Association between hospital ownership type and ST-segment elevation myocardial infarction outcomes: Insights from the National Readmission Database, 2016-2022
- retrospective cohort study
Authors' conclusion
For-profit and public hospitals were associated with higher in-hospital mortality and 90-day readmission for various causes compared with nonprofit hospitals. These findings suggest that hospital-level factors may contribute to disparities in STEMI outcomes and warrant further investigation.
