Results from a mailed promotion of medication reviews among Department of Defense beneficiaries receiving 10 or more chronic medications.

Background: Like many payers, the Department of Defense (DoD) has limited ability to work directly with prescribers to ensure appropriate medication use. Many older beneficiaries are prescribed multiple maintenance medications, placing them at higher risk for adverse drug interactions, contraindicated medication use, and other polypharmacy-related problems. Medication reviews may mitigate these risks, but the optimal venue for medication therapy management is unclear.
