Preoperative REM sleep is associated with complication development after colorectal surgery.

Background: While total sleep duration and rapid eye movement (REM) sleep duration have been associated with long-term mortality in non-surgical cohorts, the impact of preoperative sleep on postoperative outcomes has not been well studied.

Methods: In this secondary analysis of a prospective observational cohort study, patients who recorded at least 1 sleep episode using a consumer wearable device in the 7 days before elective colorectal surgery were included. 30-day postoperative outcomes among those who did and did not receive at least 6 h of total sleep, as well as those who did and did not receive at least 1 h of rapid eye movement (REM) sleep, were compared.

Wearable technology and the association of perioperative activity level with 30-day readmission among patients undergoing major colorectal surgery.

Background: The proliferation of wearable technology presents a novel opportunity for perioperative activity monitoring; however, the association between perioperative activity level and readmission remains underexplored. This study sought to determine whether physical activity data captured by wearable technology before and after colorectal surgery can be used to predict 30-day readmission.

Methods: In this prospective observational cohort study of adults undergoing elective major colorectal surgery (January 2018 to February 2019) at a single institution, participants wore an activity monitor 30 days before and after surgery.

Wearable Technology in the Perioperative Period: Predicting Risk of Postoperative Complications in Patients Undergoing Elective Colorectal Surgery.

Background: The implementation of protocolized care pathways has resulted in major improvements in surgical outcomes. Additional gains will require focused efforts to alter preexisting risk. Prehabilitation programs provide a promising avenue for risk reduction.
