The utility of wearable devices in the perioperative period.

Purpose of review: Improved perioperative patient monitoring is a crucial step toward better predicting postoperative outcomes. Wearable devices capable of measuring various health-related metrics represent a novel tool that can assist healthcare providers. However, the literature surrounding wearables is wide-ranging, preventing clinicians from drawing definitive conclusions regarding their utility. This review intends to consolidate the recent literature on perioperative wearables and summarize the most salient information.

Recent findings: Wearable devices measuring cardiac output and colonic motility have recently been piloted with mixed results. Novel measurement techniques for established metrics have also been studied, including photoplethysmography devices for heart rate and blood pressure along with resistance thermometers for temperature. Nuanced methods of synthesizing data have been piloted, including machine-learning algorithms for predicting adverse events and trajectory curves for step count progression. Wearable devices are generally well accepted, although adjuvant support systems have improved patient satisfaction.

Summary: Perioperative wearables are valuable tools for tracking postoperative health metrics, predicting adverse events, and improving patient satisfaction. Future research on removing barriers such as technological illiteracy, artifact generation, and false-positive alarms would enable better integration of wearables into the hospital setting.
