Do nonprofit HMOs eliminate racial disparities in cardiac care?

Area of Science:

• Health Services Research
• Health Disparities
• Cardiovascular Disease Management

Background:

• Significant racial disparities exist in cardiovascular disease treatment access for African-Americans compared to white Americans.
• The sector difference theory proposes nonprofit managed care may mitigate these disparities.
• Understanding these differences is crucial for equitable healthcare delivery.

Purpose of the Study:

• To test the sector difference theory by comparing heart disease treatment access between for-profit and nonprofit Medicaid managed care plans.
• To determine if nonprofit Medicaid managed care plans reduce racial gaps in cardiovascular treatment.
• To analyze treatment disparities for African-Americans in different managed care sectors.

Main Methods:

• Utilized data from the Maryland Health Services Cost Review Commission for patients discharged in 1998.
• Included patients with circulatory system diseases (ICD-9-CM 390-459) or chest pain (ICD-9-CM 786.50-786.52, 786.59).
• Compared treatment utilization between for-profit and nonprofit Medicaid managed care programs, controlling for clinical factors.

Main Results:

• African-Americans were significantly less likely to receive key cardiovascular treatments.
• These disparities persisted even after controlling for principal diagnosis, blood pressure, comorbidities, and age.
• No significant differences in treatment access were found between for-profit and nonprofit Medicaid managed care sectors.

Conclusions:

• The sector difference theory was not supported in this analysis of Maryland Medicaid managed care plans.
• Nonprofit status of Medicaid managed care plans did not eliminate racial disparities in heart disease treatment access.
• Further research is needed to address persistent racial inequities in cardiovascular care.
