About 70% of US adults, ages 65 or older, have hypertension, but only about half have the condition under control. According to the report, about 5 million people — one in four adults ages 65 or older with Medicare Part D and a prescription for hypertension medication — are not taking their medication as directed. Medication adherence is critical to hypertension control. Researchers looked at disparities in adherence rates based on factors including geography, race/ethnicity, gender, income status, and medication class. The percentage of Medicare Part D enrollees not taking their blood pressure medicine is higher among American Indians/Alaska Natives (39 percent), Black (36 percent), and Hispanic (34%) groups. Geographic disparities were also found. CDC encourages health care systems to help people understand the importance of blood pressure control and how taking blood pressure medicine (along with a healthy diet and exercise) lowers risk of heart disease, kidney disease, and stroke.

NACDD held a number of events in 2015 to help states in their efforts to support clinical providers in improving the percentage of patients who take hypertension medications as prescribed. This NACDD document summarizes the webinars and has links to the presentations and related resources.
