Continuous Versus Intermittent Ward Monitoring

Sponsor: The University of Texas Health Science Center, Houston

Summary

The investigators will randomize adults having major non-cardiac inpatient surgery to blinded versus unblinded continuous postoperative vital sign monitoring (saturation, ventilation, and heart rate). The investigators will use a wearable, untethered, and battery-powered sensor (Masimo Radius PPG, Masimo, Irvine, CA) that wirelessly connects to a Masimo monitor and continuously records saturation, ventilation, and pulse rate. The primary outcome will be areas-exceeding-thresholds for desaturation (\<85%), bradypnea (\<7 breaths/min), tachypnea (\>30 breaths/min), tachycardia (heart rate \>130 beats/min), and bradycardia (heart rate \<45 beats/min). These exposure thresholds represent a balance between events that are clinically meaningful and excessive alarms that will discourage clinician participation. The investigators expect about 2 alerts per patient per day with these thresholds, with most being considered informative or actionable by nurses. In unblinded patients, clinician alerts will be activated at these thresholds.
