-related conflict differed by race (present among Black and not White participants). Experiences of interpersonal interactions also diverged. "Impersonal/cursory" telehealth experiences and the need for "more personal/attentive" care were salient among women and Black participants, but not men or White participants, who associated VHA care with courtesy and respect. In this qualitative freelist study of veteran experiences, divergent experiences of interpersonal care by race and sex provided insights for improving equitable, patient-centered VHA care. Future research and interventions could focus on identifying differences across broader categories both within and beyond race and sex and bolstering efforts to improve respect and personalized care to diverse veteran populations.

Identifying clinical phenotypes of frontotemporal dementia in post-9/11 era veterans using natural language processing.

Frontotemporal dementia (FTD) encompasses a clinically and pathologically diverse group of neurodegenerative disorders, yet little work has quantified the unique phenotypic clinical presentations of FTD among post-9/11 era veterans. To identify phenotypes of FTD using natural language processing (NLP) aided medical chart reviews of post-9/11 era U.S. military Veterans diagnosed with FTD in Veterans Health Administration care. A medical record chart review of clinician/provider notes was conducted using a Natural Language Processing (NLP) tool, which extracted features related to cognitive dysfunction. NLP features were further organized into seven Research Domain Criteria Initiative (RDoC) domains, which were clustered to identify distinct phenotypes. Veterans with FTD were more likely to have notes that reflected the RDoC domains, with cognitive and positive valence domains showing the greatest difference across groups. Clustering of domains identified three symptom phenotypes agnostic to time of an individual having FTD, categorized as Low (16.4%), Moderate (69.2%), and High (14.5%) distress. Comparison across distress groups showed significant differences in physical and psychological characteristics, particularly prior history of head injury, insomnia, cardiac issues, anxiety, and alcohol misuse. The clustering result within the FTD group demonstrated a phenotype variant that exhibited a combination of language and behavioral symptoms. This phenotype presented with manifestations indicative of both language-related impairments and behavioral changes, showcasing the coexistence of features from both domains within the same individual. This study suggests FTD also presents across a continuum of severity and symptom distress, both within and across variants. The intensity of distress evident in clinical notes tends to cluster with more co-occurring conditions. This examination of phenotypic heterogeneity in clinical notes indicates that sensitivity to FTD diagnosis may be correlated to overall symptom distress, and future work incorporating NLP and phenotyping may help promote strategies for early detection of FTD.

Combining Charlson comorbidity and VACS indices improves prognostic accuracy for all-cause mortality for patients with and without HIV in the Veterans Health Administration.

As people age with HIV (PWH), many comorbid diseases are more common than among age matched comparators without HIV (PWoH). While the Veterans Aging Cohort (VACS) Index 2.0 accurately predicts mortality in PWH using age and clinical biomarkers, the only included comorbidity is hepatitis C. We asked whether adding comorbid disease groupings from the Charlson Comorbidity Index (CCI) improves the accuracy of VACS Index. To maximize our ability to model mortality among older age groups, we began with PWoH in Veterans Health Administration (VA) from 2007-2017, divided into development and validation samples. Baseline predictors included age, and components of CCI and VACS Index (excluding CD4 count and HIV RNA). Patients were followed until December 31, 2021. We used Cox models to develop the VACS-CCI score and estimated mortality using a parametric (gamma) survival model. We compared accuracy using C-statistics and calibration curves in validation overall and within subgroups (gender, age </≥65 years, race/ethnicity, and CCI score). We then applied VACS-CCI in PWH and compared its accuracy to age, VACS Index 2.0, CCI and VACS-CCI with CD4 and HIV RNA added. The analytic sample consisted of 6,588,688 PWoH and 30,539 PWH. Among PWoH/PWH, median age was 65/55 years; 6%/3% were women; 15%/48% were Black and 5%/7% Hispanic. VACS-CCI provided the best discrimination (C-statistic = 0.81) with excellent calibration (predicted and observed mortality largely overlapped) overall and within subgroups. When VACS-CCI was applied to PWH it demonstrated similar discrimination as VACS Index 2.0 (C-statistic = 0.77 for both) but superior calibration among those with CD4 < 200. Discrimination was improved when CD4 and HIV RNA were added VACS-CCI (C-statistic = 0.79). Liver and kidney disease, congestive heart failure, malignancy, and dementia were negatively associated with CD4 (p-trends all <0.0001). Among PWH and PWoH in VA care, age alone weakly discriminates risk of mortality. VACS Index 2.0, CCI, and VACS-CCI all provide better discrimination, but VACS-CCI is more consistently calibrated. The association of comorbid diseases with lower CD4 underscores the likely role of HIV in non-AIDS conditions. Future work will include adding CD4 and HIV RNA to VACS-CCI and validating it in independent data.

Success of the US Veterans Health Administration's Hepatitis C Virus Care Continuum in the Direct-acting Antiviral Era.

