Racial and ethnic disparities in the VA health care system: a systematic review

Understanding Racial Disparities in Dementia Prevalence Among Veterans

Background

Black and Hispanic older adults have greater incidence of Alzheimer's disease and related dementias relative to White adults, but factors underlying these disparities are not well understood, limiting the ability to address them.

Objective

To determine the impact of demographics, cardiovascular disease (CVD) and risk factors, social determinants of health (SDOH), and neuropsychiatric risk factors on racial/ethnic disparities in dementia risk among Veterans.

Methods

We examined a random sample of 1,579,919 older Veterans (age ≥55) without dementia who received care from the VHA from October 1, 1999 to September 30, 2021. All variables were extracted from national VHA data. We used Cox proportional hazard regression models to examine change in variance in risk of dementia across racial/ethnic groups.

Results

During follow up (mean 11.1 years), 13% of Veterans developed dementia. Relative to White Veterans, the adjusted hazard ratios (AHRs) for developing dementia in sex-adjusted models with age as timescale were 1.65 (95% CI, 1.63-1.67) for Black Veterans and 1.50 (95% CI, 1.44-1.56) for Hispanic Veterans. In the model examining CVD and risk factors, AHRs were 1.53 (95% CI, 1.50-1.55) for Black Veterans and 1.38 (95% CI, 1.33-1.44) for Hispanic Veterans. In the model examining SDOH, AHRs were 1.46 (95% CI, 1.43-1.49) for Black Veterans and 1.34 (95% CI, 1.29-1.40) for Hispanic Veterans.

Conclusions

SDOH and CVD and risk factors accounted for the greatest amount of variance in racial/ethnic disparities in dementia risk. Cardiovascular disease and SDOH are strong possible targets for interventions designed to reduce these disparities.

Treatment Goals and Preferences of Black Veterans with Chronic Musculoskeletal Pain

Understanding patient goals and preferences is critical in the context of complex conditions such as chronic pain. This need may be especially pronounced for Black patients, who experience significant health and healthcare disparities. The primary aim of this study was to describe the treatment goals and preferences of Black veterans with chronic musculoskeletal pain who were enrolled in the intervention arm of a randomized controlled trial testing a coaching intervention. In the coaching sessions, participants (n = 106) identified their most important pain-related treatment goals and preferences. Participants' top treatment goals were to improve physical functioning (61%), increase engagement in valued activities (45%), and reduce pain intensity (37%). Most participants (73%) preferred non-pharmacological treatments (eg, physical therapy, exercise, acupuncture, yoga). The 17% of participants who identified medications as a preferred treatment demonstrated higher levels of depression and anxiety compared to those who did not. Approximately 42% and 21% of participants stated a preference to avoid pharmacological and surgical pain treatments, respectively. Black patients with chronic pain prioritize improving physical functioning and pain intensity in service of increasing their engagement in exercise, work, relationships, and leisure activities. Also, in the current study, patients expressed a clear preference for non-pharmacological pain treatments. Future research should investigate ways to improve communication of goals and preferences with providers and facilitate access to non-pharmacological treatments for Black patients with chronic pain. PERSPECTIVE: This article describes the treatment goals and preferences of Black veterans with chronic pain. Most patients prioritized goals to improve physical functioning, pain severity, and participation in valued activities. Patients primarily preferred non-pharmacological treatments. This emphasizes the need for clear communication with Black patients regarding pain-related goals and non-pharmacological treatment options.

Health Conditions and Treatment Utilization Among Older Male Veterans Incarcerated in Prisons

BACKGROUND

More than 50,000 older male veterans incarcerated in prisons are expected to return to their communities and utilize the Veterans Health Administration (VHA) and community healthcare systems. To support the continuity of healthcare and overall successful community reentry of older incarcerated veterans, an understanding of their health profiles and treatment utilization while in correctional care is needed.

OBJECTIVE

To assess the health status of older male veterans incarcerated in state prisons and explore demographic, military, and VHA-related factors associated with medical conditions, disabilities, behavioral conditions, and medical and behavioral treatment utilization.

DESIGN/PARTICIPANTS

Cross-sectional observational study of 880 male veterans aged 50 + incarcerated in state prisons using data from the 2016 Bureau of Justice Statistics Survey of Prison Inmates.

MAIN MEASURES

Veteran status, self-report health status, and treatment utilization since prison admission. Prevalence rates for conditions and treatment utilization were calculated. Logistic regression models were used to examine the association of characteristics with conditions and treatment utilization.

KEY RESULTS

Among the 880 older male veterans in state prisons, the majority reported having a current medical condition (79.3%) or disability (61.6%), almost half had history of a mental health condition (44.5%), and more than a quarter (29%) had a substance use disorder. Compared to White veterans, Black veterans were less likely to report a disability or mental health condition. Few demographic, military, and VA-related characteristics were associated with medical or behavioral conditions or treatment utilization.

CONCLUSION

Our results suggest that the VHA and community healthcare systems need to be prepared to address medical and disability conditions among the majority of older male veterans who will be leaving prison and returning to their communities. Integrated medical and behavioral healthcare delivery models may be especially important for these veterans as many did not receive behavioral health treatment while in prison.

Racial and Ethnic Differences in Health Care Experiences for Veterans Receiving VA Community Care from 2016 to 2021

BACKGROUND

Prior research documented racial and ethnic disparities in health care experiences within the Veterans Health Administration (VA). Little is known about such differences in VA-funded community care programs, through which a growing number of Veterans receive health care. Community care is available to Veterans when care is not available through the VA, nearby, or in a timely manner.

OBJECTIVE

To examine differences in Veterans' experiences with VA-funded community care by race and ethnicity and assess changes in these experiences from 2016 to 2021.

DESIGN

Observational analyses of Veterans' ratings of community care experiences by self-reported race and ethnicity. We used linear and logistic regressions to estimate racial and ethnic differences in community care experiences, sequentially adjusting for demographic, health, insurance, and socioeconomic factors.

PARTICIPANTS

Respondents to the 2016-2021 VA Survey of Healthcare Experiences of Patients-Community Care Survey.

MEASURES

Care ratings in nine domains.

KEY RESULTS

The sample of 231,869 respondents included 24,306 Black Veterans (mean [SD] age 56.5 [12.9] years, 77.5% male) and 16,490 Hispanic Veterans (mean [SD] age 54.6 [15.9] years, 85.3% male). In adjusted analyses pooled across study years, Black and Hispanic Veterans reported significantly lower ratings than their White and non-Hispanic counterparts in five of nine domains (overall rating of community providers, scheduling a recent appointment, provider communication, non-appointment access, and billing), with adjusted differences ranging from - 0.04 to - 0.13 standard deviations (SDs) of domain scores. Black and Hispanic Veterans reported higher ratings with eligibility determination and scheduling initial appointments than their White and non-Hispanic counterparts, and Black Veterans reported higher ratings of care coordination, with adjusted differences of 0.05 to 0.21 SDs. Care ratings improved from 2016 to 2021, but differences between racial and ethnic groups persisted.

CONCLUSIONS

This study identified small but persistent racial and ethnic differences in Veterans' experiences with VA-funded community care, with Black and Hispanic Veterans reporting lower ratings in five domains and, respectively, higher ratings in three and two domains. Interventions to improve Black and Hispanic Veterans' patient experience could advance equity in VA community care.

Factors Associated with Delayed Care Among Women Veterans Actively Engaged in Primary Care

Background: Delaying needed medical care contributes to greater health risks and higher long-term medical costs. Women Veterans with complex medical and mental health needs face increased barriers to timely care access. Objectives: In a sample of women Veterans with recent engagement in Veterans Administration (VA) primary care, we aimed to compare characteristics of women Veterans who delayed care in the past 6 months with those who did not and examine factors associated with self-reported delayed care. Our study aims to inform interventions focused on eliminating health care access disparities among women Veterans. Materials and Methods: An innovation to improve women Veterans' engagement and retention in evidence-based health care for cardiovascular (CV) risk reduction (CV Toolkit) was implemented across five primary care sites within the VA. Women Veterans who were exposed to at least one CV Toolkit component participated in a mailed survey (n = 253). We used multivariate logistic regression to model factors associated with delaying care, including trust in VA providers, positive mental health screening (i.e., positive screen for either depression or anxiety), traumatic experience, self-rated health, and age. Results: Women with any mental health symptoms (odds ratio [OR] 2.42, 95% confidence interval [CI]: 1.23-4.74) and women who had experienced a traumatic event (OR 2.61, 95%CI: 1.11-6.14) were significantly more likely to report delaying care. Conclusions: Our study identified high rates of delayed care-over one-third of respondents-among women Veterans with recent primary care engagement. Mental health symptoms were the most common reported reason for delay among those who delayed care. Clinical Trial registration: NCT02991534.

Mental health treatment utilization among Gulf War era veterans with probable alcohol use disorder

INTRODUCTION

Alcohol use disorder (AUD) is prevalent among veterans, and excessive alcohol use is associated with significant mental and physical health consequences. Currently, the largest cohort of veterans seeking services at the VA are those from the 1990s Gulf War Era. This cohort of veterans is unique due to the nature of their deployment resulting in a myriad of unexplained symptoms collectively known as "Gulf War Illness" and higher rates of mental health problems. The present study sought to examine the association between probable AUD and mental health treatment utilization in a sample of 1126 (882 male) Gulf War-era veterans.

METHODS

Veterans completed a self-report survey including the AUDIT-C, questions about mental health treatment engagement, and demographic questions.

