Associations between Posttraumatic Stress Disorder and Diabetes in Vietnam-Era Women Veterans in the HealthViEWS Study

Background: Posttraumatic stress disorder (PTSD) is associated with incident diabetes. However, past studies have often included predominantly male samples, despite important sex and gender differences in diabetes. To address this limitation, this study examined the association between PTSD and diabetes in older Veteran women, a population with a high burden of PTSD. Materials and Methods: Data were collected from 4,105 women (Mage = 67.4 years), participating in the Health of Vietnam-Era Veteran Women's Study (HealthViEWS; Department of Veterans Affairs Cooperative Studies Program #579). Participants completed self-report measures of demographics, health conditions, and health behaviors. Information on military service was obtained through service records. A structured clinical interview was conducted by telephone to assess current and lifetime PTSD and other mental health disorders. Weighted descriptive and logistic regression analyses were used to examine associations between PTSD and diabetes. Results: The prevalence of diabetes was 28.4% among women with current full PTSD compared to 23.4%, 17.6%, and 17.5% for current subthreshold, remitted, and no PTSD. In unadjusted analyses, women with current full and subthreshold PTSD were 1.87 [1.49; 2.33] and 1.44 [1.11; 1.85] times more likely to have diabetes compared to women with no PTSD. Remitted PTSD was not associated with increased odds of diabetes. Effects were attenuated but remained significant after adjustment for relevant covariates. Conclusions: Vietnam-era women with current PTSD, including subthreshold symptoms, had a greater likelihood of diabetes compared to women without PTSD. These findings suggest that women with PTSD may benefit from increased diabetes prevention efforts.

Physical and emotional consequences of excess weight as experienced by individuals with spinal cord injuries

CONTEXT/OBJECTIVE

Excess weight has the potential to carry a substantial physical and emotional burden. A better understanding of perceived consequences of excess weight may facilitate the development of patient-centered programs and interventions to promote weight management efforts in persons with spinal cord injury (SCI). The study objective was to describe consequences of excess weight from the personal perspectives of individuals with SCI.

DESIGN

Descriptive qualitative design using in-depth semi-structured interviews and thematic analysis.

SETTING

Veterans Health Administration (VHA) SCI System of Care.

PARTICIPANTS

Individuals with SCI (n-33).

OUTCOME MEASURES

Key themes from thematic analysis.

RESULTS

Participants were male (61%), ranged from 29 to 84 years of age, and about half had tetraplegia (55%). Five themes were identified that demonstrate negative consequences of excess weight experienced by individuals with SCI, including: (1) physical health conditions (including chronic conditions and SCI secondary conditions), (2) physical symptoms (such as pain, discomfort, and fatigue), (3) movement challenges, (4) appearance-related concerns, and (5) emotional impacts.

CONCLUSIONS

Carrying excess weight is concerning to individuals with SCI and in terms of consequences such onset or exacerbation of chronic conditions, SCI secondary conditions, physical symptoms, e.g. pain, movement impairment (including hampered mobility, difficult transfers and self-care), image/appearance concerns (e.g. body image, clothing misfit), and negative emotions (e.g. unhappy, sad, depressed). Our findings may inform SCI healthcare providers about the consequences of excess weight as experienced by individuals with SCI, highlighting what matters most to persons with SCI and guiding a patient-centered approach to weight management in this population.

Behavioral weight management use in the Veterans Health Administration: Sociodemographic and health correlates

INTRODUCTION

Over 40 % of United States Veterans Health Administration (VHA) primary care patients have obesity. Few patients use VHA's flagship weight management program, MOVE! and there is little information on other behavioral weight management program use.

METHODS

The national United States cohort included over 1.5 million primary care patients with obesity, age 18-79, based on VHA administrative data. Gender stratified multivariable logistic regression identified correlates of weight management use in the year after a patient's first primary care appointment (alpha of 0.05). Weight management use was defined as MOVE! or nutrition clinic visits.

RESULTS

The cohort included 121,235 women and 1,521,547 men with 13 % and 7 % using weight management, respectively. Point estimates for specific correlates of use were similar between women and men, and across programs. Black patients were more likely to use weight management than White patients. Several physical and mental health diagnoses were also associated with increased use, such as sleep apnea and eating disorders. Age and distance from VHA were negatively associated with weight management use.

CONCLUSIONS

When assessing multiple types of weight management visits, weight management care in VHA appears to be used more often by some populations at higher risk for obesity. Other groups may need additional outreach, such as those living far from VHA. Future work should focus on outreach and prevention efforts to increase overall use rates. This work could also examine the benefits of tailoring care for populations in greatest need.

Nutrition and eating beliefs and behaviors among individuals with spinal cord injuries and disorders: Healthy or misconceived?

PURPOSE/OBJECTIVE

Nutrition knowledge, beliefs, and behaviors have important implications for managing and preventing chronic and injury-related secondary conditions in persons with spinal cord injuries and disorders (SCI/D). Yet, the unique dietary and nutritional needs and recommendations specific to individuals with SCI/D and their eating beliefs and behaviors have been understudied. Aim is to describe nutrition and eating beliefs and behaviors from the perspectives of individuals with SCI/D.

RESEARCH METHOD/DESIGN

Descriptive qualitative design using in-depth semistructured interviews with a national sample of veterans with SCI/D (n = 33). Audio-recorded and transcribed verbatim transcripts were coded and analyzed using thematic analysis.

RESULTS

Participants were male (61%), aged 29-84 years, and 55% had tetraplegia. Five key themes were identified: extreme fasting/caloric restriction, perceived healthy eating behaviors, perceived unhealthy eating behaviors, modified eating behaviors due to SCI/D-related symptoms, and food/preparation choices based on abilities/independence and access.

CONCLUSIONS/IMPLICATIONS

Nutrition among veterans with SCI/D may be impacted by many factors, such as nutrition knowledge and beliefs/behaviors about "healthy" and "unhealthy" nutrition, fasting, caloric restriction, imbalanced intake of macro- and micronutrients, overconsumption relative to energy needs, injury-related secondary complications, postinjury body composition and function changes, impairments related to satiety and hunger signals, and difficulty in obtaining and preparing food. Study findings provide many areas that would benefit from intervention. Findings can be used to inform ideal nutrition and healthy eating beliefs and behaviors which are important because nutritional inadequacies can lead to diet-related diseases, may exacerbate SCI secondary conditions, and lead to poor overall health.

Why may patients with spinal cord injury be overlooked for obesity screening in the Veterans Health Administration? Qualitative research of the perspectives of patients and healthcare providers

PURPOSE

We sought to describe factors influencing reduced rates of obesity screening for patients with spinal cord injury (SCI) in the United States Veterans Health Administration (VA) and to foster potential solutions.

MATERIALS AND METHODS

Semi-structured interviews with healthcare providers and patients with SCI who were recruited nationally from diverse VAs. We performed rapid qualitative analysis using content analysis of interview data.

RESULTS

There were 36 providers and 37 patients. We identified provider, patient, and system level barriers to obesity screening for individuals with SCI. Overarching barriers involved provider and patient perceptions that obesity screening is a low priority compared to other health conditions, and body mass index is of low utility. Other obesity screening barriers were related to measuring weight (i.e., insufficient equipment, unknown wheelchair weight, staffing shortages, measurement errors, reduced access to annual screening, insufficient time, patient preference not to be weighed) and measuring height (i.e., insufficient guidance and equipment to this population, measurement errors).

CONCLUSIONS

Barriers to obesity screenings exist for patients with SCI receiving care in VA. Healthcare provider and patient interviews suggest possible solutions, including standardizing height and weight measurement processes, ensuring equipment availability in clinics, clarifying guidelines, and offering support to providers and patients.IMPLICATIONS FOR REHABILITATIONIndividuals with spinal cord injury (SCI) have higher rates of obesity, but are often overlooked for annual obesity screening, even in clinic settings designed to care for individuals with SCI.Results may help tailor guidelines/education for healthcare and rehabilitation providers offering them guidance for improving obesity screening for individuals with SCI by standardizing weight and height measurement and documentation. To facilitate this, findings highlight the need for resources, such as ensuring clinics have necessary equipment, and increasing patient access to support and equipment.Improving the provision of obesity screening for individuals with SCI is necessary to improve health outcomes and patient satisfaction with care.

