The impact of alpha-1-adrenergic receptor antagonists on the progression of Parkinson disease

BackgroundAlpha-1-adrenergic receptor antagonists (AARAs) are used in the treatment of benign prostatic hypertrophy. Some AARAs, such as terazosin, stimulate glycolysis and increase cellular adenosine triphosphate levels through activation of phosphoglycerate kinase 1 (PGK1), which has been suggested to be of therapeutic benefit in patients with Parkinson disease (PD). ObjectiveThis study aimed to determine whether exposure to PGK1-activating AARAs was associated with slower PD progression. MethodsNational Veterans Affairs administrative data were used to identify patients who initiated PD-related pharmacotherapy during 2000 to 2019 and were concurrently prescribed an AARA. Using a retrospective cohort design, the count of incident PD-related outcome events within 1 year of follow-up was contrasted between patients prescribed a PGK1-activating AARA versus tamsulosin (an AARA without PKG1 stimulation), using multivariable negative binomial regression. PD-related outcome events were identified using ICD codes indicating motor symptoms, nonmotor symptoms, and other potential complications as clinical markers for the progression of PD. ResultsA total of 127,142 patients initiated drug therapy for PD during the observation period, of whom 24,539 concurrently received an AARA. Incident PD-related events were observed significantly less often in patients receiving a PGK1 AARA (n = 14,571) than tamsulosin (n = 9968) (incidence rate ratio [IRR] 0.80 [95% CI 0.77–0.83]). These results remained significant after adjustment for confounding factors (IRR 0.85 [95% CI 0.81–0.88]) and in sensitivity analyses. ConclusionPatients prescribed a PGK1-activating AARA experienced fewer PD-related outcome events than patients prescribed tamsulosin. These results may indicate a role for terazosin and other PGK1 activators in slowing disease progression of PD; however, randomized controlled trials are needed.

Intimate Partner Violence, Mental Health, and Aging-Related Health Among Men and Women Veterans Across the Lifespan.

A growing body of evidence suggests adverse health outcomes related to intimate partner violence (IPV), including traumatic brain injury (TBI). However, most research in this area has focused on reproductive-aged women. To examine relationships between IPV (with and without TBI), mental health, and aging-related health outcomes among men and women Veterans across the lifespan. Cross-sectional analysis of Department of Veterans Affairs (VA) administrative data from fiscal years 2000-2019. Descriptive statistics and chi-square analyses were used to compare key comorbidities in matched samples of Veterans with and without IPV (gender-stratified and matched 1:3 based on demographics and index date). Comparisons between those with IPV and TBI relative to IPV alone were also examined. Veterans aged 18 + with and without documented IPV in Department of Veterans Affairs (VA) electronic health records (n = 4108 men, 2824 women). ICD codes were used to identify IPV, TBI, and aging-related medical (sleep disorder, hypertension, diabetes, dementia) and common psychiatric (depression, posttraumatic stress disorder, alcohol use disorder, and substance use disorder) diagnoses. Demographic characteristics were reflective of VA-enrolled Veterans (men: mean age 66, SD 16; 72% non-Hispanic White; women: mean age 47, SD 13; 64% non-Hispanic White). Relative to Veterans without IPV, both men and women with IPV had higher rates of all examined medical (e.g., sleep disorders, men: 33% vs. 52%; women: 45% vs. 63%) and psychiatric diagnoses (e.g., depression, men 32% vs. 74%; women 59% vs. 91%; all ps < .001), with evidence of an additive effect of TBI on some psychiatric outcomes. IPV is broadly associated with aging-related and mental health, and TBI is a common correlate that may further contribute to psychiatric outcomes. Findings highlight the importance of trauma-informed care and recognizing the potential role of these exposures on men and women Veterans' health across the lifespan.

Using the RE-AIM framework to assess national teledermatology expansion.

