Post-hospital home health care for Medicare patients.

Medicare patients in five diagnosis-related groups (DRGs) associated with heavy use of post-hospital care discharged from 52 hospitals in 3 cities were followed up at 6 weeks, 6 months, and 1 year to determine the factors associated with their being discharged home with or without home health care and the correlates of improvement in their functional status. Models correctly predicted those discharged home from those going to institutions in a range from 54 to 82 percent of cases. The amount of the variance in the change in function for those who went home (with or without home health care) explained by the models tested ranged from 19 percent to 73 percent. Total Medicare costs for the patients who went home were considerably less in the year subsequent to the hospitalization compared with those discharged to institutional care.
