Perioperative Mobility Assessment of Acromegalic Patients Undergoing Endoscopic Endonasal Resection of Pituitary Adenomas Using Digital Phenotyping.

Methods to assess quality of life and recovery after endoscopic endonasal surgery (EES) for sellar lesions are limited and often biased by subjective patient-reported assessments. Objective in-situ assessments are lacking. Smartphone-based digital phenotyping has been increasingly studied across a variety of pathologies, utilizing built-in technologies to measure behavioral patterns pertaining to sleep, physical mobility, social interactions, and cognitive functioning, among others. We report our experience with smartphone-based digital phenotyping in two acromegalic patients treated with EES. Beiwe application was applied pre-operatively to passively collect global position system data in the pre- and postoperative period, including daily distance traveled, maximal distance traveled from home, number of separate places visited outside of home, and overall time spent at home. This study demonstrates the feasibility of DP for a small sample of acromegalic patients undergoing EES based on passively collected smartphone global position system data during the peri-operative period. This is part of a larger, ongoing study enrolling surgical patients as well as non-operative controls for comparison aimed at predicting postoperative outcomes with in-situ tool.