The EMBER trial for weight management engagement: A hybrid type 1 randomized controlled trial protocol

BACKGROUND

Almost 40% of Veterans Health Administration (VHA) users have obesity. VHA's national weight management program is associated with weight loss and improved health. However, while 94% of eligible VHA users are offered weight management programs, <8% use them. We developed EMBER - a novel, Motivational Interviewing-based, self-help tool - with the goal of Enhancing Motivation for Better Engagement and Reach for weight management. EMBER is not a weight management program; instead it engages people in existing programs by informing and guiding choices about weight management.

METHODS

The EMBER Trial is a randomized hybrid type 1 effectiveness implementation trial. Participants are Palo Alto or Houston VA Health Care System users with obesity who have not used a VHA weight management program in the past two years (target N = 470). Participants are randomly assigned to EMBER or an information-only control condition, after which they receive materials on paper or digitally, per their preference. The trial's primary goal is to determine whether participants randomized to EMBER are more likely to have any weight management engagement at two-month follow-up compared to those in the control condition. Secondary outcomes include 6-month retention in weight management, weight management behaviors, weight loss, quality of life, and implementation outcomes (e.g., reach, appropriateness).

CONCLUSION

EMBER is the first self-directed, Motivational Interviewing-based intervention designed to increase weight management program engagement. The study takes a low-touch, population health approach that could be modified for other programs if effective. The Hybrid Type 1 design will ensure results can be scaled and sustained.

RE-AIM applied to a primary care workforce training for rural providers and nurses: the Department of Veterans Affairs' Rural Women's Health Mini-Residency

Introduction

Application of the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework to evaluate workforce education and training programs targeting clinical health care staff has received relatively little attention. This paper aims to contribute to this area with RE-AIM findings from a women's health-focused workforce training program implemented by the U.S. Department of Veterans Affairs (VA). Over the past two decades, the rapid expansion of the women Veteran population in VA has necessitated a quick response to meet clinical demand. To address this health care need, the VA Offices of Rural Health (ORH) and Women's Health (OWH) partnered to deploy a primary care workforce development initiative for Rural Providers and Nurses-the Rural Women's Health Mini-Residency (Rural WH-MR)-to train VA clinicians in rural locations in skills for the care of women Veterans. Here we assess the applicability of RE-AIM as an evaluation framework in this context.

Methods

We evaluated the Rural WH-MR, relying on a primarily quantitative approach, rooted in RE-AIM. It included longitudinal and cross-sectional measurements from multiple quantitative and qualitative data sources to develop selected metrics. Data collection instruments consisted of pre-, post-, and follow-up training surveys, course evaluations, existing VA databases, and implementation reports. We developed metrics for and assessed each RE-AIM component by combining data from multiple instruments and then triangulating findings.

Results

Results from the Rural WH-MR program for fiscal years 2018-2020 indicate that RE-AIM provides an instructive evaluation framework for a rural workforce training program, particularly in eliciting clarity between measures of Reach vs. Adoption and focusing attention on both provider- and patient-level outcomes.

Discussion

We describe evaluation metric development and barriers to and facilitators of utilizing RE-AIM as an evaluation framework for a provider- and nurse-facing intervention such as this workforce training program. We also reflect upon RE-AIM benefits for highlighting process and outcomes indicators of a training program's success and lessons learned for evaluating rural workforce development innovations. Several of our observations have implications for training and evaluation approaches in rural areas with more limited access to health care services.

Interaction between increasing body mass index and spinal cord injury to the probability of developing a diagnosis of nonalcoholic fatty liver disease

Background

The prevalence of obesity and comorbidities is high in the population with spinal cord injury (SCI). We sought to determine the effect of SCI on the functional form of the relationship between body mass index (BMI) and risk of developing nonalcoholic fatty liver disease (NAFLD), and assess whether SCI-specific mapping of BMI to risk of developing NAFLD is needed.

Methods

Longitudinal cohort study comparing Veterans Health Administration patients with a diagnosis of SCI to a 1:2 matched control group without SCI. The relationship between BMI and development of NAFLD at any time was assessed with propensity score matched Cox regression models; NAFLD development at 10-year with a propensity score matched logistic model. The positive predictive value of developing NAFLD at 10 years was calculated for BMI 19-45 kg/m2.

Results

14,890 individuals with SCI met study inclusion criteria, and 29,780 Non-SCI individuals in matched control group. Overall, 9.2% in SCI group and 7.3% in Non-SCI group developed NAFLD during the study period. A logistic model assessing the relationship between BMI and the probability of developing a diagnosis of NAFLD demonstrated that the probability of developing disease increased as BMI increased in both cohorts. The probability was significantly higher in the SCI cohort at each BMI threshold (p < 0.01), and increased at a higher rate compared with the Non-SCI cohort as BMI increased 19-45 kg/m2. Positive predictive value for developing a diagnosis of NAFLD was higher in the SCI group for any given BMI threshold from 19 kg/m2 to BMI 45 kg/m2.

Conclusions

The probability of developing NAFLD is greater in individuals with SCI than without SCI, at every BMI level 19 kg/m2 to 45 kg/m2. Individuals with SCI may warrant a higher level of suspicion and closer screening for NAFLD. The association of SCI and BMI is not linear.

Common Sense Models of Obesity: a Qualitative Investigation of Illness Representations

BACKGROUND

The Common Sense Model provides a framework to understand health beliefs and behaviors. It includes illness representations comprised of five domains (identity, cause, consequences, timeline, and control/cure). While widely used, it is rarely applied to obesity, yet could explain self-management decisions and inform treatments. This study answered the question, what are patients' illness representations of obesity?; and examined the Common Sense Model's utility in the context of obesity.

METHODS

Twenty-four participants with obesity completed semi-structured phone interviews (12 women, 12 men). Directed content analysis of transcripts/notes was used to understand obesity illness representations across the five illness domains. Potential differences by gender and race/ethnicity were assessed.

RESULTS

Participants did not use clinical terms to discuss weight. Participants' experiences across domains were interconnected. Most described interacting life systems as causing weight problems and used negative consequences of obesity to identify it as a health threat. The control/cure of obesity was discussed within every domain. Participants focused on health and appearance consequences (the former most salient to older, the latter most salient to younger adults). Weight-related timelines were generally chronic. Women more often described negative illness representations and episodic causes (e.g., pregnancy). No patterns were identified by race/ethnicity.

CONCLUSIONS

The Common Sense Model is useful in the context of obesity. Obesity illness representations highlighted complex causes and consequences of obesity and its management. To improve weight-related care, researchers and clinicians should focus on these beliefs in relation to preferred labels for obesity, obesity's most salient consequences, and ways of monitoring change.

An exploratory analysis of factors associated with spontaneous preterm birth among pregnant veterans with post-traumatic stress disorder

BACKGROUND

Pregnant veterans with post-traumatic stress disorder (PTSD) are at increased risk for spontaneous preterm birth, yet the underlying reasons are unclear. We examined factors associated with spontaneous preterm birth among pregnant veterans with active PTSD.

METHODS

This was an observational study of births from administrative databases reimbursed by the Veterans Health Association (VA) between 2005 and 2015. Singleton livebirths among veterans with active PTSD within 12 months prior to childbirth were included. The primary outcome was spontaneous preterm birth. Maternal demographics, psychiatric history, and pregnancy complications were evaluated as exposures. Covariates significant on bivariate analysis, as well as age and race/ethnicity as a social construct, were included in multivariable logistic regression to identify factors associated with spontaneous preterm birth. Additional analyses stratified significant covariates by the presence of active concurrent depression and explored interactions between antidepressant use and preeclampsia.

RESULTS

Of 3,242 eligible births to veterans with active PTSD, 249 (7.7%) were spontaneous preterm births. The majority of veterans with active PTSD (79.1%) received some type of mental health treatment, and active concurrent depression was prevalent (61.4%). Preeclampsia/eclampsia (adjusted odds ratio [aOR] 3.30, 95% confidence interval [CI] 1.67-6.54) and ≥6 antidepressant medication dispensations within 12 months prior to childbirth (aOR 1.89, 95% CI 1.29-2.77) were associated with spontaneous preterm birth. No evidence of interaction was seen between antidepressant use and preeclampsia on spontaneous preterm birth (p=0.39). Findings were similar when stratified by active concurrent depression.

CONCLUSION

Among veterans with active PTSD, preeclampsia/eclampsia and ≥6 antidepressant dispensations were associated with spontaneous preterm birth. While the results do not imply that people should discontinue needed antidepressants during pregnancy in veterans with PTSD, research into these factors might inform preterm birth prevention strategies for this high-risk population.

The impact of the COVID-19 pandemic on individuals living with spinal cord injury: A qualitative study

PURPOSE/OBJECTIVE

To explore the impact of the COVID-19 pandemic as experienced and reported by individuals living with a spinal cord injury (SCI).

