Sufficient sleep quality easily measured: a multicenter centre study in dutch ICUS

Introduction Sleep is a fundamental need for recovery while a lack of good sleep is associated with adverse effects. ICU patients have an increased risk for disturbed sleep. Various sleeping questionnaires have been developed to assess the different aspects of sleep. The Richards Campbell Sleep Questionnaire (RCSQ) is one of the most commonly used sleep assessment tools for the ICU consisting of 5 questions on different aspects of sleep and reasons for poor sleep. However, it seems irrelevant to burden patients that state to have a good night sleep with the complete RCSQ. For clinical and developmental use it is useful to quantify sleep in a simple and effective manner. Therefore, the aim of our study was to investigate a simple sleeping numeric rating score; NRS sleep.
