Background:In-hospital stroke (IHS) represents 5–15% of all hospitalized acute stroke cases, and is associated with poor outcomes. IHS represents an important area for prevention since many cases occur in high-risk patients undergoing cardiovascular procedures. Our objectives were to compare the quality of care, treatments, and outcomes of IHS with out-of-hospital stroke (OHS) cases. Methods: A 6-month prospective cohort of IHS and OHS stroke cases from a statewide acute stroke registry of 15 representative hospitals was assembled. Data were abstracted on demographic, clinical characteristics, in-hospital care (including tPA treatment), discharge instructions, and in-hospital outcomes (mortality and modified Rankin Scale [mRS] at discharge). Results:177 (6.5%) of the 2,743 cases in the registry were IHS cases. 40% of IHS cases were admitted with a cardiovascular or neurologically related problem, and 68% underwent an invasive diagnostic or surgical procedure prior to their stroke. IHS cases were less likely to have the cerebral vasculature examined or to have a lipid panel drawn. Compared to OHS, IHS had higher case fatality (14.6 vs. 6.9%; p = 0.04), greater functional impairment (mRS ≧4) (61 vs. 36%; p < 0.001), and were less likely to be discharged home (23 vs. 52%, p < 0.01). Conclusions:In this prospective registry, 1 in 15 acute stroke cases occurred in the hospital, and almost 70% had an invasive procedure undertaken prior to their stroke event. In-hospital cases received similar quality of care as OHS cases, but had significantly worse outcomes.