RESEARCH METHOD/DESIGN

Descriptive qualitative design using in-depth semistructured interviews with individuals with SCI (n = 33) followed by thematic analysis.

RESULTS

Three main themes described impacts of the COVID-19 pandemic. (a) Impact on health care use; subthemes elaborated that this was attributable to in-person health care facility restrictions or individual decisions to delay care. Individuals with SCI experienced lapses in primary and SCI-specialty care, rehabilitation/therapy services, and home care, but some made use of telehealth services. (b) Impact on weight and/or weight management lifestyle behaviors; subthemes discussed that engagement in physical activity declined because of fitness center closures, recreational activity cancellations, and safety precautions limiting community-based and outdoor activities. The pandemic disrupted participants' independence in purchasing and making preferred food selections which impacted healthy eating. Participants ate due to boredom, at nonmealtimes, and consumed unhealthy foods during the pandemic. (c) Impact on psychosocial factors; included subthemes noting reduced social interactions, social participation, and ability to pursue pastimes with family, friends, and groups they belonged to. The pandemic also triggered emotional reactions such as worry, fear, doubt, demotivation, and feelings of social isolation.

CONCLUSIONS

Our findings highlight the magnitude of consequences faced by individuals with SCI when restrictions to health care, healthy lifestyle endeavors, and social participation occurred during the COVID-19 pandemic. Findings may inform SCI health care providers on what is needed in response to future public health or natural disaster crises. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Gynecologist Supply Deserts Across the VA and in the Community

BACKGROUND

The Veterans Health Administration (VA) refers patients to community providers for specialty services not available on-site. However, community-level specialist shortages may impede access to care.

OBJECTIVE

Compare gynecologist supply in veterans' county of residence versus at their VA site.

DESIGN

We identified women veteran VA patients from fiscal year (FY) 2017 administrative data and assessed availability of a VA gynecologist within 50 miles (hereafter called "local") of veterans' VA homesites (per national VA organizational survey data). For the same cohort, we then assessed community-level gynecologist availability; counties with < 2 gynecologists/10,000 women (per the Area Health Resource File) were "inadequate-supply" counties. We examined the proportion of women veterans with local VA gynecologist availability in counties with inadequate versus adequate gynecologist supply, stratified by individual and VA homesite characteristics. Chi-square tests assessed statistical differences.

PARTICIPANTS

All women veteran FY2017 VA primary care users nationally.

MAIN MEASURES

Availability of a VA gynecologist within 50 miles of a veteran's VA homesite; county-level "inadequate-supply" of gynecologists.

KEY RESULTS

Among 407,482 women, 9% were in gynecologist supply deserts (i.e., lacking local VA gynecologist and living in an inadequate-supply county). The sub-populations with the highest proportions in gynecologist supply deserts were rural residents (24%), those who got their primary care at non-VAMC satellite clinics (13%), those who got their care at a site without a women's clinic (13%), and those with American Indian or Alaska Native (12%), or white (12%) race. Among those in inadequate-supply counties, 59.9% had gynecologists at their local VA; however, 40.1% lacked a local VA gynecologist.

CONCLUSIONS

Most veterans living in inadequate-supply counties had local VA gynecology care, reflecting VA's critical role as a safety net provider. However, for those in gynecologist supply deserts, expanded transportation options, modified staffing models, or tele-gynecology hubs may offer solutions to extend VA gynecology capacity.

Abstract P5-19-05: Successful participation of veterans affairs patients in precision medicine research through passive recruitment efforts

Background Access to clinical trials and other research opportunities is important to discovering new disease treatments and better ways to detect, diagnose, and reduce disease risk. The WISDOM (Women Informed to Screen Depending on Measures of risk) Study is a multi-site, pragmatic trial with web-based participation based at the University of California at San Francisco (UCSF) that aims to move breast cancer screening away from its current one-size-fits-all approach to one that is personalized based on each woman’s individual risk. We sought to evaluate passive recruitment efforts of Veterans Affairs (VA) patients into a precision medicine research program. Methods We created a hub and spoke recruitment model with the San Francisco VA Medical Center (SFVAMC) serving as the central hub of passive recruitment activities and eligible VA facilities that agreed to participate serving as the spoke recruitment sites. Eligible facilities had at least 3,000 women patients, VA clinical genetic services available, a site lead from the VA Women’s Health-Practice-Based Research Network, and mammography on site. Site participation involved permission for the research team to email eligible patients (women age 40-74 without a prior breast cancer diagnosis) about the WISDOM Study. We evaluated the effectiveness of the recruitment by assessing trends in enrollment and monitoring participation of VA patients in the WISDOM Study. The participating sites were determined to be non-engaged in human subjects research. Results Between May 24th, 2021 and June 30th, 2021, we emailed 29,470 eligible VA patients from seven participating VA facilities. Prior to the VA emailing, 2% of the total WISDOM Study population had served or was currently serving in active duty in any of the United States Armed Forces. After the first month of emails, this percentage increased to 50%. The month following VA emailing was one of the highest accruing months for the study with 2175 women registering, doubling the average of the prior three months, with VA participation accounting for over 50% of total enrollment that month. VA enrollment population was racial and ethnically diverse and changed the demographics of study enrollment. Prior to the VA emailing, the WISDOM Study population (n= 32,3278) included women who are 79% non-Hispanic White, 3% Black/African American and 9% Hispanic/Latina. Between the May 24th, 2021 and June 30th, 2021 emailing period, of the 1665 women enrolled, 64% of which were non-Hispanic White, 16% Black/African American and 12% Hispanic/Latina. Most women veterans enrolled in the study were between the ages of 40-50 (45%), which represented a younger population than the general WISDOM Study population (28%, aged 40-50). Both the VA population and general WISDOM Study population had similar levels education: 72% of the VA population had obtained a college graduate degree compared to 76% of the WISDOM study population with a college graduate degree. Conclusions The VA has recently approved email contact as a method for passively recruiting research participants. Our results demonstrate that there is substantial interest among female veterans in the WISDOM Study, and that emailing VA patients was not only feasible but an effective approach to increased study recruitment and diversity of participants. This data provides a unique opportunity for future trials to engage women veterans as precision medicine becomes a growing area of research in the VA and at academic affiliates.

Rates, Variability, and Predictors of Screening for Obesity: Are Individuals with Spinal Cord Injury Being Overlooked?

INTRODUCTION

Individuals with spinal cord injury (SCI) are vulnerable to obesity. Annual obesity screening using body mass index (BMI) is the standard of care mandated by US Veterans Health Administration (VHA) guidelines. Our objective was to determine the rates, variability, and predictors of guideline-concordant annual screening for obesity, given potential challenges of height and weight measurements in individuals with SCI.

METHODS

This is a cross-sectional retrospective study using US national VA databases. We identified all VHA patients with chronic SCI in the fiscal year (FY) 2019, their treating facility and frequency of recorded height and weight. We applied mixed-effects logistic regression models to assess associations between annual BMI screening and patient- and facility-level characteristics.

RESULTS

Of 20,978 individuals with chronic SCI in VHA in FY19, guideline-concordant annual BMI screening was lacking in 37.9%. Accounting for facility-level factors (geographic region, SCI facility type, volume of patients with SCI treated at the facility), a mixed-effects logistic regression model demonstrated that lack of annual obesity screening was significantly associated with older patient age (p < 0.001) and fewer outpatient encounters (p < 0.001) but not other patient-level factors such as sex, race, level of injury, or rurality. The rate of obesity screening among different facilities within VHA varied widely from 11.1% to 75.7%.

CONCLUSION

A large proportion of persons with SCI receiving care in VHA do not receive guideline-concordant annual obesity screening, an especially acute problem in some facilities. Older patients with fewer outpatient encounters are more likely to be missed. To inform the design of interventions to improve identification and documentation of obesity, further study is needed to assess potential barriers to obesity screening in the population with SCI.

Women Veterans' Experiences of Harassment and Perceptions of Veterans Affairs Health Care Settings During a National Anti-Harassment Campaign

PURPOSE

In 2017, Veterans Health Administration (VA) launched a social marketing and training campaign to address harassment of women veterans at VA health care facilities. We assessed women veterans' experiences of harassment, reported perpetrators of harassment, and perceptions of VA in 2017 (before campaign launch) and 2018 (1 year after campaign implementation).

