NCT ID NCT04068584
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a device called SMART ANGEL, which tracks heart rate, blood pressure, oxygen levels, and symptoms like pain and nausea at home, could reduce unplanned hospital visits, doctor calls, or extra prescriptions after major or intermediate outpatient surgery. Over 1,200 adults participated. The goal was to see if active home monitoring improves the quality of follow-up care.
