Enhanced Vitals Monitoring After Major Surgery Trial

"For participants in the intervention group, they will receive the enhanced continuous vital sign monitoring, on top of the standard of care monitoring as prescribed per the care team. The enhanced monitoring will be provided during the entire time period of hospitalization (up to 30 days after surgery), using the Philips monitor (i.e. heart rate and oxygen saturation continuously and blood pressure once an hour while awake). Participants and caregivers will be educated how to put on and off the devices by the study coordinator.~When participants return home, they will perform thrice-daily monitoring using the Cloud DX Inc. Home kit and daily questionnaires at home 7 days after discharge (or 30 days after surgery, whichever occurs first)."