METHODS

We administered surveys to women veterans attending primary care appointments (2017, n = 1,300; 2018, n = 1,711). Participants reported whether they experienced sexual harassment (e.g., catcalls) and gender harassment (e.g., questioning women's veteran status) from patients and/or staff at VA in the past 6 months. They also indicated whether they felt welcome, felt safe, and believed the VA is working to address harassment. We compared variables in 2017 versus 2018 with χ² analyses, adjusting for facility-level clustering.

RESULTS

There were no significant differences in percentages of participants reporting sexual harassment (20% vs. 17%) or gender harassment (11% vs. 11%) in 2017 versus 2018. Men veterans were the most frequently named perpetrators, but participants also reported harassment from staff. Participant beliefs that VA is working to address harassment significantly improved from 2017 to 2018 (52% vs. 57%; p = .05).

CONCLUSIONS

One year after campaign launch, women veterans continued to experience harassment while accessing VA health care services. Findings confirm that ongoing efforts to address and monitor both staff- and patient-perpetrated harassment are essential. Results have implications for future anti-harassment intervention design and implementation and highlight additional opportunities for investigation.

Postpartum Transition of Care: Racial/Ethnic Gaps in Veterans' Re-Engagement in VA Primary Care after Pregnancy

INTRODUCTION

Pregnancy presents an opportunity to engage veterans in health care. Guidelines recommend primary care follow-up in the year postpartum, but loss to follow-up is common, poorly quantified, and especially important for those with gestational diabetes (GDM) and hypertension. Racial maternal inequities are well-documented and might be exacerbated by differential postpartum care. This study explores variation in postpartum re-engagement in U.S. Department of Veteran Affairs health care system (VA) primary care to identify potential racial/ethnic inequities in this care transition.

METHODS

We conducted a complete case analysis of the 2005-2014 national VA birth cohort (n = 18,414), and subcohorts of veterans with GDM (n = 1,253), and hypertensive disorders of pregnancy (HDP; n = 2,052) using VA-reimbursed discharge claims and outpatient data. Outcomes included incidence of any VA primary care visit in the postpartum year; in age-adjusted logistic regression, we explored race/ethnicity as a primary predictor.

RESULTS

In the year after a VA-covered birth, the proportion of veterans with one or more primary care visit was 53.8% overall, and slightly higher in the GDM (56.0%) and HDP (57.4%) subcohorts. In adjusted models, the odds of VA primary care follow-up were significantly lower for Black/African American (odds ratio, 0.87; 95% confidence interval, 0.81-0.93), Asian (odds ratio, 0.76; 95% confidence interval, 0.61-0.95), and Hawaiian/other Pacific Islander (odds ratio, 0.73; 95% confidence interval, 0.55-0.96) veterans, compared with White veterans. Among the subcohorts with GDM or HDP, there were no significant associations between primary care and race/ethnicity.

CONCLUSIONS

One-half of veterans re-engage in VA primary care after childbirth, with significant racial differences in this care transition. Re-engagement for those with the common pregnancy complications of HDP and GDM is only slightly higher, and less than 60%. The potential for innovations like VA maternity care coordinators to address such gaps merits attention.

Rationale and design of the Women's Ischemia Trial to Reduce Events in Nonobstructive CAD (WARRIOR) trial

BACKGROUND

Approximately half of all women with anginal symptoms and/or signs of ischemia and no obstructive coronary artery disease (INOCA) referred for coronary angiography have elevated risk for major adverse cardiac events (MACE), poor quality of life and resource consumption. Yet, guidelines focus on symptom management while clinical practice typically advocates only reassurance. Pilot studies of INOCA subjects suggest benefit with intensive medical therapy (IMT) that includes high-intensity statins and angiotensin converting enzyme inhibitors (ACE-I) or receptor blockers (ARB) to provide the rationale for a randomized pragmatic trial to limit MACE.

METHODS

The Women's IschemiA TRial to Reduce Events In Non-ObstRuctive CAD is a multicenter, prospective, randomized, blinded outcome evaluation (PROBE design) of a pragmatic strategy of IMT vs usual care (UC) in 4,422 symptomatic women with INOCA (NCT03417388) in approximately 70 United States sites. The hypothesis is that IMT will reduce the primary outcome of first occurrence of MACE by 20% vs. UC at ∼2.5 year followup. Secondary outcomes include quality of life, time to return to "duty"/work, healthcare utilization, angina, cardiovascular death and individual primary outcome components over 3 years follow-up. The study utilizes web-based data capture, e-consents, single IRB and centralized pharmacy distribution of strategy medications directly to patients' homes to reduce site and patient burden. A biorepository will collect blood samples to assess potential mechanisms.

CONCLUSIONS

The results of this trial will provide important data necessary to inform guidelines regarding how best to manage this growing and challenging population of women with INOCA.

Promoting learning health system feedback loops: Experience with a VA practice-based research network card study

Background:

We tested the capacity of the 60-site VA Women’s Health Practice-Based Research Network (WH-PBRN), embedded within VA, to employ a multisite card study to collect women Veterans’ perspectives about Complementary and Integrative Health (CIH) and to rapidly return findings to participating sites and partnered national policy-makers in support of a Learning Health System (LHS) wherein evidence generation informs ongoing improvement.

Methods:

VA primary care clinic clerks and nurses distributed anonymous surveys (patient feedback forms) at clinics for up to two weeks in fiscal year 2017, asking about CIH behavior and preferred delivery methods. We examined the project’s feasibility, representativeness, acceptability, and impact via a tracking system, national administrative data, debriefing notes, and three surveys of WH-PBRN Site Leads.

Results:

Twenty geographically diverse and largely representative VA Medical Centers and 11 Community-Based Outpatient Clinics volunteered to participate. Over six months, N = 1191 women Veterans responded (median 57; range 8–151 per site). In under three months, we returned local findings benchmarked against multisite findings to all participating sites and summary findings to national VA partners. Sites and partners disseminated results to clinical and leadership stakeholders, who then applied results as warranted.

Conclusions:

VA effectively mobilized an embedded PBRN to implement a timely, representative, acceptable and impactful operations project.

Implications:

Card studies by PBRNs within large, national healthcare systems can provide rapid feedback to participating sites and national leaders to guide policies, programs, and practices.

Level of Evidence:

Self-selected respondents could have biased results.

Retaining VA Women's Health Primary Care Providers: Work Setting Matters

BACKGROUND

When an experienced provider opts to leave a healthcare workforce (attrition), there are significant costs, both direct and indirect. Turnover of healthcare providers is underreported and understudied, despite evidence that it negatively impacts care delivery and negatively impacts working conditions for remaining providers. In the Veterans Affairs (VA) healthcare system, attrition of women's health primary care providers (WH-PCPs) threatens a specially trained workforce; it is unknown what factors contribute to, or protect against, their attrition.

OBJECTIVE

Based on evidence that clinic environment, adequate support resources, and workload affect provider burnout and intent to leave, we explored if such clinic characteristics predict attrition of WH-PCPs in the VA, to identify protective factors.

DESIGN

This analysis drew on two waves of existing national VA survey data to examine predictors of WH-PCP attrition, via logistic regression.

PARTICIPANTS

All 2,259 providers from 140 facilities VA-wide who were WH-PCPs on September 30, 2016.

MAIN MEASURES

The dependent variable was WH-PCP attrition in the following year. Candidate predictors were clinic environment (working in: a comprehensive women's health center, a limited women's health clinic, a general primary care clinic, or multiple clinic environments), availability of co-located specialty support resources (mental health, social work, clinical pharmacy), provider characteristics (gender, professional degree), and clinic workload (clinic sessions per week).

KEY RESULTS

Working exclusively in a comprehensive women's health center uniquely predicted significantly lower risk of WH-PCP attrition (adjusted odds ratio 0.40; CI 0.19-0.86).

CONCLUSIONS

A comprehensive women's health center clinical context may promote retention of this specially trained primary care workforce. Exploring potential mechanisms-e.g., shared mission, appropriate support to meet patients' needs, or a cohesive team environment-may inform broader efforts to retain front-line providers.

Mobilizing embedded research and operations partnerships to address harassment of women Veterans at VA medical facilities

Key insights: A: Addressing a complex problem like harassment in VA medical facilities requires committed, engaged collaboration at multiple levels of the organization. B: Timely feedback of initial research findings to operations partners enabled rapid and more responsive development of new programs and policies. C: Our research-clinical partnership has enabled us to pursue targeted change from the outset, while incorporating real-time findings from embedded researchers working to develop a comprehensive understanding of the problem.

Differences in body mass index based on self-reported versus measured data from women veterans

OBJECTIVE

The objective was to compare differences in body mass index (BMI) calculated with self-reported versus clinically measured pre-conception data from women veterans in California.

