The implementation of a noise reduction bundle in the intensive care unit: A qualitative process evaluation

This process evaluation of the randomized clinical trial investigating a bundle of noise-reducing interventions, demonstrates that successful ICU noise reduction requires a structured implementation and attention to contextual and cultural factors. While engaged leadership and feedback facilitated adoption, a limited sense of urgency and the absence of shared noise norms impeded sustainability. An integrated approach-combining technical solutions with behavioral strategies, and promoting team ownership and open communication-is essential.
