In many countries, healthcare workers make up the single largest proportion of shift workers 1– 3. Although healthcare workers perceive themselves to be less alert on the first night shift compared to subsequent night shifts, objective performance is equally impaired on subsequent nights. Alertness and performance remain most impaired during night shifts given the lack of circadian adaptation to night work. In rotating shift workers, early day shifts can be associated with similar sleep restriction to night shifts, particularly when scheduled immediately following an evening shift. On nights, working during the circadian acrophase of the urinary melatonin rhythm led to poorer outcomes on the KSS and PVT. KSS and PVT mean reaction times were higher at the end of the first and subsequent night shift compared to day shift, with KSS highest at the end of the first night. Sleep was most restricted between consecutive night shifts (5.74 ± 1.30 h), consecutive day shifts (5.83 ± 0.92 h) and between evening and day shifts (5.20 ± 0.90 h). Circadian phase was assessed using urinary 6-sulphatoxymelatonin rhythms. Subjective sleepiness (Karolinska Sleepiness Scale, KSS) and Psychomotor Vigilance Test (PVT) performance were examined during day shift, and on the first and subsequent night shifts (3 rd, 4 th or 5 th). Sleep and wake duration between shifts were evaluated using wrist actigraphs and diaries. This study examined sleep between shift types (day, evening, night), and alertness and performance during day and night shifts in 52 intensive care workers. Shift work is associated with impaired alertness and performance due to sleep loss and circadian misalignment.
