Class of 2013 Abstract / Specific Aims: To compare the Comprehensive Medication Review (CMR) rate for Workflow Model #1 (used in 2010) to the CMR rate for Workflow Model #2 (used in 2011) at the Medication Management Center (MMC). Methods: A retrospective database analysis was completed in which Comprehensive Medication Review (CMR) completion rates for 2010 and 2011 were assessed. Comparison included only Center for Medicare and Medicaid Services (CMS) contracts that the Medication Management Center (MMC) provided Medication Therapy Management (MTM) services for both in 2010 and 2011. Data was used to determine the effect a process change had on CMR participation rate at the MMC and best practices for improving the rate of Medication Therapy Management Program (MTMP) beneficiaries participating in a CMR. Main Results: In 2010, patient participation and response to a CMR offer letter was low (0.2%). The changes in process yielded an increase in the CMR completion rate (6.93%); this in turn yielded higher performance measurements for prescription drug plans. Conclusion: Workflow modifications, including a pro-active secondary CMR offer, led to a marked increase in member participation and CMR rates. Patients are more apt to consent to a CMR if they are called for a specific medication related problem. It is recommended to continue to convert TMR calls to CMRs whenever possible, monitor CMR rates at least quarterly, and make cold calls where needed to increase CMR percentages.
