The effectiveness of environmental strategies on noise reduction in a pediatric intensive care unit: Creation of single‐patient bedrooms and reducing noise sources

PURPOSE: Noise is a substantial problem for both patients and healthcare workers in hospitals. This study aimed to determine the effectiveness of environmental strategies (creating single-patient rooms and reducing noise sources) in noise reduction in a pediatric intensive care unit. DESIGN AND METHODS: Noise measurement in the unit was conducted in two phases. In the first phase, measurements aimed at determining the unit's present level of noise were performed over 4 weeks in December 2013. During the month following the first measurement phase, the intensive care unit (ICU) was moved to a new location and noise-reducing strategies were implemented. The second phase, in May 2014, measured noise levels in the newly constructed environment. RESULTS: The noise levels before and after environmental changes were statistically significant at 72.6 dB-A and 56 dB-A, respectively (p < .05). PRACTICE IMPLICATIONS: Single-patient rooms and noise-reducing strategies can be effective in controlling environmental noise in the ICU.
