Project description:PurposeWomen Veterans have unique healthcare needs and often experience comorbid health conditions. Despite this, many women Veterans are not enrolled in the Veterans Health Administration (VHA) and do not use VHA services. Underutilization of VHA services may be particularly prevalent among rural women Veterans, who may experience unique barriers to using VHA care. Nonetheless, knowledge of rural women Veterans and their experiences remains limited. We sought to understand rural women Veterans' perceptions and needs related to VHA healthcare, including barriers to enrolling in and using VHA services, and perspectives on how to communicate with rural women Veterans about VHA services.MethodsRural women Veterans were recruited through community engagement with established partners and a mass mailing to rural women Veterans not enrolled in or using VHA healthcare. Ten virtual focus groups were conducted with a total of twenty-nine rural women Veterans (27 not enrolled in VHA care and 2 who had not used VHA care in the past 5 years) in 2021. A thematic inductive analytic approach was used to analyze focus group transcripts.FindingsPrimary themes regarding rural women Veterans' perceptions of barriers to enrollment and use of VHA healthcare included: (1) poor communication about eligibility and the process of enrollment; (2) belief that VHA does not offer sufficient women's healthcare services; and (3) inconvenience of accessing VHA facilities.ConclusionAlthough VHA has substantially expanded healthcare services for women Veterans, awareness of such services and the nuances of eligibility and enrollment remains an impediment to enrolling in and using VHA healthcare among rural women Veterans. Recommended strategies include targeted communication with rural women Veterans not enrolled in VHA care to increase their awareness of the enrollment process, eligibility, and expansion of women's healthcare services. Creative strategies to address access and transportation barriers in rural locations are also needed.

Project description:BackgroundOn April 23, 2014, US media outlets broadcast reports of excessive wait times and "secret" waitlists at some Veterans Affairs (VA) hospitals, precipitating legislation to increase Veterans' access to private sector health care.ObjectiveThe aims were to assess changes in Veterans' distrust in the VA health care system before and after the media coverage and explore sex and racial/ethnic differences in the temporal patterns.MethodsVeterans completed semistructured interviews on health care satisfaction from June 2013 to January 2015, including a validated scale of health system distrust (range: 1-5). We used linear splines with knots at 90-day intervals to assess changes in distrust before and after April 23, 2014 ("day 0") in linear mixed models. To explore sex and racial/ethnic differences in temporal patterns, we stratified models by sex and tested for interactions of race/ethnicity with time.ResultsFor women (n=600), distrust scores (mean=2.09) increased by 0.45 in days 0-90 (P<0.01), then decreased by 0.45 in days 90-180 (P<0.01). Among men (n=575), distrust scores (mean=2.05) increased by 0.18 in days 0-90 (P=0.059). Distrust levels were significantly higher for Black versus White women (time adjusted mean difference=0.21) and for Black and Hispanic versus White men (differences=0.26 and 0.18). However, the temporal patterns did not vary by race/ethnicity for women or men (interaction P=0.85 and 0.21, respectively).ConclusionsHealth system distrust increased in women following media coverage of VA access problems and was higher in Black/Hispanic versus White Veterans at all time periods. Such perceptions could influence Veteran decisions to seek health care in the community rather than VA.

