Underuse of invasive procedures among Medicaid patients with acute myocardial infarction

Area of Science:

• Cardiology
• Health Services Research
• Health Economics

Background:

• Access to cardiac procedures can be influenced by insurance status.
• Disparities in healthcare utilization exist among different patient populations.
• Acute myocardial infarction (AMI) necessitates timely and appropriate cardiac interventions.

Purpose of the Study:

• To investigate if underuse of cardiac procedures in acute myocardial infarction (AMI) patients with Medicaid insurance is due to patient characteristics or other factors.
• To compare cardiac procedure utilization between Medicaid patients and those with other insurance types.

Main Methods:

• Analysis of administrative data from 226 New York hospitals.
• Inclusion of 11,579 individuals hospitalized with acute myocardial infarction (AMI).
• Comparison of cardiac procedure use (cardiac catheterization, percutaneous transluminal coronary angioplasty, revascularization) between Medicaid and non-Medicaid patients, adjusting for covariates.

Main Results:

• Medicaid patients were older, more often African American and female, and had lower incomes.
• Medicaid patients exhibited higher rates of comorbidities including hypertension, diabetes, lung disease, renal disease, and peripheral vascular disease.
• Even after adjusting for demographic, socioeconomic, and clinical factors, Medicaid patients were less likely to undergo cardiac catheterization, percutaneous transluminal coronary angioplasty, and revascularization.

Conclusions:

• Factors beyond age, race, sex, income, comorbidities, and care location contribute to the lower utilization of invasive cardiac procedures among Medicaid patients.
• The impact of Medicaid insurance on medical practice and the quality of care warrants further investigation.
• Addressing disparities in cardiac procedure use for AMI patients is crucial for equitable healthcare outcomes.
