Background

This is a survey to understand sleep in the context of medical trainees (on call) and the participants knowledge about the relevance of sleep, shiftwork, and the impact that sleep may have on their working performance. The survey has been developed by sleep experts from America, Europe, and Africa, in collaboration with the World Sleep Society. It should take about 30-40 minutes to complete.

    Composite outcome as described by deviation from regular sleep in terms of sleep quality (points, out of 10; higher scores indicating more symptoms), quantity (duration, hours:mins), and deviation from circadian rhythm (measured in times of the day and duration, as well as perceived disturbance, points out of 10; higher points indicating more symptoms)

Secondary outcomes

    Basic demographics, family status/children

  2. Sleep routine

    Sleep routine while ON CALL / not ON CALL (bed time, hours:mins; wake up time, hours:mins)

  3. Epworth Sleepiness Scale

    Time frame: within 3 months of completion

    Validated screening questionnaire containing eight questions related to likelihood of dozing (min score 0, max score 24 points; higher scores indicate more symptoms)

  4. Insomnia Severity Index

    Time frame: within 3 months of completion

    Validated questionnaire assessing likelihood of insomnia (7 questions, min 0 / max 28 points; higher scores indicate more symptoms)

  5. Basic knowledge and perception of sleep

    Time frame: within 3 months of completion of survey

    Impact of work/on call on sleep (duration of sleep, hours:mins; sleep quality, points out of 10; symptoms, points out of 10; higher scores indicating more symptoms)
