Comparing Quality in Medicare FFS and Medicare Advantage Mark Shepard Harvard University Heritage Foundation Briefing June 28, 2011
Context for MA-FFS Comparison • Mandate in MIPPA to compare quality in MA and FFS starting this year. • Quality comparisons are a potential tool for beneficiaries making enrollment choices. • Build on quality comparisons among plans when select MA plan on Medicare Plan Finder website. • Little previous work comparing the programs on quality of care because of data availability. • Goal: Compare MA and FFS nationally using identical measures, constructed as similarly as possible.
Data and Methods • MA: HEDIS data publicly reported for 2006-07, pooled to form national quality rate • Exclude PFFS plans due to data availability • FFS: National measures for 2006-07 calculated from Medicare claims by CMS (GEM project) • Based on administrative HEDIS specifications • Statistically adjust for different geographic distribution of MA and FFS beneficiaries
Quality Measures • 11 HEDIS measures of appropriate preventive screenings and medication management
Interpreting MA-FFS Differences FFS Higher/Close (3) MA Higher Quality (8) • All newer in HEDIS: introduced 2004-2005 • Improved rapidly in MA from 2006 to 2007; also in 2008-2009 • All “well-established” in HEDIS: since 1990s • Declined in quality in MA from 2006 to 2007 • Suggested Explanation: MA “Learning Effect”
Older and Newer Measures in MA Averages calculated from NCQA, State of Health Care Quality, 2010
Limitations of MA-FFS Comparison • Population Differences • Beneficiaries who choose MA may be easier/ harder to deliver appropriate care. • Measurement Differences • FFS has only claims data, while MA plans can also use chart review (hybrid measures). • Additional research needed to address these limitations.
Conclusions • MA better on 9 of 11measures • Much better on 8 measures, slightly better or worse than FFS on 3 measures • MA performed best on older HEDIS measures, worst on the newer measures. • Suggested explanation: MA plan learning effect • Substantial differences in absolute terms, but even larger variation across MA plans
