RESUMO
We recently conducted an exploratory study that indicated that several direct-acting antivirals (DAAs), highly effective medications for hepatitis C virus (HCV) infection, were also associated with improvement in posttraumatic stress disorder (PTSD) among a national cohort of US Department of Veterans Affairs (VA) patients treated between October 1, 1999, and September 30, 2019. Limiting the same cohort to patients with PTSD and HCV, we compared the associations of individual DAAs with PTSD symptom improvement using propensity score weighting. After identifying patients who had available baseline and endpoint PTSD symptom data as measured with the PTSD Checklist (PCL), we compared changes over the 8-12 weeks of DAA treatment. The DAAs most prescribed in conjunction with PCL measurement were glecaprevir/pibrentasvir (GLE/PIB; n = 54), sofosbuvir/velpatasvir (SOF/VEL; n = 54), and ledipasvir/sofosbuvir (LDV/SOF; n = 145). GLE/PIB was superior to LDV/SOF, with a mean difference in improvement of 7.3 points on the PCL (95% confidence interval (CI): 1.1, 13.6). The mean differences in improvement on the PCL were smaller between GLE/PIB and SOF/VEL (3.0, 95% CI: -6.3, 12.2) and between SOF/VEL and LDV/SOF (4.4, 95% CI: -2.4, 11.2). While almost all patients were cured of HCV (92.5%) regardless of the agent received, PTSD outcomes were superior for those receiving GLE/PIB compared with those receiving LDV/SOF, indicating that GLE/PIB may merit further investigation as a potential PTSD treatment.

BACKGROUND: There is mixed evidence regarding the direction of a potential association between post-traumatic stress disorder (PTSD) and suicide mortality. AIMS: This is the first population-based study to account for both PTSD diagnosis and PTSD symptom severity simultaneously in the examination of suicide mortality. METHOD: Retrospective study that included all US Department of Veterans Affairs (VA) patients with a PTSD diagnosis and at least one symptom severity assessment using the PTSD Checklist (PCL) between 1 October 1999 and 31 December 2018 (n = 754 197). We performed multivariable proportional hazards regression models using exposure groups defined by level of PTSD symptom severity to estimate suicide mortality rates. For patients with multiple PCL scores, we performed additional models using exposure groups defined by level of change in PTSD symptom severity. We assessed suicide mortality using the VA/Department of Defense Mortality Data Repository. RESULTS: Any level of PTSD symptoms above the minimum threshold for symptomatic remission (i.e. PCL score >18) was associated with double the suicide mortality rate at 1 month after assessment. This relationship decreased over time but patients with moderate to high symptoms continued to have elevated suicide rates. Worsening PTSD symptoms were associated with a 25% higher long-term suicide mortality rate. Among patients with improved PTSD symptoms, those with symptomatic remission had a substantial and sustained reduction in the suicide rate compared with those without symptomatic remission (HR = 0.56; 95% CI 0.37-0.88). CONCLUSIONS: Ameliorating PTSD can reduce risk of suicide mortality, but patients must achieve symptomatic remission to attain this benefit.
RESUMO
There is an elevated risk of suicide among people living in rural areas, and the rural-urban disparity in death by suicide is growing in the general United States population. The department of Veterans Affairs (VA) implemented programs targeting rural health in 2007 and suicide prevention in 2008. Rural-urban differences in suicide rates among VA users have not been examined since 2010. We sought to understand whether the rural-urban disparity in suicide risk among VA users decreased during a time of contemporaneous VA efforts to improve access to mental health care for rural Veterans and to improve the effectiveness of mental health services at preventing suicide. We performed a retrospective cohort study examining differences in the raw and adjusted annual suicide rate among rural and urban VA users between 2003 and 2017. All VHA users 2003-2017. Descriptive statistics are presented for all VHA users in 2017. This includes 6,120,355 unique VA users, 32.0% (n = 1,955,935) of whom lived at a rural address. Raw rates of death by suicide were higher in rural VA users than urban VA users overall (33.3 vs. 29.1 deaths per 100,000 population) and across years, but the age, sex, and race-adjusted rates converged in 2005. White VA users had over triple the rate of death by suicide as black VA users, and lived disproportionally in rural areas. The rural-urban suicide disparity among VA users persists. However, the disparity appears to be driven by differences in the racial composition of rural and urban patients, which were not accounted for in prior studies.

