Background:

Diabetic retinopathy (DR) is a progressive, sight-threatening long-term complication of diabetes. Diabetes disease management reduces the risk of developing or progression to a severe form of DR. However, there are no reports of the potential role of pharmacists in DR progression.

Objective:

For this study, we performed a retrospective data analysis of patients with diabetes seen at cardiovascular risk reduction services provided by pharmacists with an objective to determine the potential role of pharmacists in the DR progression. These services involve pharmacists working in collaborative drug therapy management (CDTM), using a collaborative practice agreement (CPA) with primary care physicians.

Methods:

Patient records and ophthalmological notes were collected for 317 individuals seen by the pharmacists (intervention group) and 320 individuals seen only by a physician (control).

Results:

Statistical analysis was performed on 148 individuals in an intervention group and 120 individuals in the control group for which complete records were available. Retinopathy progression remained stable in 89.6 % of individuals in the intervention group compared to 87.9% in the control group. Moreover, the relative risk of retinopathy progressing to a severe form was 1.17 for the control group compared the intervention group.

Conclusions:

Our studies provide a proof-of-concept that pharmacists-managed care possesses a potential role in protection from DR, and paves a way for future pharmacists managed care with an emphasis on reducing diabetic complications.