RESULTS

Results demonstrated that approximately 20 % of the sample screened positive for probable AUD, determined by standard AUDIT-C cutoff scores. Among those screening positive for AUD, 25 % reported engaging in mental health treatment in the past year. Veterans with probable AUD who use VA care had 3.8 times the odds of receiving mental health services than veterans not using VA care. Use of mental health services was associated with mental health comorbidity and identifying as Black/African American.

CONCLUSIONS

The results of the present study highlight a significant unmet need for mental health treatment among Gulf War-era veterans with AUD.

Blood Pressure Control and Maintenance in a Prospective Cohort of Younger Veterans: Roles of Sex, Race, Ethnicity, and Social Determinants of Health

Background

Proactive blood pressure (BP) management is particularly beneficial for younger Veterans, who have a greater prevalence and earlier onset of cardiovascular disease than non-Veterans. It is unknown what proportion of younger Veterans achieve and maintain BP control after hypertension onset and if BP control differs by demographics and social deprivation.

Methods

Electronic health records were merged from Veterans who enrolled in VA care 10/1/2001-9/30/2017 and met criteria for hypertension - first diagnosis or antihypertensive fill. BP control (140/90 mmHg), was estimated 1, 2, and 5 years post-hypertension documentation, and characterized by sex, race, and ethnicity. Adjusted logistic regressions assessed likelihood of BP control by these demographics and with the Social Deprivation Index (SDI).

Results

Overall, 17% patients met criteria for hypertension (n=198,367; 11% of women, median age 41). One year later, 59% of men and 65% of women achieved BP control. After adjustment, women had a 72% greater odds of BP control than men, with minimal change over 5 years. Black adults had a 22% lower odds of BP control than White adults. SDI did not significantly change these results.

Conclusions

In the largest study of hypertension in younger Veterans, 41% of men and 35% of women did not have BP control after 1 year, and BP control was consistently better for women through 5 years. Thus, the first year of hypertension management portends future, long-term BP control. As social deprivation did not affect BP control, the VA system may protect against disadvantages observed in the general U.S. population.

Racial/Ethnic and Geographic Disparities in Comorbid Traumatic Brain Injury-Renal Failure in US Veterans and Associated Veterans Affairs Resource Costs, 2000-2020

Studies have identified disparities by race/ethnicity and geographic status among veterans with traumatic brain injury (TBI) and renal failure (RF). We examined the association of race/ethnicity and geographic status with RF onset in veterans with and without TBI, and the impact of disparities on Veterans Health Administration resource costs.

METHODS

Demographics by TBI and RF status were assessed. We estimated Cox proportional hazards models for progression to RF and generalized estimating equations for inpatient, outpatient, and pharmacy cost annually and time since TBI + RF diagnosis, stratified by age.

RESULTS

Among 596,189 veterans, veterans with TBI progressed faster to RF than those without TBI (HR 1.96). Non-Hispanic Black veterans (HR 1.41) and those in US territories (HR 1.71) progressed faster to RF relative to non-Hispanic Whites and those in urban mainland areas. Non-Hispanic Blacks (-$5,180), Hispanic/Latinos ($-4,984), and veterans in US territories (-$3,740) received fewer annual total VA resources. This was true for all Hispanic/Latinos, while only significant for non-Hispanic Black and US territory veterans < 65 years. For veterans with TBI + RF, higher total resource costs only occurred ≥ 10 years after TBI + RF diagnosis ($32,361), independent of age. Hispanic/Latino veterans ≥ 65 years received $8,248 less than non-Hispanic Whites and veterans living in US territories < 65 years received $37,514 less relative to urban veterans.

CONCLUSION

Concerted efforts to address RF progression in veterans with TBI, especially in non-Hispanic Blacks and those in US territories, are needed. Importantly, culturally appropriate interventions to improve access to care for these groups should be a priority of the Department of Veterans Affairs priority for these groups.

Race-Based Disparities in the Frequency and Duration of Restraint Use in a Psychiatric Inpatient Setting

OBJECTIVE

Patients' race and age have each been identified as risk factors for experiencing restraint events during psychiatric hospitalization. Restraint duration is also an important variable in determining disparities in treatment. To the authors' knowledge, no studies to date have examined the effect of the interaction of race and age on restraint use and duration in inpatient psychiatric settings. This retrospective chart review of electronic medical records of patients admitted between 2012 and 2019 sought to examine whether race and age interacted in predicting differences in the use and duration of restraints in a psychiatric inpatient setting.

METHODS

Logistic and hierarchical regression analyses were conducted on data from a sample of 29,739 adolescent (ages 12-17 years) and adult (ages ≥18 years) inpatients to determine whether the interaction of race and age group (adolescent or adult) significantly predicted a restraint event or differences in restraint duration.

RESULTS

Black (adjusted OR [AOR]=1.85) and multiracial (AOR=1.36) patients were more likely to experience a restraint event than were their White peers. Black race was also significantly (p=0.001) associated with longer restraint duration. No significant interaction was detected between race and age in predicting restraint events or duration.

CONCLUSIONS

Although the interaction between race and age did not predict restraint events or duration, the findings indicate racial disparities in the frequency and duration of restraint events among Black and multiracial individuals and may inform efforts to reduce these events.

Examining cancer screening disparities by race/ethnicity and insurance groups: A comparison of 2008 and 2018 National Health Interview Survey (NHIS) data in the United States

BACKGROUND

Pervasive differences in cancer screening among race/ethnicity and insurance groups presents a challenge to achieving equitable healthcare access and health outcomes. However, the change in the magnitude of cancer screening disparities over time has not been thoroughly examined using recent public health survey data.

METHODS

A retrospective cross-sectional analysis of the 2008 and 2018 National Health Interview Survey (NHIS) database focused on breast, cervical, and colorectal cancer screening rates among race/ethnicity and insurance groups. Multivariable logistic regression models were used to assess the relationship between cancer screening rates, race/ethnicity, and insurance coverage, and to quantify the changes in disparities in 2008 and 2018, adjusting for potential confounders.

RESULTS

Colorectal cancer screening rates increased for all groups, but cervical and mammogram rates remained stagnant for specific groups. Non-Hispanic Asians continued to report consistently lower odds of receiving cervical tests (OR: 0.42, 95% CI: 0.32-0.55, p<0.001) and colorectal cancer screening (OR: 0.55, 95% CI: 0.42-0.72, p<0.001) compared to non-Hispanic Whites in 2018, despite significant improvements since 2008. Non-Hispanic Blacks continued to report higher odds of recent cervical cancer screening (OR: 1.98, 95% CI: 1.47-2.68, p<0.001) and mammograms (OR: 1.32, 95% CI: 1.02-1.71, p<0.05) than non-Hispanic Whites in 2018, consistent with higher odds observed in 2008. Hispanic individuals reported improved colorectal cancer screening over time, with no significant difference compared to non-Hispanics Whites in 2018, despite reporting lower odds in 2008. The uninsured status was associated with significantly lower odds of cancer screening than private insurance for all three cancers in 2008 and 2018.

CONCLUSION

Despite an overall increase in breast and colorectal cancer screening rates between 2008 and 2018, persistent racial/ethnic and insurance disparities exist among race/ethnicity and insurance groups. These findings highlight the importance of addressing underlying factors contributing to disparities among underserved populations and developing corresponding interventions.

Sexual Orientation and Racial Bias in Relation to Medical Specialty

Physician explicit and implicit biases involving race and sexual orientation (SO) affect patient and provider experiences in healthcare settings. An anonymous survey was disseminated nationally to graduating medical students, residents, and practicing physicians to evaluate SO and racial biases across medical specialties. SO explicit and implicit bias were measured with the Attitudes toward Lesbians and Gay Men Scale, short form (ATLG-S) and Gay-Straight Implicit Association Test (IAT). Racial explicit and implicit bias were measured with the Quick Discrimination Index (QDI) and the Black-White IAT. Medical specialty was associated with racial explicit bias and specialty prestige with Black-White IAT score. Medical specialty and specialty prestige were not associated with SO bias. Female sex, sexual and gender minority (SGM) identity, and decreased religiosity were associated with reduced SO and racial bias. Provider race was associated with racial implicit and explicit bias.

Community Level Correlates of COVID-19 Booster Vaccine Hesitancy in the United States: A Cross-Sectional Analysis

Introduction: Evidence exists that individual-level sociodemographic factors contribute to vaccine hesitancy, but it is unknown how community-level factors affect COVID-19 booster dose hesitancy. The current study aims to fill this knowledge gap by comparing data from a nationwide survey on COVID-19 vaccine hesitancy with a community-level indicator, i.e., the Distressed Communities Index (DCI). Methods: Attitudes toward vaccinations, vaccine literacy, COVID-19 vaccine confidence index, and trust were measured using a 48-item, psychometrically valid and reliable survey tool. In this study, 2138 survey participants residing in the United States were divided into quintiles of varying community distress levels based on their zip codes using the DCI. Data were analyzed through Chi-square, one-way ANOVA, and post hoc analysis with Tukey's test. Results: A significantly higher proportion of participants from the distressed communities had lower trust than their prosperous counterparts (26.6% vs. 37.6%, p < 0.001). On the contrary, participants from the prosperous communities had significantly higher vaccine confidence index scores than those in distressed communities (2.22 ± 1.13 vs. 1.70 ± 1.01, p < 0.001). Conclusions: These findings affirm the importance of developing community-level interventions to promote trust in COVID-19 vaccinations and increase booster dose uptake. From these results, future studies can examine the efficacy of various community-level interventions.

