View on ClinicalTrials.gov →
Summary
The goal of the trial is to learn if a strategy to eliminate audible alarm noise in intensive care and high dependency units can reduce overall noise levels, patient delirium, staff alarm fatigue, and staff burnout. Researchers will implement a silent alarm strategy in specific care units for four weeks and compare this to a separate 4 weeks where a silent strategy is not implemented. Noise, burnout, delirium levels, and staff alarm response times will be compared between the silent and non-silent units.
