Differences In Use Of Services And Quality Of Care In Medicare Advantage And Traditional Medicare, 2010 And 2017

Area of Science:

• Health Services Research
• Comparative Effectiveness Research
• Health Policy Analysis

Background:

• Medicare Advantage (MA) enrollment is growing, raising questions about its ability to maintain quality and control utilization compared to traditional Medicare.
• Previous studies suggest MA plans may offer advantages in cost and quality, but evidence needs continuous updating with evolving enrollment patterns.

Purpose of the Study:

• To compare the quality of care and healthcare utilization between Medicare Advantage (MA) plans and traditional Medicare (TM) in 2010 and 2017.
• To assess if increasing MA enrollment impacts its ability to deliver high-quality care and manage utilization effectively.

Main Methods:

• Comparative analysis of clinical quality measures, patient-reported outcomes, and utilization data (emergency department visits, elective surgeries) between MA (HMOs and PPOs) and TM beneficiaries.
• Utilized data from 2010 and 2017 to observe trends and differences over time.

Main Results:

• MA Health Maintenance Organizations (HMOs) and Preferred Provider Organizations (PPOs) demonstrated higher clinical quality performance than TM across most measures in both 2010 and 2017.
• MA HMOs outperformed TM on all quality measures in 2017, with significant improvements in patient-reported outcomes.
• MA plans exhibited lower utilization rates, including 30% fewer emergency department visits and nearly 30% fewer back surgeries in MA HMOs compared to TM in 2017.

Conclusions:

• Medicare Advantage plans consistently demonstrate equal or superior quality performance compared to traditional Medicare.
• Despite significant enrollment growth, MA plans effectively manage healthcare utilization, showing lower rates for key services.
• MA plans represent a viable, high-quality alternative to traditional Medicare, even with expanding enrollment.
