University of Michigan
MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Michigan was one of several states to expand Medicaid. Current evaluations of the Michigan Medicaid expansion program have noted increases in primary care services and health risk assessments, but less work has evaluated its role within a specialty service line. There has been concern among some that Medicaid patients, who have traditionally lacked access to preventive services, may be at high risk for poor clinical outcomes if provided increased access to cardiovascular interventions.
Using data from two physician-led quality collaboratives, we evaluated the volume and outcomes of percutaneous coronary interventions and coronary artery bypass grafting 24mos before and 24mos after expansion. We noted large-scale increased access to both percutaneous coronary interventions (44.5% increase) and coronary artery bypass grafting (103.8% increase) among patients with Medicaid insurance. There was a decrease in access for patients with private insurance in both cohorts. Nonetheless, outcomes (clinical and resource utilization) were not adversely impacted by expansion.
MedicalResearch.com: What should readers take away from your report?
Response: Expansion of Medicaid in the state of Michigan improved access to cardiovascular services without adversely impacting clinical outcomes.
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: Future work should focus on evaluating changes in 90-day episode expenditures associated with Medicaid expansion.
MedicalResearch.com: Is there anything else you would like to add?