Hispanic Veterans are the largest growing racial and ethnic minority group in the Veterans Health Administration (VA) system. Though recent research has found increasing suicide rates in this population and a growing rural-urban disparity, literature on core population characteristics remains sparse. We used extensive patient demographic and clinical data from VA's electronic medical record repository to examine geographic and longitudinal variation in Hispanic VA patients from 2001 to 2018. As the first such detailed characterization of this population, this study was largely descriptive in nature, and included heatmaps of Hispanic patient residence across rural and urban US counties, along with descriptive measures of patient characteristics by rurality, and first year of VA use. We found that Hispanic patients (n = 722,893) represented 5.2% of new VA users between 2001 and 2018, a proportion which grew nearly 90% from 4.0% (2001-2006) to 7.5% (2013-2018). Hispanic patients were largely White, male, under age 50, and had minimal illness or disability. The highest prevalence of Hispanic patients was in the Southwest US/Mexico border region, while the Midwest experienced the largest growth of Hispanic patients. Rural Hispanic patients were more likely to be older, male, and to live in areas characterized by small foreign-born populations and high socioeconomic deprivation. Compared with Hispanic patients entering the VA system in 2001-2006, patients in 2013-2018 were younger, more likely to be female, and to live in urban areas. These findings illustrate the wide range of demographic, clinical, and geographic experiences in the growing VA Hispanic population and demonstrate that culturally competent care for Hispanic Veterans must reflect their intra-ethnic diversity.

PURPOSE: Death by suicide is increasing more rapidly among Hispanics than non-Hispanics who use United States Department of Veterans Affairs (VA) health services, and the increase is most rapid among those living in rural areas. Our goal was to identify characteristics of rural Hispanic VA patients that contribute to this emerging disparity. METHODS: We linked electronic medical records from the VA, personnel data from the US Department of Defense, mortality data from the US National Death Index, and data on area characteristics from the US Census Bureau to examine suicide trends among Hispanic VA patients from 2005 through 2019. After identifying the strongest predictors of suicide in the rural and urban Hispanic populations, we examined how those characteristics changed over time. FINDINGS: Age and sex-adjusted suicide mortality rates were consistently higher for rural versus urban Hispanic patients beginning in 2012, with the most recent rolling 5-year average rates being 31.0 per 100,000 for rural compared to 20.3 per 100,000 for urban in 2019. Models to predict suicide had fair performance in the rural (accuracy = 0.62, 95% CI: 0.51, 0.73) and urban (accuracy = 0.67, 95% CI: 0.63, 0.70) groups. Mental health diagnoses were predictive of suicide among rural Hispanic patients, but there was no evidence that mental health diagnoses were increasing more rapidly in rural compared to urban patients. CONCLUSIONS: While we confirmed that there is a higher rate of death by suicide among rural Hispanic VA patients relative to their urban counterparts, we were unable to identify clear drivers of this finding.

PURPOSE: The United States Department of Veterans Affairs (VA) has gradually implemented policies to increase access to mental health care outside of VA medical centers. Most notably, this included requirements to offer mental health services at VA-administered community-based clinics in 2008 and increased access to VA-paid care in the community beginning in 2014. Our objective was to understand how mental health service use patterns changed for rural VA patients during this time. METHODS: We developed a longitudinal cohort of all rural patients who used VA services between 2002 and 2019 (N = 3,345,862). We examined individual, health care, and contextual predictors of mental health service use as well as modalities of mental health service use during policy-relevant time periods using descriptive statistics. FINDINGS: Access to mental health services increased with each policy change. The annual percentage of rural VA patients accessing mental health services increased from 11.4% in the earliest years (2002-2004) to 19.8% in the latest years (2017-2019). The most rapid period of increase followed a requirement for availability of mental health services at VA-administered community clinics. Increasing access to VA-paid care in the community had less effect. By the end of the evaluation, gaps remained in the delivery of care to elderly patients over the age of 75. CONCLUSIONS: Rural patients use mental health services when they become available. Access was the highest with a combination of changes to both delivery modalities and payment methods. Continued, and perhaps different efforts are required to address a persistent disparity for older patients.

