Wearable activity to see if daily movement predicts perioperative risk in older adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this single-center prospective cohort, researchers will use a wearable accelerometer to monitor preoperative physical activity and sleep in adults 65+ scheduled for general anesthesia with tracheal intubation. They will relate activity metrics such as sedentary time, light to vigorous activity, steps, and sleep duration to cardiovascular autonomic function assessed with perioperative noninvasive monitoring, focusing on baroreflex-related indices. The primary outcome is post-induction hypotension, with several intraoperative measures as secondary outcomes. The study builds on the idea that habitual activity relates to autonomic regulation and may inform risk of perioperative hemodynamic instability. It aims to clarify whether accelerometer-derived metrics add value beyond standard assessments for predicting perioperative risk in elderly patients.
