Impact on drug cost and use of Medicare Part D of medication therapy management services delivered in 2007

Among patients who received MTM services in 2007, drug costs decreased for those who received service from community pharmacists, decreased somewhat for patients who received service from a call center pharmacist, and were unchanged for those who received MTM via mailing. Further studies are needed to assess the effect of various types of MTM interventions on financial, clinical, and humanistic outcomes.