Estimated hepatitis C prevalence within the Veterans Health Administration is higher than the general population and is a risk factor for advanced liver disease and subsequent complications. We describe the hepatitis C care continuum within the Veterans Health Administration 1 January 2014 to 31 December 2022. We included individuals in Veterans Health Administration care 2021-2022 who were eligible for direct-acting antiviral treatment 1 January 2014 to 31 December 2022. We evaluated the proportion of Veterans who progressed through each step of the hepatitis C care continuum, and identified factors associated with initiating direct-acting antivirals, achieving sustained virologic response, and repeat hepatitis C viremia. We identified 133 732 Veterans with hepatitis C viremia. Hepatitis C treatment was initiated in 107 134 (80.1%), with sustained virologic response achieved in 98 136 (91.6%). In those who achieved sustained virologic response, 1097 (1.1%) had repeat viremia and 579 (52.8%) were retreated for hepatitis C. Veterans of younger ages were less likely to initiate treatment and achieve sustained virologic response, and more likely to have repeat viremia. Stimulant use and unstable housing were negatively associated with each step of the hepatitis C care continuum. The Veterans Health Administration has treated 80% of Veterans with hepatitis C in care 2021-2022 and achieved sustained virologic response in more than 90% of those treated. Repeat viremia is rare and is associated with younger age, unstable housing, opioid use, and stimulant use. Ongoing efforts are needed to reach younger Veterans, and Veterans with unstable housing or substance use disorders.

Factors Associated with Veteran Self-Reported Use of Digital Health Devices

BackgroundDigital health devices (DHDs), technologies designed to gather, monitor, and sometimes share data about health-related behaviors or symptoms, can support the prevention or management of chronic conditions. DHDs range in complexity and utility, from tracking lifestyle behaviors (e.g., pedometer) to more sophisticated biometric data collection for disease self-management (e.g., glucometers). Despite these positive health benefits, supporting adoption and sustained use of DHDs remains a challenge.ObjectiveThis analysis examined the prevalence of, and factors associated with, DHD use within the Veterans Health Administration (VHA).DesignNational survey.ParticipantsVeterans who receive VHA care and are active secure messaging users.Main MeasuresDemographics, access to technology, perceptions of using health technologies, and use of lifestyle monitoring and self-management DHDs.ResultsAmong respondents, 87% were current or past users of at least one DHD, and 58% were provided a DHD by VHA. Respondents 65 + years were less likely to use a lifestyle monitoring device (AOR 0.57, 95% CI [0.39, 0.81], P = .002), but more likely to use a self-management device (AOR 1.69, 95% [1.10, 2.59], P = .016). Smartphone owners were more likely to use a lifestyle monitoring device (AOR 2.60, 95% CI [1.42, 4.75], P = .002) and a self-management device (AOR 1.83, 95% CI [1.04, 3.23], P = .037).ConclusionsThe current analysis describes the types of DHDs that are being adopted by Veterans and factors associated with their adoption. Results suggest that various factors influence adoption, including age, access to technology, and health status, and that these relationships may differ based on the functionalities of the device. VHA provision of devices was frequent among device users. Providing Veterans with DHDs and the training needed to use them may be important factors in facilitating device adoption. Taken together, this knowledge can inform future implementation efforts, and next steps to support patient-team decision making about DHD use.

Administration’s Share of Personnel in Veterans Health Administration and Private Sector Care

Health care administrative overhead is greater in the US than some other nations but has not been assessed in the Veterans Health Administration (VHA). To compare administrative staffing patterns in the VHA and private (non-VHA) sectors. This cross-sectional study was conducted using US employment data from 2019, prior to pandemic-related disruptions in health care staffing, and was carried out between January 14 and August 10, 2023. A nationally representative sample of federal and nonfederal personnel in hospitals and ambulatory care settings from the American Community Survey (ACS), all employees reported in VHA personnel records, and personnel in health insurance carriers and brokers tabulated by the Bureau of Labor Statistics (BLS) were analyzed. VHA vs private sector health care employment, including 397 occupations grouped into 18 categories. The proportion of staff working in administrative occupations. Among 3 239 553 persons surveyed in the ACS, 122 315 individuals (weighted population, 12 501 185 individuals) were civilians working in hospitals or ambulatory care; of the weighted population, 12 156 988 individuals (mean age, 42.6 years [95% CI, 42.5-42.7 years]; 76.2% [95% CI, 75.9%-76.5%] females) were private sector personnel and 344 197 individuals (mean age, 46.2 years [95% CI, 45.7-46.7 years]; 63.8% [95% CI, 61.8%-65.8%] females) were federal employees. In clinical settings, administrative occupations accounted for 23.4% (95% CI, 23.1%-23.8%) of private sector vs 19.8% (95% CI, 18.1%-21.4%) of VHA personnel. After including 1 000 800 employees at private sector health insurers and brokers and 13 956 VHA Central Office personnel with administrative occupations, administration accounted for 3 851 374 of 13 157 788 private sector employees (29.3%) vs 77 500 of 343 721 VHA employees (22.5%). Physicians represented approximately 7% of personnel in the VHA (7.2% [95% CI, 6.1%-8.2%]) and private sector (6.5% [95% CI, 6.3%-6.7%]), while the VHA deployed more registered nurses (23.7% [95% CI, 21.6%-25.8%] vs 21.2% [95% CI, 20.9%-21.5%]) and social service personnel (6.3% [95% CI, 5.4%-7.1%] vs 4.9% [95% CI, 4.7%-5.0%]) than the private sector. In this study, administrative occupations accounted for a smaller share of personnel in the VHA compared with private sector care, a difference possibly attributable to the VHA's simpler financing system. These findings suggest that if staffing patterns in the private sector mirrored those of the VHA, nearly 900 000 fewer administrative staff might be needed.
