Map Details: Prevalence of Nonadherence and 5-Mile Driving Distances from Arkansas’s Hypertension Team-Based Care and Pharmacy Intervention Sites

Impact Statement

Since 2015, the Arkansas Department of Health has implemented hypertension team-based care at local health units (LHUs) in five counties and a screening and behavioral intervention at four pharmacies.

This map shows pockets of high rates of blood pressure renin-angiotensin system antagonist medication nonadherence located in the southeastern and eastern portion of the state. A series of inset maps show a close-up view of pharmacy and local health unit locations within select regions of the state.

Key Points

Major Findings

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%.

How the map will be used, or has been used

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.
