Do Sleep Disorders have an Impact on Outcome in ICU Patients?
The intensive care unit (ICU) setting represents a hostile environment for mechanically ventilated patients. Although considerable efforts have been undertaken to continuously improve the outcomes of ICU patients) overall morbidity and mortality have not been dramatically reduced during the past 20 years. The role of factors that have previously been considered as having a negligible impact on outcome needs to be revisited. Several lines of evidence suggest that sleep is qualitatively and quantitatively severely disturbed in ICU mechanically ventilated patients. Hence) sleep disturbances, as estimated using sleep-quality questionnaires) affect a very high percentage of patients) and persist for many days) even for several weeks or months in some cases) after anesthesia and intensive care. Sleep disorders may play an unexpectedly important role in decreasing host defenses and in worsening patient outcome. The importance of sleep disorders in the ICU has been recently emphasized in elegant reviews on the topic [1, 2]. In the present chapter) we will focus on the possible impact of these disorders on outcomes in ICU patients) and suggest possible ways to improve sleep quality in the ICU.