Teledermatology has been utilized in the United States Department of Veterans Affairs (VA) for decades but continues to have incomplete penetration. VA has funded an initiative to enhance access to dermatology services since 2017 to support asynchronous teledermatology for Veterans living in rural areas. As part of an ongoing evaluation of this program, we assessed the teledermatology activity between the fiscal years 2020 and 2022. We focused on the second cohort of the initiative, comprising six VA facilities and their 54 referral clinics. We studied teledermatology programs at cohort facilities using the reach, effectiveness, adoption, implementation, and maintenance framework. We used a mixed-methods design including annual online reports completed by participating facilities and VA administrative data. When possible, we compared the data from the 3 years of teledermatology funding with the baseline year prior to the start of funding. Reach: Compared with the baseline year, there was a 100% increase in encounters and a 62% increase in patients seen at the funded facilities. Over 500 clinicians and support staff members were trained. Effectiveness: In FY 2022, primary or specialty care clinics affiliated with the funded facilities had more dermatology programs than primary or specialty care clinics across the VA (83% vs. 71% of sites). Adoption: By the end of the funding period, teledermatology constituted 16% of dermatology encounters at the funded facilities compared with 12% nationally. This reflected an increase from 9.2% at the funded facilities and 10.3% nationally prior to the funding period. Implementation: The continued funding for staff and equipment facilitated the expansion to rural areas. Maintenance: By the end of the funding period, all facilities indicated that they had fully implemented their program for patients of targeted primary care providers. The Program Sustainability Index scores generally increased during the funding period. Targeted funding to support asynchronous teledermatology implementation for rural Veterans increased its reach, adoption, and implementation, ultimately improving access. Providing program guidance with staffing and training resources can increase the impact of these programs. Ongoing efforts to maintain and increase communication between primary care and dermatology will be needed to sustain success.

Care Practices of Mental Health Clinical Pharmacist Practitioners Within an Interdisciplinary Primary Care Model for Patients With Substance Use Disorders.

Clinical pharmacist practitioners (CPPs) play an increasingly important role in interdisciplinary care for patients with substance use disorders (SUDs). However, CPPs' scope of practice varies substantially across clinics and settings. We sought to describe CPP practices and activities within an interdisciplinary, team-based primary care clinic dedicated to treat Veterans with histories of substance use disorders, experience of homelessness, high medical complexity, and other vulnerabilities. We conducted a retrospective cohort study of CPP activities using Department of Veterans Affairs (VA) administrative data in 2019. CPPs provided care for 228 patients, including 766 in-clinic visits, 341 telephone visits, and 626 chart reviews, with an average of 2.5 hours spent per patient per year. Patients seen by CPPs frequently experience mental health conditions and SUDs, including depression (66%), post-traumatic stress disorder (52%), opioid use disorder (OUD) (45%), and alcohol use disorder (44%). CPPs managed buprenorphine medications for OUD or chronic pain in 76 patients (33%). Most CPP interventions (3330 total) were for SUDs (33%), mental health conditions (24%), and pain management (24%), with SUD interventions including medication initiation, dose changes, discontinuations and monitoring. As part of opioid risk mitigation efforts, CPPs queried the state's prescription drug monitoring program 769 times and ordered 59 naloxone kits and 661 lab panels for empaneled patients. CPPs managed a high volume of vulnerable patients and provided complex care within an interdisciplinary primary care team. Similar CPP roles could be implemented in other primary care settings to increase access to SUD treatment.

The Effects of Suicide Exposure on Mental Health Outcomes Among Post-9/11 Veterans: Protocol for an Explanatory, Sequential, Mixed Methods Study.

