Design outcomes

Primary

MeasureTime frame
Sleep monitor variables: 1. Sleep duration (total sleep time) for the primary sleep period is objectively measured daily by a sleep monitor (Somnofy) for 2 months 2. Time in light sleep for the primary sleep period is objectively measured daily by a sleep monitor (Somnofy) for 2 months 3. Time in deep sleep for the primary sleep period is objectively measured daily by a sleep monitor (Somnofy) for 2 months 4. Time in rapid eye movement(REM)-sleep for the primary sleep period is objectively measured daily by a sleep monitor (Somnofy) for 2 months

Secondary

MeasureTime frame
Sleep monitor variables: 1. Sleep onset latency (the duration of time from turning the light off to falling asleep) for the primary sleep period is objectively measured daily by a sleep monitor (Somnofy) for 2 months. 2. Wake after sleep onset (time spent awake after falling asleep) for the primary sleep period is objectively measured daily by a sleep monitor (Somnofy) for 2 months. 3. Sleep efficiency (total sleep time/time in bed) for the primary sleep period is objectively measured daily by a sleep monitor (Somnofy) for 2 months. Register data variables: 4. Sickness absence (number of days and number of spells) is measured by register data (the hospital's day-to-day registration of participants’ working hours and sick leave) over the 2-month sleep registration period. Questionnaire data variables: 5. Turnover intention is measured using the Turnover Intention Scale (TIS) at 2-month follow-up. 6. Psychological detachment is measured using the relevant scale from the Recovery Experience Questionnaire (REQ) at 2-month follow-up. 7. Patient-related burnout is measured using the relevant scale from the Copenhagen Burnout Inventory (CBI) at 2-month follow-up. 8. Work-related negative incidents (e.g. dozing off at work, causing harm to patients/others) are measured using a reduced version of the work-related negative incidents questionnaire at 2-month follow-up. 9. Self-reported medication errors (e.g. administered wrong drug dosage, administered drug to wrong patient) at the workplace are measured using self-developed questions at 2-month follow-up. 10. Self-reported injuries (e.g. needlestick or sharp objects) at the workplace are measured using self-developed questions at 2-month follow-up. 11. Self-reported exposure to hazardous chemicals (e.g. chemotherapy) at the workplace is measured using self-developed questions at 2-month follow-up. 12. Self-reported threats/violence (e.g. verbal threats) at the workplace is measured using self-developed questions at 2-month
