Evidence Review-Social Determinants of Health for Veterans

Interactive Relations of Body Mass Index, Cardiorespiratory Fitness, and Sex to Cognitive Function in Older Adults

OBJECTIVE

The course of cognitive aging is influenced by multiple health factors. This cross-sectional study investigated the interactive relations between body mass index (BMI), maximum oxygen consumption (VO2max), and sex on neuropsychological outcomes in community-dwelling predominantly older adults.

METHODS

Participants were 164 healthy adults [M (SD) = 64.6 (12.5) years, 56% men, 87% white] who participated in an investigation of cardiovascular risk factors and brain health. Multivariable regression analysis, adjusted for age, education, ethnicity, smoking, alcohol consumption, and depression, examined the interactive relations of BMI, VO2max, and sex to multiple neuropsychological outcomes.

RESULTS

Significant BMI*VO2max*sex interactions for Grooved Pegboard dominant (p = .019) and nondominant (p = .005) hands revealed that men with lower VO2max (l/min) displayed worse performance with each hand as BMI increased (p's < .02). A significant BMI*sex interaction for Logical Memory-Delayed Recall (p = .036) (after adjustment for blood glucose) showed that men, but not women, with higher BMI demonstrated worse performance (p = .036). Lastly, significant main effects indicated that lower VO2max was related to poorer logical memory, and higher BMI was associated with poorer Trail Making B and Stroop interference scores (p's < .05).

CONCLUSIONS

Among men, higher cardiorespiratory fitness may protect against the negative impact of greater BMI on manual dexterity and motor speed, making VO2max a target for intervention. Higher BMI is further associated with poorer executive function and verbal memory (in men), and lower VO2max is associated with poorer verbal memory.

Neurocognitive function and medical care utilization in Veterans treated for substance use disorder

BACKGROUND

Veterans with substance use disorder (SUD) are at high risk for cognitive problems due to neurotoxic effects of chronic drug and alcohol use coupled in many cases with histories of traumatic brain injury (TBI). These problems may in turn result in proneness to SUD relapse and reduced adherence to medical self-care regimens and therefore reliance on health care systems. However, the direct relationship between cognitive function and utilization of Veterans Health Administration (VHA) SUD and other VHA health care services has not been evaluated. We sought initial evidence as to whether neurocognitive performance relates to repeated health care engagement in Veterans as indexed by estimated VHA care costs.

METHODS

Neurocognitive performance in 76 Veterans being treated for SUD was assessed using CNS-Vital Signs, a commercial computerized cognitive testing battery, and related to histories of outpatient and inpatient/residential care costs as estimated by the VHA Health Economics Resource Center.

RESULTS

After controlling for age, an aggregate metric of overall neurocognitive performance (Neurocognition Index) correlated negatively with total VHA health care costs, particularly with SUD-related outpatient care costs but also with non-mental health-related care costs. Barratt Impulsiveness Scale scores also correlated positively with total VHA care costs.

CONCLUSIONS

In Veterans receiving SUD care, higher impulsivity and lower cognitive performance were associated with greater health care utilization within the VHA system. This suggests that veterans with SUD who show lower neurocognitive performance are at greater risk for continued health problems that require healthcare engagement. Cognitive rehabilitation programs developed for brain injury and other neurological conditions could be tried in Veterans with SUD to improve their health outcomes.

Differences by Sexual Orientation in Patient-Centered Care Outcomes for Veterans Utilizing Primary Care Services at the Veterans Health Administration

