Remote Monitoring of Patients with COVID-19 after Hospital Discharge with Connected Health Platform: Outcomes and Quality of Life

Background: Telemonitoring with applications and connected devices facilitates a more accessible and efficient attention. Its implementation has been accelerated thanks to the pandemic by COVID-19, where they have allowed the continuity of care. Objective: To evaluate the efficacy of a remote monitoring platform for the outpatient follow-up after hospital discharge by COVID-19. Methods: Prospective observational study of patients discharged from the hospital with COVID-19 infection between March 23 and May 25, 2020, who were followed for one month with the Connected Health telemonitoring platform. The mobile phone application connected to a pulse oximeter, allowed to measure vital signs and answer health questionnaires (EQ5D3L and CAT) daily, and alert the medical team that could be contacted by video consultation. Results: 95 patients (64% male) with a mean age of 54 (SD 26-81) years were included. The application allowed the detection of alerts for pain (80% of patients) and a decrease in oxygen saturation (12%). No patient required hospital readmission or presented complications. The application allowed strict monitoring of symptoms and quality of life. The main symptom was severe pain (59% of patients) followed by anxiety or depression (25%). The average state of health was 65 (SD 20-100). COVID-19 caused a low impact on the quality of life of 62% of the patients, although 8% reported a significant limitation, due to shortness of breath and leaving the house. Conclusion: telemonitoring allows a safe remote monitoring of patients after hospital discharge by COVID-19. The Connected Health application has allowed the measurement of oxygen saturation, symptoms and quality of life, and the detection and management of alerts by the medical team through video consultation.
