Hypertension, or high blood pressure, is a major health problem affecting more than 115 million people in the United States and representing $131 billion in health care costs annually. Although it is known how to effectively treat hypertension, not all patients and health systems have access to or are able to use such treatments. It is important to study how to implement effective treatments for hypertension across a wide range of settings serving diverse patients.

This study, Comparing Hypertension Remote Monitoring Evaluation Redesign (CHARMED), aims to evaluate different ways to use home blood pressure checking. The study team will offer patients different ways of checking blood pressure at home and offer primary care clinics different types of training and support to help teams of nurses, pharmacists, medical assistants and doctors treat high blood pressure. This study design allows for testing of a number of different factors simultaneously. It is expected that the study will identify effective strategies to implement, maintain and scale home blood pressure monitoring for diverse patients.

This research can help people with hypertension as well as health systems that are interested in treating hypertension using remote blood pressure checking. The findings may be particularly helpful for people who face barriers to using remote blood pressure monitors, such as those with limited English proficiency, because different self-management and outreach approaches will be tested. The study may also help health systems that struggle with monitoring patient care in between visits, such as sites that are short-staffed, because the study will help show how to better support their workflows for managing hypertension.

The study team will include 2500 adults with hypertension in this study. This will be achieved by recruiting participants from primary care clinics at three large safety-net health systems.