Purpose: This study examined the differences by sexual orientation in patient-centered care outcomes (including health care experiences and health-related screening) of veterans utilizing Veterans Health Administration (VHA) primary care. Methods: VHA's adapted version of the Consumer Assessment of Healthcare Providers and Systems was used to compare the health care experience of primary care services among sexual minority (SM) and heterosexual veterans. Health care experience measures were dichotomized to "always" versus "less" and stratified by SM status. Health-related screening measures were dichotomous. Survey data were weighted using provided sample weights. Descriptive statistics were performed on sociodemographic characteristics. Logistic regression coefficients were represented as adjusted odds ratios (aORs). A total of 66,348 veterans were included in the analytic sample, of which 2.9% (n = 1,935) identified as SM. Sexual orientation was ascertained by self-report measures by veterans. Results: SM veterans were significantly younger (56.95 years vs. 63.43 years, p < 0.001), were less likely to report that their provider showed respect for what they had to say (aOR: 0.76; 95% confidence interval [CI]: 0.61-0.95), that they were asked about difficulties taking care of their health (aOR: 0.81; 95% CI: 0.67-0.96), and their provider listened carefully to them (aOR: 0.71; 95% CI: 0.57-0.87) compared to heterosexual veterans. Conclusion: Health care experiences differed between SM and heterosexual veterans who sought VHA primary care, suggesting the need to increase provider trainings, which may improve cultural competency and promote a more welcoming and inclusive environment.

ACORN SDOH survey: Terminological representation for use with NLP and CDS

Objective

Social Determinants of Health (SDOH) greatly influence health outcomes. SDOH surveys, such as the Assessing Circumstances & Offering Resources for Needs (ACORN) survey, have been developed to screen for SDOH in Veterans. The purpose of this study is to determine the terminological representation of the ACORN survey, to aid in natural language processing (NLP).

Methods

Each ACORN survey question was read to determine its concepts. Next, Solor was searched for each of the concepts and for the appropriate attributes. If no attributes or concepts existed, they were proposed. Then, each question's concepts and attributes were arranged into subject-relation-object triples.

Results

Eleven unique attributes and 18 unique concepts were proposed. These results demonstrate a gap in representing SDOH with terminologies. We believe that using these new concepts and relations will improve NLP, and thus, the care provided to Veterans.

Relationship of social determinants of health with symptom severity among Veterans and non-Veterans with probable posttraumatic stress disorder or depression

PURPOSE

Social determinants of health (SDoH) refer to the conditions in the environments in which people live that affect health outcomes and risks. SDoH may provide proximal, actionable targets for interventions. This study examined how SDoH are associated with posttraumatic stress disorder (PTSD) and depression symptoms among Veterans and non-Veterans with probable PTSD or depression.

METHODS

Four multiple regressions were conducted. Two multiple regressions with Veterans examined the impact of SDoH on PTSD symptoms and on depression symptoms. Two multiple regressions with non-Veterans examined the impact of SDoH on PTSD symptoms and on depression symptoms. Independent variables included demographic characteristics, adverse experiences (in childhood and adulthood), and SDoH (discrimination, education, employment, economic instability, homelessness, justice involvement, and social support). Correlates that were statistically significant (p < 0.05) and clinically meaningful (rpart >|0.10|) were interpreted.

RESULTS

For Veterans, lower social support (rpart = - 0.14) and unemployment (rpart = 0.12) were associated with greater PTSD symptoms. Among non-Veterans, greater economic instability (rpart = 0.19) was associated with greater PTSD symptoms. In the depression models, lower social support (rpart = - 0.23) and greater economic instability (rpart = 0.12) were associated with greater depression for Veterans, while only lower social support was associated with greater depression for non-Veterans (rpart = - 0.14).

CONCLUSION

Among Veterans and non-Veterans with probable PTSD or depression, SDoH were associated with PTSD and depression symptoms, particularly social support, economic instability, and employment. Beyond direct treatment of mental health symptoms, addressing social support and economic factors such as instability and employment in the context of PTSD and depression are potential intervention targets that would benefit from future research.

