Reduction of sound levels in the intermediate care unit; a quasi-experimental time-series design study.

Objectives: This study aimed to assess the effectiveness of an architectural redesign and a multicomponent intervention bundle on noise reduction to enhance workplace safety.

Methods/design: Quasi-experimental study with a time-series and intensified intervention design conducted in an intermediate care unit. Two interventions were sequential introduced: the installation of a partition wall in the medication preparation room (architectural redesign) and the implementation of an a bundle.

The Effectiveness of the Interventions to Reduce Sound Levels in the ICU: A Systematic Review.

Unlabelled: Excessive noise is ubiquitous in the ICU, and there is growing evidence of the negative impact on work performance of caregivers. This study aims to determine the effectiveness of interventions to reduce noise in the ICU.

Data Sources: Databases of PubMed, EMBASE, PsychINFO, CINAHL, and Web of Science were systematically searched from inception to September 14, 2022.

Contribution of alarm noise to average sound pressure levels in the ICU: An observational cross-sectional study.

Objectives: To explore sound levels, alarm frequencies and the association between alarms and sound levels.

Design: A single center observational cross-sectional study.

Setting: Four intensive care units.