The toll associated with suicide goes well beyond the individual who died. This study focuses on a risk factor for veteran suicide that has received little previous empirical attention-exposure to the suicide death of another person. The study's primary objective is to describe the mental health outcomes associated with suicide exposure among veterans who served on active duty after September 2001 ("post-9/11"). The secondary objective is to elucidate why some veterans develop persistent problems following suicide exposure, whereas others do not. This is an explanatory, sequential, mixed methods study of a nationally representative sample of post-9/11 veterans enrolled in Department of Veterans Affairs (VA) health care. Our sampling strategy was designed for adequate representation of female and American Indian and Alaska Native veterans to allow for examination of associations between suicide exposure and outcomes within these groups. Primary outcomes comprise mental health problems associated with trauma and loss (posttraumatic stress disorder and prolonged grief disorder) and suicide precursors (suicidal ideation, attempts, and planning). Data collection will be implemented in 3 waves. During wave 1, we will field a brief survey to a national probability sample to assess exposure history (suicide, other sudden death, or neither) and exposure characteristics (eg, closeness with the decedent) among 11,400 respondents. In wave 2, we will include 39.47% (4500/11,400) of the wave-1 respondents, stratified by exposure history (suicide, other sudden death, or neither), to assess health outcomes and other variables of interest. During wave 3, we will conduct interviews with a purposive subsample of 32 respondents exposed to suicide who differ in mental health outcomes. We will supplement the survey and interview data with VA administrative data identifying diagnoses, reported suicide attempts, and health care use. The study began on July 1, 2022, and will end on June 30, 2026. This is the only national, population-based study of suicide exposure in veterans and the first one designed to study differences based on sex and race. Comparing those exposed to suicide with those exposed to sudden death for reasons other than suicide (eg, combat) and those unexposed to any sudden death may allow for the identification of the common and unique contribution of suicide exposure to outcomes and help seeking. Integrating survey, qualitative, and VA administrative data to address significant knowledge gaps regarding the effects of suicide exposure in a national sample will lay the foundation for interventions to address the needs of individuals affected by a suicide death, including female and American Indian and Alaska Native veterans.

Does screening for PTSD lead to VA mental health care? Identifying the spectrum of initial VA screening actions.

Despite the active posttraumatic stress disorder (PTSD) screening program in Department of Veterans Affairs (VA) primary care clinics and the availability of empirically supported treatments for PTSD at VA, many veterans for whom screening suggests treatment may be indicated do not gain access to VA-based mental health care. To determine where we may be losing veterans to follow-up, we need to begin by identifying the initial action taken in response to a positive PTSD screen in primary care. Using VA administrative data and chart review, we identified the spectrum of initial actions taken after veterans screened positive for PTSD in VA primary care clinics nationwide between October 2017 and September 2018 (N = 41,570). We collapsed actions into those that could lead to VA-based mental health care (e.g., consult placed to a VA mental health clinic) versus not (e.g., veteran declined care), and then examined the association between these categories of actions and contextual- and individual-level variables. More than 61% of veterans with positive PTSD screens had evidence that an initial action toward VA-based mental health care was taken. Urban-dwelling and female veterans were significantly more likely to have evidence of these initial actions, whereas White and Vietnam-era veterans were significantly less likely to have this evidence. Our findings suggest that most veterans screening positive for PTSD in VA primary care clinics have evidence of initial actions taken toward VA-based mental health care; however, a substantial minority do not, making them unlikely to receive follow-up care. Findings highlight the potential benefit of targeted primary care-based access interventions. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The Impact of Comorbid Chronic Pain on Pharmacotherapy for Veterans with Post-Traumatic Stress Disorder.

Chronic pain can worsen PTSD symptomatology and may increase the risk of the prescription of multiple central nervous system (CNS)-active medications. The objective is to determine the impact of chronic pain on the number of CNS medications, including psychiatric medications, as well as the amount of medication changes. Veterans Affairs (VA) administrative data were used to identify VA-served Veterans with PTSD (N = 637,428) who had chronic pain (50.3%) and did not have chronic pain (49.7%) in 2020. The outcomes included the number of changes in psychiatric medications and the number of currently prescribed CNS-active mediations during a one-year observation period. The number of changes in psychiatric medications was significantly higher for those with chronic pain (mean (M) = 1.8) versus those without chronic pain (M = 1.6) (Z = 38.4, p < 0.001). The mean number of concurrent CNS-active medications were significantly higher for those with chronic pain (M = 2.7) versus those without chronic pain (M = 2.0) (Z = 179.7, p < 0.001). These differences persisted after adjustment for confounding factors using negative binomial regression. Veterans with comorbid chronic pain and PTSD are at increased risk for a higher number of medication changes and for receiving CNS-active polytherapy.