Project description:BackgroundClopidogrel use after drug-eluting stent (DES) coronary artery implantation is essential for the prevention of early in-stent thrombosis, but clopidogrel use among older DES recipients has not been widely studied. We sought to identify characteristics associated with failure to fill a clopidogrel prescription and to examine the relationship between a clopidogrel prescription fill and hospitalization for acute myocardial infarction (AMI) or death.Methods and resultsThis study was a retrospective analysis of administrative data (20% sample) of 15 996 Medicare Part D enrollees who received a DES in 2006 to 2007. We modeled the adjusted probability and odds of clopidogrel prescription fill within 7 and 90 days of discharge and its association with AMI hospitalization or death. Of the study sample, 19.7% did not fill a clopidogrel prescription within 7 days of discharge, falling to 13.3% by day 90. The adjusted probability of filling a clopidogrel prescription within 7 or 90 days of discharge was lower for patients with dementia (20.2% less likely; 95% CI, 10.4%-30.1%), depression (10.7% less likely; 95% CI, 6.9%-14.5%), age >84 years compared to age 65 to 69 years (10.6% less likely; 95% CI, 8.6%-12.7%), black race (6.6% less likely; 95% CI, 4.2%-9.0%), intermediate levels of medication cost share (5.2% less likely; 95% CI, 2.9%-7.6%), and female sex (3.3% less likely; 95% CI, 2.1%-4.5%). It was higher for patients initially hospitalized for an AMI (12.5% more likely; 95% CI, 11.3%-13.6%). Failure to fill a clopidogrel prescription within 7 days of discharge was associated with a higher adjusted odds ratio of death during days 8 to 90 (2.44; 95% CI, 1.76-3.38) but was not associated with an increased risk of hospitalization for AMI.ConclusionsOne in 5 patients failed to fill a prescription for clopidogrel at 7 days after DES placement, and 1 in 7 failed to do so by 3 months. Individual characteristics available at the time of hospital discharge were associated with a clopidogrel prescription fill. Those characteristics most strongly associated with nonadherence, including age >84 years, not having an AMI, depression, and dementia, may guide clinicians and health systems seeking to target this high-risk population and improve health outcomes after percutaneous coronary intervention.

Project description:BackgroundEmpirical antibiotic use is common in the hospital. Here, we characterize patterns of antibiotic use, infectious diagnoses, and microbiological laboratory results among hospitalized patients and aim to quantify the proportion of antibiotic use that is potentially attributable to specific bacterial pathogens.MethodsWe conducted an observational study using electronic health records from acute care facilities in the US Veterans Affairs Healthcare System. From October 2017 to September 2018, 482 381 hospitalizations for 332 657 unique patients that met all criteria were included. At least 1 antibiotic was administered at 202 037 (41.9%) of included hospital stays. We measured frequency of antibiotic use, microbiological specimen collection, and bacterial isolation by diagnosis category and antibiotic group. A tiered system based on specimen collection sites and diagnoses was used to attribute antibiotic use to presumptive causative organisms.ResultsSpecimens were collected at 130 012 (64.4%) hospitalizations with any antibiotic use, and at least 1 bacterial organism was isolated at 35.1% of these stays. Frequency of bacterial isolation varied widely by diagnosis category and antibiotic group. Under increasingly lenient criteria, 10.2%-31.4% of 974 733 antibiotic days of therapy could be linked to a potential bacterial pathogen.ConclusionsOverall, the vast majority of antibiotic use could be linked to either an infectious diagnosis or microbiological specimen. Nearly one-half of antibiotic use occurred when there was a specimen collected but no bacterial organism identified, underscoring the need for rapid and improved diagnostics to optimize antibiotic use.

Project description:BACKGROUND:Veterans with healthcare needs utilize both Veterans Health Administration (VA) and non-VA hospitals. These dual-use veterans are at high risk of adverse outcomes due to the lack of coordination for safe transitions. OBJECTIVES:The aim of this study was to understand the barriers and facilitators to providing high-quality continuum of care for veterans transitioning from non-VA hospitals to the VA primary care setting. DESIGN:Guided by the practical robust implementation and sustainability model (PRISM) and the ideal transitions of care, we conducted a qualitative assessment using semi-structured interviews with clinicians, staff, and patients. SETTING:This study was conducted at a single urban VA medical center and two non-VA hospitals. PARTICIPANTS:A total of 70 participants, including 52 clinicians and staff (23 VA and 29 non-VA) involved in patient transition and 18 veterans recently discharged from non-VA hospitals, were included in this study. APPROACH:Data were analyzed using a conventional content analysis and managed in Atlas.ti (Berlin, Germany). RESULTS:Four major themes emerged where participants consistently discussed that transitions were delayed when they were not able to (1) identify patients as veterans and notify VA primary care of discharge, (2) transfer non-VA hospital medical records to VA primary care, (3) obtain follow-up care appointments with VA primary care, and (4) write VA formulary medications for veterans that they could fill at VA pharmacies. Participants also discussed factors involved in smooth transition and recommendations to improve care coordination. CONCLUSIONS:All participants perceived the current transition-of-care process across healthcare systems to be inefficient. Efforts to improve quality and safety in transitional care should address the challenges clinicians and patients experience when transitioning from non-VA hospitals to VA primary care.

