Association of Wearable Derived Pulse Rate Variability With Pediatric Appendectomy Complications

Abstract

Postoperative recovery of children is difficult to gauge by parents after hospital discharge. Consumer wearable devices (CWD) generate valid and near real-time pulse rate data, integer pulse rate variability (PRVi), that can serve as digital biomarkers for the onset of complications during post-discharge recovery. This study sought to explore whether pediatric patients with surgical complications after appendectomy exhibited a CWD-derived PRVi trajectory that differs from the normative PRVi recovery trajectory.
