Objective: To provide program methodology and outcomes data identifying the impact of clinical pharmacy services (CPSs) in patients with type 2 diabetes. Design: Longitudinal pre-post cohort study. Setting: Regional primary care group in Buffalo, NY, during 2006-2007. Patients: Patients with type 2 diabetes identified by their primary care providers were referred to the MedSense program; a pharmacist-led, patient-centered pharmacotherapy management program developed through university collaboration with a regional primary care physician group. Interventions: Education, clinical assessments, provider recommendations, and longitudinal follow-up of treatment goals provided by MedSense pharmacists. Main outcome measures: Clinical outcomes were followed for 1 year from the index date for primary diabetes endpoints (glycosylated hemoglobin and fasting plasma glucose) and accompanying metabolic parameters (body mass index, blood pressure, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides). Economic endpoints from the payer perspective were also followed for 1 year from the index date for medical and prescription-related costs. Results: Primary diabetes endpoints were significantly reduced versus baseline at the 6-month (-1.1%; P < 0.0001, -39 mg/dL; P = 0.003) and 12-month (-1.1%; P < 0.0001, -35 mg/dL; P = 0.005) assessments. Improvement rates were observed for all accompanying metabolic parameters at each assessment (range 40-64%). Geometric mean costs tended to decrease versus baseline at 6-month (-$84; P = 0.785) and 12-month (-$216; P = 0.414) assessments, despite nominal increases in diabetes and total medication costs. Conclusion: In this CPS model, there were initial and sustained reductions in the primary diabetes endpoints and a high rate of improvement for accompanying metabolic parameters. Concurrent with clinical improvements, total direct medical costs were reduced despite an increase in antidiabetic medication and total medication costs.
