Diabetes self-management education improves medication utilization and retinopathy screening in the elderly.

Abstract

AIMS: To evaluate the effect of diabetes education program attendance, which provides patients with diabetes self-management education, on prescriptions for cardiovascular risk reduction, prescriptions for diabetes treatments, and visits for retinopathy screening. METHODS: A population based cohort study of residents of Ontario, Canada with diagnosed diabetes aged ≥65 years was performed using administrative databases. Diabetes education program attendance was identified using a registry of visits to all diabetes education programs in the province in 2006. Using propensity score methods, 22,606 diabetes education program attendees were matched to an equal number of non-attendees. The proportions of patients with prescriptions filled and with ophthalmology/optometry visits were compared. RESULTS: Patients attending diabetes education programs had greater utilization of statins (70.6%) than non-attendees (69.4%, p<0.0001). Diabetes education program attendance was also associated with greater utilization of glucose lowering medications (83.7% vs. 82.0%, p<0.0001), antihypertensive medications (90.2% vs. 89.7%, p<0.0001), angiotensin converting enzyme inhibitors/angiotensin receptor blockers (79.8% vs. 78.9% p<0.0001), and glucose monitoring strips (82.2% vs. 65.6%, p<0.0001); and visits to ophthalmology/optometry (78.7% vs. 72.7%, p<0.0001). CONCLUSIONS: Diabetes self-management education at diabetes education programs is associated with better quality of care in the elderly in Ontario.
