Abstract
BACKGROUND: [corrected] Few studies have examined associations among insurance status, treatment, and outcomes in patients hospitalized for intracerebral hemorrhage (ICH). METHODS: Through retrospective analyses of the Get With The Guidelines (GWTG)-Stroke database, a national prospective stroke registry, from April 2003 to April 2011, we identified 95,986 nontransferred subjects hospitalized with ICH. Insurance status was categorized as Private/Other, Medicaid, Medicare, or None/Not Documented (ND). Associations between insurance status and in-hospital outcomes and quality of care measures were analyzed using patient- and hospital-specific variables as covariates. RESULTS: There were significant differences in age and frequency of comorbid conditions by insurance group. Compliance with evidence-based quality of care indicators varied across all insurance status groups (P < .0001) but was generally high. In adjusted analysis with the Private insurance group as reference, the None/ND group most consistently demonstrated higher odds ratios (ORs) for quality of care measures (Dysphagia Screen: OR 1.10, 95% confidence interval [CI] 1.02-1.17, P = .0096; Stroke Education: OR 1.16, 95% CI 1.05-1.29, P = .0042; and Rehabilitation: OR 1.25, 95% CI 1.08-1.44, P = .0027). In-hospital mortality rates were higher for None/ND, Medicaid, and Medicare patients; after risk adjustment, the None/ND group had the highest mortality risk (OR 1.29, 95% CI 1.21-1.38, P < .0001). Medicare and Medicaid patients had lower adjusted odds for both independent ambulation at discharge and discharge to home when compared with the Private/Other group. CONCLUSIONS: GWTG-Stroke ICH patients demonstrated differences in mortality, functional status, discharge destination, and quality of care measures associated with insurance status.
