In general, sleeping and activity patterns vary between individuals. This attribute, known as chronotype, may affect night shift performance. the intensive care unit (ICR), performance impact patient safety. We have investigated effect of chronotype social demographics on sleepiness, fatigue, nurses. was a prospective observational cohort study which assessed 96 ICU nurses during day shifts in mixed medical–surgical Netherlands. determined behaviour for each nurse prior to starting work before free days. The level sleepiness fatigue determined, these conditions psychomotor vigilance mathematical problem-solving. majority had preference early (morning chronotype). Compared their counterparts (i.e. evening chronotypes), they were more likely nap commencing young children living at home. Despite increased shifts, no observed shifts. Problem-solving accuracy remained high cost productivity. Most here appeared adapted well work, despite percentage morning chronotypes, possibly due 8-h duration. Parental responsibilities may, however, influence tolerance.
