Prevalence of Nonadherence and 5-Mile Driving Distances from Arkansas's Hypertension Team-Based Care and Pharmacy Intervention Sites

Four of the five LHU intervention sites, shown as red triangles, and all the pharmacy intervention sites, shown as green circles, were located in counties with medication nonadherence ≥22.4%.

This map and the techniques applied here will help the Arkansas Department of Health scale up its hypertension and diabetes prevention and control efforts in Arkansas to reduce mortality, emergency room visits, and hospitalization rates due to these conditions.

County-level of nonadherence prevalence data for the antihypertensive renin-angiotensin system antagonist group of drugs among Medicare Part D beneficiaries were mapped. Three strata were used to define medication nonadherence. LHU intervention sites and pharmacy intervention sites were plotted with 5-mile driving distances to show population access to these sites.
