Functional outcomes following medical intensive care

Abstract

This study describes the long-term functional outcomes of a medical and coronary care ICU population. Baseline and 1-yr follow-up data were collected prospectively from all 2213 patients admitted during a 2-yr period. Patients were stratified into three groups based on their preadmission functional status: active (n = 917), sedentary (n = 1017), or severely limited (n = 279). Those with severe functional limitation before admission were twice as likely to undergo major interventions (p less than .005). This group also had a significantly (p less than .001) higher mortality and incurred significantly (p less than .01) higher hospital charges than the other two groups, even though hospital lengths of stay were similar. Finally, cumulative mortality was significantly (p less than .001) greater for the severely limited patients: 33% expired in the ICU, 42% died while still in the hospital, and 63% died after discharge. Most survivors regained their preadmission functional status, with 60% of the previously employed returning to work. However, even for hospital survivors, mortality was high and was related to prior functional status: active 7%, sedentary 20%, severely impaired 37%.