The perceived impact of pandemic scale (PIPS): Initial development and examination among U.S. military veterans

The COVID-19 pandemic has had significant impacts, including increases in mental health problems, distress, interpersonal conflict, unemployment, loss of income, housing instability, and food insecurity. Veterans may be particularly vulnerable to such impacts given their burden of mental and physical health problems. Few existing measures assess pandemic impact, and none have been validated for use with Veterans. We developed such a measure (the Perceived Impact of the Pandemic Scale; PIPS) and examined its psychometric performance in a national sample of US Veterans. Survey data from 567 Veterans were collected between 12/2020 and 2/2021. To examine PIPS factor structure, split sample exploratory/confirmatory factor analyses (EFA/CFA) were conducted to identify and test the most plausible model among an initial set of 18 items. Based on tests of factor extraction and factor loadings, 15 items clearly loaded onto three distinct factors. Internal reliability of all factors was ω > 0.8 and CFA model fit was good (χ2(87) = 167.39, p < .001; SRMR = 0.068; RMSEA = 0.060 [95% CI: 0.05, 0.07], CFI = 0.92). Mean factor scores were significantly positively correlated with measures of depression and loneliness, and negatively correlated with perceived social support. Results suggest the PIPS assesses three internally reliable factors comprised of perceived impact of the pandemic on interpersonal relationships, financial impact, and personal health and well-being. Construct validity with US Veterans was supported. The PIPS may be useful for examining the potentially disparate impact of pandemics on different populations. Research is needed to validate the PIPS in non-Veteran populations.

Comparing Quality of Surgical Care Between the US Department of Veterans Affairs and Non-Veterans Affairs Settings: A Systematic Review

In response to concerns about healthcare access and long wait times within the Veterans Health Administration (VA), Congress passed the Choice Act of 2014 and the Maintaining Internal Systems and Strengthening Integrated Outside Networks (MISSION) Act of 2018 to create a program for patients to receive care in non-VA sites of care, paid by VA. Questions remain about the quality of surgical care between these sites in specific and between VA and non-VA care in general. This review synthesizes recent evidence comparing surgical care between VA and non-VA delivered care across the domains of quality and safety, access, patient experience, and comparative cost/efficiency (2015 to 2021). Eighteen studies met the inclusion criteria. Of 13 studies reporting quality and safety outcomes, 11 reported that quality and safety of VA surgical care were as good as or better than non-VA sites of care. Six studies of access did not have a preponderance of evidence favoring care in either setting. One study of patient experience reported VA care as about equal to non-VA care. All 4 studies of cost/efficiency outcomes favored non-VA care. Based on limited data, these findings suggest that expanding eligibility for veterans to get care in the community may not provide benefits in terms of increasing access to surgical procedures, will not result in better quality, and may result in worse quality of care, but may reduce inpatient length of stay and perhaps cost less.

Association between modifiable social determinants and mental health among post-9/11 Veterans: A systematic review

Introduction

As U.S. Veterans reintegrate from active duty to civilian life, many are at risk for negative modifiable social determinants of health. The prevalence of mental health conditions among Veterans is also high. Awareness of the associations between these two factors is growing. This systematic review provides a comprehensive analysis of the current state of knowledge of the associations between modifiable social determinants and mental health among U.S. Veterans.

Methods

The authors systematically searched four databases and identified 28 articles representing 25 unique studies that met inclusion criteria. Findings from the studies were extracted and synthesized on the basis of modifiable social determinants. Study quality and risk of bias were assessed using the Methodological Quality Questionnaire.

Results

The studies identified in the systematic review examined three modifiable social determinants of health: 1) housing stability, 2) employment and finances, and 3) social support. Although the lack of validity for measures of housing stability, employment, and finances compromised study quality, the overall evidence suggests that Veterans with access to supportive social determinants had better mental health status. Evidence was particularly robust for the association between strong social support and lower symptoms of posttraumatic stress disorder.

Discussion

Current evidence suggests the need to consider modifiable social determinants of health when designing mental health interventions. However, more research encompassing a wider range of modifiable social determinants such as food security, education, and transportation and using comprehensive methods and validated instruments is needed. Future research also needs to intentionally include Veterans from diverse racial-ethnic groups.

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.

