Registered outcomes 13
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Total sleep hours per night | 180 days | Sleep (hours per night) will be objectively measured nightly. | ClinicalTrials.gov |
| Primary | Executive function test (Stroop test), daily | 180 days, measured following each 24 hour call shift (weekly) | The Stroop test demonstrates cognitive interference where a delay in the reaction time of a task occurs due to a mismatch in stimuli. A basic task that demonstrates this effect occurs when there is a mismatch between the name of a color (e.g. "blue" or "red") and the color it is printed on (i.e the word "red" printed in blue ink instead of red ink). When asked to name the color of the word it takes longer and is more prone to errors than when the color of the ink matches the name of the color. The test consists of 3 labels, each displaying the name of a color (not necessarily tinted in the color which they denote). The subject is tasked to tap on the appropriate label at the bottom, whose text denotes the ink color of the top label. The total score is the number of correct answers in 60 seconds (+1), minus the number of incorrect answers (-1). Scores may range from 0-60, with mean scores in the range of 10-20. The stroop test will be performed daily (every morning). | ClinicalTrials.gov |
| Secondary | REM sleep hours, nightly | 180 days | REM sleep hours will be measured nightly by the WHOOP strap 4.0. | ClinicalTrials.gov |

| Secondary | Resting heart rate, nightly | 180 days | Resting heart rate will be measured nightly by the WHOOP strap 4.0. | ClinicalTrials.gov |
| Secondary | Heart rate variability, nightly | 180 days | Heart rate variability will be measured nightly by the WHOOP strap 4.0. | ClinicalTrials.gov |
| Secondary | Respiration rate, nightly | 180 days | Respiration rate will be measured nightly by the WHOOP strap 4.0. | ClinicalTrials.gov |
| Secondary | Pulse oximetry, nightly | 180 days | Pulse oximetry will be measured nightly by the WHOOP strap 4.0. | ClinicalTrials.gov |
| Secondary | Body temperature, nightly | 180 days | Body temperature will be measured nightly by the WHOOP strap 4.0. | ClinicalTrials.gov |
| Secondary | Average duty hours per week | 180 days | Duty hours will be self-reported every week | ClinicalTrials.gov |
| Secondary | Perceived Stress Scale-4 (PSS-4) | 180 days | The PSS-4 consists of 4 items that assess perceived stress. The items are scored on a 4-point scale. This survey will be administered biweekly. | ClinicalTrials.gov |
| Secondary | Patient Health Questionnaire-9 (PHQ-9) | 180 days | The Patient Health Questionnaire-9 (PHQ-9) consists of 9 items that assess major depressive disorder. This survey will be administered biweekly. PHQ-9 score can range from 0 to 27, with 27 being most severe (worse). | ClinicalTrials.gov |
| Secondary | Physician Well-Being Index (PWBI) | 180 days | The Physician Well Being Index is a 7 question survey, scored 0-7, with lower scores indicative of better physician well being. | ClinicalTrials.gov |
