Les objectifs de cette étude étaient d’explorer les niveaux de fatigue et les mesures du sommeil des infirmières pendant deux quarts de jour consécutifs de 12 heures et d’examiner les relations entre les niveaux de fatigue des infirmières pendant les quarts et les caractéristiques de leur sommeil la nuit précédente.
OBJECTIVE The aims of this study were to explore nurses’ fatigue levels and sleep measures during two 12-hour consecutive day shifts and examine the relationships between nurses’ fatigue levels within shifts and their previous-night sleep characteristics. BACKGROUND Monitoring changes in fatigue and sleep is important to enable effective fatigue management. METHODS This was a descriptive, repeated-measures study. Data were collected using surveys and actigraphy 4 times during each consecutive shift (7:00 am-7:30 pm). RESULTS General fatigue levels started trending up 4 hours after the start of work; highest levels were reported at 7:30 pm. Fatigue levels accumulated across consecutive shifts. Subjective sleep quality was higher the night before the 2nd shift than the night before the 1st shift. Nurses’ poor sleep the night before a shift was related to increased fatigue levels during the next shift. CONCLUSION It is important to consider when fatigue management interventions will be most effective and to consider previous-night’s sleep when monitoring fatigue.