Exploring the importance of predisposing, enabling, and need factors for promoting Veteran engagement in mental health therapy for post-traumatic stress: a multiple methods study

PurposeThis study explored Veteran and family member perspectives on factors that drive post-traumatic stress disorder (PTSD) therapy engagement within constructs of the Andersen model of behavioral health service utilization. Despite efforts by the Department of Veterans Affairs (VA) to increase mental health care access, the proportion of Veterans with PTSD who engage in PTSD therapy remains low. Support for therapy from family members and friends could improve Veteran therapy use.MethodsWe applied a multiple methods approach using data from VA administrative data and semi-structured individual interviews with Veterans and their support partners who applied to the VA Caregiver Support Program. We integrated findings from a machine learning analysis of quantitative data with findings from a qualitative analysis of the semi-structured interviews.ResultsIn quantitative models, Veteran medical need for health care use most influenced treatment initiation and retention. However, qualitative data suggested mental health symptoms combined with positive Veteran and support partner treatment attitudes motivated treatment engagement. Veterans indicated their motivation to seek treatment increased when family members perceived treatment to be of high value. Veterans who experienced poor continuity of VA care, group, and virtual treatment modalities expressed less care satisfaction. Prior marital therapy use emerged as a potentially new facilitator of PTSD treatment engagement that warrants more exploration.ConclusionsOur multiple methods findings represent Veteran and support partner perspectives and show that amid Veteran and organizational barriers to care, attitudes and support of family members and friends still matter. Family-oriented services and intervention could be a gateway to increase Veteran PTSD therapy engagement.

Epidemiology and Psychiatric Correlates of Cancer among Homeless and Unstably Housed Veterans in the VA Health Care System.

This study examined the incidence and correlates of cancer among homeless and unstably housed (HUH) veterans as compared with stably housed (SH) veterans. Using Veterans Affairs (VA) administrative data from 564,563 HUH and 5,213,820 SH veterans in 2013 and 2014, we examined the types and stages of 69 different types of cancer diagnosed among HUH and SH veterans. Sociodemographic and psychiatric characteristics associated with cancer were also examined. The 1-year incidence rate of cancer was 21.5% lower among HUH veterans than SH veterans (0.68% and 0.86%, respectively). There was no difference in the most common stages and types of cancer among HUH and SH veterans. The most common primary sites of cancer were in the prostate, lung, and bronchus. HUH veterans were more likely than SH veterans to have cancer of the liver and intrahepatic bile ducts (∆4.79%). Among HUH veterans, older age and alcohol use disorder were associated with greater risk for any incident cancer while suicidal ideation/behaviors were associated with lower risk. Psychiatric conditions were often diagnosed before cancer diagnosis for SH and HUH veterans; rates of substance use disorders and suicidal ideation/behaviors decreased in HUH veterans after cancer diagnosis. The VA health care system serves many HUH veterans with cancer. Mental health and substance use disorders are important to treat in veterans at risk of cancer and as potential sequalae of cancer. The high prevalence of psychiatric disorders in HUH populations is important to consider in the diagnosis and treatment of cancer in these populations.

Supported Employment for Veterans with Traumatic Brain Injury History: Is it Working?

