Evaluation of pharmacist consults within a collaborative enhanced primary care team model to improve diabetes care

Abstract

Background An enhanced primary care team model was implemented to provide proactive, longitudinal care to patients with diabetes, grounded in close partnership between primary care providers (PCPs), nurses, and Medication Management Services (MMS) pharmacists. The purpose of this study is to evaluate the impact of the MMS pharmacist involvement in the enhanced primary care model for patients with diabetes. Methods This retrospective cohort study compared the quality of diabetes care between patients referred to a pharmacist and propensity score matched controls who were not. Eligible patients were adults (age 18 to 75 years) enrolled in the enhanced primary care team process who did not meet at least one of four diabetes quality indicators at 13 Mayo Clinic Rochester primary care practice locations. The intervention examined was asynchronous e-consults by pharmacists affiliated with the primary care practice. Main measures The primary outcome was change in the proportion of patients meeting the composite of four diabetes treatment goals (D4), including hemoglobin A1c (HbA1c) control, blood pressure control, aspirin use, and statin use at six months from enrollment among patients who received pharmacist intervention compared to matched patients who did not. Secondary outcomes were each of the D4 goal individually. Results The proportion of patients meeting the D4 increased with pharmacist e-consults (N = 85) compared to matched controls with no review (N = 170) (27% vs 7.0%, p<0.001). The change in patients meeting treatment goals of HbA1c (12.9% vs 4.1%, p = 0.020), blood pressure (9.4% vs 2.4%, p = 0.023), aspirin use (10.6% vs 2.9%, p = 0.018), and statin use (17.6% vs -1.2%, p<0.001) all increased with pharmacist e-consults. Conclusions Pharmacist engagement in the enhanced primary care team improved diabetes management. This supports the inclusion and utilization of pharmacists in multidisciplinary efforts to improve diabetes care.
