Positive Medication Changes Resulting from Comprehensive and Noncomprehensive Medication Reviews in a Medicare Part D Population

BACKGROUND: Health care organizations face the challenge of reducing costs while improving health outcomes. Currently, more than 39 million seniors are enrolled in a Medicare Part D prescription benefit plan, many of whom also qualify for medication therapy management (MTM) services. MTM programs provide valuable services designed to prevent or resolve medication-related problems (MRPs). Two core components of all MTM programs include comprehensive medication reviews (CMRs) with followup interventions and focused non-CMR interventions. Currently, there is limited research comparing the rate of MRPs resolved by CMR and non-CMR interventions. OBJECTIVE: To determine whether CMRs versus non-CMR interventions resulted in more pharmacist-initiated intervention recommendations and positive medication changes. METHODS: This retrospective, cross-sectional quality improvement project evaluated outcomes for individuals who received interventions following a CMR compared with those who received non-CMR interventions as part of a comprehensive MTM program. For this project, eligible individuals qualified for an MTM program. A positive medication change was defined as the addition of an appropriate medication or the removal of an inappropriate medication within 120 days of a pharmacist recommendation. Differences between the groups were calculated using the Wilcoxon rank sum test. RESULTS: During the 2-year period (2012 and 2013), 788,756 beneficiaries were enrolled in the MTM program and evaluated for potential MRPs. In both years, pharmacists recommended more medication changes per member for those receiving a CMR (0.81 in 2012 and 0.82 in 2013) compared with the non-CMR group (0.68 in 2012 and 0.61 in 2013; P value < 0.001 for both years). However, recommendations made via non-CMR interventions (representing the vast majority of all medication reviews) were more likely to result in a positive medication change (OR = 1.24, 95% CI = 1.21-1.28 for 2012; OR = 1.26, 95% CI = 1.22-1.30 for 2013). CONCLUSIONS: These quality improvement project results suggest that Medicare Part D beneficiaries participating in a university-based MTM program who received non-CMR interventions had a higher likelihood of having positive medication changes than those receiving CMRs. These results are enlightening and may provide initial evidence to support inclusion of a non-CMR performance metric for the Centers for Medicare & Medicaid Service's star ratings for MTM programs.
