Organised inpatient (stroke unit) care for stroke

Background Organised stroke unit care is provided by multidisciplinary teams that exclusively manage stroke patients in a dedicated ward ( stroke, acute, rehabilitation, comprehensive), with a mobile stroke team or within a generic disability service ( mixed rehabilitation ward). Objectives To assess the effect of stroke unit care compared with alternative forms of care for patients following a stroke. Search stategy We searched the Cochrane Stroke Group trials register ( last searched April 2006), the reference lists of relevant articles, and contacted researchers in the field. Selection criteria Randomised and prospective controlled clinical trials comparing organised inpatient stroke unit care with an alternative service. Data collection and analysis Two review authors initially assessed eligibility and trial quality. Descriptive details and trial data were then checked with the coordinators of the original trials. Main results Thirty-one trials, involving 6936 participants, compared stroke unit carewith an alternative service; more organised carewas consistently associated with improved outcomes. Twenty-six trials ( 5592 participants) compared stroke unit care with general wards. Stroke unit care showed reductions in the odds of death recorded at final ( median one year) follow up ( odds ratio ( OR) 0.86; 95% confidence interval ( CI) 0.76 to 0.98; P = 0.02), the odds of death or institutionalised care ( OR 0.82; 95% CI 0.73 to 0.92; P = 0.0006) and death or dependency ( OR 0.82; 95% CI 0.73 to 0.92; P = 0.001). Sensitivity analyses indicated that the observed benefits remained when the analysis was restricted to trials that used formal randomisation procedures with blinded outcome assessment. Outcomes were independent of patient age, sex or stroke severity, but appeared to be better in stroke units based in a discrete ward. There was no indication that organised stroke unit care resulted in a longer hospital stay. Authors' conclusions Stroke patients who receive organised inpatient care in a stroke unit are more likely to be alive, independent, and living at home one year after the stroke. The benefits were most apparent in units based in a discrete ward. No systematic increase was observed in the length of inpatient stay.
