This study is set out to observe heart-rate and related bio-metric indicators in Obstetrics and Gynecology residents during their duty hours, together with self-reporting of fatigue and tasks performances, in order to model possible relationships between the two.

There are vast evidences of the harmful consequences of fatigue in medical residents, consequently, leading to poor task performances and in some cases may cause injury to the patients. Medically, fatigue is a non-specific symptom, which means that it has many possible causes and accompanies many different conditions. Elevated fatigue is an indication that a person may not be fit-to-task (i.e., task efficacy).The investigators main goal is to use readily available body-worn sensors, such as an activity wrist-band, to continuously monitor for fatigue as a possible antecedent to predictions of task-efficacy in the area of Obstetrics and Gynecology. This study is anchored in prior research which established basic models that correlate between heart-rate variability (HRV) and fatigue. Specific to this study, the investigators would like to further establish the validity of such models at the individual level, also with the perspective of fatigue as an early predictor of task performance related to practices in Obstetrics and Gynecology. The investigators aim is to extend HRV based models with additional personal measures (e.g., age, weight, activity level), possibly with the extraction of additional data-driven features, to improve model accuracy at the individual level. The investigators will also try to find relationships between such measurements and task effectiveness via the gathering of self-reports regarding on-the-job task performances.
