Cardiovascular Risk Screening among Women Veterans: Identifying Provider and Patient Barriers and Facilitators to Develop a Clinical Toolkit

Challenges to Cardiovascular Health Among Female U.S. Veterans and Future Implications: A Scoping Review

INTRODUCTION

Cardiovascular disease (CVD) is the leading cause of death for women in the United States, and U.S. female Veterans have higher rates of CVD compared to civilian women. With an increasing number of women joining the military, the number of female Veterans is expected to rise; therefore, providing appropriate cardiovascular care must be a top priority for the DoD and the Veterans Health Administration (VHA). This scoping review will answer the question: "Among U.S. female Veterans, what are the challenges faced in cardiovascular health, and what are potential future implications and interventions?" We designed this scoping review to identify common themes and gaps in the literature, guide further investigations, and contribute to developing targeted interventions and policies to enhance cardiovascular outcomes among female Veterans.

MATERIALS AND METHODS

On May 1, 2024, a modified PRISMA-ScR search was performed using the following online databases: PubMed, CINAHL, and OVID. The inclusion criteria included U.S. female Veterans, CVD, and data collected from VHA database sources. Results from any literature source published in the past 10 years and written in English were considered. The search identified 107 studies. Two independent reviewers screened titles and abstracts and then performed full-text reviews.

RESULTS

We identified 34 studies assessing challenges to cardiovascular care among female Veterans in areas of racial/ethnic and gender-specific disparities regarding the prevalence of nontraditional CVD risk factors, access to health care services, awareness and knowledge of CVD risk factors, and willingness to receive cardiovascular care. The review also identified potential areas for improvement initiatives in education, peer support, and future research.

CONCLUSIONS

This review highlighted 3 main challenges female Veterans face in accessing CVD care from the VHA: perceived barriers, unique risk factors, and gender/racial disparities. It emphasized the need for improved CVD research, screening, education, and social support for female Veterans. The authors propose two main strategies to address these challenges: (1) pre-transition education from the DoD and (2) enhanced CVD training in the VHA. Cardiovascular disease risk factor recognition and prevention education should occur in military settings, allowing medical providers in DoD clinics to engage female service members in discussions and screenings before transitioning to VHA care. The VHA should educate providers on the barriers female Veterans face, the identification of nontraditional risk factors, and existing health care disparities. Additionally, it should continue to support successful initiatives focused on improving CVD care for female Veterans, such as the Women's Health Research Network, the Quality Enhancement Research Initiative, and the Enhancing Mental and Physical Health of Women through Engagement and Retention program.

An Evidence Map of the Women Veterans' Health Literature, 2016 to 2023: A Systematic Review

Importance

Women veterans are the fastest-growing veteran subpopulation in the US. Women veterans often experience military service-related health issues in addition to conditions common to all women. Because women veterans are more likely to receive care in the civilian setting than through the Department of Veterans Affairs (VA), all women's health clinicians should be equipped to provide patient-centered care for women veterans. The health care of women veterans requires evidence-based care informed by population-specific scientific literature. An updated evidence map evaluating women veteran-focused health literature is needed.

Objective

To map the scope and breadth of women veterans' health literature published from 2016 to 2023.

Evidence Review

In this systematic review, MEDLINE, Embase, and CINAHL Complete were searched for eligible articles published from 2016 to 2023. Articles reporting about US women veterans' health outcomes or on the experience of providing care to women veterans were included. Included articles were required to report patient-level outcomes that included either data for only women veterans or reported results separately for women veterans. Articles were grouped by primary focus area based on categories previously established by the VA Women's Health research agendas and prior evidence maps.

Findings

The volume of women veterans' health literature published between 2016 and 2023 of 932 articles was double that of the prior 8 years. The largest portion of this literature was focused on chronic medical conditions (137 articles [15%]), general mental health (203 articles [22%]), and interpersonal violence (121 articles 3[13%]). Areas of greatest growth included reproductive health (physical and mental), pain, suicide, and nonsuicidal self-injury. Additionally, emerging areas of inquiry were found, including military-related toxic exposures and harassment within the health care setting.

