People with mental illnesses (MI) receive suboptimal care for medical comorbidities and their high risk for readmission may be addressed by adequate medication management and follow-up care. We examined the association between MI, medication changes, and post-discharge outpatient visits with 30-day readmission in 40,048 Medicare beneficiaries hospitalized for acute myocardial infarction, heart failure or pneumonia. Beneficiaries with MI were more likely to be readmitted than those without MI (14 vs. 11%). Probability of readmission was 13 and 12% when medications were dropped or added, respectively, versus 11% when no change was made. Probability of readmission also increased with outpatient visits.
