• Assessment of Physical Activity to Determine When Patients Return to Baseline Levels of Activity Following Outpatient Inguinal Hernia Surgery Scottsdale/Phoenix, Ariz.

  The purpose of this study is to use wearable monitoring devices to assess patient activity and sleep patterns before and after outpatient inguinal hernia surgery to determine when these parameters return to baseline.

• Resident and Staff Sleep as measured by wearable devices Scottsdale/Phoenix, Ariz.

  Background Sleep deprivation of medical staff and especially trainees has been a concern for many years. There is growing evidence that lack of sleep by staff and trainees increases risks of acute and chronic illness and injury. Concern about judgement and performance have led to significant regulation and reduction of  trainee work hours and frequency of call over the past two decades. There is conflicting evidence whether these changes have had a positive impact on patient care. There is a need to objectively measure the range of sleep obtained and activity performed by staff and resident physicians across different work shift patterns and call schedules. This project will use wearable activity monitors to objectively measure the amount and quality of sleep under several different shift and call schedule patterns.
