Importance Extended work hours and night shifts are essential in health care, but negatively affect physician sleep, well-being, patient care. Alternative schedules with shorter and/or reduced irregularity might mitigate these issues. Objective To compare cognition between interns working irregular, extended (call schedule), those a more regular schedule restricted (float schedule). Design, Setting, Participants In this observational longitudinal cohort study, Singapore-based teaching hospital were studied for 8 weeks from January 2022 to July 2023. Data analyzed 2023 2024. Exposure worked either approximately 10-hour workdays, interspersed 24 hour or overnight calls 4 5 times month, float schedule, which included 7 consecutive 12-hour every 2 months. was based on departmental training operational needs. Main Outcomes Measures Sleep measured wearable sleep trackers an electronic diary. Day-to-day well-being cognitive assessments collected through smartphone application. Assessments the Regularity Index (SRI; determines probability of individual being same state [sleep wake] at any time points apart, 0 indicating highly random patterns 100 denoting perfect regularity) Pittsburgh Quality Inventory (PSQI; scores ranges 21, higher poorer sleep; score greater than suggests significant difficulties). Results (mean [SD] age, 24.7 [1.1] years; 57 female participants [59.4%]; 41 call [42.7%]; 55 [57.3%]) provided 4808 nights (84.2%) 3390 days (59.3%) assessments. had SRI score, 69.4 [6.16]) better quality (PSQI mean 5.4 [2.3]), (SRI 56.1 [11.3]; t 91 = 6.81; difference, 13.3; 95% CI, 9.40 17.22; P < .001; PSQI 6.5 [2.3]; 79 2.16; 0.09 2.15; .03).
