Feasibility of wearable activity trackers in cystectomy patients to monitor for postoperative complications.

Background: To determine the feasibility of using wearables in patients undergoing radical cystectomy to monitor postoperative heart rate and activity and attempt to correlate these factors to complications and readmissions.

Materials And Methods: We conducted a prospective study of 20 patients undergoing radical cystectomy for bladder cancer between June 2017 and March 2018. Each patient was provided with a Garmin Vívofit heart rate (HR) activity tracker and instructed to wear it on their wrist for 30 days postoperatively.
