Why the study?
The effects of patient insurance status and hospital safety-net status on readmission rates following acute myocardial infarction are unclear.
Do patient insurance status and hospital safety-net status affect readmission rates following acute myocardial infarction?
Do patient insurance status and hospital safety-net status affect readmission rates following acute myocardial infarction?
Medicaid insurance and treatment at high-burden safety-net hospitals are associated with significantly increased odds of 30- and 90-day readmission following acute myocardial infarction.
Medicaid status was associated with higher post-MI readmissions; hypothesis-generating for insurance and safety-net effects, should not yet change practice.
Background: Low socioeconomic status predicts inferior clinical outcomes in many patient populations. The effects of patient insurance status and hospital safety-net status on readmission rates following acute myocardial infarction are unclear. Materials & methods: A retrospective review of State Inpatient Databases for New York, California, Florida and Maryland, 2007–2014. Results: A total of 1,055,162 patients were included. Medicaid status was associated with 37.7 and 44.0% increases in risk-adjusted readmission odds at 30 and 90 days (p < 0.0001). Uninsured status was associated with reduced odds of readmission at both time points. High-burden safety-net status was associated with 9.6 and 9.5% increased odds of readmission at 30 and 90 days (p < 0.0003). Conclusion: Insurance status and hospital safety-net burden affect readmission odds following acute myocardial infarction.
