Post-acute service use following acute myocardial infarction in elderly Medicare patients

This exploratory study examined the extent to which factors beyond characteristics of the patient, such as discharging hospital attributes and State factors, contributed to variations in post-acute services use (PASU) in a cohort of elderly Medicare patients following acute myocardial infarction (AMI). Thirty-seven percent of this cohort received PAS within 30 days of discharge and home health care was the most common type of service used. Patient severity of illness at hospital discharge, for-profit ownership of the discharging hospital, and discharging hospital provision of home health services were shown to be important predictors of PASU. After adjusting for many patient and hospital characteristics, however, variation in PASU remained across States. (January 2002)
