ICU sedation, delirium & recovery
Evaluation of the sensory environment in a large tertiary ICU
Authors' conclusion
This study corroborates other studies confirming that the lighting and acoustic environments in the study ICU were suboptimal, potentially contributing to adverse patient outcomes.
Study context
- Population
- Selected bedspaces representing different bedspace types in a large tertiary ICU
- Participants
- 3 monitored bedspaces
- Outcome
- Lighting and acoustic environment
Methodological detailssensor-based monitoring, descriptive analysis
- Sensor-based monitoring
- Descriptive analysis
Main finding
As reported in the abstract
- Average daytime light intensity in 2 of 3 bedspaces
- not exceeding 300 Lux
- Average sound levels in study bedspaces (single room noisier than 2 open-plan bedspaces)
- 63.75, 56.80, and 59.71 dBA
- Multiple peak sound levels
- > 80 dBA
- Maximum sound level recorded
- > 105 dBA
- New monitor or ventilator alarm commencing in each bedspace
- every 69 s
- Alarms actioned
- 5%
Observational data: associations, not effects.
