Phone app aims to keep heart patients out of hospital
NCT ID NCT03358303
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a smartphone app called Medly that helps heart failure patients monitor their health after a hospital stay. The app reminds patients to check their weight and symptoms, and sends the information to their care team. The goal is to see if using the app improves patients' quality of life and reduces the chance of being readmitted to the hospital within 30 days.
