Text message reminders to help control high blood pressure

This trial is testing a mobile health program called Reach Out that uses text messages and personalized support to help people manage high blood pressure. The program is designed specifically for people who visit the emergency department with very high blood pressure readings and may not have regular access to primary care. Researchers want to see if this text-based approach—combined with help scheduling doctor visits and arranging transportation—works better than standard care instructions alone.

High blood pressure is the leading cause of heart disease, and Black Americans and low-income Americans are disproportionately affected and have lower rates of blood pressure control. The trial exists to test a new way of catching and treating people whose high blood pressure has been missed or undertreated by the healthcare system, especially those who may fall through the cracks.
