Sleep Bundle for Improving Sleep in ICU Patients

Summary of the project : Lack or disturbances of sleep are major problems in patients staying in intensive care unit (ICU) due to the particular environment. The noises, lack of circadian rhythm of light lead to progressive deafferentation. The patients are then at risk of immune deficiencies, agitation and confusion states, cognitive troubles that may be associated to increased morbidity and mortality in the short and long term. Thus, improvement of the sleep of the ICU patients may impact non only during the ICU stay but also on their future quality of life. The sleep bundle project is a quality improvement project with a before-after design, consisting in the evaluation of a bundle of measures that may increase the quality and duration of sleep in ICU patients. The bundle consists in the proposition of eye-mask, ear-plugs, music and/or massage to the patients in parallele to structural and organizational modifications of the service such as the decrease of the alarms sounds, changing the luminosity between day and night, etc. The principal indicators followed will be: * The sleep quality of the patients * The continuous noise intensity in the rooms * The continuous light intensity in the rooms Baseline - before period: 8 weeks Implementation of the bundle with training of the team: 4 weeks After period: 8 weeks.
