Hospital partnership and patient outcomes among postacute patients with stroke.

Abstract

OBJECTIVES:

Postacute care (PAC) heavily relies on effective connection between acute and postacute providers. However, little is known about whether and to what extent providers' patient-sharing relationships influence patient outcomes. This study aimed to examine whether patients with stroke who were discharged to PAC hospitals with which the originating hospital had a strong patient-sharing relationship have a lower rate of rehospitalization and lower mortality risk.

STUDY DESIGN:

This population-based retrospective cohort study used the Taiwan National Health Insurance Research Database. A total of 1988 patients initially hospitalized for stroke between July 1, 2017, and June 30, 2018, who were newly discharged to 193 PAC hospitals from 175 originating hospitals were included.

METHODS:

We described the partnership between originating acute hospitals and PAC hospitals using tie strength and referral concentration. The main outcome included unplanned readmission and mortality. Hierarchical logistic regression analysis and Cox proportional hazards models were applied.

RESULTS:

A dose-response relationship was clearly observed between tie strength and patient outcomes. Patients with stroke who were discharged to a PAC hospital that had the strongest tie strength with the originating hospital were least likely to be readmitted and had the lowest mortality risk. Moreover, patients who received care from hospital pairs with highly or moderately concentrated referrals also had lower readmission and mortality risk.

CONCLUSIONS:

A greater number of shared patients and a more concentrated referral linkage between acute and PAC providers may reduce potential adverse outcomes in PAC patients. Instead of attaining more partners, PAC policies should encourage providers to strengthen their patient-sharing relationship with their existing PAC partners.