METHODS

Veterans Health Administration (VHA) and California state birth certificate data were used to develop a cohort of women who gave birth from 2007-2012 and had VHA data available to calculate BMI (N = 1,326 mothers, 1,473 births). Weighted Kappa statistics assessed concordance between self-reported and measured BMI. A linear mixed-effects model with maximum likelihood estimation, adjusted for mother as a random effect, assessed correlates of differences in BMI.

RESULTS

Mean BMI was in the overweight range based on self-reported (26.2 kg/m2, SD: 5.2) and measured (26.8 kg/m2, SD: 5.2) data. Weighted Kappa statistics indicated good agreement between self-reported and measured BMI (0.73, 95% CI: 0.70, 0.76). Compared to the normal weight group, groups with overweight or obesity were significantly more likely to have lower BMIs when calculated using self-reported versus measured heights and weights, in unadjusted and adjusted models. The finding was pronounced for class 3 obesity, which was associated with a BMI underestimation of 6.4 kg/m2.

CONCLUSIONS

Epidemiologic research that guides the clinical care of pregnant women should account for potential under-estimation of BMI in heavier women, and perform direct measurement where feasible.

Mental Health and Obesity Among Veterans: A Possible Need for Integrated Care

OBJECTIVE

The goal was to examine psychiatric diagnosis rates among a national cohort of primary care patients with and without obesity.

METHODS

The cohort was derived from national Veterans Health Administration data (women, N=342,262; men, N=4,524,787). Sex-stratified descriptive statistics characterized psychiatric diagnosis rates. Chi-square tests determined whether diagnosis rates differed by obesity status (α=0.001).

RESULTS

Rates of any psychiatric diagnosis were higher among women than among men and among people with obesity versus without obesity (women, 53.9% vs. 50.4%; men, 37.9% vs. 35.2%). Depression and posttraumatic stress disorder diagnosis rates were higher for people with obesity, and substance use disorder diagnosis rates were lower for people with obesity. Anxiety diagnosis rates were slightly lower among women with obesity versus women without obesity.

CONCLUSIONS

Programs simultaneously addressing weight management and mental health could address the psychiatric comorbidities observed among people with obesity. Women are most likely to need these services.

Obesity and Health Care Experiences among Women and Men Veterans

BACKGROUND

Obesity is highly stigmatized, especially for women, and therefore may negatively affect health care experiences. Past findings on the relationship between obesity and health care experiences are mixed, perhaps because few studies examine relationships by gender and obesity class. Our objective was to evaluate whether women and men with more severe obesity report worse health care experiences related to Veterans Health Administration (VA) care.

METHODS

Health care experiences (self-management support, mental health assessments, office staff courtesy, communication with providers) and overall provider ratings were assessed with the 2014 VA Survey of Health Care Experiences of Patients. Using multiple regression analyses (n = 13,462 women, n = 268,180 men), we assessed associations among obesity classes, health care experiences, and overall provider ratings, adjusting for sociodemographic, health, and primary care use characteristics.

RESULTS

The greatest differences in health care experiences between patients with and without obesity were in self-management support experiences, which were more favorable among women and men of all obesity classes. There were gender differences in associations between obesity and mental health assessments: for men, but not women, those in any obesity class gave higher ratings than those without obesity. For most other health care experiences and provider ratings, men with obesity reported slightly less favorable experiences than those without. There was no consistent pattern for women.

CONCLUSIONS

It is promising that VA patients with obesity report more self-management support, given the behavior change required for weight management. Lower health care experience and provider ratings among men with obesity suggest a need to further investigate possible obesity-related stigma in VA primary care.

Four Decades after War: Incident Diabetes among Women Vietnam-Era Veterans in the HealthViEWS Study

OBJECTIVES

We analyzed long-term differences in incident diabetes associated with military service in a warzone among women who served during the Vietnam War era.

METHODS

For HealthViEWS, the largest later-life study of women Vietnam War-era U.S. veterans, a population-based retrospective cohort who served during 1965-1973 completed a health interview in 2011-2012. This cohort included women deployed to Vietnam, near Vietnam, or who served primarily in the United States. We hypothesized a warzone exposure gradient: Vietnam (highest exposure), near Vietnam, and the United States (lowest exposure). We used an extended Cox regression to test for differences in incident diabetes by location of wartime service.

RESULTS

Of 4,503 women in the analysis, 17.7% developed diabetes. Adjusting for demographics and military service characteristics, hazard of incident diabetes was significantly lower initially in the Vietnam group compared with the U.S. group (hazard ratio, 0.33; 95% confidence interval, 0.15-0.69). However, lower diabetes hazard in the Vietnam group was not constant over time; rather, hazard accumulated faster over time in the Vietnam group compared with the U.S. group (hazard ratio, 1.38; 95% confidence interval, 1.11-1.72). No significant difference in diabetes hazard was found between the near Vietnam and U.S. groups. Older age during military service, minority race/ethnicity, and lower military rank were associated with a higher diabetes hazard.

CONCLUSIONS

Women deployed to a warzone might have protective health factors that lower risk for diabetes early in their military career, but delivery systems for long-term health should consider that a lower risk for chronic diseases like diabetes can wane quickly in the decades that follow warzone service.

Substance Use Disorder-Related Disparities in Patient Experiences of Primary Care

Purpose: To assess disparities in primary care experiences for patients with a substance use disorder (SUD) diagnosis.

Methods: We assessed differences in Veterans Health Administration (VA) primary care patients' experiences using data from the 2014 outpatient VA Patient-Centered Medical Home Survey of Healthcare Experiences of Patients (SHEP; N=286,026). We obtained patient demographics and diagnoses from VA electronic medical record data.

Results: Patients with an SUD diagnosis reported worse experiences for 8 of 12 SHEP measures, including access, provider communication, and information received (p<0.05).

Conclusion: Targeted strategies may be needed to ensure patients with SUD have favorable primary care experiences.

Coordinating Care Across VA Providers and Settings: Policy and Research Recommendations from VA's State of the Art Conference

Delivering well-coordinated care is essential for optimizing clinical outcomes, enhancing patient care experiences, minimizing costs, and increasing provider satisfaction. The Veterans Health Administration (VA) has built a strong foundation for internally coordinating care. However, VA faces mounting internal care coordination challenges due to growth in the number of Veterans using VA care, high complexity in Veterans' care needs, the breadth and depth of VA services, and increasing use of virtual care. VA's Health Services Research and Development service with the Office of Research and Development held a conference assessing the state-of-the-art (SOTA) on care coordination. One workgroup within the SOTA focused on coordination between VA providers for high-need Veterans, including (1) Veterans with multiple chronic conditions; (2) Veterans with high-intensity, focused, specialty care needs; (3) Veterans experiencing care transitions; (4) Veterans with severe mental illness; (5) and Veterans with homelessness and/or substance use disorders. We report on this workgroup's recommendations for policy and organizational initiatives and identify questions for further research. Recommendations from a separate workgroup on coordinating VA and non-VA care are contained in a companion paper. Leaders from research, clinical services, and VA policy will need to partner closely as they develop, implement, assess, and spread effective practices if VA is to fully realize its potential for delivering highly coordinated care to every Veteran.

Racial/Ethnic Disparities in Mortality Across the Veterans Health Administration

Purpose: Equal-access health care systems such as the Veterans Health Administration (VHA) reduce financial and nonfinancial barriers to care. It is unknown if such systems mitigate racial/ethnic mortality disparities, such as those well documented in the broader U.S. population. We examined racial/ethnic mortality disparities among VHA health care users, and compared racial/ethnic disparities in VHA and U.S. general populations. Methods: Linking VHA records for an October 2008 to September 2009 national VHA user cohort, and National Death Index records, we assessed all-cause, cancer, and cardiovascular-related mortality through December 2011. We calculated age-, sex-, and comorbidity-adjusted mortality hazard ratios. We computed sex-stratified, age-standardized mortality risk ratios for VHA and U.S. populations, then compared racial/ethnic disparities between the populations. Results: Among VHA users, American Indian/Alaskan Natives (AI/ANs) had higher adjusted all-cause mortality, whereas non-Hispanic Blacks had higher cause-specific mortality versus non-Hispanic Whites. Asians, Hispanics, and Native Hawaiian/Other Pacific Islanders had similar, or lower all-cause and cause-specific mortality versus non-Hispanic Whites. Mortality disparities were evident in non-Hispanic-Black men compared with non-Hispanic White men in both VHA and U.S. populations for all-cause, cardiovascular, and cancer (cause-specific) mortality, but disparities were smaller in VHA. VHA non-Hispanic Black women did not experience the all-cause and cause-specific mortality disparity present for U.S. non-Hispanic Black women. Disparities in all-cause and cancer mortality existed in VHA but not in U.S. population AI/AN men. Conclusion: Patterns in racial/ethnic disparities differed between VHA and U.S. populations, with fewer disparities within VHAs equal-access system. Equal-access health care may partially address racial/ethnic mortality disparities, but other nonhealth care factors should also be explored.

