Patient self-management program for diabetes: first-year clinical, humanistic, and economic outcomes

Abstract

Objective: To assess the outcomes for the first year following the initiation of a multisite community pharmacy care services (PCS) program for patients with diabetes.

Design: Quasi-experimental, pre-post cohort study.

Setting: 80 community pharmacy providers with diabetes certificate program training who were reimbursed for PCS by employers in Greensboro, N.C., Wilson, N.C., Dublin, Ga., Manitowoc County, Wis., and Columbus, Ohio.

Patients: 256 patients with diabetes covered by self-insured employers' health plans.

Interventions: Community pharmacist patient care services using scheduled consultations, clinical goal setting, monitoring, and collaborative drug therapy management with physicians and referrals to diabetes educators.

Main outcome measures: Changes in glycosylated hemoglobin (AIC), low-density lipoprotein cholesterol (LDL-C), blood pressure, influenza vaccinations, foot examinations, eye examinations, patient goals for nutrition, exercise, and weight, patient satisfaction, and changes medical and medication utilization and costs.

Results: Over the initial year of the program, participants' mean A1C decreased from 7.9% at initial visit to 7.1%, mean LDL-C decreased from 113.4 mg/dL to 104.5 mg/dL, and mean systolic blood pressured decreased from 136.2 mm Hg to 131.4 mm Hg. During this time, influenza vaccination rate increased from 52% to 77%, the eye examination rate increased from 46% to 82%, and the foot examination rate increased from 38% to 80%. Patient satisfaction with overall diabetes care improved from 57% of responses in the highest range at baseline to 87% at this level after 6 months, and 95.7% of patients reported being very satisfied or satisfied with the diabetes care provided by their pharmacists. Total mean health care costs per patient were $918 lower than projections for the initial year of enrollment.

Conclusion: Patients who participated in the program had significant improvement in clinical indicators of diabetes management, higher rates of self-management goal setting and achievement, and increased satisfaction with diabetes care, and employers experienced a decline in mean projected total direct medical costs.
