Item The association between socioeconomic status and disability after stroke: Findings from the Adherence eValuation After Ischemic stroke Longitudinal (AVAIL) registry(2014-03) Bettger, Janet Prvu; Zhao, Xin; Bushnell, Cheryl; Zimmer, Louise; Pan, Wenqin; Williams, Linda S.; Peterson, Eric DBackground Stroke is the leading cause of disability among adults in the United States. The association of patients’ pre-event socioeconomic status (SES) with post-stroke disability is not well understood. We examined the association of three indicators of SES—educational attainment, working status, and perceived adequacy of household income—with disability 3-months following an acute ischemic stroke. Methods We conducted retrospective analyses of a prospective cohort of 1965 ischemic stroke patients who survived to 3 months in the Adherence eValuation After Ischemic stroke – Longitudinal (AVAIL) study. Multivariable logistic regression was used to examine the relationship of level of education, pre-stroke work status, and perceived adequacy of household income with disability (defined as a modified Rankin Scale of 3–5 indicating activities of daily living limitations or constant care required). Results Overall, 58% of AVAIL stroke patients had a high school or less education, 61% were not working, and 27% perceived their household income as inadequate prior to their stroke. Thirty five percent of patients were disabled at 3-months. After adjusting for demographic and clinical factors, stroke survivors who were unemployed or homemakers, disabled and not-working, retired, less educated, or reported to have inadequate income prior to their stroke had a significantly higher odds of post-stroke disability. Conclusions In this cohort of stroke survivors, socioeconomic status was associated with disability following acute ischemic stroke. The results may have implications for public health and health service interventions targeting stroke survivors at risk of poor outcomes.Item Persistence With Stroke Prevention Medications 3 Months After Hospitalization(American Medical Association, 2010) Bushnell, Cheryl D.; Zimmer, Louise O.; Pan, Wenqin; Olson, Daiwai M.; Zhao, Xin; Meteleva, Tatiana; Schwamm, Lee; Ovbiagele, Bruce; Williams, Linda; Labresh, Kenneth A.; Peterson, Eric D.; Adherence Evaluation After Ischemic Stroke–Longitudinal Investigators; Neurology, School of MedicineObjective: To measure longitudinal use of stroke prevention medications following stroke hospital discharge. We hypothesized that a combination of patient-, provider-, and system-level factors influence medication-taking behavior. Design: Observational cohort design. Setting: One hundred six US hospitals participating in the American Heart Association Get With The Guidelines-Stroke program. Patients: Two thousand eight hundred eighty-eight patients 18 years or older admitted with ischemic stroke or transient ischemic attack. Main outcome measure: Regimen persistence, including use of antiplatelet therapies, warfarin, antihypertensive therapies, lipid-lowering therapies, or diabetes medications, from discharge to 3 months. Reasons for nonpersistence were also ascertained. Results: Two thousand five hundred ninety-eight patients (90.0%) were eligible for analysis. At 3 months, 75.5% of subjects continued taking all secondary prevention medications prescribed at discharge. Persistence at 3 months was associated with decreasing number of medication classes prescribed, increasing age, medical history, less severe stroke disability, having insurance, working status, understanding why medications are prescribed and how to refill them, increased quality of life, financial hardship, geographic region, and hospital size. Conclusions: One-quarter of stroke patients reported discontinuing 1 or more of their prescribed regimen of secondary prevention medications within 3 months of hospitalization for an acute stroke. Several modifiable factors associated with regimen persistence were identified and could be targets for improving long-term secondary stroke prevention.
