CRITICAL CARE Long-term functional outcome and performance status after intensive care unit re-admission: a prospective survey

Methods. With ethical committee approval, from a prospectively collected database of all admissions to a combined medical and surgical ICU from January 1 to December 31, 2004, we identified all ICU re-admissions from within the hospital and analysed the factors associated with increased incidence of re-admission. At 2–3 yr after discharge, we evaluated the functional outcome of the surviving re-admitted patients as Glasgow Outcome Score (GOS) and Karnofsky index and identified determinants of both mortality and good functional outcome.