Conclusions and Relevance

In this systematic review of literature focused on the health of women veterans, the volume of literature was found to have doubled and expanded in important areas that aligned with VA research priorities. However, despite the growth in research related to women veterans, several important research gaps remain within this field of study. Research addressing health issues pertinent to a growing and aging women veterans' population will require rigorous research and program evaluations.

Tailoring Chronic Disease Interventions to Meet Specific Needs of Women: A Case Example of a Hypertension Program

Background

Women have a unique risk profile for cardiovascular disease (CVD) due to underlying sociocultural and biological determinants. Current CVD prevention and treatment interventions, however, largely remain agnostic to the influences of an individual's sex assigned at birth or gender identity. This study describes a process for tailoring existing evidence-based interventions to the biological and sociocultural determinants of health for women.

Methods

This study adapted the Team-supported, Electronic Health Record (EHR)-leveraged, Active Management (TEAM) CVD preventative care intervention designed for telehealth-based remote hypertension (HTN) care in rural Veterans. Tailoring choices were informed by a 12-month process including a focused literature review, qualitative interviews with women's health experts, and feedback from providers and women Veterans on existing intervention materials.

Results

Literature review and qualitative interview findings informed the modification of patient- and provider-facing TEAM materials. Patient-facing material modifications included the addition of information relevant to sex-specific CVD risk factors, addressing gender-related barriers to CVD risk reduction, and including diverse visual representation and inclusive language. Provider-facing materials were modified through a new EHR template to comprehensively address sex-specific CVD risk factors. These changes resulted in individualized care plans to better address gaps in HTN management among women.

Conclusion

Tailoring existing evidence-based interventions is an achievable and practical strategy to incorporate the sociocultural and biological determinants of CVD health specific to women. This approach could be used to adapt other programs and interventions designed to address health conditions that occur among both men and women but which are sensitive to important biological and sociocultural determinants. These findings highlight the broad discourse on sex- and gender-sensitive health care interventions and advocate for the integration of these interventions into routine clinical practice.

Understanding Pregnancy-Related Cardiovascular Disease Risk Communication and Management Among Women Veterans

Background: Women veterans who experience certain conditions during pregnancy, such as gestational hypertension, pre-eclampsia, and gestational diabetes, are at increased risk of developing cardiovascular disease (CVD) later in life. Many women are unaware of this risk. Furthermore, women often face financial, socioeconomic, or physical challenges when trying to make healthy behavior modifications to reduce CVD risk. Objective: To examine Veterans' pregnancy-related cardiovascular (CV) risk conditions, risk identification, and risk communication with primary care providers. Research Design: Telephone/video interviews were conducted with female Veterans who had experienced at least one sex-specific CV risk condition during pregnancy. Interviews were recorded, transcribed, and analyzed using content analysis techniques. Major themes and representative quotes were derived. Results: Twenty-eight women Veterans participated in the study, conducted between October and December 2023. A majority of participants were racial/ethnic minorities, and the average age was 38. Four themes arose: (1) Veterans Affairs (VA) medical records may contain limited information regarding CV risk factors experienced during pregnancy; (2) strong relationships between Veterans and their VA primary care providers can facilitate management of CV risk factors following pregnancy; (3) some Veterans receive vague and/or conflicting recommendations for CV risk reduction following pregnancy; and (4) social determinants of health may play a key role in Veterans' ability to follow recommended CV risk reduction behaviors. Conclusions: Women Veterans with pregnancy-related CV risk conditions may not know that they are at increased risk of developing future CVD conditions, often because VA providers receive limited records from outside providers. Those who are aware often receive conflicting or vague recommendations to address these risk factors. When trying to follow CV health recommendations, many women have difficulty due to lack of finances, childcare, or safe areas. Future interventions should be aimed at improving access to medical records between outside and VA providers, patient education, and access to heart-healthy resources.

