Impact Statement

This map highlights the importance of assessing relative and absolute burden of nonadherence together in order to achieve maximum impact/reach of interventions to promote blood pressure (BP) medication adherence. Future work will be targeted to large, urban, high-burden areas (i.e. Buffalo, Syracuse, Rochester, Albany, Westchester, Long Island).

This map highlights geographic differences in the percent of RASA nonadherence among Medicaid members, as well as the count of Medicaid members who are identified as being nonadherent to RASAs.
Key Points

Major Findings

Overall, urban areas of NYS experience both a high relative (%) and absolute (#) burden of BP medication nonadherence. While the relative burden of nonadherence is lower in New York City compared to other areas of the state, the absolute burden is significant due to the large population size. Among NYS Medicaid members, the prevalence of RASA medication nonadherence by county ranged from a low of 27.9% in Lewis county to a high of 46.2% in Schenectady county. The count of Medicaid members who are identified as nonadherent ranged from 51 in Schuyler county to 26,304 in Kings county, with a statewide median of 359.

How the map will be used, or has been used

Findings have been shared with NYS Department of Health program staff working on hypertension initiatives, including the Office of Quality and Patient Safety and the Division of Chronic Disease Prevention. This map has been used to help allocate resources to areas with a high burden of medication nonadherence.
