Do Hospitalizations Disrupt Loyalty to Ambulatory Care Providers?

We sought to determine whether hospitalizations affect where patients seek ambulatory care. We conducted a retrospective cohort study of 569 adults who were attributed by a commercial payer to a large physician organization (PO) and hospitalized in 2015. Approximately half of the patients (55%) were admitted to the hospital affiliated with the PO; the rest were hospitalized elsewhere. Patients hospitalized elsewhere were significantly less likely to be seen by a PO provider in the 6 months posthospitalization than those hospitalized at the affiliated hospital (adjusted odds ratio = 0.29; 95% confidence interval = 0.17-0.48). These results have important implications for population management.
