Beyond the physical: Digital phenotyping and the complexity of surgical recovery

Digital phenotyping, the moment-by-moment quantification of human behavior in situ using data from personal digital devices, is a potentially powerful tool for increasing understanding of recovery from surgery. While physical metrics are often emphasized, measures of emotional, cognitive, and psychosocial function are important aspects for the surgeon, a better understanding of which can lead to improved preoperative counseling and optimization, shared decision-making, and monitoring of recovery after surgery. A growing number of studies have begun to characterize these techniques. Ultimately, this tool may provide rich data about the perioperative period that will help surgeons and patients alike.