Implementation of a cardiovascular toolkit in primary care increased women Veterans' engagement in behavior change programs: results from a non-randomized stepped wedge trial

Background

Cardiovascular (CV) disease is the leading cause of death among U.S. women, yet women have a limited understanding of their CV-related morbidity and mortality risks. Provider-, system-, and patient-level barriers point to a need for multi-level evidence-based strategies to facilitate CV risk reduction. Guided by the Replicating Effective Programs framework and complexity theory, we implemented a CV Toolkit in primary care clinics for women Veterans. The objective was to evaluate the effect of implementation of CV toolkit on participation in behavior change programs that target CV risk reduction.

Methods

In partnership with the Veterans Health Administration (VA) Office of Women's Health and National Center for Health Promotion and Disease Prevention, we developed and implemented a CV Toolkit at five geographically diverse VA sites between March 2017-March 2020. Using a non-randomized stepped wedge design, we evaluated the effect of the implementation of toolkit on participation in the VA MOVE! weight management program, and on participation in health promotion and disease prevention (HPDP) programs (coaching, facilitated groups, etc.) and/or complementary integrative health (CIH) programs (yoga, meditation, etc.). We utilized a three-level (patient, site, time) non-linear fixed effect model with stratification by age (65 and older versus younger). Patient participation, utilization, and demographics were extracted from VA administrative data for all women with at least one primary care visit at a participating site from December 2016-March 2020 (n = 6009).

Results

Women were on average 45 years old; 38% were white, 31% Black, 17% Hispanic; and over a third had CV risk factors and/or mental health diagnoses. For women 65 years and older (n = 540), active toolkit implementation resulted in increased odds of MOVE! participation (OR = 1.09; 95% CI:1.030-1.152) compared to when the toolkit was not active either within or between sites. Women younger than 65 (n = 5469) had increased odds of using HPDP/CIH programs during active toolkit implementation (OR = 1.01; 95% CI:1.002-1.022).

Conclusions

Active implementation of the CV Toolkit intervention was significantly associated with increasing participation in behavior change programs. Variation in program participation by age suggests that the diversity of behavior change programs available to women Veterans may facilitate participation across the lifespan.

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.

Trends in Cardiovascular Disease Mortality in US Women Veterans vs Civilians

Importance

Cardiovascular disease (CVD) remains the leading cause of death in the US. Women veterans have higher rates of CVD compared with civilian US women; however, analyses of recent trends in mortality from cardiac disease for women veterans are lacking.

Objective

To investigate trends in cardiac disease mortality among women veterans over approximately the past 2 decades and compare rates with those for civilian women.

Design, Setting, and Participants

In this retrospective longitudinal cohort study, US Veterans Health Administration (VHA) electronic health record data, linked with the National Death Index, were analyzed for CVD trends and rates of cardiac disease mortality among women veterans (aged 18 years or older) with VHA health care encounters from January 1, 2000, to December 31, 2017. These data were compared with a national cohort of civilian women (aged 15 years or older) in the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database, which provides cause-of-death data using death certificates for all US residents. The data analysis was performed between March 10, 2021, and November 28, 2022.

Exposure

Cardiac disease mortality among women veterans and civilian women.

Main Outcomes and Measures

Cardiac disease mortality was based on International Classification of Diseases, Tenth Revision diagnostic codes (I00-I09, I11, I13, and I20-I51 as defined by CDC WONDER). For women veterans and civilian women, crude and age-adjusted cardiac disease mortality rates (per 100 000 life-years) and 95% CIs were calculated, with the 2000 US general population as the reference for age-adjusted rates.