OBJECTIVE: Patients who die by suicide are often seen in primary care settings in the weeks leading to their death. There has been little study of brief interventions to prevent suicide in these settings. METHOD: We conducted a virtual, pilot, randomized controlled trial of a brief suicide prevention strategy called Veterans Affairs Brief Intervention and Contact Program (VA BIC) in patients who presented to a primary care mental health walk-in clinic for a new mental health intake appointment and were at risk for suicide. Our primary aim was to assess feasibility. We measured our ability to recruit 20 patients. We measured the proportion of enrolled patients who completed all study assessments. We assessed adherence among patients assigned to VA BIC. RESULTS: Twenty patients were enrolled and 95% (N = 19) completed all study assessments. Among the 10 patients assigned to VA BIC, 90% (N = 9) of patients completed all required intervention visits, and 100% (N = 10) completed ≥70% of the required interventions visits. CONCLUSION: It is feasible to conduct a virtual trial of VA BIC in an integrated care setting. Future research should clarify the role of VA BIC as a suicide prevention strategy in integrated care settings using an adequately powered design. CLINICAL TRIAL REGISTRATION: NCT04054947.

BACKGROUND: Despite the prevalence and negative impact of posttraumatic stress disorder (PTSD), there are few medications approved by the U.S. Food and Drug Administration for treatment, and approved medications do not work well enough. We leveraged large-scale electronic health record data to identify existing medications that may be repurposed as PTSD treatments. METHODS: We constructed a mechanistic tree of all Food and Drug Administration-approved medications and used the tree-based scan statistic to identify medications associated with greater than expected levels of clinically meaningful improvement in PTSD symptoms using electronic health record data from the U.S. Department of Veterans Affairs. Our cohort included patients with a diagnosis of PTSD who had repeated symptom measurements using the PTSD Checklist over a 20-year period (N = 168,941). We calculated observed numbers based on patients taking each drug or mechanistically related class of drugs and the expected numbers based on the tree as a whole. RESULTS: Medications typically used to treat PTSD, such as the Food and Drug Administration-approved agent sertraline, were associated with improvement in PTSD symptoms, but the effects were small. Several, but not all, direct-acting antivirals used in the treatment of hepatitis C virus demonstrated a strong association with PTSD improvement. The finding was robust to a sensitivity analysis excluding patients who received established PTSD treatments, including trauma-focused psychotherapy, concurrent with hepatitis treatment. CONCLUSIONS: Our exploratory approach both demonstrated findings that are consistent with what is known about pharmacotherapy for PTSD and uncovered a novel class of medications that may improve PTSD symptoms.

INTRODUCTION: There is emerging evidence to support that the COVID-19 pandemic and related public health measures may be associated with negative mental health sequelae. Rural populations in particular may fair worse because they share many unique characteristics that may put them at higher risk for adverse outcomes with the pandemic. Yet, rural populations may also be more resilient due to increased sense of community. Little is known about the impact of the pandemic on the mental health and well-being of a rural population pre- and post-pandemic, especially those with serious mental illness. MATERIAL AND METHODS: We conducted a longitudinal, mixed-methods study with assessments preceding the pandemic (between October 2019 and March 2020) and during the stay-at-home orders (between April 23, 2020, and May 4, 2020). Changes in hopelessness, suicidal ideation, connectedness, and treatment engagement were assessed using a repeated-measures ANOVA or Friedman test. RESULTS: Among 17 eligible participants, 11 people were interviewed. Overall, there were no notable changes in any symptom scale in the first 3-5 months before the pandemic or during the stay-at-home orders. The few patients who reported worse symptoms were significantly older (mean age: 71.7 years, SD: 4.0). Most patients denied disruptions to treatment, and some perceived telepsychiatry as beneficial. CONCLUSIONS: Rural patients with serious mental illness may be fairly resilient in the face of the COVID-19 pandemic when they have access to treatment and supports. Longer-term outcomes are needed in rural patients with serious mental illness to better understand the impact of the pandemic on this population.