Veterans Health Administration (VA) vs. Non-VA Healthcare Quality: A Systematic Review

BACKGROUND

The Veterans Health Administration (VA) serves Veterans in the nation's largest integrated healthcare system. VA seeks to provide high quality of healthcare to Veterans, but due to the VA Choice and MISSION Acts, VA increasingly pays for care outside of its system in the community. This systematic review compares care provided in VA and non-VA settings, and includes published studies from 2015 to 2023, updating 2 prior systematic reviews on this topic.

METHODS

We searched PubMed, Web of Science, and PsychINFO from 2015 to 2023 for published literature comparing VA and non-VA care, including VA-paid community care. Records were included at the abstract or full-text level if they compared VA medical care with care provided in other healthcare systems, and included clinical quality, safety, access, patient experience, efficiency (cost), or equity outcomes. Data from included studies was abstracted by two independent reviewers, with disagreements resolved by consensus. Results were synthesized narratively and via graphical evidence maps.

RESULTS

Thirty-seven studies were included after screening 2415 titles. Twelve studies compared VA and VA-paid community care. Most studies assessed clinical quality and safety, and studies of access were second most common. Only six studies assessed patient experience and six assessed cost or efficiency. Clinical quality and safety of VA care was better than or equal to non-VA care in most studies. Patient experience in VA care was better than or equal to experience in non-VA care in all studies, but access and cost/efficiency outcomes were mixed.

DISCUSSION

VA care is consistently as good as or better than non-VA care in terms of clinical quality and safety. Access, cost/efficiency, and patient experience between the two systems are not well studied. Further research is needed on these outcomes and on services widely used by Veterans in VA-paid community care, like physical medicine and rehabilitation.

Prescription Opioid Misuse and Suicidal Behaviors Among US Veterans: A Cross-Sectional Study from the 2015-2019 National Survey on Drug Use and Health

Suicide continues to be a serious public health issue for the US veteran population as its prevalence has skyrocketed over the last 15 years. This cross-sectional study estimates the prevalence of suicidal behaviors and prescription opioid misuse among veterans and identifies associations between suicidal behaviors and misuse of prescription opioids using data from the National Survey on Drug Use and Health. The findings show that approximately 3.7% of all veterans in this sample experienced suicidal behaviors, while nearly 3.0% reported misusing prescription opioids. Veterans who misused prescription opioids had a much higher prevalence of suicidal behaviors (16.3%) than veterans who used prescription opioids without misuse (4.8%) and those who did not use prescription opioids at all (2.5%). Opioid misuse is strongly associated with suicidal behaviors among veterans. Immediate substance use and mental health screenings, upon first contact with a healthcare system, are imperative in preventing and reducing suicide rates within this vulnerable population.

'It Makes You Sit Back and Think Where You Wanna Go': Veteran experiences in virtual whole health peer-led groups

BACKGROUND

The Veterans Health Administration (VHA) is building a Whole Health system of care that aspires to empower and equip each Veteran to pursue a personally meaningful vision of health and well-being. As part of this effort, VHA has developed Taking Charge of My Life and Health (TCMLH), a peer-led, group-based programme that seeks to support Veterans in setting and pursuing health and well-being goals. Prior research showed TCMLH groups to positively impact Veteran outcomes; yet, little is known about Veterans' own experiences and perspectives.

METHODS

We completed semi-structured telephone interviews with 15 Veterans across 8 sites who had participated in TCMLH groups offered by the VHA in the virtual format between Summer 2020 and Fall 2021. Inductive thematic analysis was applied to interview transcripts to generate themes.

FINDINGS

We identified five themes regarding Veterans' experiences with TCMLH: (1) navigating the virtual format; (2) internalizing the value of health engagement; (3) making healthy lifestyle changes; (4) forging social connections; and (5) taking on a more active role in healthcare.

