Characterizing Medicare Medication Therapy Management program enrollees with central nervous system–active polypharmacy

More than 1 in 10 MTM enrollees experience CNS-active polypharmacy, which is higher than the general Medicare fee-for-service beneficiary population. MTM enrollees with CNS-active polypharmacy are more likely to be male, dually enrolled in Medicaid, and with greater comorbidity burden and prior-year use of health care and medications, suggesting that interventions for this population may need to account for additional clinical and socioeconomic needs. Despite being at greater risk of adverse drug events including impaired cognition and falls, just over one-third of MTM enrollees with CNS-active polypharmacy participate in a CMR, suggesting opportunity for more targeted outreach and intervention by MTM programs, Part D plan sponsors, and Centers for Medicare & Medicaid Services.
