Critically ill medical patients, their demographics and outcome.

There are few reports describing the demographic details and outcome of noncoronary medical patients on adult general intensive care units. It is not known how medical patients differ from other critically ill patients and how this may influence their outcome. Consequently, we recorded the demographic details of 374 critically ill medical patients and followed their survival for up to 3 years. Patients referred from medical specialties are younger, more severely ill and suffer a higher severity-of-illness-adjusted intensive care unit mortality than other patients. The short-term survival of medical patients is poor with a median survival of 40 days. Twenty per cent of medical patients die after discharge from intensive care but before 40 days. However, the long-term survival of medical patients is better than other patients and almost as good as the general population. Further research is required to identify those patients who are likely to survive beyond 40 days.
