Did a simple phone call keep chronic patients out of the hospital?
NCT ID NCT04359875
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a systematic phone call from a medical student, supervised by a general practitioner, could reduce hospitalizations in patients with chronic heart or mental health conditions during the COVID-19 lockdown in France. Over 22,000 patients aged 70 and older were enrolled. The goal was to see if proactive outreach could catch problems early and prevent emergency care.
