Impact Statement

This map highlights the existence of major geographic disparities in blood pressure medication adherence, even within the Medicaid population.

This map shows results of statistical significance testing of differences between county-level medication adherence rates for the combined 2015–2016 Michigan Medicaid population 18–64 years old. Berrien, Kalamazoo, Kent, Ingham, Wayne, Bay, Tuscola, Genesee, Saginaw, Shiawassee, and Ogemaw counties had statistically lower rates of medication adherence in comparison to all other counties. Washtenaw and Jackson counties and counties in the Traverse City area and the eastern Upper Peninsula had adherence rates comparable to all other counties. Genesee and Saginaw counties had the largest difference, with adherence rates 10 percent to 15.3 percent lower than all other counties.
Key Points

Major Findings

This map identifies counties that have statistically lower adherence to blood pressure medications in the Medicaid population, as well as the magnitude of the difference.

How the map will be used, or has been used

While also taking into consideration the average number of Medicaid members in each county (shown in the prior map), results will be used to prioritize the Michigan Department of Health and Human Services’ efforts to improve high blood pressure medication adherence.
