Impact of Ambulatory Care Pharmacist-Led Management on Hemoglobin A1c Values among Patients with Uncontrolled Diabetes in a Primary Care Clinic vs Usual Care over Two Years

Abstract

Background: Literature has shown the positive impact of ambulatory care pharmacists on diabetes management, yet additional research on clinical outcomes compared to traditional care models is warranted. Objective: The objective of this study is to evaluate the impact of an ambulatory care pharmacist on glycemic control over two years compared to patients who received usual care. Methods: This retrospective cohort study matched patients with a baseline hemoglobin A1c (HgbA1c) ≥8% managed by the ambulatory care pharmacist to patients who received usual care. The primary outcome was the mean change in HgbA1c over two years. The secondary outcomes were to evaluate the difference in (1) the proportion of patients achieving HgbA1c 8% managed by an ambulatory care pharmacist had twice the HgbA1c reduction and significantly more utilization of GLP-1RA and SGLT2 inhibitors as compared to controls provided usual care.
