Background: Achievement of treatment goals for patients with type 2 diabetes mellitus (T2DM) is suboptimal. This is in part driven by a lack of treatment intensification when warranted, termed "clinical inertia."
Objectives: To investigate time to treatment intensification and changes in A1C among pharmacist-physician managed (PPM) patients compared to usual medical care (UMC) in patients with T2DM.
Methods: Retrospective matched cohort study at 2 academic family medicine clinics. Patients in each cohort were matched 1:1 based on age (±5 years), primary care provider, gender, and race.
Results: A total of 50 patients met inclusion criteria. Mean time to treatment intensification was longer in the UMC cohort as compared with the PPM cohort (325 (66) days vs 200 (62) days [P = .50]). A higher percentage of patients in the PPM cohort achieved ≥0.5% reduction in A1C in comparison to the UMC cohort (60% vs 44%, respectively [P = .41]). Patients in the PPM cohort experienced a greater mean decrease in A1C from baseline when compared to patients in the UMC cohort (-1% (1.8%) vs -0.4% (2.2%) [P = .24]).
Conclusion: Patients exposed to a pharmacist in this retrospective matched cohort study experienced shorter time to treatment intensification and a greater reduction in A1C than those managed solely by a medical provider, although results were not statistically significant. Additional research is needed to evaluate the role of the pharmacist in improving clinical inertia in the management of T2DM.
