To determine whether the rate of rehospitalization is lower among patients discharged to skilled nursing facilities (s) with which a hospital has a strong linkage.
We used national Medicare enrollment, claims, and the Minimum Data Set to examine 2.8 million newly discharged patients to 15,063 s from 2,477 general hospitals between 2004 and 2006.
We examined the relationship between the proportion of discharges from a hospital and alternative s on the rehospitalization of patients treated by that hospital– pair using an instrumental variable approach. We used distances to alternative s from residence of the patients of the originating hospital as the instrument.
Our estimates suggest that if the proportion of a hospital's discharges to an was to increase by 10 percentage points, the likelihood of patients treated by that hospital– pair to be rehospitalized within 30 days would decline by 1.2 percentage points, largely driven by fewer rehospitalizations within a week of hospital discharge.
Stronger hospital– linkages, independent of hospital ownership, were found to reduce rehospitalization rates. As hospitals are held accountable for patients' outcomes postdischarge under the Affordable Care Act, hospitals may steer their patients preferentially to fewer s.