Results

From 2000 to 2017, 817 912 women veterans engaged with VHA health care (mean [SD] age, 45.7 [17.1] years), and 19 022 cardiac disease deaths were identified (22.4% of total deaths). The crude and age-adjusted cardiac disease mortality rates, respectively, per 100 000 life-years were 200.2 (95% CI, 181.0-221.0) and 197.6 (95% CI, 175.2-222.0) in 2000 and 196.0 (95% CI, 186.1-206.4) and 208.1 (95% CI, 196.4-220.4) in 2017, reflecting stable crude rates and a 5.3% increase in age-adjusted rates. For civilian women, the crude and age-adjusted rates decreased over time from 320.7 (95% CI, 319.7-321.8) and 268.1 (95% CI, 267.3-269.0) in 2000 to 220.9 (95% CI, 220.1-221.7) and 164.7 (95% CI, 164.1-165.3) in 2017.

Conclusions and Relevance

In this cohort study comparing women veterans and civilian women, cardiac disease mortality rates for women veterans did not exhibit the improvements seen for civilian women during the nearly 2-decade study period. Further research and actionable clinical interventions are warranted to improve cardiovascular care for women veterans, who represent the fastest growing group of patients within the VHA health care system.

Ask and Ask Again: Repeated Screening for Smoking Increases Likelihood of Prescription for Cessation Treatment Among Women Veterans

BACKGROUND

Preventive screening at the point of care can increase desired clinical outcomes. However, the impact of repeated screening for tobacco use on receiving smoking cessation treatment among women Veteran population has not been documented.

OBJECTIVE

To examine screening for tobacco use using clinical reminders and the association between the number of screenings and prescription for cessation treatment.

DESIGN

A retrospective analysis using data from a 5-year implementation trial for cardiovascular risk identification conducted between December 2016 and March 2020.

SUBJECTS

Women patients who had at least one primary care visit with a women's health provider during the study period at five primary care clinics in the Veterans Affairs (VA) Healthcare System.

MEASURES

The outcome is prescription of pharmacotherapy or referral to behavioral counseling for smoking cessation on or after the screening date. The exposure is the number of screenings for tobacco use from the trial and the annual VA national clinical reminders during the study period.

RESULTS

Of 6009 eligible patients, 5788 (96.3%) were screened at least once for tobacco use over five calendar years, and 2784 of those screened (48.1%) were reported as current and former smokers. Among current and former smokers, 709 (25.5%) received a prescription and/or referral for smoking cessation. In the adjusted model, the average predicted probability of prescription and/or referral for smoking cessation was 13.7% among current and former smokers screened once over 5 years, 18.6% among screened twice, 26.5% among screened thrice, 32.9% among screened four times, and 41.7% among screened five or six times.

CONCLUSIONS

Repeated screening was associated with higher predicted probabilities of being prescribed smoking cessation treatment.

Implementing clinical decision support for reducing women Veterans' cardiovascular risk in VA: A mixed-method, longitudinal study of context, adaptation, and uptake

Evaluations of clinical decision support (CDS) implementation often struggle to measure and explain heterogeneity in uptake over time and across settings, and to account for the impact of context and adaptation on implementation success. In 2017-2020, the EMPOWER QUERI implemented a cardiovascular toolkit using a computerized template aimed at reducing women Veterans' cardiovascular risk across five Veterans Healthcare Administration (VA) sites, using an enhanced Replicating Effective Programs (REP) implementation approach. In this study, we used longitudinal joint displays of qualitative and quantitative findings to explore (1) how contextual factors emerged across sites, (2) how the template and implementation strategies were adapted in response to contextual factors, and (3) how contextual factors and adaptations coincided with template uptake across sites and over time. We identified site structure, staffing changes, relational authority of champions, and external leadership as important contextual factors. These factors gave rise to adaptations such as splitting the template into multiple parts, pairing the template with a computerized reminder, conducting academic detailing, creating cheat sheets, and using small-scale pilot testing. All five sites exhibited variability in utilization over the months of implementation, though later sites exhibited higher template utilization immediately post-launch, possibly reflecting a "preloading" of adaptations from previous sites. These findings underscore the importance of adaptive approaches to implementation, with intentional shifts in intervention and strategy to meet the needs of individual sites, as well as the value of integrating mixed-method data sources in conducting longitudinal evaluation of implementation efforts.
