Clinical Pharmacy Specialist Collaborative Management and Prescription of Diabetes Medications with Cardiovascular Benefit

Abstract

Background Involvement of Clinical Pharmacy Specialists (CPS) in the care of patients with diabetes mellitus (DM) has been demonstrated to be beneficial. Whether this positive impact applies to increased use of cardiovascular risk-reducing medications is less well established. Objective To determine the association of CPS co-management on the prescription of diabetes medications with proven cardiovascular benefits for patients with DM and established cardiovascular disease in the primary care setting. Methods This retrospective cohort study evaluated patients in a Veterans Affairs health-system in primary care settings from February 1, 2019, through January 31, 2020. Patients were included if they had type 2 DM treated with at least one medication and had CVD. Patients were grouped into two cohorts for comparison, those with CPS co-management and those without. The primary outcome was the proportion of patients in each group with new prescriptions for empagliflozin or liraglutide initiated during the study timeframe. Results In total, 8058 patients were found eligible for inclusion in the study. Clinical co-management by a CPS was provided to 2099 patients. Study medications were prescribed, approved, and initiated in 596 patients during the study period, including 391 (18.6%) in the CPS group and 205 (3.4%) in the non-CPS group (P < .001). Conclusion This study showed CPS involvement is associated with increased prescribing of diabetes medications with proven cardiovascular benefits.