<h3>Research Objectives</h3> To examine characteristics and employment outcomes among Veterans with traumatic brain injury (TBI) history enrolled in Supported Employment. This program provides intense, individualized supported for individuals whose disabilities interfere with finding and maintaining employment. Supported Employment providers work closely with the Veteran's clinical treatment team, Veterans, and employers to ensure clinical and vocational supports are provided to facilitate workplace success. <h3>Design</h3> Review of Department of Veterans Affairs (VA) administrative and electronic medical record data collected between 2020-2022. <h3>Setting</h3> 12 VA medical centers. <h3>Participants</h3> Veterans with TBI history. <h3>Interventions</h3> Supported Employment. <h3>Main Outcome Measures</h3> Employment status. <h3>Results</h3> 92 Veterans with TBI history were referred to a VA Supported Employment program. They were primarily male (96%), White (74%), non-Hispanic (85%), Post-9/11 Veterans (59%) with an average age of 41 ± 10.4 years. The majority (83%) received VA service-connected disability compensation for up to 29 health conditions, and 30% were 100% service-connected. The majority were referred by the Polytrauma/TBI clinic (53%). At enrollment, they had been unemployed for 5 months (median). To date, half (51%) obtained at least 1 job within approximately 3 months (median = 97 days) of Supported Employment program entry. Incarceration history, current homelessness, and level of service-connected disability rating did not differ among Veterans who did or did not obtain employment (all ps > .05). <h3>Conclusions</h3> The majority of Veterans with TBI history and co-occurring military-related health conditions have demonstrated success in obtaining employment within a relatively short amount of time following enrollment in a Supported Employment program. Health and psychosocial factors that may be barriers to employment were not associated with obtaining a job, underscoring the effectiveness of Supported Employment services for Veterans with TBI history who may otherwise have employment challenges. <h3>Author(s) Disclosures</h3> The authors have no conflicts to declare.

Uterine Weight as a Modifier of Black/White Racial Disparities in Minimally Invasive Hysterectomy Among Veterans with Fibroids in the Veterans Health Administration.

Uterine fibroids are the most common indication for hysterectomy. Minimally invasive hysterectomy (MIH) confers lower risk of complications and shorter recovery than open surgical procedures; however, it is more challenging to perform with larger fibroids. There are racialized differences in fibroid size and MIH rates. We examined the role of uterine size in black-white differences in MIH among Veterans in the Department of Veterans Affairs (VA). Using VA clinical and administrative data, we conducted a cross-sectional study among black and white Veterans with fibroids who underwent hysterectomy between 2012 and 2014. We abstracted postoperative uterine weight from pathology reports as a proxy for uterine size. We used a generalized linear model to estimate the association between race and MIH and tested an interaction between race and postoperative uterine weight (≤250 g vs. >250 g). We estimated adjusted marginal effects for racial differences in MIH by postoperative uterine weight. The sample included 732 Veterans (60% black, 40% white). Postoperative uterine weight modified the association of race and MIH (p for interaction=0.05). Black Veterans with postoperative uterine weight ≤250 g had a nearly 12-percentage point decrease in MIH compared to white Veterans (95% CI -23.1 to -0.5), with no difference by race among those with postoperative uterine weight >250 g. The racial disparity among Veterans with small fibroids who should be candidates for MIH underscores the role of other determinants beyond uterine size. To eliminate disparities in MIH, research focused on experiences of black Veterans, including pathways to treatment and provider-patient interactions, is needed.

Assessment of modifications to evidence-based psychotherapies using administrative and chart note data from the US department of veterans affairs health care system.

The US Department of Veterans Affairs (VA) has over 15 years of experience in delivery of evidence-based psychotherapies (EBPs). This paper describes strategies for using clinical documentation and administrative data to understand adherence and modifications to EBPs for Posttraumatic Stress Disorder (PTSD). This study focused on two EBPs for PTSD, Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE). The sample included VA therapists from across the US who provided CPT and PE and the patients they treated over a 1-year period. The data sources for this study were templated EBP chart notes and VA administrative data. We used a manual review of note content and administrative data rules to code therapy adherence and modifications in 7,297 EBP sessions for 1,257 patients seen by 182 therapists. Two trained coders rated each therapy note and resolved discrepancies through consensus. To contextualize and explain variation in adherence and modifications, we conducted brief 30-45-min semi-structured interviews with a purposive subsample of these therapists (n = 32). Combining manual chart review and administrative data allowed for identification of 11 types of modifications. Raters disagreed on adherence for 30% of notes. The disagreement stemmed from the presence of therapy modifications that were not clearly documented, necessitating the development of decision rules and strategies for modification coding. Both therapists and patients contributed to the variance in the extent to which different modifications occurred. Therapist interviews demonstrated therapist awareness of modifying the protocols in the ways identified through chart review. Healthcare systems can use data collected as part of routine care to understand how and when EBPs are modified but need to develop scalable strategies to document adaptations and modifications to EBPs in routine care.

