Map Details - Relative Differences in High Blood Pressure (HBP) Medication Adherence Among Medicaid Members, by County
This map highlights the existence of major geographic disparities in blood pressure medication adherence, even within the Medicaid population.
This map was developed as a part of the GIS Capacity Building Project. Learn more about the project.
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.
