What is the purpose of this trial?

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.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. It seems to focus on managing blood pressure through text message reminders, so you may continue your current treatment unless advised otherwise by your doctor.

Is it safe to use text message reminders for managing high blood pressure?

Research on using text message reminders for managing high blood pressure, especially among homeless individuals, suggests that it is a safe approach. Participants in studies have shown positive attitudes towards receiving health-related text messages, indicating that this method is generally well-received and does not pose safety concerns.12345

How is the mHealth treatment for hypertension in homeless persons unique?

This treatment uses text message reminders to help homeless individuals manage high blood pressure, which is unique because it leverages mobile health technology to improve communication and support, addressing the specific challenges faced by this population.13456

What data supports the effectiveness of the treatment mHealth for Hypertension in Homeless Persons?

Research shows that text messaging has been effective in improving health care engagement and medication adherence in homeless populations, and has helped control high blood pressure in the general population. Homeless individuals are generally supportive of using text messages for health care, which suggests that this approach could be beneficial for managing high blood pressure among them.13456

Published Research Related to This Trial

This study will evaluate the effectiveness of a 6-month SMS texting program in reducing blood pressure and improving medication adherence among 120 adults experiencing homelessness with uncontrolled hypertension, using a randomized controlled trial design.
In addition to measuring health outcomes, the study will assess the acceptability and experiences of both patients and healthcare providers regarding the SMS intervention, providing valuable insights into its feasibility in this population.

This study will evaluate the effectiveness of a 6-month SMS texting program for managing diabetes in 100 adults experiencing homelessness, measuring changes in HbA1c and adherence to self-care activities over 9 months.
The research will also gather insights from both patients and healthcare providers to assess the acceptability and experiences of the SMS program, aiming to improve diabetes management in this underserved population.

Text messaging interventions for appointment reminders and medication adherence suggestions showed a trend towards reducing no-show rates and improving medication adherence among a homeless population, with no-show rates at 21.0% for the intervention group compared to 30.6% for the control group.
Although the results did not reach statistical significance, the intervention group reported a higher increase in self-reported medication adherence (from 8.27 to 9.84) compared to the control group (from 8.27 to 8.68), indicating potential effectiveness in enhancing patient engagement.
