What this trial studies

This study evaluates the effectiveness of a mobile health (mHealth) strategy that utilizes text messaging to manage hypertension among homeless individuals in New York City. Participants aged 21 and older with uncontrolled blood pressure will be randomly assigned to either an intervention group receiving targeted hypertension management texts or a control group receiving standard health messages. The study will assess changes in blood pressure, adherence to clinic visits, and medication adherence over a 6-month period, alongside qualitative interviews with both patients and healthcare providers. The research aims to enhance health outcomes for a vulnerable population through innovative communication methods.

Who should consider this trial

Good fit: Ideal candidates are homeless individuals aged 21 and older with a diagnosis of hypertension and uncontrolled blood pressure.

Not a fit: Patients who are currently experiencing a hypertensive emergency or have severe comorbid conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve blood pressure control and overall health outcomes for homeless individuals with hypertension.

How similar studies have performed: Other studies have shown promise in using mobile health interventions for chronic disease management, suggesting potential success for this approach.