Communication and Activation in Pain to Enhance Relationships and Treat Pain with Equity (COOPERATE): a Qualitative Analysis of a Tailored Coaching Program for Black Patients with Chronic Pain

BACKGROUND

Racial inequities in pain treatment are well-documented and persist despite national priorities focused on health equity. The COOPERATE (Communication and Activation in Pain to Enhance Relationships and Treat Pain with Equity) intervention was a patient-centered, tailored intervention aimed at improving health equity by targeting patient activation-the knowledge and confidence to manage one's health. COOPERATE led to significant and sustained increases in patient activation, significant short-term increases in communication self-efficacy (confidence to communicate with clinicians), and more intervention participants experienced clinically significant (≥ 30%) reductions in pain at 3 months than control group participants.

OBJECTIVE

To understand how participants experienced the intervention, including their perspectives on its effects on their health and healthcare experiences.

DESIGN

Semi-structured qualitative interviews.

PARTICIPANTS

Black veterans with chronic pain who participated in the COOPERATE intervention.

KEY RESULTS

Participants described acquiring new tools and cultivating skills to use in their clinic visits, including preparing for their visit (writing an agenda, listing questions); asking focused, effective questions; and expressing concerns and communicating goals, values, and preferences. Participants indicated that by putting these tools to use, they felt more confident and able to take ownership of their own pain care; for some, this led to better pain management and improved pain. Participants expressed mixed views of disparities in pain care, with some believing race and racism did not play a role in their care, while others valued being part of an intervention that helped equip them with tools to exercise autonomy over their healthcare.

CONCLUSIONS

Black patients with chronic pain described gaining greater confidence to self-manage and communicate with their clinicians after participating in the COOPERATE intervention. With its focus on empowering individuals, the COOPERATE intervention represents a promising approach to help advance equity in pain care.

Communication and activation in pain to enhance relationships and treat pain with equity (COOPERATE): a randomized clinical trial

ABSTRACT

Racialized disparities in chronic pain care are well-documented and persist despite national priorities focused on health equity. Similar disparities have been observed in patient activation (ie, having the knowledge, confidence, and skills to manage one's health). As such, interventions targeting patient activation represent a novel approach to addressing and reducing disparities in pain care. Communication and Activation in Pain to Enhance Relationships and Treat Pain with Equity is a randomized controlled trial of a 6-session telephone-delivered intervention to increase patient activation for Black patients with chronic pain. Two hundred fifty Black patients from a Midwestern Veterans Affairs medical center were randomized to the intervention or attention control. The primary outcome was patient activation; secondary outcomes included communication self-efficacy, pain, and psychological functioning. Outcomes were assessed at baseline and at 3 (primary endpoint), 6, and 9 months (sustained effects). Analyses used an intent-to-treat approach. Compared with baseline, patient activation increased 4.6 points at 3 months (versus +0.13 in control group, 95% CI: 0.48, 7.34; P = 0.03). These improvements in the intervention group were sustained, with +7 from baseline at 6 months and +5.77 at 9 months, and remained statistically significant from the control group. Communication self-efficacy increased significantly relative to the control group from baseline to 3 months. Pain intensity and interference improved at 3 months, but differences were not significant after adjusting for multiple comparisons. Most other secondary outcomes improved, but group differences were not statistically significant after controlling for multiple comparisons. Results suggest that increasing patient activation is a potentially fruitful path toward improving pain management and achieving health equity.

Assessment of Dementia in Minority Ethnic Groups in Scotland: Results of a Survey of Cognitive Specialists

OBJECTIVE

Minority ethnic groups (MEGs) in Europe receive suboptimal dementia evaluation, yet related research in Scotland is lacking. This research examined the evaluation of dementia in MEGs in Scotland and compared it with previous research to highlight the changes in the clinical evaluation of dementia over the decade.

DESIGN AND SETTING

A self-administered survey was created online and emailed to 14 Heads of the boards under the Scottish National Health Service and dementia-associated settings and organizations.

RESULTS

Most surveyed centers (85.6%) received MEG referrals. Although 92.9% of the centers used professional translators when needed, 85.7% thought assessing dementia in MEGs was difficult, mostly due to the suitability of test instruments and rating scales and patients' linguistic abilities. Very few found their skills to be good in evaluating MEGs. There was no mention of specialized dementia services for MEGs.

CONCLUSIONS

The lack of culturally appropriate instruments and specialized dementia services reveals that the services are not ready to meet the demand for evaluating patients from diverse cultural and language backgrounds. Inadequate clinical evaluation may lead to misdiagnoses. Therefore, although significant work has been carried out in the past few years, improvements must be continued to enhance the current practices and apply suitable evaluation methods for MEGs.

Identifying predictors of the amount of veteran participation in cognitive behavioral therapy for insomnia in the Veterans Affairs health care system

Insomnia is a prevalent and negatively impactful disorder among veterans. The Department of Veterans Affairs (VA) has committed significant resources to the development and dissemination of training related to cognitive behavioral therapy for insomnia (CBT-I), the recommended first-line intervention for chronic insomnia disorder. It has been established that VA clinicians can be effectively trained to deliver high fidelity CBT-I and that treatment results in significant improvements in insomnia. However, there is a paucity of research examining rates and predictors of veterans' participation in CBT-I in routine VA clinical care. In this study, we conducted a secondary analysis of data from VA electronic health records (EHR) to determine individual predisposing, enabling, and need factors associated with CBT-I participation. The sample included veterans who had at least one CBT-I templated note from the VA mid-Atlantic region of the United States (VISN4) between 2015 and 2019 in their chart (N = 2,801). CBT-I participation was defined by number of CBT-I templated notes occurring within a 6-month period from the initial note. Findings indicated that veterans most often completed only one session of CBT-I and, on average, completed approximately three sessions. Results from multinomial logistic regression identified significant associations of race, the presence of comorbid mental health disorders, rurality, presence of insomnia diagnosis, and insomnia medication with CBT-I participation; associations varied depending on how CBT-I participation was defined. More work is needed to better understand factors contributing to participation and reasons for completion and noncompletion of CBT-I. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Factors Associated with Military Sexual Trauma (MST) Disclosure During VA Screening Among Women Veterans

BACKGROUND

Capturing military sexual trauma (MST) exposure is critical for Veterans' health equity. For many, it improves access to VA services and allows for appropriate care.

OBJECTIVE

Identify factors associated with nondisclosure of MST in VA screening among women.

DESIGN

Cross-sectional telephone survey linked with VA electronic health record (EHR) data.

PARTICIPANTS

Women Veterans using primary care or women's health services at 12 VA facilities in nine states.

MAIN MEASURES

Survey self-reported MST (sexual assault and/or harassment during military service), socio-demographics and experiences with VA care, as well as EHR MST results. Responses were categorized as "no MST" (no survey or EHR MST), "MST captured by EHR and survey," and "MST not captured by EHR" (survey MST but no EHR MST). We used stepped multivariable logistic regression to examine "MST not captured by EHR" as a function of socio-demographics, patient experiences, and screening method (survey vs. EHR).

KEY RESULTS

Among 1287 women (mean age 50, SD 15), 35% were positive for MST by EHR and 61% were positive by survey. Approximately 38% had "no MST," 34% "MST captured by EHR and survey," and 26% "MST not captured by EHR". In fully adjusted models, odds of "MST not captured by EHR" were higher among Black and Latina women compared to white women (Black: OR = 1.6, 1.2-2.2; Latina: OR = 1.9, 1.0-3.6). Women who endorsed only sexual harassment in the survey (vs. sexual harassment and sexual assault) had fivefold higher odds of "MST not captured by EHR" (OR = 4.9, 3.2-7.3). Women who were screened for MST in the EHR more than once had lower odds of not being captured (OR = 0.3, 0.2-0.4).

CONCLUSIONS

VA screening for MST may disproportionately under capture patients from historically minoritized ethnic/racial groups, creating inequitable access to resources. Efforts to mitigate screening disparities could include re-screening and reinforcing that MST includes sexual harassment.

Factors That Impact the Long-Term Outcome of Postconcussive Dizziness Among Post-9/11 Veterans

PURPOSE

The primary aim of this study was to examine the factors associated with long-term outcomes of postconcussive disruptive dizziness in Veterans of the post-9/11 wars.

METHOD

For this observational cohort study, the Neurobehavioral Symptom Inventory-Vestibular subscale (NSI-V) score was used as an outcome measure for dizziness in 987 post-9/11 Veterans who indicated disruptive dizziness at an initial Veterans Health Administration Comprehensive Traumatic Brain Injury Evaluation (CTBIE). An NSI-V change score was calculated as the difference in the scores obtained at the initial CTBIE and on a subsequent survey. Differences in the NSI-V change scores were examined for demographics, injury characteristics, comorbidities, and vestibular and balance function variables, and multiple linear regression analyses were used to explore associations among the variables and the NSI-V change score.

RESULTS

The majority of Veterans (61%) demonstrated a decrease in the NSI-V score, suggesting less dizziness on the survey compared with the CTBIE; 16% showed no change; and 22% had a higher score. Significant differences in the NSI-V change score were observed for traumatic brain injury (TBI) status, diagnoses of post-traumatic stress disorder (PTSD), headache and insomnia, and vestibular function. Multivariate regressions revealed significant associations between the NSI-V change score and the initial CTBIE NSI-V score, education level, race/ethnicity, TBI status, diagnoses of PTSD or hearing loss, and vestibular function.

CONCLUSIONS

Postconcussive dizziness can continue for years following an injury. Factors associated with poor prognosis include TBI, diagnoses of PTSD or hearing loss, abnormal vestibular function, increased age, identification as a Black Veteran, and high school education level.

Rural and Urban Hispanic Patients of the Veterans Health Administration

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.

