Alcohol use and hospital readmissions following stroke: A safety net hospital experience

Abstract

ObjectiveThe purpose of this study is to identify predictors of stroke-related readmissions at 30days on a safety net hospital level and suggest interventions to reduce the number of readmissions. BackgroundHospital readmissions are an important measure of the quality of health care services. Readmissions indicate unresolved problems from the index admission, inadequate post-hospitalization care, or a mixture of these factors. Additionally, hospital readmissions are associated with a substantial economic burden on the health care system. The study's purpose is to identify predictors of stroke-related readmissions within 30days on a hospital level and suggest interventions to reduce the number of readmissions. MethodsWe conducted a single-center retrospective study of patients admitted to Boston Medical Center (BMC) and diagnosed with ischemic and hemorrhagic stroke. Unadjusted and adjusted logistic regressions were used to evaluate possible predictors of stroke related readmissions. ResultsOf 352 patients admitted with a diagnosis of ischemic or hemorrhagic stroke at BMC during the study period, 44 (12.5%) patients were readmitted to BMC within 30days. Current alcohol abuse was significantly associated with readmission (OR 95% CI 1.03–5.62). Discharge against medical advice was also associated, though the sample size was small. ConclusionsThese results suggest that early inpatient and post-hospitalization interventions to address alcohol abuse during the index hospital admission may reduce the rate of hospital readmission within 30days. The results have prompted interventions on the stroke service such as early inpatient social work and addiction medicine involvement for patients with risk factors of alcohol abuse.