CONCLUSION

Veterans perceived virtual TCMLH groups as meaningful and beneficial, yet also highlighted several challenges. Their perspectives speak to the need to supplement time-limited programmes like TCMLH with ongoing, community-based support. Virtual group-based well-being programmes are a promising innovation. Other healthcare systems may draw on VHA's experience while tailoring format and content to the needs of their patient populations.

PATIENT OR PUBLIC CONTRIBUTION

Veterans were involved as evaluation participants. A Veteran consultant, who is a coauthor on this paper, was engaged through the conceptualization of the evaluation, development of data collection materials (interview guide) and writing.

Social Determinants of Health: Considerations for Care of Older Veterans

Social determinants of health (SDOH), the environments and circumstances in which people are born, grow, live, work and age, are potent drivers of health, health disparities, and health outcomes over the lifespan. Military service affords unique experiences, exposures, and social and health vulnerabilities which impact the life course and may alter health equity and health outcomes for older veterans. Identifying and addressing SDOH, inclusive of the military experience, allows person-centered, more equitable care to this vulnerable population. Nurses and other health professionals should be familiar with how to identify and address health-related social needs and implement interdiciplinary, team-based approaches to connect patients with resources and benefits specifically available to veterans.

Accelerating Implementation of Virtual Care in an Integrated Health Care System: Future Research and Operations Priorities

BACKGROUND

Virtual care is critical to Veterans Health Administration (VHA) efforts to expand veterans' access to care. Health care policies such as the Veterans Access, Choice, and Accountability (CHOICE) Act and the Maintaining Internal Systems and Strengthening Integrated Outside Networks (MISSION) Act impact how the VHA provides care. Research on ways to refine virtual care delivery models to meet the needs of veterans, clinicians, and VHA stakeholders is needed.

OBJECTIVE

Given the importance of virtual approaches for increasing access to high-quality VHA care, in December 2019, we convened a Think Tank, Accelerating Implementation of Virtual Care in VHA Practice, to consider challenges to virtual care research and practice across the VHA, discuss novel approaches to using and evaluating virtual care, assess perspectives on virtual care, and develop priorities to enhance virtual care in the VHA.

METHODS

We used a participatory approach to develop potential priorities for virtual care research and activities at the VHA. We refined these priorities through force-ranked prioritization and group discussion, and developed solutions for selected priorities.

RESULTS

Think Tank attendees (n = 18) consisted of VHA stakeholders, including operations partners (e.g., Office of Rural Health, Office of Nursing Services, Health Services Research and Development), clinicians (e.g., physicians, nurses, psychologists, physician assistants), and health services researchers. We identified an initial list of fifteen potential priorities and narrowed these down to four. The four priorities were (1) scaling evidence-based practices, (2) centralizing virtual care, (3) creating high-value care within the VHA with virtual care, and (4) identifying appropriate patients for virtual care.

CONCLUSION

Our Think Tank took an important step in setting a partnered research agenda to optimize the use of virtual care within the VHA. We brought together research and operations stakeholders and identified possibilities, partnerships, and potential solutions for virtual care.

Household and area-level social determinants of multimorbidity: a systematic review

BACKGROUND

No clear synthesis of evidence examining household and area-level social determinants of multimorbidity exists. This study aimed to systematically review the existing literature on associations between household and area-level social determinants of health (SDoH) and multimorbidity prevalence or incidence in the general population.

METHODS

Six databases (MedLine, EMBASE, PsychINFO, Web of Science, CINAHL Plus and Scopus) were searched. The search was limited to peer-reviewed studies conducted in high-income countries and published in English between 2010 and 2019. A second reviewer screened all titles with abstracts and a subset of full texts. Study quality was assessed and protocol pre-registered (CRD42019135281).