Selection of Higher Risk Pregnancies into Veterans Health Administration Programs: Discoveries from Linked Department of Veterans Affairs and California Birth Data

OBJECTIVE

To describe variation in payer and outcomes in Veterans' births.

DATA/SETTING

Secondary data analyses of deliveries in California, 2000-2012.

STUDY DESIGN

We performed a retrospective, population-based study of all live births to Veterans (confirmed via U.S. Department of Veterans Affairs (VA) enrollment records), to identify payer and variations in outcomes among: (1) Veterans using VA coverage and (2) Veteran vs. all other births. We calculated odds ratios (aOR) adjusted for age, race, ethnicity, education, and obstetric demographics.

METHODS

We anonymously linked VA administrative data for all female VA enrollees with California birth records.

PRINCIPAL FINDINGS

From 2000 to 2012, we identified 17,495 births to Veterans. VA covered 8.6 percent (1,508), Medicaid 17.3 percent, and Private insurance 47.6 percent. Veterans who relied on VA health coverage had more preeclampsia (aOR 1.4, CI 1.0-1.8) and more cesarean births (aOR 1.2, CI 1.0-1.3), and, despite similar prematurity, trended toward more neonatal intensive care (NICU) admissions (aOR 1.2, CI 1.0-1.4) compared to Veterans using other (non-Medicaid) coverage. Overall, Veterans' birth outcomes (all-payer) mirrored California's birth outcomes, with the exception of excess NICU care (aOR 1.15, CI 1.1-1.2).

CONCLUSIONS

VA covers a higher risk fraction of Veterans' births, justifying maternal care coordination and attention to the maternal-fetal impacts of Veterans' comorbidities.

Use of Veterans Health Administration Mental Health and Substance Use Disorder Treatment After Exiting Prison: The Health Care for Reentry Veterans Program

The Veterans Health Administration (VA) Health Care for Reentry Veterans (HCRV) program links veterans exiting prison with treatment. Among veterans served by HCRV, national VA clinical data were used to describe contact with VA health care, and mental health and substance use disorder diagnoses and treatment use. Of veterans seen for an HCRV outreach visit, 56 % had contact with VA health care. Prevalence of mental health disorders was 57 %; of whom 77 % entered mental health treatment within a month of diagnosis. Prevalence of substance use disorders was 49 %; of whom 37 % entered substance use disorder treatment within a month of diagnosis. For veterans exiting prison, increasing access to VA health care, especially for rural veterans, and for substance use disorder treatment, are important quality improvement targets.

Practice-based research networks add value to evidence-based quality improvement

Background

Evidence-Based Quality Improvement (EBQI) is a systematic, multilevel approach to implementing research evidence into clinical settings. Little is known about EBQI effectiveness in the context of Practice-Based Research Networks (PBRNs), which are themselves designed to foster practice-based change. We evaluated EBQI implementation in a PBRN setting to determine the extent to which the PBRN infrastructure added value.

METHODS

We conducted a four-site cluster randomized trial of an EBQI approach to tailoring an evidence-based gender awareness curriculum in the VA Women’s Health PBRN (WH-PBRN). After curriculum implementation, site teams identified impacts of the WH-PBRN context on EBQI processes using qualitative methods, including a formal review of project call minutes, post-project debriefing calls, and structured site team input. WH-PBRN site feedback was mapped to the Replicating Effective Programs implementation phases: pre-condition, pre-implementation, implementation, and maintenance/evolution.

RESULTS

The pre-condition phase benefited from the existing WH-PBRN research-clinician relationships to facilitate stakeholder engagement and build project buy-in at local sites. During pre-implementation, differences across WH-PBRN sites offered variations in local tailoring of EBQI elements. The WH-PBRN Coordinating Center helped resolve process complexities stemming from local resource differences and the sharing of mid-project adaptations during implementation. Local efforts were amplified in the maintenance phase by WH-PBRN dissemination of findings.

Conclusions

The PBRN strengthened multi-site EBQI activities across all implementation phases.

Implications

PBRNs contribute to the uptake of evidence into everyday practice, and may serve as an important component of the future implementation of evidence-based initiatives. Level of evidence: V.

Racial And Ethnic Disparities Persist At Veterans Health Administration Patient-Centered Medical Homes

Patient-centered medical homes are widely promoted as a primary care delivery model that achieves better patient outcomes. It is unknown if their benefits extend equally to all racial/ethnic groups. In 2010 the Veterans Health Administration, part of the Department of Veterans Affairs (VA), began implementing patient-centered medical homes nationwide. In 2009 significant disparities in hypertension or diabetes control were present for most racial/ethnic groups, compared with whites. In 2014 hypertension disparities were similar for blacks, had become smaller but remained significant for Hispanics, and were no longer significant for multiracial veterans, whereas disparities had become significant for American Indians/Alaska Natives and Native Hawaiians/other Pacific Islanders. By contrast, in 2014 diabetes disparities were similar for American Indians/Alaska Natives, blacks, and Hispanics, and were no longer significant for Native Hawaiians/other Pacific Islanders. We found that the modest benefits of the VA's implementation of patient-centered medical homes were offset by competing multifactorial external, health system, provider, and patient factors, such as increased patient volume. To promote health equity, health care innovations such as patient-centered medical homes should incorporate tailored strategies that account for determinants of racial/ethnic variations. Evaluations of patient-centered medical homes should monitor outcomes for racial/ethnic groups.

Post-traumatic Stress Disorder and Antepartum Complications: a Novel Risk Factor for Gestational Diabetes and Preeclampsia

BACKGROUND

Prior work shows that Post-traumatic Stress Disorder (PTSD) predicts an increased risk of preterm birth, but the causal pathway(s) are uncertain. We evaluate the associations between PTSD and antepartum complications to explore how PTSD's pathophysiology impacts pregnancy.

METHODS

This retrospective cohort analysis of all Veterans Health Administration (VA)-covered deliveries from 2000-12 used the data of VA clinical and administration. Mothers with current PTSD were identified using the ICD-9 diagnostic codes (i.e. code present during the antepartum year), as were those with historical PTSD. Medical and administrative data were used to identify the relevant obstetric diagnoses, demographics and health, and military deployment history. We used Poisson regression with robust error variance to derive the adjusted relative risk estimates (RR) for the association of PTSD with five clinically relevant antepartum complications [gestational diabetes (GDM), preeclampsia, gestational hypertension, growth restriction, and abruption]. Secondary outcomes included proxies for obstetric complexity (repeat hospitalisation, prolonged delivery hospitalisation, and caesarean delivery).

RESULTS

Of the 15 986 singleton deliveries, 2977 (19%) were in mothers with PTSD diagnoses (1880 (12%) current PTSD). Mothers with the complication GDM were 4.9% and those with preeclampsia were 4.6% of all births. After adjustment, a current PTSD diagnosis (reference = no PTSD) was associated with an increased risk of GDM (RR 1.4, 95% confidence interval (CI) 1.2, 1.7) and preeclampsia (RR 1.3, 95% CI 1.1, 1.6). PTSD also predicted prolonged (>4 day) delivery hospitalisation (RR 1.2, 95% CI 1.01, 1.4), and repeat hospitalisations (RR 1.4, 95% CI 1.2, 1.6), but not caesarean delivery.

CONCLUSIONS

The observed association of PTSD with GDM and preeclampsia is consistent with our nascent understanding of PTSD as a disruptor of neuroendocrine and cardiovascular health.

Assessment of a Revised Wartime Experiences Scale for Vietnam-Era Women: The Health of Vietnam-Era Women's Study (HealthViEWS)

PURPOSE

Few wartime experiences scales capture unique issues related to women's service, address their military roles, or have been validated with women. The Women's Wartime Stressor Scale was developed for use with women who served during the Vietnam era, primarily as nurses in Vietnam. We revised this measure by modifying existing items, adding new items, and revising response formats to create a scale less nursing specific and nondeployment specific, and conducted a preliminary assessment of the revised scale.