OBJECTIVE: To identify geographic variation in mental health service use in the Department of Veterans Affairs (VA), the authors constructed utilization-based VA mental health service areas (MHSAs) for outpatient treatment and mental health referral regions (MHRRs) for residential and acute inpatient treatment. METHODS: MHSAs are empirically derived geographic groupings of one or more counties containing one or more VA outpatient mental health clinics. For each county within an MHSA, patients received most of their VA-provided outpatient mental health care within that MHSA. MHSAs were aggregated into MHRRs according to where VA users in each MHSA received most of their residential and acute inpatient mental health care. Attribution loyalty was evaluated with the localization index-the fraction of VA users living in each geographic area who used their designated MHSA and MHRR facility. Variation in outpatient mental health visits and in acute inpatient and residential mental health stays was determined for the 2008-2018 period. RESULTS: A total of 441 MHSAs were aggregated to 115 MHRRs (representing 3,909,080 patients with 52,372,303 outpatient mental health visits). The mean±SD localization index was 59.3%±16.4% for MHSAs and 67.8%±12.7% for MHRRs. Adjusted outpatient mental health visits varied from a mean of 0.88 per year in the lowest quintile of MHSAs to 3.14 in the highest. Combined residential and acute inpatient days varied from 0.29 to 1.79 between the lowest and highest quintiles. CONCLUSIONS: MHSAs and MHRRs validly represented mental health utilization patterns in the VA and displayed considerable variation in mental health service provision across different locations.

OBJECTIVE: Risk for suicide is high after psychiatric hospitalization. The World Health Organization's Brief Intervention and Contact (BIC) program has shown efficacy in preventing suicide. A version adapted for the U.S. Department of Veterans Affairs (VA) was studied to determine preliminary effects. METHODS: Patients receiving psychiatric hospitalization because of acute risk for self-harm were randomly assigned to the VA BIC or standard care alone. Effect sizes (Hedges' g) for suicidal ideation (primary outcome), social connectedness (measured as thwarted belongingness and perceived burdensomeness), hopelessness, and engagement were calculated at 1 and 3 months. RESULTS: Patients were randomly assigned to the VA BIC (N=10) or standard care (N=9). The VA BIC had a medium or large effect on most measures at 1 month (suicidal ideation, g=0.45). Effects diminished at 3 months, except for thwarted belongingness (g=0.81). CONCLUSIONS: The VA BIC had meaningful effects on suicide-related outcomes. The largest effect was seen in the first month.

INTRODUCTION: Published research indicates that posttraumatic stress disorder (PTSD) is associated with increased mortality. However, causes of death among treatment-seeking patients with PTSD remain poorly characterized. The study objective was to describe causes of death among Veterans with PTSD to inform preventive interventions for this treatment population. METHODS: A retrospective cohort study was conducted for all Veterans who initiated PTSD treatment at any Department of Veterans Affairs Medical Center from fiscal year 2008 to 2013. The primary outcome was mortality within the first year after treatment initiation. In 2018, collected data were analyzed to determine leading causes of death. For the top ten causes, standardized mortality ratios (SMRs) were calculated from age- and sex-matched mortality tables of the U.S. general population. RESULTS: A total of 491,040 Veterans were identified who initiated PTSD treatment. Mean age was 48.5 (±16.0) years, 90.7% were male, and 63.5% were of white race. In the year following treatment initiation, 1.1% (5,215/491,040) died. All-cause mortality was significantly higher for Veterans with PTSD compared with the U.S. population (SMR=1.05, 95% CI=1.02, 1.08, p<0.001). Veterans with PTSD had a significant increase in mortality from suicide (SMR=2.52, 95% CI=2.24, 2.82, p<0.001), accidental injury (SMR=1.99, 95% CI=1.83, 2.16, p<0.001), and viral hepatitis (SMR=2.26, 95% CI=1.68, 2.93, p<0.001) versus the U.S. POPULATION: Of those dying from accidental injury, more than half died of poisoning (52.3%, 325/622). CONCLUSIONS: Veterans with PTSD have an elevated risk of death from suicide, accidental injury, and viral hepatitis. Preventive interventions should target these important causes of death.