Project description:BackgroundLearner satisfaction assessment is critical in the design and improvement of training programs. However, little is known about what influences satisfaction and whether trainee specialty is correlated. A national comparison of satisfaction among internal medicine subspecialty fellows in the Department of Veterans Affairs (VA) provides a unique opportunity to examine educational factors associated with learner satisfaction. We compared satisfaction across internal medicine fellows by subspecialty and compared factors associated with satisfaction between procedural versus non-procedural subspecialty fellows, using data from the Learners' Perceptions Survey (LPS), a validated survey tool.MethodsWe surveyed 2,221 internal medicine subspecialty fellows rotating through VA between 2001 and 2008. Learners rated their overall training satisfaction on a 100-point scale, and on a five-point Likert scale ranked satisfaction with items within six educational domains: learning, clinical, working and physical environments; personal experience; and clinical faculty/preceptor.ResultsProcedural and non-procedural fellows reported similar overall satisfaction scores (81.2 and 81.6). Non-procedural fellows reported higher satisfaction with 79 of 81 items within the 6 domains and with the domain of physical environment (4.06 vs. 3.85, p <0.001). Satisfaction with clinical faculty/preceptor and personal experience had the strongest impact on overall satisfaction for both. Procedural fellows reported lower satisfaction with physical environment.ConclusionsInternal medicine fellows are highly satisfied with their VA training. Nonprocedural fellows reported higher satisfaction with most items. For both procedural and non-procedural fellows, clinical faculty/preceptor and personal experience have the strongest impact on overall satisfaction.

Project description:Comparing hospital performance in a health system is traditionally done with multilevel regression models that adjust for differences in hospitals' patient case-mix. In contrast, "template matching" compares outcomes of similar patients at different hospitals but has been used only in limited patient settings.Our objective was to test a basic template matching approach in the nationwide Veterans Affairs healthcare system (VA), compared with a more standard regression approach.We performed various simulations using observational data from VA electronic health records whereby we randomly assigned patients to "pseudo hospitals," eliminating true hospital level effects. We randomly selected a representative template of 240 patients and matched 240 patients on demographic and physiological factors from each pseudo hospital to the template. We varied hospital performance for different simulations such that some pseudo hospitals negatively impacted patient mortality.Electronic health record data of 460,213 hospitalizations at 111 VA hospitals across the United States in 2015.We assessed 30-day mortality at each pseudo hospital and identified lowest quintile hospitals by template matching and regression. The regression model adjusted for predicted 30-day mortality (as a measure of illness severity).Regression identified the lowest quintile hospitals with 100% accuracy compared with 80.3% to 82.0% for template matching when systematic differences in 30-day mortality existed.The current standard practice of risk-adjusted regression incorporating patient-level illness severity was better able to identify lower-performing hospitals than the simplistic template matching algorithm.