An Examination of Racial/Ethnic Differences on the Neurobehavioral Symptom Inventory Among Veterans Completing the Comprehensive Traumatic Brain Injury Evaluation: A Veterans Affairs Million Veteran Program Study

OBJECTIVE

The purpose of this study was to explore racial/ethnic differences in neurobehavioral symptom reporting and symptom validity testing among military veterans with a history of traumatic brain injury (TBI).

METHOD

Participants of this observational cross-sectional study (N = 9,646) were post-deployed Iraq-/Afghanistan-era veterans enrolled in the VA's Million Veteran Program with a clinician-confirmed history of TBI on the Comprehensive TBI Evaluation (CTBIE). Racial/ethnic groups included White, Black, Hispanic, Asian, Multiracial, Another Race, American Indian or Alaska Native, and Native Hawaiian or Other Pacific Islander. Dependent variables included neurobehavioral symptom domains and symptom validity assessed via the Neurobehavioral Symptom Inventory (NSI) and Validity-10, respectively.

RESULTS

Chi-square analyses showed significant racial/ethnic group differences for vestibular, somatic/sensory, and affective symptoms as well as for all Validity-10 cutoff scores examined (≥33, ≥27, ≥26, >22, ≥22, ≥13, and ≥7). Follow-up analyses compared all racial/ethnic groups to one another, adjusting for sociodemographic- and injury-related characteristics. These analyses revealed that the affective symptom domain and the Validity-10 cutoff of ≥13 revealed the greatest number of racial/ethnic differences.

CONCLUSIONS

Results showed significant racial/ethnic group differences on neurobehavioral symptom domains and symptom validity testing among veterans who completed the CTBIE. An enhanced understanding of how symptoms vary by race/ethnicity is vital so that clinical care can be appropriately tailored to the unique needs of all veterans. Results highlight the importance of establishing measurement invariance of the NSI across race/ethnicity and underscore the need for ongoing research to determine the most appropriate Validity-10 cutoff score(s) to use across racially/ethnically diverse veterans.

Comorbidity and polypharmacy impact neurobehavioral symptoms and symptom validity failure among post-9/11 veterans with mild traumatic brain injury

Objective

The study aimed to examine the association between post-concussive comorbidity burdens [post-traumatic stress disorder (PTSD), depression, and/or headache] and central nervous system (CNS) polypharmacy (five or more concurrent medications) with reported neurobehavioral symptoms and symptom validity screening among post-9/11 veterans with a history of mild traumatic brain injury (mTBI).

Setting

Administrative medical record data from the Department of Veterans Affairs (VA) were used in the study.

Participants

Post-9/11 veterans with mTBI and at least 2 years of VA care between 2001 and 2019 who had completed the comprehensive traumatic brain injury evaluation (CTBIE) were included in the study.

Design

Retrospective cross-sectional design was used in the study.

Main measures

Neurobehavioral Symptom Inventory (NSI), International Classification of Diseases, Ninth Revision, and Clinical Modification diagnosis codes were included in the study.

Results

Of the 92,495 veterans with a history of TBI, 90% had diagnoses of at least one identified comorbidity (PTSD, depression, and/or headache) and 28% had evidence of CNS polypharmacy. Neurobehavioral symptom reporting and symptom validity failure was associated with comorbidity burden and polypharmacy after adjusting for sociodemographic characteristics. Veterans with concurrent diagnoses of PTSD, depression, and headache were more than six times more likely [Adjusted odds ratio = 6.55 (99% CI: 5.41, 7.92)]. to fail the embedded symptom validity measure (Validity-10) in the NSI.

Conclusion

TBI-related multimorbidity and CNS polypharmacy had the strongest association with neurobehavioral symptom distress, even after accounting for injury and sociodemographic characteristics. Given the regular use of the NSI in clinical and research settings, these findings emphasize the need for comprehensive neuropsychological evaluation for individuals who screen positively for potential symptom overreporting, the importance of multidisciplinary rehabilitation to restore functioning following mTBI, and the conscientious utilization of symptom validity measures in research efforts.

Racial Disparities in Lung Cancer Screening Among Veterans, 2013 to 2021

Importance

Racial disparities in lung cancer screening (LCS) are often ascribed to barriers such as cost, insurance status, access to care, and transportation. Because these barriers are minimized within the Veterans Affairs system, there is a question of whether similar racial disparities exist within a Veterans Affairs health care system in North Carolina.

Objectives

To examine whether racial disparities in completing LCS after referral exist at the Durham Veterans Affairs Health Care System (DVAHCS) and, if so, what factors are associated with screening completion.

Design, Setting, and Participants

This cross-sectional study assessed veterans referred to LCS between July 1, 2013, and August 31, 2021, at the DVAHCS. All included veterans self-identified as White or Black and met the US Preventive Services Task Force eligibility criteria as of January 1, 2021. Participants who died within 15 months of consultation or who were screened before consultation were excluded.

Exposures

Self-reported race.

Main Outcomes and Measures

Screening completion was defined as completing computed tomography for LCS. The associations among screening completion, race, and demographic and socioeconomic risk factors were assessed using logistic regression models.

Results

A total of 4562 veterans (mean [SD] age, 65.4 [5.7] years; 4296 [94.2%] male; 1766 [38.7%] Black and 2796 [61.3%] White) were referred for LCS. Of all veterans referred, 1692 (37.1%) ultimately completed screening; 2707 (59.3%) never connected with the LCS program after referral and an informational mailer or telephone call, indicating a critical point in the LCS process. Screening rates were substantially lower among Black compared with White veterans (538 [30.5%] vs 1154 [41.3%]), with Black veterans having 0.66 times lower odds (95% CI, 0.54-0.80) of screening completion after adjusting for demographic and socioeconomic factors.

Conclusions and Relevance

This cross-sectional study found that after referral for initial LCS via a centralized program, Black veterans had 34% lower odds of LCS screening completion compared with White veterans, a disparity that persisted even after accounting for numerous demographic and socioeconomic factors. A critical point in the screening process was when veterans must connect with the screening program after referral. These findings may be used to design, implement, and evaluate interventions to improve LCS rates among Black veterans.

Understanding the Context for Incorporating Equity into Quality Improvement Throughout a National Health Care System

Purpose

Although health care systems aspire to deliver equitable care, practical tools that empower the health care workforce to weave equity throughout quality improvement (QI) processes are lacking. In this article, we report findings from context of use interviews that informed the development of a user-centered tool to support equity-focused QI.

Methods

Semistructured interviews were conducted from February to April of 2019. Participants included 14 medical center administrators, departmental or service line leaders, and clinical staff involved in direct patient care from three Veterans Affairs (VA) Medical Centers within a single region. Interviews covered existing practices for monitoring health care quality (i.e., priorities, tasks, workflow, and resources) and explored how equity data might fit into current processes. Themes extracted through rapid qualitative analysis were used to draft initial functional requirements for a tool to support equity-focused QI.

Results

Although the potential value of examining disparities in health care quality was clearly recognized, the data necessary for examining disparities were lacking for most quality measures. Interviewees also desired guidance on how inequities could be addressed through QI. The ways in which QI initiatives were selected, carried out, and supported also had important design implications for tools to support equity-focused QI.

Discussion

The themes identified in this work guided the development of a national VA Primary Care Equity Dashboard to support equity-focused QI within VA. Understanding the ways in which QI was carried out across multiple levels of the organization provided a successful foundation upon which to build functional tools to support thoughtful engagement around equity in clinical settings.

Arteriovenous Graft Failure in the Veterans Health Administration: Outcome Disparities Associated with Race

Background Vascular access for ongoing hemodialysis often fails, frequently requiring repeated procedures to maintain vascular patency. While research has shown racial discrepancies in multiple aspects of renal failure treatment, there is poor understanding of how these factors might relate to vascular access maintenance procedures after arteriovenous graft (AVG) placement. Purpose To evaluate racial disparities associated with premature vascular access failure after percutaneous access maintenance procedures following AVG placement using a retrospective national cohort from the Veterans Health Administration (VHA). Materials and Methods All hemodialysis vascular maintenance procedures performed at VHA hospitals between October 2016 and March 2020 were identified. To ensure the sample represented patients who consistently used the VHA, patients without AVG placement within 5 years of their first maintenance procedure were excluded. Access failure was defined as a repeat access maintenance procedure or as hemodialysis catheter placement occurring 1-30 days after the index procedure. Multivariable logistic regression analyses were performed to calculate prevalence ratios (PRs) measuring the association between hemodialysis maintenance failure and African American race compared with all other races. Models controlled for vascular access history, patient socioeconomic status, and procedure and facility characteristics. Results In total, 1950 access maintenance procedures in 995 patients (mean age, 69 years ± 9 [SD], 1870 men) with an AVG created in one of 61 VHA facilities were identified. Most procedures involved African American patients (1169 of 1950, 60%) and patients residing in the South (1002 of 1950, 51%). Premature access failure occurred in 215 of 1950 (11%) procedures. When compared with all other races, African American race was associated with premature access site failure (PR, 1.4; 95% CI: 1.07, 1.43; P = .02). Among the 1057 procedures in 30 facilities with interventional radiology resident training programs, there was no evidence of racial disparity in the outcome (PR, 1.1; P = .63). Conclusion African American race was associated with higher risk-adjusted rates of premature arteriovenous graft failure after dialysis maintenance. © RSNA, 2023 Supplemental material is available for this article.

