PURPOSE: Sleep deprivation is a common problem in healthcare workers. Sleepiness in nurses has important implications for patient and nurse safety. We have previously shown that night-shift nurses have pathologic sleepiness as measured by MSLT. We wished to objectively measure total sleep quantity by actigraphy in nurses in day- and night-shifts to see if this correlated with work-time sleepiness.
METHODS: Night shift and day-shift RNs in ICU were assessed using actigraphy worn for seven days. Subjective sleepiness was assessed by Epworth sleepiness scores (ESS). Nurses also answered questions related to the effects of sleepiness.
RESULTS: 10 day-shift RNs and 9 night-shift RNs completed the study. Mean age groups were similar between groups (table 1). Mean sleep quantity per night were not different between day-shift RNs and night-shift RNs. Despite of an equivalent amount of sleep, ESS was abnormal (>10) in 7 of 9 night-shift nurses compared to 2 out of 10 day-shift nurses (p = 0.017). Mean ESS scores were higher in the night-shift group (table 1). Nine out of nineteen nurses admitted to feeling sleepy while driving home after the shift.
CONCLUSION: There is no difference in average sleep quantity in nurses in day-shift and night-shift. Despite this night-shift nurses experience more work-time sleepiness than day-shift nurses.
CLINICAL IMPLICATIONS: Sleep deprivation is a common problem in healthcare workers. Measures solely aimed at increasing sleep-time in night-shift nurses may not alleviate their functional status.
