Uncontrolled Hypertension Among the Homeless

Plain-language summary

This study is designed to assess the effect of implementing a mobile health (mHealth) strategy using text messaging for hypertension (HTN) management among hypertensive homeless persons with uncontrolled blood pressure age 21 or older in shelter-clinics in New York City (NYC). The study uses a randomized clinical trial design (homeless, n=120) and semi-structured interviews (homeless, n=30; providers, n=20). The control group will receive text messages for usual standard care/healthy lifestyle during a 6-month follow-up period. The intervention group will receive text messages geared towards both standard care/healthy lifestyle and blood pressure control. At the end of study period, the investigators will assess changes in blood pressure (BP) measurements, adherence to clinic visits, and adherence to medication, and the investigators will compare them between the two groups. Qualitative interviews with both patients and providers who provide services to the homeless in shelter settings will develop a better understand barriers and opportunities regarding BP control. The investigators hypothesize that those individuals randomized to the intervention will experience a reduction in blood pressure (8mmHg systolic BP or diastolic BP) and will exhibit better adherence to blood pressure medications and appointments compared to the control group.