The Effects of Osteoarthritis on Depressive Symptomatology Among Older U.S. Military Veterans

Osteoarthritis (OA) is a leading cause of disability among older adults. By 2050, approximately 60 million will suffer from arthritis adding up to a total societal cost of $65 billion. Chronic illnesses resulting in pain, and functional decline have been associated with depression in previous studies.A causal model was developed and tested using structural equation modeling that examined depression scores of 503 older (age 50-85), male Veterans with moderate to severe symptomatic OA of the knee\hip.The results of the structural equation modeling produced a final model of depressive symptomatology that fit the data well (Chi square = 12.23, DF = 11, p = .346; TLI = .99; CFI = 1.00; RMSEA = .02).The findings indicate the central role that OA severity (pain, stiffness, and functional difficulties) plays in the mental health of older Veterans in terms of the level of reported depressive symptoms.

Healthcare Access and Delivery During the COVID-19 Pandemic for Black Veterans with Chronic Pain: a Qualitative Study

BACKGROUND

The COVID-19 pandemic led to significant disruptions in healthcare and rapid increases in virtual healthcare delivery. The full effects of these shifts remain unknown. Understanding effects of these disruptions is particularly relevant for patients with chronic pain, which typically requires consistent engagement in treatment to maximize benefit, and for Black patients, given documented racial disparities in pain treatment and telehealth delivery.

OBJECTIVE

To understand how Black patients with chronic pain experienced pandemic-related changes in healthcare delivery.

DESIGN

In-depth, semi-structured qualitative interviews PARTICIPANTS: Black veterans with chronic pain.

KEY RESULTS

Participants described decreased ability to self-manage their chronic pain, obtain nonpharmacological services such as physical therapy, see their primary care providers, and schedule surgery. Most did not believe telehealth met their needs, describing feeling inadequately assessed for their pain and noting that beyond renewing prescriptions, telehealth visits were not that useful. Some believed their communication with their providers suffered from a lack of in-person contact. Others, however, were willing to accept this tradeoff to prevent possible exposure to COVID-19, and some appreciated the convenience of being able to access healthcare from home.

CONCLUSIONS

Black patients with chronic pain described mostly negative effects from the shift to telecare after the pandemic's onset. Given existing disparities and likely persistence of virtual care, research on the longer-term effects of virtual pain care for Black patients is needed.

Evaluation of disparities in impact of mental health intensive case management on 6-month symptoms, functioning, and quality of life between black and white veterans diagnosed with schizophrenia

BACKGROUND

Substantial health disparities have been reported between Black and White Americans diagnosed with schizophrenia. The nature and extent of these disparities among individuals receiving services in an equal-access health care system remains understudied.

PURPOSE AND AIMS

The purpose of this study was to examine disparities in enrollment characteristics, service delivery and clinical outcomes between Black and White veterans diagnosed with schizophrenia who received care in the Veterans Health Administration (VHA), an equal-access health care system.

METHODS

National program evaluation data from the VHA Intensive Community Mental Health Recovery (ICMHR) program were used to evaluate disparities between 2436 Black and 3565 White veterans who enrolled between 1999 and 2013. Veterans and case managers completed measures of sociodemographic factors, clinical history, clinical characteristics, and justice system involvement at enrollment and six months. Chi square and ANOVAs were used to evaluate enrollment and service delivery differences. Six-month changes were evaluated using multiple regression controlling for potentially confounding baseline characteristics. Effect sizes were evaluated with Cohen's d.

RESULTS

Results indicated differences between Black and White veterans in clinical history, justice system involvement, and clinical characteristics at enrollment. Minimal differences in service delivery were noted and longitudinal analyses revealed no significant differences between Black and White veterans on the majority of outcomes.

CONCLUSION

Fewer racial disparities in service use and outcomes were observed in ICMHR than in standard non-VA clinic settings. This study demonstrates that disparities may emerge more strongly from systemic rather than individual-level differences.

Exploring racial/ethnic disparities in rehabilitation outcomes after TBI: A veterans affairs model systems study

BACKGROUND

Almost one-third of the U.S. military population is comprised of service members and veterans (SMVs) of color. Research suggests poorer functional and psychosocial outcomes among Black and Hispanic/Latine vs. White civilians following traumatic brain injury (TBI).

OBJECTIVE

This study examined racial/ethnic differences in 5-year functional independence and life satisfaction trajectories among SMVs who had undergone acute rehabilitation at one of five VA TBI Model Systems (TBIMS) Polytrauma Rehabilitation Centers (PRCs).

METHODS

Differences in demographic and injury-related factors were assessed during acute rehabilitation among White (n = 663), Black (n = 89) and Hispanic/Latine (n = 124) groups. Functional Independence Measure (FIM) Motor, FIM Cognitive, and Satisfaction with Life Scale (SWLS) scores were collected at 1, 2, and 5 years after injury. Racial/ethnic comparisons in these outcome trajectories were made using hierarchical linear modeling.

RESULTS

Black SMVs were less likely than White and Hispanic/Latine SMVs to have been deployed to a combat zone; there were no other racial/ethnic differences in any demographic or injury-related variable assessed. In terms of outcomes, no racial/ethnic differences emerged in FIM Motor, FIM cognitive, or SWLS trajectories.

CONCLUSION

The absence of observable racial/ethnic differences in 5-year outcome trajectories after TBI among SMVs from VA TBIMS PRCs contrasts sharply with previous research identifying disparities in these same outcomes and throughout the larger VA health care system. Individuals enrolled in VA PRCs are likely homogenized on key social determinants of health that would otherwise contribute to racial/ethnic disparities in outcome trajectories.

Conceptualizing the Carrying Function of Community Advisory Boards

Community Advisory Boards (CABs) often, “carry” important ideas and concepts for the larger organization of which they are a part. The word “carry” in this context, means that a person or group expresses verbal and nonverbal messages that inform others of what the institution acknowledges, and also what it cannot bear to feel or talk about. These expressions may include attitudes and expectations, values, risks, or disowned features and qualities. A group can contain, “carry,” and express formal, informal, and unconscious issues for a department or system. In this article, we situate our theoretical underpinning of this carrying function by relying on a number of literatures: identified patient, splitting and projection, parallel process, and container and contained. Specifying and examining the dynamics of what CABs carry for an institution can prevent common pitfalls for these groups, such as mistrust, feelings of disrespect, lack of productivity, and thwarted expectations.

Inclusive Mentorship and Sponsorship

Mentorship and sponsorship are part of academia because they are vital for professional and personal development. Inclusive mentorship is defined as mentoring across differences. It highlights the need of all mentors to be well-versed culturally and to recognize and circumvent bias and microaggressions. Inclusive mentorship can also elevate underrepresented populations in medicine and create intercultural relationships that also benefit the relationships we have with our diversifying patient populations. There are still several barriers prohibiting inclusive mentorship from being widely understood and employed. This article discusses the importance of and techniques for improving inclusive mentorship.

Differences in chronic pain care receipt among veterans from differing racialized groups and the impact of rural versus urban residence

PURPOSE

The current study aimed to identify differences in Veterans Affairs (VA) chronic pain care for Black, Asian, and Hispanic Americans, compared to non-Hispanic White Americans, and examine the intersection of race and rurality.

METHODS

Using national administrative data, all veterans who presented to the VA for chronic pain in 2018 were included. Demographic and comorbidity variables were built from 2018 data and health care utilization variables from 2019 data. Multivariate log-binomial regression models examined differences between racialized groups, and interactions with rural/urban residence, for each health care utilization variable.

FINDINGS

The full cohort included 2,135,216 veterans with chronic pain. There were no differences between racialized groups in pain-related primary care visits. Black Americans were less likely to receive pain clinic visits (aRR = 0.87, CI: 0.86-0.88). Rurality further decreased the likelihood of Black Americans visiting a pain clinic. Black, Hispanic, and Asian Americans were more likely to receive pain-related physical therapy visits relative to White Americans. Black and Hispanic Americans were more likely to present to emergency/urgent care for chronic pain. While there were no differences in pain-related primary care visits, the decreased likelihood of pain clinic visits and increased use of emergency department/urgent care among Black Americans could indicate inadequate management of chronic pain.

CONCLUSIONS

Tailored strategies are needed to provide equitable care that meets the needs of patients from racialized groups while accounting for systemic and cultural factors.

Oncology distress screening within predominately Black Veterans: Outcomes on supportive care utilization, hospitalizations, and mortality

BACKGROUND

We evaluated whether patients' initial screening symptoms were related to subsequent utilization of supportive care services and hospitalizations, and whether patient-level demographics, symptoms, hospitalizations, and supportive care service utilization were associated with mortality in primarily low-income, older, Black Veterans with cancer.

METHODS

This quality improvement project created collaborative clinics to conduct cancer distress screenings and refer to supportive care services at an urban, VA medical center. All patients completed a distress screen with follow-up screening every 3 months. Supportive care utilization, hospitalization rates, and mortality were abstracted through medical records. Poisson regression models and cox proportional hazard models were utilized.

RESULTS

Five hundred and eighty five screened patients were older (m = 72), mostly Black 70% (n = 412), and had advanced cancer 54%. Fifty-eight percent (n = 340) were screened only once with 81% (n = 470) receiving ≥1 supportive care service and 51.5% (n = 297) being hospitalized ≥1 time 18 months following initial screen. Symptom severity was significantly related to number of hospitalizations. Low mood was significantly related to higher supportive services (p < 0.001), but not hospitalizations (p ≥ 0.52). Pain, fatigue, physical function, nutrition, and physical symptoms were significantly associated with more supportive services and hospitalizations (p < 0.01). Twenty percent (n = 168) died; Veterans who were Black, had lower stage cancers, better physical health, and utilized less supportive care services had lower odds of mortality (p ≤ 0.01).