METHODS

The Women's Wartime Exposure Scale-Revised (WWES-R) was included in a mail survey as part of the U.S. Department of Veterans Affairs Health of Vietnam-Era Women's Study (HealthViEWS) study. Construct and criterion validity, and internal consistency, were assessed with a sample of 4,839 women veterans using exploratory factor analysis, analysis of variance, and multiple linear regression.

RESULTS

Six wartime experience factors consistent with previous research were identified and scales were created based on salient item loadings. Compared with women serving in the United States, women serving in Vietnam had higher mean scores on all scales, and nurses had significantly higher scores on three scales than non-nurses.

CONCLUSIONS

Evaluation of the WWES-R suggests service and/or deployment location and service in a military health care versus a non-health care role may predict women veterans' reports of certain wartime experiences. Further psychometric evaluation of the WWES-R is recommended with later era veterans and through comparisons to other wartime exposure measures.

The Obesity Epidemic in the Veterans Health Administration: Prevalence Among Key Populations of Women and Men Veterans

BACKGROUND

Most US adults are overweight or obese. Understanding differences in obesity prevalence across subpopulations could facilitate the development and dissemination of weight management services.

OBJECTIVES

To inform Veterans Health Administration (VHA) weight management initiatives, we describe obesity prevalence among subpopulations of VHA patients.

DESIGN

Cross-sectional descriptive analyses of fiscal year 2014 (FY2014) national VHA administrative and clinical data, stratified by gender. Differences ≥5% higher than the population mean were considered clinically significant.

PARTICIPANTS

Veteran VHA primary care patients with a valid weight within ±365 days of their first FY2014 primary care visit, and a valid height (98% of primary care patients).

MAIN MEASURES

We used VHA vital signs data to ascertain height and weight and calculate body mass index, and VHA outpatient, inpatient, and fee basis data to identify sociodemographic- and comorbidity-based subpopulations.

KEY RESULTS

Among nearly five million primary care patients (347,112 women, 4,567,096 men), obesity prevalence was 41% (women 44%, men 41%), and overweight prevalence was 37% (women 31%, men 38%). Across the VHA's 140 facilities, obesity prevalence ranged from 28% to 49%. Among gender-stratified subpopulations, obesity prevalence was high among veterans under age 65 (age 18-44: women 40%, men 46%; age 45-64: women 49%, men 48%). Obesity prevalence varied across racial/ethnic and comorbidity subpopulations, with high obesity prevalence among black women (51%), women with schizophrenia (56%), and women and men with diabetes (68%, 56%).

CONCLUSIONS

Overweight and obesity are common among veterans served by the VHA. VHA's weight management initiatives have the potential to avert long-term morbidity arising from obesity-related conditions. High-risk groups-such as black women veterans, women veterans with schizophrenia, younger veterans, and Native Hawaiian/Other Pacific Islander and American Indian/Alaska Native veterans-may require particular attention to ensure that systems improvement efforts at the population level do not inadvertently increase health disparities.

Impact of Baseline Stroke Risk and Bleeding Risk on Warfarin International Normalized Ratio Control in Atrial Fibrillation (from the TREAT-AF Study)

Warfarin prevents stroke and prolongs survival in patients with atrial fibrillation and flutter (AF, collectively) but can cause hemorrhage. The time in international normalized ratio (INR) therapeutic range (TTR) mediates stroke reduction and bleeding risk. This study sought to determine the relation between baseline stroke, bleeding risk, and TTR. Using data from The Retrospective Evaluation and Assessment of Therapies in Atrial Fibrillation (TREAT-AF) retrospective cohort study, national Veterans Health Administration records were used to identify patients with newly diagnosed AF from 2003 to 2012 and subsequent initiation of warfarin. Baseline stroke and bleeding risk was determined by calculating CHA₂DS₂-VASc and HAS-BLED scores, respectively. Main outcomes were first-year and long-term TTR and INR monitoring rate. In 167,190 patients, the proportion of patients with TTR (>65%) decreased across increasing strata of CHA₂DS₂-VASc and HAS-BLED. After covariate adjustment, odds of achieving TTR >65% were significantly associated with high CHA₂DS₂-VASc or HAS-BLED score. INR monitoring rate was similar across risk strata. In conclusion, increased baseline stroke and bleeding risk is associated with poor INR control, despite similar rates of INR monitoring. These findings may paradoxically limit warfarin's efficacy and safety in high-risk patients and may explain observed increased bleeding and stroke rates in this cohort.

Systems innovation model: an integrated interdisciplinary team approach pre- and post-bariatric surgery at a veterans affairs (VA) medical center

BACKGROUND

Provision of bariatric surgery in the Veterans Health Administration must account for obese veterans' co-morbidity burden and the geographically dispersed location of patients relative to Veterans Affairs (VA) bariatric centers.

OBJECTIVES

To evaluate a collaborative, integrated, interdisciplinary bariatric team of surgeons, bariatricians, psychologists, dieticians, and physical therapists working in a hub-and-spokes care model, for pre- and post-bariatric surgery assessment and management.

METHODS

This is a description of an interdisciplinary clinic and bariatric program at a VA healthcare system and a report on program evaluation findings. Retrospective data of a prospective database was abstracted. For program evaluation, we abstracted charts to characterize patient data and conducted a patient survey.

RESULTS

Since 2009, 181 veterans have undergone bariatric surgery. Referrals came from 7 western U.S. states. Mean preoperative body mass index was 46 kg/m² (maximum 71). Mean age was 53 years, with 33% aged>60 years; 79% were male. Medical co-morbidity included diabetes (70%), hypertension (85%), and lower back or extremity joint pain (84%). A psychiatric diagnosis was present in 58%. At 12 months, follow-up was 81% and percent excess body mass index loss was 50.5%. Among 54 sequential clinic patients completing anonymous surveys, overall satisfaction with the interdisciplinary team approach and improved quality of life were high (98% and 94%, respectively).

CONCLUSION

The integrated, interdisciplinary team approach using a hub-and-spokes model is well suited to the VA bariatric surgery population, with its heavy burden of medical and mental health co-morbidity and its system of geographically dispersed patients receiving treatment at specialty centers. As the VA seeks to expand the use of bariatric surgery as an option for obese veterans, interdisciplinary models crafted to address case complexity, care coordination, and long-term outcomes should be part of policy planning efforts.

Warfarin utilisation and anticoagulation control in patients with atrial fibrillation and chronic kidney disease

OBJECTIVE

To evaluate warfarin prescription, quality of international normalised ratio (INR) monitoring and of INR control in patients with atrial fibrillation (AF) and chronic kidney disease (CKD).

METHODS

We performed a retrospective cohort study of patients with newly diagnosed AF in the Veterans Administration (VA) healthcare system. We evaluated anticoagulation prescription, INR monitoring intensity and time in and outside INR therapeutic range (TTR) stratified by CKD.

RESULTS

Of 123 188 patients with newly diagnosed AF, use of warfarin decreased with increasing severity of CKD (57.2%-46.4%), although it was higher among patients on dialysis (62.3%). Although INR monitoring intensity was similar across CKD strata, the proportion with TTR≥60% decreased with CKD severity, with only 21% of patients on dialysis achieving TTR≥60%. After multivariate adjustment, the magnitude of TTR reduction increased with CKD severity. Patients on dialysis had the highest time markedly out of range with INR <1.5 or >3.5 (30%); 12% of INR time was >3.5, and low TTR persisted for up to 3 years.

CONCLUSIONS

There is a wide variation in anticoagulation prescription based on CKD severity. Patients with moderate-to-severe CKD, including dialysis, have substantially reduced TTR, despite comparable INR monitoring intensity. These findings have implications for more intensive warfarin management strategies in CKD or alternative therapies such as direct oral anticoagulants.

Prevalence and risk of fracture diagnoses in women across the adult life span: a national cross-sectional study

In a national sample of women veterans, the rate of lower limb fracture diagnosis was the highest across ages 18-74 years; rates of fracture diagnosis of other skeletal sites peaked in women aged 75+. Women with two or more primary care visits or mental healthcare visits had elevated odds of fracture diagnosis.

INTRODUCTION

We assessed the prevalence and healthcare utilization characteristics associated with a diagnosis of any fracture in women of all adult ages within the Veterans Health Administration.

METHODS

In 344,488 women during fiscal year 2012, logistic regression models for fracture diagnosis included age, race/ethnicity, residence, number of primary care visits, number of mental healthcare visits, and degree of service-connected disability.

