This study examines the relationship of hospital characteristics and a
ccess to postacute care (PAC) using a comprehensive database that comb
ines hospital characteristics with clinical and demographic informatio
n of patients. The data was drawn from 52 hospitals in three urban are
as-Minneapolis/St. Paul, Houston, and Pittsburgh-and 2,572 patients wi
thin five diagnosis-related groups (DRGs). The analysis found hospital
ownership of post-acute care significantly associated with use of PAC
for patients discharged after hospitalization for stroke and chronic
obstructive pulmonary disease (COPD). We found few significant hospita
l characteristics influencing use of PAC, but, as expected, for select
ed DRGs, patients were more likely to receive PAC if they were dischar
ged from a hospital that either owned post-acute care or sewed a high
proportion of Medicare patients. In general, patient characteristics w
ere more consistent predictors of post-acute care use across the DRGs
studied.
