Effects of workload on residents'sleep duration : objective documentation.
Sleep-wake cycles of 27 residents from the 800-bed Rambam hospital, which serves the northern part of Israel, were investigated by wrist-worn actigraphs.
Fifteen subjects (aged 30.6±4.6) worked in wards with a « heavy » workload, and 12 (aged 35±2.6) in wards with a « light » load.
There were significant differences among the residents in sleep duration.
Residents working in the emergency room had the shortest sleep periods, and those working in « light » wards had the longest.
There was no significant increase in sleep duration the day after the night « on call. » Sleep duration was significantly negatively correlated with the number of new admissions, and with the subjective daily assessment of work load.
It is concluded that residents working in wards with a heavy load suffer from chronic partial sleep deprivation, which should be taken into consideration in residents'work regulation.