Project description:BackgroundPrimary care providers (PCPs) vary in skills to effectively treat depression. Key features of evidence-based collaborative care models (CCMs) include the availability of depression care managers (DCMs) and mental health specialists (MHSs) in primary care. Little is known, however, about the relationships between PCP characteristics, CCM features, and PCP depression care.ObjectiveTo assess relationships between various CCM features, PCP characteristics, and PCP depression management.DesignCross-sectional analysis of a provider survey.Participants180 PCPs in eight VA sites nationwide.Main measuresIndependent variables included scales measuring comfort and difficulty with depression care; collaboration with a MHS; self-reported depression caseload; availability of a collocated MHS, and co-management with a DCM or MHS. Covariates included provider type and gender. For outcomes, we assessed PCP self-reported performance of key depression management behaviors in primary care in the past 6 months.Key resultsResponse rate was 52 % overall, with 47 % attending physicians, 34 % residents, and 19 % nurse practitioners and physician assistants. Half (52 %) reported greater than eight veterans with depression in their panels and a MHS collocated in primary care (50 %). Seven of the eight clinics had a DCM. In multivariable analysis, significant predictors for PCP depression management included comfort, difficulty, co-management with MHSs and numbers of veterans with depression in their panels.ConclusionsPCPs who felt greater ease and comfort in managing depression, co-managed with MHSs, and reported higher depression caseloads, were more likely to report performing depression management behaviors. Neither a collocated MHS, collaborating with a MHS, nor co-managing with a DCM independently predicted PCP depression management. Because the success of collaborative care for depression depends on the ability and willingness of PCPs to engage in managing depression themselves, along with other providers, more research is necessary to understand how to engage PCPs in depression management.

Project description:BackgroundStakeholder engagement helps ensure that research is relevant, clinical innovations are responsive, and healthcare services are patient-centered.ObjectiveEstablish and sustain a Veteran engagement board involving older Veterans and caregivers to provide input on aging-related research and clinical demonstration projects.Design and participantsThe Older Veteran Engagement Team (OVET)-a group of eight Veterans and one caregiver who range in age from 62 to 92-was formed in November 2017 and has met monthly since January 2018. The OVET provides feedback on topics that reflect the foci of the VA Eastern Colorado Geriatric Research Education and Clinical Center (GRECC) (e.g., physical functioning, hearing health, and emotional wellness/mental health). Ongoing evaluation documents the return on investment of Veteran engagement.Main measuresThe OVET member and provider/investigator meeting evaluations with longitudinal follow-up at 6 and 12 months.ResultsReturn on investment of Veteran engagement is multi-faceted. For OVET, ROI ranges from grant support to improved healthcare quality/efficiency to social-emotional benefits. To date, funding awards total over $2.3 M for NIH and VA-funded projects to which OVET provided substantive feedback. Documented impacts on healthcare services include reductions in patient wait times, more appropriate utilization of services and increased patient satisfaction. Social-emotional benefits include generativity, as OVET members contribute to improving clinical and community-based supports for other Veterans. The OVET provides an opportunity for older Veterans to share their lived experience with trainees and early career investigators who are preparing for careers serving Veterans.ConclusionThe OVET is similar to other established stakeholder engagement groups; team members offer their individual viewpoints at any stage of research, clinical demonstration, or quality improvement projects. The OVET provides a mechanism for the voice of older Veterans and caregivers to shape aspects of individual projects. Importantly, these projects support patient-centered care and promote the characteristics of an age-friendly healthcare system.

Project description:Although women will account for almost 11% of veterans by 2040, we know little about their health and functioning, particularly compared to men.To compare women and men veterans' health-related quality of life (HRQOL) and VA health care utilization and to see if previously described associations between HRQOL, subsequent VA health care utilization, and mortality in male veterans would generalize to women veterans.Prospective cohort study of all veterans who received medical care from an Upper Midwest Veterans Affairs facility between 10/1/96 and 3/31/98 and returned a mailed questionnaire.Women's effective survey response rate was 52% (n = 1,500); men's, 58% (n = 35,000). In the following year, 9% of women and 12% of men had at least one hospitalization. One percent of women and 3% of men died in the post-survey year. After adjustment, women's HRQOL was higher than men's; for every 10-point decrement in overall physical or mental functioning, women and men had similarly increased risk/odds of subsequently dying, being hospitalized at a VA facility, or making a VA outpatient stop. Among younger women and women who received VA care outside of the Twin City metro area, poorer overall mental or physical health functioning was associated with fewer primary care stops; among their male counterparts, it was associated with more primary care stops.Compared to men, women veterans receiving VA health care in the upper Midwest catchment area had better HRQOL and used fewer health services. Although VA health care utilization was similar across gender after adjusting for HRQOL, poorer mental or physical health was associated with fewer primary care stops for selected subgroups of women.