CONCLUSION

Individuals with elevated distress needs and those reporting lower physical function utilized more supportive care services and had higher hospitalization rates. Lower physical function, greater supportive care use, higher stage cancer, and being non-Black were associated with higher odds of death.

Racial differences in persistence to secondary prevention medication regimens after ischemic stroke

BACKGROUND

Prior stroke is one of the biggest risk factors for future stroke events. Effective secondary prevention medication regimens can dramatically reduce recurrent stroke risk. Guidelines recommend the use of antithrombotic, antihypertensive and lipid-lowering medications after stroke. Medication adherence is known to be better in the presence of a caregiver but long-term adherence after stroke is unknown and disparities may persist.

METHODS

We examined the effects of race and sex on baseline prescription and maintenance of secondary prevention regimens in the presence of a caregiver using the Caring for Adults Recovering from the Effects of Stroke (CARES) study, an ancillary study of the national REasons for Geographic and Racial Differences in Stroke (REGARDS).

RESULTS

Incident ischemic stroke survivors (N = 172; 36% Black) with family caregivers had medications recorded at hospital discharge and on average 9.8 months later during a home visit. At discharge, antithrombotic prescription (95.9%), lipid-lowering medications (78.8%) and antihypertensives (89.9%) were common and there were no race or sex differences in discharge prescription rates. One year later, medication persistence had fallen to 86.6% for antithrombotics (p = 0.002) and 69.8% for lipid lowering (p = 0.008) but increased to 93.0% for antihypertensives (p = 0.30). Blacks were more likely to have discontinued antithrombotics than Whites (18.3% v 7.7%, p = 0.04). No significant differences in persistence were seen with age, sex, income, depression, or cognitive impairment.

CONCLUSIONS

Medication persistence was high in this sample, likely due to the presence of a caregiver. In our cohort, despite similar prescription rates at the time of hospital discharge, Black stroke survivors were more than twice as likely to stop antithrombotics than Whites. The effect of changes in patterns of medication usage on health outcomes in Black stroke survivors warrants continued investigation.

Psychosocial Predictors of Chronic Musculoskeletal Pain Outcomes and their Contextual Determinants Among Black Individuals: A Narrative Review

Black communities are disproportionally affected by Chronic Musculoskeletal Pain (CMP), but little is known about the psychological predictors of CMP outcomes and their contextual determinants among Black individuals. To address this gap, we conducted a narrative review of extant literature to (1) report the major conceptual models mentioned in prior work explaining the link between contextual determinants and psychological responses to pain among Black individuals with CMP; and (2) describe psychological factors related to CMP outcomes in this population that are highlighted in the literature. We searched 4 databases (APA PsycNet, PubMed/MEDLINE, Scopus, and Google Scholar) using the following search terms: musculoskeletal pain, chronic pain, mental health, psychological, coping, health disparities, contextual factors, conceptual models, psychosocial, Black, African American, pain, disability, and outcomes. We illustrate 3 relevant conceptual models - socioecological, cumulative stress, and biopsychosocial - related to contextual determinants and several psychological factors that influence CMP outcomes among Black individuals: (1) disproportionate burden of mental health and psychiatric diagnoses, (2) distinct coping strategies, (3) pain-related perceived injustice and perceived racial/ethnic discrimination, and (4) preferences and expectations related to seeking and receiving pain care. The detailed clinical and research implications could serve as a blueprint for the providers and clinical researchers to address health disparities and improve care for Black individuals with CMP. PERSPECTIVE: This narrative review illustrates conceptual models explaining the link between contextual determinants and psychological responses to pain among Black individuals with chronic musculoskeletal pain. We discuss 3 relevant conceptual models - socioecological, cumulative stress, biopsychosocial -, and 4 psychological factors: disproportionate burden of mental health, distinct coping strategies, perceived injustice/discrimination, preferences/expectations.

Optimizing Data on Race and Ethnicity for Veterans Affairs Patients

INTRODUCTION

Maintaining accurate race and ethnicity data among patients of the Veterans Affairs (VA) healthcare system has historically been a challenge. This work expands on previous efforts to optimize race and ethnicity values by combining multiple VA data sources and exploring race- and ethnicity-specific collation algorithms.

MATERIALS AND METHODS

We linked VA patient data from 2000 to 2018 with race and ethnicity data from four administrative and electronic health record sources: VA Medical SAS files (MedSAS), Corporate Data Warehouse (CDW), VA Centers for Medicare extracts (CMS), and VA Defense Identity Repository Data (VADIR). To assess the accuracy of each data source, we compared race and ethnicity values to self-reported data from the Survey of Health Experiences of Patients (SHEP). We used Cohen's Kappa to assess overall (holistic) source agreement and positive predictive values (PPV) to determine the accuracy of sources for each race and ethnicity separately.

RESULTS

Holistic agreement with SHEP data was excellent (K > 0.80 for all sources), while race- and ethnicity-specific agreement varied. All sources were best at identifying White and Black users (average PPV = 0.94, 0.93, respectively). When applied to the full VA user population, both holistic and race-specific algorithms substantially reduced unknown values, as compared to single-source methods.

CONCLUSIONS

Combining multiple sources to generate race and ethnicity values improves data accuracy among VA patients. Based on the overall agreement with self-reported data, we recommend using non-missing values from sources in the following order to fill in race values-SHEP, CMS, CDW, MedSAS, and VADIR-and in the following order to fill in ethnicity values-SHEP, CDW, MedSAS, VADIR, and CMS.

Communication and Activation in Pain to Enhance Relationships and Treat Pain with Equity (COOPERATE): Rationale, study design, methods, and sample characteristics

BACKGROUND

Chronic pain is associated with profound negative effects, and racial disparities are well-documented in chronic pain treatment. In addition, Black patients report poorer communication with providers and exhibit lower levels of patient activation (self-management self-efficacy) than White patients. Although the causes of healthcare disparities are complex and require intervention at multiple levels, empowering patients is one critical path to achieving health equity. The current study is a coaching intervention focused on increasing patient activation and building communication skills for Black patients with chronic pain.

METHODS

In this randomized controlled trial, 250 Black patients with chronic pain were randomized to either the coaching intervention or an attention control arm. Intervention patients attended 6 telephone-delivered individual coaching sessions over 12 weeks. Coaching focused on clarifying and prioritizing goals and on communication skills, such as agenda setting. The primary outcome is patient activation. Secondary outcomes include communication self-efficacy, pain intensity and interference, and psychological functioning.

DISCUSSION

Having the knowledge and confidence to participate in one's pain care, coupled with the skills needed to effectively communicate with providers, is essential to optimize chronic pain care. This is particularly important for Black patients who often experience lower quality pain care. Interventions such as COOPERATE hold promise for helping patients to acquire the requisite tools to take greater control of their chronic pain care.

Disruptive Dizziness Among Post-9/11 Veterans With Deployment-Related Traumatic Brain Injury

OBJECTIVE

To identify disruption due to dizziness symptoms following deployment-related traumatic brain injury (TBI) and factors associated with receiving diagnoses for these symptoms.

SETTING

Administrative medical record data from the Department of Veterans Affairs (VA).

PARTICIPANTS

Post-9/11 veterans with at least 3 years of VA care who reported at least occasional disruption due to dizziness symptoms on the comprehensive TBI evaluation.

DESIGN

A cross-sectional, retrospective, observational study.

MAIN MEASURES

International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes of dizziness, vestibular dysfunction, and other postconcussive conditions; neurobehavioral Symptom Inventory.

RESULTS

Increased access to or utilization of specialty care at the VA was significant predictors of dizziness and/or vestibular dysfunction diagnoses in the fully adjusted model. Veterans who identified as Black non-Hispanic and those with substance use disorder diagnoses or care were substantially less likely to receive dizziness and vestibular dysfunction diagnoses.

CONCLUSIONS

Access to specialty care was the single best predictor of dizziness and vestibular dysfunction diagnoses, underscoring the importance of facilitating referrals to and utilization of specialized, comprehensive clinical facilities or experts for veterans who report disruptive dizziness following deployment-related TBI. There is a clear need for an evidence-based pathway to address disruptive symptoms of dizziness, given the substantial variation in audiovestibular tests utilized by US providers by region and clinical specialty. Further, the dearth of diagnoses among Black veterans and those in more rural areas underscores the potential for enhanced cultural competency among providers, telemedicine, and patient education to bridge existing gaps in the care of dizziness.

Patients undergoing colorectal surgery at a Veterans Affairs Hospital do not experience racial disparity in length of stay either before or after implementing an enhanced recovery pathway

Background

Enhanced Recovery Pathways (ERP) have been shown to reduce racial disparities following surgery. The objective of this study is to determine whether ERP implementation mitigates racial disparities at a Veterans Affairs Hospital.

Methods

A retrospective cohort study was conducted using data obtained from the Veterans Affairs Surgical Quality Improvement Program. All patients undergoing elective colorectal surgery following ERP implementation were included. Current procedural terminology (CPT) codes were used to identify patients who underwent similar procedures prior to ERP implementation.

Results

Our study included 417 patients (314 pre-ERP vs. 103 ERP), 97.1% of which were male, with an average age of 62.32 (interquartile range (IQR): 25–90). ERP patients overall had a significantly shorter post-operative length of stay (pLOS) vs. pre-ERP patients (median 4 days (IQR: 3–6.5) vs. 6 days (IQR: 4–9) days (p < 0.001)). Within the pre-ERP group, median pLOS for both races was 6 days (IQR: 4–6; p < 0.976) and both groups experienced a decrease in median pLOS (4 vs. 6 days; p < 0.009 and p < 0.001) following ERP implementation.

