Continuous Monitoring of Vital Signs After Hospital Discharge: A Feasibility Study

# Introduction Increasing demand for inpatient beds limits capacity and poses a challenge to the healthcare system. Early discharge may be one solution to solve this problem, and continuous vital sign monitoring at home could safely facilitate this goal. We aimed to document feasibility of continuous home monitoring in patients after hospital discharge. # Methods Patients were eligible for inclusion if they were admitted with acute medical disease and scheduled for discharge. They wore three wireless vital sign sensors for four days at home: a chest patch measuring heart rate and respiratory rate, a pulse oximeter, and a blood pressure (BP) monitor. Patients with ≥6 hours monitoring time after discharge were included in the analysis. Primary outcome was percentage of maximum monitoring time of heart rate and respiratory rate. # Results Monitoring was initiated in 80 patients, and 69 patients (86%) had ≥6 hours monitoring time after discharge. The chest patch, pulse oximeter, and BP monitor collected data for 88%, 60%, and 32% of the monitored time, respectively. Oxygen desaturation \24/minute); tachycardia (\>130/minute) lasting ≥30 minutes was observed in 28% of the patients. # Conclusions Continuous monitoring of vital signs was feasible at home with a high degree of valid monitoring time. Oxygen desaturation was commonly observed.
