What regional differences exist in 30-day acute MI hospital mortality and readmission rates for Medicare beneficiaries 65 years of age?
In the United States, important regional differences exist in 30-day acute MI hospital mortality and readmission rates for Medicare beneficiaries 65 years of age. For example, according to a study published in Circulation in 2019, 30-day acute MI hospital mortality rates ranged from 5.3% to 16.4%, and 30-day readmission rates ranged from 11.9% to 27.4% across the United States. Furthermore, patients treated in hospitals with higher volumes of acute MI patients had lower mortality and readmission rates. Understanding the reasons for such differences may provide opportunities for performance improvement.
