Patients hospitalized for medical conditions in Winnipeg, Canada: appropriateness and level of care.

A medical record review of patients hospitalized for medical conditions in Winnipeg, Canada during 1998/99 was completed using InterQual utilization review instruments. On admission, 95% of patients required the services provided in an acute care facility. Fifty-eight percent of days in hospital following the day of admission required an acute care setting, and 42% required an alternate level of care. Our results suggest there is room for treating more acute patients within the existing system.
