Evaluation of a Diabetes Coaching Program on Clinical Outcomes in a Self-Insured Grocery Chain

Abstract

Background: Diabetes is among the most prevalent and costly disease states to treat. Many self-insured employers offer employee wellness programs to decrease healthcare expenditures for chronic illnesses, such as diabetes. Existing literature demonstrates that pharmacists can positively impact treatment of patients with diabetes and assist in lowering costs of care, but no current literature examines pharmacist intervention within an employee wellness program over a prolonged period of time. Objectives: To quantify the hemoglobin A1c (HbA1c) lowering achieved through participation in a pharmacist-led diabetes coaching program within a self-insured company. Methods: A retrospective chart review was conducted at a self-insured grocery store chain in the Kansas City area with an employee wellness program called Start Now. Patients who enrolled in the Start Now Program for Diabetes Care (SN-DM) between July 1, 2008 and July 1, 2021 with at least two documented HbA1c measurements were included in the analysis. Results: A total of 355 charts were included in the analysis. The average HbA1c reduction observed in program patients was 0.61% ( P < .001). At baseline, 40% of program patients were considered to have controlled diabetes (A1c <7%) compared with 60% of patients at most recent HbA1c ( P < .001). There was no correlation between HbA1c lowering and number of pharmacist coaching visits; however, greater HbA1c lowering was observed in patients with a higher baseline HbA1c. Conclusion: Patients who participated in the SN-DM program achieved a significant decrease in mean HbA1c. More patients were considered controlled at last or most recent HbA1c according to the American Diabetes Association guidelines.