RESULTS

41 studies spanning North America, Europe and Australasia were included. Household income and area-level deprivation were the most explored with fairly consistent findings. The odds of multimorbidity were up to 4.4 times higher for participants with the lowest level of income compared with the highest level. Those living in the most deprived areas had the highest prevalence or incidence of multimorbidity (pooled OR 1.42, 95% CI 1.41 to 1.42). Associations between deprivation and multimorbidity differed by age and multimorbidity type. Findings from the few studies investigating household tenure, household composition and area-level rurality were mixed and contradictory; homeownership and rurality were associated with increased and decreased multimorbidity, while living alone was found to be associated with a higher risk of multimorbidity and not associated.

CONCLUSION

Improving our understanding of broader social determinants of multimorbidity-particularly at the household level-could help inform strategies to tackle multimorbidity.

Demographic Correlates of Veterans' Adverse Social Determinants of Health

INTRODUCTION

Identifying patient populations most affected by adverse social determinants of health can direct epidemiologic investigation, guide development of tailored interventions, and improve clinical care and outcomes. This study explores how demographic characteristics are associated with specific types-and cumulative burden-of adverse social determinants of health among Veterans seeking Veterans Health Administration health care.

METHODS

Data included electronic health records for 293,872 patients of Veterans Health Administration facilities in one region of the country between October 1, 2015 and September 30, 2016. A series of multiple logistic regressions conducted between August and December 2019 examined how demographic variables are associated with 7 adverse social determinants of health. A negative binomial regression examined the association between demographic characteristics and cumulative burden of social determinants of health.

RESULTS

Demographic characteristics were associated with increased odds of each type of adverse social determinant of health: minority race, unmarried status, and Veterans' service connected disability status. Conversely, living in a rural area and being aged >40 years were associated with decreased odds of most of the adverse social determinants of health studied here. Hispanic ethnicity and female sex were inconsistently associated with increased odds of some adverse social determinants of health and decreased odds of others. These results are mirrored in the analysis of predictors of cumulative burden of adverse social determinants of health.

CONCLUSIONS

There is increasing and ongoing interest in ways to identify and respond to patients' experiences of or exposures to adverse social determinants of health. Demographic characteristics may signal the need to assess for adverse social determinants of health. Analyses exploring latent factors among these social determinants (e.g., poverty) may inform strategies to identify patients experiencing adverse social determinants of health and provide responsive interventions.

Veterans With Cancer: Providing Care in the Community

Cancer is more prevalent in the military veteran population than in the general population and is often associated with radiation and chemical exposures encountered while in service. Veterans with cancer may have complex comorbidities, including mental health conditions and social challenges, that can interfere with successful cancer treatment. As more veterans receive their cancer care in the community outside the Veterans Health Administration (VHA), oncology nurses must be aware of these issues and provide appropriate interventions to increase the likelihood that positive cancer treatment outcomes are realized for these patients.

Veterans' assignment to single-site versus scattered-site permanent supportive housing

To address homelessness among Veterans, a growing proportion of permanent supportive housing units supported by the U.S. Departments of Housing and Urban Development and Veterans Affairs Supportive Housing (HUD-VASH) program are allocated to programs where multiple Veterans with a history of homelessness live in a particular building, referred to as single-site housing. This mixed-methods study-including administrative data from Veterans who moved into HUD-VASH housing and qualitative data from focus groups with services providers at 10 single-site programs-describes the characteristics and needs of Veterans who moved into single-site HUD-VASH programs, the rationale for developing single-site HUD-VASH programs, and the services provided in single-site programs that are responsive to Veterans' needs. Based on quantitative analyses, Veterans who were older and had chronic medical and mental health conditions and sought related care were at increased odds of receiving single-site housing. Qualitatively, we found that HUD-VASH programs developed single-site programs for two reasons: to ensure that the most vulnerable Veterans remained housed through the provision of supportive services and to increase housing options for hard-to-house Veterans, including those who require more support because of medical, mental health, or substance use disorders; physical disabilities; or lack of ability to live independently for other reasons. Due to the high needs of Veterans served by single-site programs, development of these programs should consider both space and staffing needs. Future research should assess the relationship between assignment to housing type and health and housing outcomes for participants as well as service enhancements to address Veterans' needs.
