Patient outcomes and length of stay in a stroke unit offering both acute and rehabilitation services.

OBJECTIVES To compare hospital length of stay (LOS) and outcome after stroke between patients in a stroke unit offering combined acute and rehabilitation services and patients treated elsewhere in New South Wales. DESIGN Retrospective audit of two hospital databases (Diagnosis-Related Groups [DRG] database and Australian National Subacute Non-Acute Patient Classification System [AN-SNAP] database), with comparison with DRG and AN-SNAP data for NSW. SETTING AND PARTICIPANTS 242 episodes of acute stroke in patients admitted to the stroke unit of a metropolitan teaching hospital between July 1999 and November 2000, 113 of whom also underwent rehabilitation in the unit; 9777 episodes of acute stroke in the NSW DRG database, and 2350 in the NSW AN-SNAP database. MAIN OUTCOME MEASURES Acute and rehabilitation LOS; mortality in acute care; FIM (Functional Independence Measure) score at discharge and change in FIM score; and discharge destination. RESULTS Patients in the combined stroke unit had shorter LOS and better functional outcome in all DRG and AN-SNAP groups, with both higher discharge FIM scores and greater gain in FIM scores than NSW patients. Acute stroke mortality of 12% and nursing home admission rate of 15.5% in the combined stroke unit were not significantly different from rates for NSW (15.7% and 11.2%, respectively). CONCLUSIONS Combining acute and rehabilitation services in a stroke unit may reduce LOS and improve functional outcome of patients with acute stroke.