RESULTS

Lower limb fracture diagnosis was most prevalent across ages 18-74 years and peaked in women aged 55-64 years. In women aged 75+, the prevalence rates of fracture diagnosis at the hip (102, 95 % CI = 88-115 per 10,000 women), upper limb (100, 95 % CI = 87-114 per 10,000 women), and lower limb (84, 95 % CI = 72-97 per 10,000 women) were the highest. Fractures at other skeletal sites peaked in those aged 75+ years. Black women had the lowest odds of a fracture diagnosis, followed by Asian/Pacific Islander and Hispanic women compared to non-Hispanic White (by 25-51 %, P < 0.05). Having two or more primary care visits or any mental health visit was each associated with an increased risk. Women with five or more primary care visits had a 3.36-fold (95 % CI = 3.02-3.75) greater odds than those with no such visit, and separately, women with five or more mental health visits had a 1.51-fold (95 % CI = 1.43-1.60) greater odds. Women with a fracture diagnosis had higher overall healthcare costs than those without (P < 0.001).

CONCLUSIONS

Prevalence of fracture diagnosis differed by age, race/ethnicity, and skeletal site of fracture. Fracture diagnosis may identify women veterans with greater overall healthcare needs.

Receptivity to alcohol-related care among U.S. women Veterans with alcohol misuse

Previous research indicates women Veterans have a potentially large, unmet need for alcohol-related care but are under-represented in treatment settings. The purpose of this study was to identify factors associated with women Veterans' receptivity to a recommendation for alcohol-related care when they present to Veterans Affairs (VA) primary care with alcohol misuse. Semi-structured interviews were conducted from 2012-2013 with 30 women Veterans at two VA facilities who screened positive for alcohol misuse during a primary care visit and discussed their alcohol use with their primary-care provider. Qualitative analyses identified 9 themes women used to describe what affected their receptivity to a recommendation for alcohol-related care (i.e., VA specialty substance use disorder services). The most common themes positively associated with women's receptivity included self-appraisal of their drinking behavior as more severe, the provider's presentation of treatment options, availability of gender-specific services, and worse physical and mental health. The themes identified here may have important implications for the clinical strategies providers can use to present alcohol-related care options to women Veterans to facilitate their use of care. These strategies include educating women about the health effects of alcohol misuse and increasing providers' knowledge about available care options (within the care organization or the community), including the availability of gender-specific services.

Receipt of pharmacotherapy for opioid use disorder by justice-involved U.S. Veterans Health Administration patients

BACKGROUND

Pharmacotherapy - methadone, buprenorphine, or naltrexone - is an evidence-based treatment for opioid use disorder, but little is known about receipt of these medications among veterans involved in the justice system. The current study examines receipt of pharmacotherapy for opioid use disorder among veterans with a history of justice involvement at U.S. Veterans Health Administration (VHA) facilities compared to veterans with no justice involvement.

METHODS

Using national VHA clinical and pharmacy records, we conducted a retrospective cohort study of veterans with an opioid use disorder diagnosis in fiscal year 2012. Using a mixed-effects logistic regression model, we examined receipt of pharmacotherapy in the 1-year period following diagnosis as a function of justice involvement, adjusting for patient and facility characteristics.

RESULTS

The 1-year rate of receipt for pharmacotherapy for opioid use disorder was 27% for prison-involved veterans, 34% for jail/court-involved veterans, and 33% for veterans not justice-involved. Compared to veterans not justice-involved, those prison-involved had 0.75 lower adjusted odds (95% confidence interval [CI]: 0.65-0.87) of receiving pharmacotherapy whereas jail/court-involved veterans did not have significantly different adjusted odds.

CONCLUSIONS

Targeted efforts to improve receipt of pharmacotherapy for opioid use disorder among veterans exiting prison is needed as they have lower odds of receiving these medications.

Racial Differences in Quality of Anticoagulation Therapy for Atrial Fibrillation (from the TREAT-AF Study)

The influence of race on quality of anticoagulation control is not well described. We examined the association between race, international normalized ratio (INR) monitoring intensity, and INR control in warfarin-treated patients with atrial fibrillation (AF). Using data from the Veterans Health Administration (VHA), we performed a retrospective cohort study of 184,161 patients with a new diagnosis of AF/flutter from 2004 to 2012 who received any VHA prescription within 90 days of diagnosis. The primary predictor was race, ascertained from multiple VHA and linked Medicare demographic files. The primary outcome was first-year and long-term time in therapeutic range (TTR) of INR 2.0 to 3.0. Secondary outcomes were INR monitoring intensity and warfarin persistence. Of the 116,021 patients who received warfarin in the cohort, INR monitoring intensity was similar across racial groups. However, TTR was lowest in blacks and highest in whites (first year 0.49 ± 0.23 vs 0.57 ± 0.21, p <0.001; long term 0.52 ± 0.20 vs 0.59 ± 0.18, p <0.001); 64% of whites and 49% of blacks had long-term TTR >55% (p <0.001). After adjusting for site and patient-level covariates, black race was associated with lower first-year and long-term TTRs (4.2% and 4.1% below the conditional mean, relative to whites; p <0.0001 for both). One-year warfarin persistence was slightly lower in blacks compared to whites (58% vs 60%, p <0.0001). In conclusion, in patients with AF anticoagulated with warfarin, differences in INR control are most evident among blacks, underscoring the need to determine if other types of intensive management or warfarin alternatives may be necessary to improve anticoagulation among vulnerable AF populations.

Effectiveness of an Evidence-Based Quality Improvement Approach to Cultural Competence Training: The Veterans Affairs' "Caring for Women Veterans" Program

INTRODUCTION

Although providing culturally sensitive health care is vitally important, there is little consensus regarding the most effective strategy for implementing cultural competence trainings in the health care setting. Evidence-based quality improvement (EBQI), which involves adapting evidence-based practices to meet local needs, may improve uptake and effectiveness of a variety of health care innovations. Yet, to our knowledge, EBQI has not yet been applied to cultural competence training. To evaluate whether EBQI could enhance the impact of an evidence-based training intended to improve veterans affairs health care staff gender sensitivity and knowledge (Caring for Women Veterans; CWV), we compared the reach and effectiveness of EBQI delivery versus standard web-based implementation strategies of CWV and assessed barriers and facilitators to EBQI implementation.

METHODS

Workgroups at four diverse veterans affairs health care sites were randomized to either an EBQI or standard web-based implementation condition (SI). All EBQI sites selected a group-based implementation strategy. Employees (N = 84) completed pretraining and posttraining assessments of gender sensitivity and knowledge, and focus groups/interviews were conducted with leadership and staff before and after implementation.

RESULTS

Reach of CWV was greater in the EBQI condition versus the SI condition. Whereas both gender sensitivity and knowledge improved in the EBQI condition, only gender sensitivity improved in the SI condition. Qualitative analyses revealed that the EBQI approach was well received, although a number of barriers were identified.

DISCUSSION

Findings suggest that EBQI can enhance the uptake and effectiveness of employee trainings. However, the decision to pursue EBQI must be informed by a consideration of available resources.

Anticoagulation in atrial fibrillation: impact of mental illness

OBJECTIVES

To characterize warfarin eligibility and receipt among Veterans Health Administration (VHA) patients with and without mental health conditions (MHCs).

STUDY DESIGN

Retrospective cohort study.

METHODS

This observational study identified VHA atrial fibrillation (AF) patients with and without MHCs in 2004. We examined unadjusted MHC-related differences in warfarin eligibility and warfarin receipt among warfarin-eligible patients, using logistic regression for any MHC and for specific MHCs (adjusting for sociodemographic and clinical characteristics).

RESULTS

Of 125,670 patients with AF, most (96.8%) were warfarin-eligible based on a CHADS2 stroke risk score. High stroke risk and contraindications to anticoagulation were both more common in patients with MHC. Warfarin-eligible patients with MHC were less likely to receive warfarin than those without MHC (adjusted odds ratio [AOR], 0.90; 95% CI, 0.87-0.94). The association between MHC and warfarin receipt among warfarin-eligible patients varied by specific MHC. Patients with anxiety disorders (AOR, 0.86; 95% CI, 0.80-0.93), psychotic disorders (AOR, 0.77; 95% CI, 0.65-0.90), and alcohol use disorders (AOR 0.62, 95% CI 0.54-0.72) were less likely to receive warfarin than patients without these conditions, whereas patients with depressive disorders and posttraumatic stress disorder were no less likely to receive warfarin than patients without these conditions.

CONCLUSIONS

Compared with patients with AF without MHCs, those with MHCs are less likely to be eligible for warfarin receipt and, among those eligible, are less likely to receive such treatment. Although patients with AF with MHC need careful assessment of bleeding risk, this finding suggests potential missed opportunities for more intensive therapy among some individuals with MHCs.