Conclusions

Racial disparities did not exist in patients undergoing elective surgery at a single VA Medical Center. Implementation of an ERP significantly reduced pLOS for black and white patients.

Racial and ethnic differences in the adoption of opportunistic salpingectomy for ovarian cancer prevention in the United States

BACKGROUND

Clinicians in the United States have rapidly adopted opportunistic salpingectomy for ovarian cancer prevention. However, little is known about racial and ethnic differences in opportunistic salpingectomy adoption. Surgical innovations in gynecology may be adopted differentially across racial and ethnic groups, exacerbating current disparities in quality of care.

OBJECTIVE

This study aimed to evaluate racial and ethnic differences in opportunistic salpingectomy adoption across inpatient and outpatient settings and assess the effect of national guidelines supporting opportunistic salpingectomy use on these differences.

STUDY DESIGN

A sample of 650,905 women aged 18 to 50 years undergoing hysterectomy with ovarian conservation or surgical sterilization from 2011 to 2018 was identified using the Premier Healthcare Database, an all-payer hospital administrative database, including more than 700 hospitals across the United States. The association between race and ethnicity and opportunistic salpingectomy use was examined using multivariable-adjusted mixed-effects log-binomial regression models accounting for hospital-level clustering. Models included race and ethnicity by year of surgery (2011-2013 [before guideline] and 2014-2018 [after guideline]) interaction term to test whether racial and ethnic differences in opportunistic salpingectomy adoption changed with the release of national guidelines supporting opportunistic salpingectomy use.

RESULTS

From 2011 to 2018, 82,792 women underwent hysterectomy and opportunistic salpingectomy (non-Hispanic White, 60.3%; non-Hispanic Black, 18.8%; Hispanic, 12.2%; non-Hispanic other race, 8.7%) and 23,398 women underwent opportunistic salpingectomy for sterilization (non-Hispanic White, 64.7%; non-Hispanic Black, 10.8%; Hispanic, 16.7%; non-Hispanic other race, 7.8%). The proportion of hysterectomy procedures involving an opportunistic salpingectomy increased from 6.3% in 2011 to 59.7% in 2018 (9.5-fold increase), and the proportion of sterilization procedures involving an opportunistic salpingectomy increased from 0.7% in 2011 to 19.4% in 2018 (27.7-fold increase). In multivariable-adjusted models, non-Hispanic Black (risk ratio, 0.94; 95% confidence interval, 0.92-0.97), Hispanic (risk ratio, 0.98; 95% confidence interval, 0.95-1.00), and non-Hispanic other race women (risk ratio, 0.93; 95% confidence interval, 0.90-0.96) were less likely to undergo hysterectomy and opportunistic salpingectomy than non-Hispanic White women. A significant interaction between race and ethnicity and year of surgery was noted in non-Hispanic Black compared with non-Hispanic White women (P<.001), with a reduction in differences in hysterectomy and opportunistic salpingectomy use after national guideline release (risk ratio_2011-2013, 0.80 [95% confidence interval, 0.73-0.88]; risk ratio_2014-2018, 0.98 [95% confidence interval, 0.95-1.01]). Moreover, non-Hispanic Black women were less likely to undergo an opportunistic salpingectomy for sterilization than non-Hispanic White women (risk ratio, 0.91; 95% confidence interval, 0.88-0.95), with no difference by year of surgery (P=.62). Stratified analyses by hysterectomy route and age at surgery revealed similar results.

CONCLUSION

Although opportunistic salpingectomy for ovarian cancer prevention has been rapidly adopted in the United States, our findings suggested that its adoption has not been equitable across racial and ethnic groups. Non-Hispanic Black, Hispanic, and non-Hispanic other race women were less likely to undergo opportunistic salpingectomy than non-Hispanic White women even after adjusting for sociodemographic, clinical, procedural, hospital, and provider characteristics. These differences persisted after the release of national guidelines supporting opportunistic salpingectomy use. Future research should focus on understanding the reasons for these differences to inform interventions that promote equity in opportunistic salpingectomy use.

Demographic Differences Among US Department of Veterans Affairs Patients Referred for Genetic Consultation to a Centralized VA Telehealth Program, VA Medical Centers, or the Community

IMPORTANCE

Telehealth enables access to genetics clinicians, but impact on care coordination is unknown.

OBJECTIVE

To assess care coordination and equity of genetic care delivered by centralized telehealth and traditional genetic care models.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study included patients referred for genetic consultation from 2010 to 2017 with 2 years of follow-up in the US Department of Veterans Affairs (VA) health care system. Patients were excluded if they were referred for research, cytogenetic, or infectious disease testing, or if their care model could not be determined.

EXPOSURES

Genetic care models, which included VA-telehealth (ie, a centralized team of genetic counselors serving VA facilities nationwide), VA-traditional (ie, a regional service by clinical geneticists and genetic counselors), and non-VA care (ie, community care purchased by the VA).

MAIN OUTCOMES AND MEASURES

Multivariate regression models were used to assess associations between patient and consultation characteristics and the type of genetic care model referral; consultation completion; and having 0, 1, or 2 or more cancer surveillance (eg, colonoscopy) and risk-reducing procedures (eg, bilateral mastectomy) within 2 years following referral.

RESULTS

In this study, 24 778 patients with genetics referrals were identified, including 12 671 women (51.1%), 13 193 patients aged 50 years or older (53.2%), 15 639 White patients (63.1%), and 15 438 patients with cancer-related referrals (62.3%). The VA-telehealth model received 14 580 of the 24 778 consultations (58.8%). Asian patients, American Indian or Alaskan Native patients, and Hawaiian or Pacific Islander patients were less likely to be referred to VA-telehealth than White patients (OR, 0.54; 95% CI, 0.35-0.84) compared with the VA-traditional model. Completing consultations was less likely with non-VA care than the VA-traditional model (OR, 0.45; 95% CI, 0.35-0.57); there were no differences in completing consultations between the VA models. Black patients were less likely to complete consultations than White patients (OR, 0.84; 95% CI, 0.76-0.93), but only if referred to the VA-telehealth model. Patients were more likely to have multiple cancer preventive procedures if they completed their consultations (OR, 1.55; 95% CI, 1.40-1.72) but only if their consultations were completed with the VA-traditional model.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, the VA-telehealth model was associated with improved access to genetics clinicians but also with exacerbated health care disparities and hindered care coordination. Addressing structural barriers and the needs and preferences of vulnerable subpopulations may complement the centralized telehealth approach, improve care coordination, and help mitigate health care disparities.

Association of Vitamin D Status and COVID-19-Related Hospitalization and Mortality

BACKGROUND

The relationship between vitamin D status and COVID-19-related clinical outcomes is controversial. Prior studies have been conducted in smaller, single-site, or homogeneous populations limiting adjustments for social determinants of health (race/ethnicity and poverty) common to both vitamin D deficiency and COVID-19 outcomes.

OBJECTIVE

To evaluate the dose-response relationship between continuous 25(OH)D and risk for COVID-19-related hospitalization and mortality after adjusting for covariates associated with both vitamin D deficiency and COVID-19 outcomes.

DESIGN

Retrospective cohort study.

PATIENTS

Veteran patients receiving care in US Department of Veteran Affairs (VA) health care facilities with a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test and a blood 25(OH)D test between February 20, 2020, and November 8, 2020, followed for up to 60 days.

MAIN MEASURES

Exposure was blood 25(OH)D concentration ascertained closest to and within 15 to 90 days preceding an index positive SARS-CoV-2 test. Co-primary study outcomes were COVID-19-related inpatient hospitalization requiring airborne, droplet, contact, or other isolation and mortality ascertained within 60 days of an index positive SARS-CoV-2 test.

KEY RESULTS

Of 4,599 veterans with a positive SARS-CoV-2 test, vitamin D deficiency (< 20 ng/mL) was identified in 665 (14.5%); 964 (21.0%) were hospitalized; and 340 (7.4%) died. After adjusting for all covariates, including race/ethnicity and poverty, there was a significant independent inverse dose-response relationship between increasing continuous 25(OH)D concentrations (from 15 to 60 ng/mL) and decreasing probability of COVID-19-related hospitalization (from 24.1 to 18.7%, p=0.009) and mortality (from 10.4 to 5.7%, p=0.001). In modeling 25(OH)D as a log-transformed continuous variable, the greatest risk for hospitalization and death was observed at lower 25(OH)D concentrations.

CONCLUSIONS

Continuous blood 25(OH)D concentrations are independently associated with COVID-19-related hospitalization and mortality in an inverse dose-response relationship in this large racially and ethnically diverse cohort of VA patients. Randomized controlled trials are needed to evaluate the impact of vitamin D supplementation on COVID-19-related outcomes.

Racial Disparities in 30-Day Outcomes After Colorectal Surgery in an Integrated Healthcare System

BACKGROUND

Racial disparities in colorectal surgery outcomes have been studied extensively in the USA, and access to healthcare resources may contribute to these differences. The Veterans Health Administration (VHA) is the largest integrated healthcare network in the USA with the potential for equal access care to veterans. The objective of this study is to evaluate the VHA for the presence of racial disparities in 30-day outcomes of patients that underwent colorectal resection.

METHODS

Colon and rectal resections from 2008 to 2019 were reviewed retrospectively using the Veterans Affairs Surgical Quality Improvement Program database. Patients were categorized by race and ethnicity. Multivariable analysis was used to compare 30-day outcomes. Cases with "unknown/other/declined to answer" race/ethnicity were excluded.

