Summary
This study will screen over 7,000 adults aged 40+ living in affordable housing in New York City for undiagnosed high blood pressure and glaucoma. Participants who need follow-up care will be randomly assigned to receive text message reminders or usual care. The goal is to see if text support helps more people attend their doctor appointments and get diagnosed or treated.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could show that simple text message reminders help people get follow-up care for high blood pressure and glaucoma, improving early detection in underserved communities.
- What could go wrong
- This is an early-stage implementation study, not a treatment trial. It may not prove that screening or reminders actually improve long-term health outcomes.