Medicaid Expansion and Veterans’ Reliance on the VA for Depression Care

In 2001, before the Affordable Care Act (ACA), some states expanded Medicaid coverage to include an array of mental health services, changing veterans' reliance on US Department of Veterans Affairs (VA) services. Using Medicaid and VA administrative data from 1999 to 2006, we used a difference-in-difference design to calculate shifts in veterans' reliance on the VA for depression care in New York and Arizona after the 2 states expanded Medicaid coverage to adults in 2001. Demographically matched, neighbor states Pennsylvania and New Mexico/Nevada were used as paired comparisons, respectively. Fractional logit was used to capture the distribution of inpatient and outpatient depression care utilization between the VA and Medicaid, while ordered logit and negative binomial regressions were applied to model Medicaid-VA dual users and per capita utilization of total depression care services, respectively. Medicaid expansion was associated with a 9.50 percentage point (pp) decrease (95% CI, -14.61 to -4.38) in reliance on the VA for inpatient depression care among service-connected veterans and a 13.37 pp decrease (95% CI, -21.12 to -5.61) among income-eligible veterans. For outpatient depression care, VA reliance decreased by 2.19 pp (95% CI, -3.46 to -0.93) among income-eligible veterans. Changes among service-connected veterans were nonsignificant (-0.60 pp; 95% CI, -1.40 to 0.21). After Medicaid expansion, veterans shifted depression care away from the VA, with effects varying by health care setting, income- vs service-related eligibility, and state of residence. Issues of overall cost, care coordination, and clinical outcomes deserve further study in the ACA era of Medicaid expansions.

Provider discussion of health goals and psychosocial needs: Comparing older to younger veteran experience.

To examine by age, the veterans' report on whether components of age-friendly health systems were discussed during primary care visits. Veterans Affairs (VA) Survey of Healthcare Experience of Patients from October 2015 to September 2019. Cross-sectional survey of VA users by age group (18-44 years, 45-64 years, 65+ years; N=1,042,318). We used weighted logistic regression models to evaluate disparities in whether veterans discussed with anyone in their provider's office: health goals, depression symptoms, stress, personal problems, and medications. Models were adjusted for socio-demographic characteristics (sex, socioeconomic status, education, rurality) and comorbidity. Surveys were administered by mail and online. Additional veteran characteristics were extracted from VA administrative data. In unadjusted analyses, VA users age 18-44 had a higher (-8.2%; CI: -9.0, -7.3) and users aged 45 to 64 had lower (4.0%; CI: 3.7, 4.3) predicted, probably discussing health goals compared to age 65+. Fewer VA users age 65+ reported discussing depression symptoms, personal problems, and stress than other age groups, whereas more VA users age 65+ discussed medications. Results were unchanged after adjusting for socio-demographics and comorbidity. Delivery of goal-concordant care relies on understanding the needs of individual patients. Lower rates of discussing what matters and mood represent potential missed opportunities to deliver age-friendly care for older veterans.

Predictors of discharge from the VA Caregiver Support Program.

The Department of Veterans Affairs (VA) Program of Comprehensive Assistance for Family Caregivers (PCAFC) is a clinical program providing training, a monthly stipend, and other services to caregivers of qualifying post-9/11 veterans with service-related injuries. Veteran-caregiver discharge from the program occurs when veteran recovery is achieved, participation is no longer in the veteran's best interest, or caregiving ceases. Public scrutiny about potentially inappropriate discharges resulted in a nationwide freeze on all discharges. PCAFC expanded to pre-9/11 veterans in October 2020; thus, lessons learned can continue to inform the expanded program. We pursued 3 objectives: (1) describe the discharge rate, reasons for discharge, and veteran and caregiver characteristics by discharge status; (2) identify factors associated with discharge from PCAFC nationally; and (3) characterize network variation in discharge predictors. Retrospective observational study using VA administrative data from fiscal year (FY) 2011 to FY 2017. Using multivariable Cox proportional hazards regression, we examined factors associated with PCAFC discharge among veterans and caregivers enrolled in PCAFC during FY 2011 to FY 2016. A total of 40.5% of all participants were discharged. Nonspouse caregivers and those applying in later years had the highest rates of discharge; spouse caregivers and those applying in earlier years had the lowest rates of discharge. In 4 of 18 networks, caregivers of Black veterans faced higher rates of discharge compared with caregivers of White veterans, and in 1 network, they faced lower rates of discharge. Substantial variability in rates of discharge was also observed across Veterans Integrated Service Networks. Training on clinically appropriate discharge criteria could improve practice and increase equity.