RESULTS

Thirty-six-thousand-nine-hundred-sixty-nine cases met inclusion criteria: 27,907 (75.5%) Caucasian, 6718 (18.2%) African American, 2047 (5.5%) Hispanic, and 290 (0.8%) Native American patients. There were no statistically significant differences in overall complication incidence or mortality between all cohorts. Compared to Caucasian race, African American patients had longer mean length of stay (10.7 days vs. 9.7 days; p < 0.001). Compared to Caucasian race, Hispanic patients had higher odds of pulmonary-specific complications (adjusted odds ratio with 95% confidence interval = 1.39 [1.17-1.64]; p < 0.001).

CONCLUSIONS

The VHA provides the benefits of integrated healthcare and access, which may explain the improvements in racial disparities compared to existing literature. However, some racial disparities in clinical outcomes still persisted in this analysis. Further efforts beyond healthcare access are needed to mitigate disparities in colorectal surgery.

Racial Disparities in Clinical Outcomes of Veterans Affairs Residential PTSD Treatment Between Black and White Veterans

OBJECTIVE

Racial disparities across various domains of health care are a long-standing public health issue that affect a variety of clinical services and health outcomes. Mental health research has shown that prevalence rates of posttraumatic stress disorder (PTSD) are high for Black veterans compared with White veterans, and some studies suggest poorer clinical outcomes for Black veterans with PTSD. The aim of this study was to examine the impact of racial disparities longitudinally in the U.S. Department of Veterans Affairs (VA) residential rehabilitation treatment programs (RRTPs).

METHODS

Participants included 2,870 veterans treated nationally in VA PTSD RRTPs in fiscal year 2017. Veterans provided demographic data upon admission to the program. Symptoms of PTSD and depression were collected at admission, discharge, and 4-month follow-up. Hierarchical linear modeling was used to examine symptom change throughout and after treatment.

RESULTS

Black veterans experienced attenuated PTSD symptom reduction during treatment as well as greater depression symptom recurrence 4 months after discharge, relative to White veterans.

CONCLUSIONS

This study adds to the body of literature that has documented poorer treatment outcomes for Black compared with White veterans with PTSD. Although both Black and White veterans had an overall reduction in symptoms, future research should focus on understanding the causes, mechanisms, and potential solutions to reduce racial disparities in mental health treatment.

Preventing Unequal Health Outcomes in COVID-19: A Systematic Review of Past Interventions

Background: We sought to identify interventions that reduced disparities in health outcomes in infectious disease outbreaks or natural disasters in the United States to understand whether these interventions could reduce health disparities in the current COVID-19 pandemic. Methods: We searched MEDLINE and other databases to May 2020 to find studies that examined interventions to mitigate health inequalities in previous infectious disease pandemics or disasters. We assessed study quality using the Newcastle-Ottawa Scale and the Critical Appraisal Skills Program (CASP) Checklist for Qualitative Studies. Results: We included 14 articles (12 studies) and 5 Centers for Disease Control (CDC) stakeholder meeting articles on pandemic influenza preparedness in marginalized populations. Studies called for intervention and engagement before pandemic or disaster onset. Several studies included interventions that could be adapted to COVID-19, including harnessing technology to reach disadvantaged populations, partnering with trusted community liaisons to deliver important messaging around disease mitigation, and using culturally specific communication methods and messages to best reach marginalized groups. Discussion: To our knowledge this is the first systematic review to examine interventions to mitigate health inequities during an infectious disease pandemic. However, given that we identified very few disparities-focused infectious disease intervention studies, we also included studies from the disaster response literature, which may not be as generalizable to the current context of COVID-19. Overall, community outreach and tailored communication are essential in disease mitigation. More research is needed to evaluate systemic interventions that target the distal determinants of poor health outcomes among marginalized populations during pandemics and natural disasters.

Addressing Racism in Preventive Services: Methods Report to Support the US Preventive Services Task Force

IMPORTANCE

In January 2021, the US Preventive Services Task Force (USPSTF) issued a values statement that acknowledged systemic racism and included a commitment to address racism and health equity in recommendations for clinical preventive services.

OBJECTIVES

To articulate the definitional and conceptual issues around racism and health inequity and to describe how racism and health inequities are currently addressed in preventive health.

METHODS

An audit was conducted assessing (1) published literature on frameworks or policy and position statements addressing racism, (2) a subset of cancer and cardiovascular topics in USPSTF reports, (3) recent systematic reviews on interventions to reduce health inequities in preventive health or to prevent racism in health care, and (4) health care-relevant professional societies, guideline-making organizations, agencies, and funding bodies to gather information about how they are addressing racism and health equity.

FINDINGS

Race as a social category does not have biological underpinnings but has biological consequences through racism. Racism is complex and pervasive, operates at multiple interrelated levels, and exerts negative effects on other social determinants and health and well-being through multiple pathways. In its reports, the USPSTF has addressed racial and ethnic disparities, but not racism explicitly. The systematic reviews to support the USPSTF include interventions that may mitigate health disparities through cultural tailoring of behavioral interventions, but reviews have not explicitly addressed other commonly studied interventions to increase the uptake of preventive services or foster the implementation of preventive services. Many organizations have issued recent statements and commitments around racism in health care, but few have provided substantive guidance on operational steps to address the effects of racism. Where guidance is unavailable regarding the proposed actions, it is principally because work to achieve them is in very early stages. The most directly relevant and immediately useful guidance identified is that from the GRADE working group.

CONCLUSIONS AND RELEVANCE

This methods report provides a summary of issues around racism and health inequity, including the status of how these are being addressed in preventive health.

The Association Between Veteran Status and Obesity Differs Across Race/Ethnicity

PURPOSE

This study aims to evaluate the interaction between veteran status and race/ethnicity on obesity status.

DESIGN

Cross-sectional survey.

SETTING

The 2013-2017 National Health Interview Survey.

SAMPLE

A total of 151,765 adults (8.62% veterans and 91.38 nonveterans) with 69.30% identifying as White, 13.05% identifying as Hispanic, 12.57% identifying as Black, and 5.08% identifying as Asian.

MEASURES

Obesity status (measured using self-reported body mass index), race/ethnicity, survey year, age, marital status, educational attainment, federal poverty level, health insurance, type of insurance, self-reported health status, and whether participant had a usual care source.

ANALYSIS

Weighted logistic regression analysis.

RESULTS

In a fully adjusted model, there was no evidence that veterans overall had higher odds of obesity compared to nonveterans (adjusted odd ratio (aOR): 1.05, 95% CI: .99, 1.11). White veterans had lower odds of obesity compared to White nonveterans (OR: .93, 95% CI: .87, .98). Hispanic veterans had higher odds of obesity compared to Hispanic nonveterans (aOR: 1.53, 95% CI: 1.23, 1.90). There was no evidence of an association between veteran status and obesity status for Black and Asian adults.

CONCLUSIONS

Effectual prevention strategies are needed to decrease obesity risks among active and retired Hispanic veterans.

Racial/Ethnic Differences in 30-Day Mortality for Heart Failure and Pneumonia in the Veterans Health Administration Using Claims-based, Clinical, and Social Risk-adjustment Variables

BACKGROUND

Prior studies have identified lower mortality in Black Veterans compared with White Veterans after hospitalization for common medical conditions, but these studies adjusted for comorbid conditions identified in administrative claims.

OBJECTIVES

The objectives of this study were to compare mortality for non-Hispanic White (hereafter, "White"), non-Hispanic Black (hereafter, "Black"), and Hispanic Veterans hospitalized for heart failure (HF) and pneumonia and determine whether observed mortality differences varied according to whether claims-based comorbid conditions and/or clinical variables were included in risk-adjustment models.

RESEARCH DESIGN

This was an observational study.

SUBJECTS

The study cohort included 143,520 admissions for HF and 127,782 admissions for pneumonia for Veterans hospitalized in 132 Veterans Health Administration (VA) Medical Centers between January 2009 and September 2015.

MEASURES

The primary independent variable was racial/ethnic group (ie, Black, Hispanic, and non-Hispanic White), and the outcome was all-cause mortality 30 days following admission. To compare mortality by race/ethnicity, we used logistic regression models that included different combinations of claims-based, clinical, and sociodemographic variables. For each model, we estimated the average marginal effect (AME) for Black and Hispanic Veterans relative to White Veterans.

RESULTS

Among the 143,520 (127,782) hospitalizations for HF (pneumonia), the average patient age was 71.6 (70.9) years and 98.4% (97.1%) were male. The unadjusted 30-day mortality rates for HF (pneumonia) were 7.2% (11.0%) for White, 4.1% (10.4%) for Black and 8.4% (16.9%) for Hispanic Veterans. Relative to White Veterans, when only claims-based variables were used for risk adjustment, the AME (95% confidence interval) for the HF [pneumonia] cohort was -2.17 (-2.45, -1.89) [0.08 (-0.41, 0.58)] for Black Veterans and 1.32 (0.49, 2.15) [4.51 (3.65, 5.38)] for Hispanic Veterans. When clinical variables were incorporated in addition to claims-based ones, the AME, relative to White Veterans, for the HF [pneumonia] cohort was -1.57 (-1.88, -1.27) [-0.83 (-1.31, -0.36)] for Black Veterans and 1.50 (0.71, 2.30) [3.30 (2.49, 4.11)] for Hispanic Veterans.

CONCLUSIONS

Compared with White Veterans, Black Veterans had lower mortality, and Hispanic Veterans had higher mortality for HF and pneumonia. The inclusion of clinical variables into risk-adjustment models impacted the magnitude of racial/ethnic differences in mortality following hospitalization. Future studies examining racial/ethnic disparities should consider including clinical variables for risk adjustment.
