Emergency department visits provide an opportunity to identify people with undiagnosed, untreated, or uncontrolled high blood pressure. In Reach Out, we will test whether a mobile health intervention yields a greater reduction in blood pressure than usual care among individuals identified with high blood pressure during a safety-net emergency department visit. Subsequently, we will estimate the reduction in heart attack, stroke, and dementia if Reach Out were implemented across all U.S. safety-net emergency departments.
