People with serious mental illness (SMI)—for example, schizophrenia, bipolar disorder, and major depression—experience pronounced challenges in psychological and social functioning that often co-occur with physical health conditions. They receive inferior quality of medical care compared with patients without SMI.1 Risk-adjusted 30-day readmissions are an important indicator of quality care used by the Centers for Medicare & Medicaid Services to guide pay for performance.2 Research using hospital and state data suggests that medical and surgical readmission rates for patients with SMI may be higher than for those without SMI, but the differences in nationwide estimates of 30-day all-cause readmissions are unknown.3-5 The objective of our study was to compare nationwide medical and surgical readmission rates in patients with and without SMI.
