Background/Objectives:
Previous research indicates that eligibility criteria for medication therapy management (MTM) services in Medicare prescription drug (Part D) plans, defined under the Medicare Modernization Act (MMA), are associated with racial/ethnic disparities and ineffective in identifying individuals with medication utilization issues. Our study's objective was to determine the comparative effectiveness of MTM eligibility criteria under MMA and in the Affordable Care Act (ACA) in identifying patients with medication utilization issues across racial/ethnic groups.
Design:
ACA and MMA MTM eligibility criteria were compared on proportions of eligible individuals among patients with medication utilization issues. Multinomial logistic regression was conducted to control for patient/community characteristics. Need-based and demand-based analyses were used to determine disparities due to need and demand for healthcare. Main/sensitivity analyses were conducted for the range of eligibility thresholds.
Setting:
Medicare data (2012-2013) linked to Area Health Resources Files.
Participants:
A total of 964 610 patients 65 years or older.
Measurements:
Medication safety/adherence measures, developed primarily by the Pharmacy Quality Alliance, were used to determine medication utilization issues.
Results:
Higher proportions of patients were eligible based on ACA than MMA MTM eligibility criteria. For example, in 2013, proportions based on ACA and MMA MTM eligibility criteria would be 99.7% and 26.2%, respectively, in the main analysis (p < .001); in the demand-based main analysis, ACA criteria were associated with 13.6% and 9.8%, respectively, higher effectiveness than MMA criteria among non-Hispanic blacks and Hispanics than non-Hispanic whites.
Conclusion:
ACA MTM eligibility criteria are more effective than MMA criteria in identifying older patients needing MTM, particularly among minorities. J Am Geriatr Soc 67:581-587, 2019.
Insights
The Affordable Care Act (ACA) criteria for medication therapy management (MTM) better identify older adults needing care than Medicare Modernization Act (MMA) criteria. ACA MTM identifies more minority patients with medication issues.
Area of Science:
- Gerontology
- Health Services Research
- Health Disparities
Background:
- Previous research indicates Medicare Modernization Act (MMA) criteria for medication therapy management (MTM) services are racially/ethnically biased and ineffective.
- These criteria fail to identify patients with significant medication utilization issues.
Purpose of the Study:
- To compare the effectiveness of MTM eligibility criteria under the Affordable Care Act (ACA) versus the MMA.
- To determine how these criteria identify patients with medication utilization issues across different racial/ethnic groups.
Main Methods:
- Compared ACA and MMA MTM eligibility criteria using Medicare data (2012-2013).
- Utilized medication safety/adherence measures to define medication utilization issues.
- Employed multinomial logistic regression and need/demand-based analyses to assess disparities.
Main Results:
- ACA MTM eligibility criteria identified a higher proportion of patients needing MTM compared to MMA criteria.
- In 2013, ACA criteria would make 99.7% of patients eligible versus 26.2% for MMA criteria (p < .001).
- Demand-based analysis showed ACA criteria were more effective in identifying MTM needs among Black and Hispanic patients compared to non-Hispanic Whites.
Conclusions:
- ACA MTM eligibility criteria are more effective than MMA criteria for identifying older patients requiring MTM.
- These ACA criteria show particular effectiveness in identifying needs among minority populations.
