Poststroke rehabilitation in older Americans. The Medicare experience

This study examines the poststroke rehabilitation experience for a 20% sample of Medicare patients age 65 years and older admitted to an acute-care hospital with a stroke diagnosis during the 6-month interval, January 1, 1991 to June 30, 1991. Their Medicare claims data are used for two purposes: to identify current poststroke rehabilitation practice in the US population age 65 years and older, and to evaluate the importance of practice variation within this population.

Regarding the first objective, the authors develop estimates for many poststroke rehabilitation use and cost parameters that formerly were unmeasured. With respect to the second objective, the authors construct and compare average service use rates across all stroke patients in a census division and across all stroke patients residing in the 30 largest metropolitan statistical areas.

The authors' Medicare claims analysis indicates that 73% of stroke survivors received either postacute institutional or ambulatory rehabilitation care during the first 6 months poststroke. The published stroke literature, on the other hand, focuses on the minority of stroke survivors, 16.5% in the Medicare data, who were admitted to an inpatient rehabilitation hospital. Regarding the second study objective, the Medicare analysis provides graphic evidence that poststroke rehabilitation practice varies substantially from one geographic area to another and that practice differences translate into large geographic-related differences in the cost of poststroke rehabilitation.

The authors believe the findings demonstrate a problem with inconsistent poststroke rehabilitation practice.
