ICU sedation, delirium & recovery
Based -evidence, an intervention study to improve sleep quality in awake adult intensive care unit (ICU) patients: a prospective, single-blind, clustered controlled trial
Authors' conclusion
Evidence-based interventions significantly improve sleep quality in ICU patients hospitalized for more than one day. However, our results do not support the improvement of sleep quality in patients admitted to the ICU for one day.
Study context
- Population
- Conscious adults (≥18 years) staying ≥1 night in two intensive care units (ICUs) of a tertiary teaching hospital in Chinaincluded in the analysis
- Participants
