Randomized Controlled Trial Clinical Trial
Effects of critical care unit noise on the subjective quality of sleep.
Nurse researchers have provided evidence that hospital critical care unit (CCU) noise may put patients at risk for sleep problems. Technological advances in this setting have been described as contributing to this problem. Although data on the negative effects of CCU noise on physiological sleep are available, less attention has been given to self-reports of the subjective quality of sleep following exposure to this stressor. ⋯ Data on the quality of dreams yielded no difference between groups. The results provide support for the hypothesis that CCU sound levels impact negatively on subjective sleep. It was recommended, now that CCU sound levels were isolated in the laboratory as a potential stressor, that future research should attempt to replicate this study in a hospital CCU.