Musculoskeletal Conditions and Secondary Cardiovascular Morbidity Increase Veterans' Rehabilitation and Orthopaedic Service Utilization.

BackgroundMusculoskeletal conditions often affect patients’ mobility and ability to participate in health behaviors such as exercise, potentially affecting their systemic health. The purpose of this research is to determine how frequently cardiac-related comorbidities present in a veteran population with musculoskeletal service-connected disability and how this affects musculoskeletal health care utilization. MethodologyA retrospective cohort of Iraq and Afghanistan Veterans who received a Veterans Affairs (VA) disability determination for service-connected musculoskeletal disability were categorized according to the diagnosis of cardiac comorbidity including diabetes mellitus, hyperlipidemia, hypertension, and obesity, and atherosclerosis disease documented by ICD-9 codes in the VA administrative data. Among veterans with musculoskeletal service-connected disability, logistic regression was modeled to determine if musculoskeletal clinic utilization was associated with also having a cardiac comorbid condition. ResultsVeterans with musculoskeletal disability had a comorbid cardiac disorder 43% of the time. Post-traumatic arthritis was the only musculoskeletal condition positively associated with comorbid cardiac conditions. Veterans with comorbid cardiac diagnoses had 26-37% higher odds of receiving care by physical and occupational therapy, physical medicine, and orthopaedic surgery clinics compared to veterans without comorbid cardiac disease.ConclusionsVeterans in this cohort with musculoskeletal service-connected disability, plus cardiac conditions had greater clinic use for musculoskeletal and rehabilitation services compared to those without cardiac conditions. These results have implications for the rehabilitation and other health service needs of a new generation of veterans.

Gender differences in medication prescribing patterns for veterans with posttraumatic stress disorder: A 10-year follow-up study.

Women veterans with posttraumatic stress disorder (PTSD) have historically received more psychiatric medications than men. The current analysis identified prescribing trends of medications recommended for (i.e., select antidepressants) and against (i.e., benzodiazepines, select antidepressants, antipsychotics, and select anticonvulsants) use in PTSD treatment among women and men in 2010-2019. All veterans receiving care for PTSD in 2019 were identified using national U.S. Department of Veterans Affairs (VA) administrative data. Multivariable logistic regression analyses, adjusted for demographic characteristics and psychiatric comorbidities, were used to contrast the likelihood of receiving a medication class across genders. Sensitivity analyses using identical selection methods were conducted for the calendar years 2010, 2013, and 2016. In 2019, 877,785 veterans received treatment for PTSD within the VA, 13.5% of whom were women. Across medication classes and years, women were more likely to receive all psychiatric medications of interest. Relative to men, women were slightly more likely to receive antidepressants recommended for PTSD in 2019, adjusted odds ratio (aOR) = 1.07, 95% CI [1.06, 1.09]. However, gender differences for medications recommended against use for PTSD were notably larger, including benzodiazepines, aOR = 1.62, 95% CI [1.59, 1.65]; anticonvulsants. aOR = 1.41, 95% CI [1.38, 1.44]; and antidepressants recommended against use for PTSD, aOR = 1.26, 95% CI [1.19, 1.33]. To inform tailored intervention strategies, future work is needed to fully understand why women receive more medications recommended against use for PTSD.

Race Differences in Veteran's Affairs Emergency Department Utilization.

