Medicare treatment differences for blacks and whites

Area of Science:

• Health Services Research
• Racial Disparities in Healthcare
• Medicare Beneficiary Outcomes

Background:

• Investigated potential racial differences in healthcare utilization among elderly Medicare beneficiaries.
• Examined whether observed disparities in treatment between Black and White patients are due to factors beyond race, such as access or regional practices.

Purpose of the Study:

• To investigate racial differences in the utilization of selected medical procedures among elderly Medicare beneficiaries.
• To test the hypothesis that observed treatment differences between Black and White patients are attributable to factors other than inappropriate provider discrimination.

Main Methods:

• Analyzed Medicare utilization data for beneficiaries across 10 states and the District of Columbia.
• Employed zip code-based matching to control for differences in provider access and regional practice patterns between Black and White patients.
• Considered the impact of standardized Medicare benefits on financial access disparities.

Main Results:

• Area-controlled comparisons revealed even greater racial disparities in procedure use than uncontrolled comparisons.
• These disparities were more pronounced in Southern states.
• Utilization differences varied significantly based on the cost of the medical procedure.

Conclusions:

• Despite controlling for various factors, providers appeared to offer less intensive treatment to Black Medicare beneficiaries compared to otherwise similar White beneficiaries.
• The findings suggest potential racial bias in treatment intensity, even when controlling for access and practice patterns.
