Persico N, et al. - This study was undertaken to assess the cognitive performance of emergency physicians after a night shift of 14 hours (H14) and after a work shift of 24 hours (H24) and to compare it with tests performed after a rest night at home (H0). Researchers observed that the cognitive abilities of emergency physicians after a 24-hour shift were significantly altered, however, after a 14-hour night shift, these were not significantly different from the rested condition. They recommended considering and further evaluation of limiting 24-hour shift work for emergency physicians.