African Americans (AAs) experience disparities in chronic pain care. This study aimed to identify the rates of emergency department (ED) utilization for visits associated with chronic pain diagnoses among AAs compared to Whites and to determine variables that accounted for any differences. This retrospective observational study used national Veterans Affairs (Veteran's Health Administration) administrative data to identify Veterans with chronic pain diagnoses in 2018. Race/ethnicity was self-reported and assessed to examine if differences exist in ED utilization. Differences between AAs and Whites were examined using negative binomial regression models, controlling for ethnicity. Multivariable models (including demographics, pain characteristics, psychiatric comorbidities, medical comorbidities, pain-related health care utilization, and medication utilization) were examined to determine factors that contributed to these disparities. Among the 2,261,030 patients, 22% (n = 492,138) were AA. The incidence rate ratio of ED utilization for AAs, relative to Whites, was 1.58 (95% CI: 1.56-1.59). The only independent variable that produced a clinically meaningful reduction in the race effect on ED use was rurality, which was associated with reduced ED use. Post hoc model including all variables reduced the race effect to 1.37 (95% CI: 1.36-1.38). AA Veterans had a 58% greater risk of ED utilization for visits associated with chronic pain diagnoses relative to White Veterans, which remained meaningfully elevated after adjustment for observable confounders (37%). This observation may reflect disparities in outpatient chronic pain care for AAs. Future research could focus on enhancing therapeutic alliance in primary care to improve chronic pain treatment for AAs.

Opioid prescribing patterns for acute pain.

The current study aimed to identify patients presenting with acute pain who may be at risk for a complicated trajectory, via identifying clusters of early opioid prescribing patterns. National Veterans Affairs administrative data were utilized to build a cohort of outpatients with acute pain presentations and no more than minimal opioid use in the prior year. Latent Class Analyses (LCAs) identified clusters of early opioid prescribing patterns. The risk of progression to long-term opioid use was contrasted between LCA clusters using log-binomial regression, adjusting for confounding variables. The 2018 cohort included N=191,283. Among the 27,890 who received an initial opioid prescription, LCA classes were identified using: first supply day, total days dispensed across 30 days, opioid type, dose and number of prescriptions across the first 30 days. In the three-class model: class 1 indicated an immediate, low-dose and brief supply; class 2 included delayed, low-dose and longer duration prescriptions and class 3 included delayed, high-dose and moderate duration prescriptions. Adjusted relative risk ratios for progression to long-term opioid use in the following year were 3.33 (95% CI: 2.71-4.10) for class 1 (absolute risk 1.1%); 7.76 (95% CI: 6.69-8.99) for class 2 (3.1%) and 6.81 (95% CI: 5.72-8.12) for class 3 (2.4%) compared to patients who did not receive an acute opioid prescription (0.3%). These clusters of acute opioid prescribing could facilitate the identification of patients who may benefit from enhanced pain care earlier in the pain trajectory and decrease future reliance on long-term opioid therapy.

Organizational Readiness for Patient-Facing Mobile Teledermatology to Care for Established Veteran Patients in the United States.

Purpose: To improve patient access to skin care, the Department of Veterans Affairs (VA) developed a patient-facing asynchronous mobile teledermatology application (app), which allows patients to follow up remotely with dermatologists. To understand how the app would be received in VA, we examined Organizational Readiness for Change (ORC), an important prelude to effective implementation, which includes the shared resolve and collective ability of organizational members to implement a change. Methods: We used a mixed-methods multiple case study approach to assess ORC at three VA facilities. Data derived from a site process call, surveys, and semistructured telephone interviews of VA staff, field notes, and administrative data. Results: Participants at all three facilities supported the intervention and recognized the value of using the app to increase patients' access to dermatologists, but expressed concerns largely related to disruption of the pre-existing clinical workflow. Participants at the facility most actively using the app had the highest overall ORC score and reported the most facilitators. Facility leadership support when guided by a clinical champion minimized barriers by recognizing the complexities of health care provision at specialty clinics. Discussion: While provider buy-in remained a barrier, leadership, guided by the clinical champion, played a critical role instituting implementation strategies. The strong association between the ORC survey score and the presence of facilitators and barriers suggests that the ORC survey may be a rapid, convenient, and effective tool for health care systems to identify favorable sites for wider implementation of mobile telehealth care.
