The introduction of a sound reduction bundle in the intensive care unit and its impact on sound levels and patients

Abstract

The interventions did not lead to a sound-level reduction; however, there was a large reduction in ICU monitor alarms without any alarm-related adverse events. As the sources of sound are diverse, multidimensional interventions, including staff education, alarm management solutions, and environmental redesign, are likely to be required to achieve a relevant, lasting, and significant sound reduction.
