Sounds in intensive care units: Perspectives of patients and parents. A qualitative study Abstract: Background: Sound levels in intensive care units exceed internationally recommended limits. This can have negative effects on patients, relatives, and staff. There is a lack of evidence on noise-reducing measures. Aim: The aim of the study was the implementation and evaluation of ward-specific noise management in intensive care units. In the present article, the question of the noise and stress experience of intensive care patients and parents of neonatal intensive care patients was explored. Methods: 33 semi-structured interviews with intensive care patients and parents of neonatal intensive care patients in three intensive care units were conducted and analysed. Results: Sounds in intensive care units can be stressful (especially alarms) but also be interpreted as meaningful. This is not only related to the context of the ICU, but also to individual experiences and the social aspects of the sounds. In order to avoid or reduce stress, participants apply individual noise (stress) management. In contrast, ward-related noise management had no specific effect on the participants. Conclusions: The findings offer indications for suitable measures to reduce the noise exposure of intensive care patients and parents of neonatal intensive care patients. Research about measures such as concepts for supporting the attribution and differentiation of sounds could follow.

Noise exposure among staff in intensive care units and the effects of unit-based noise management: a monocentric prospective longitudinal study.

BACKGROUND: Intensive care units (ICUs) are often too noisy, exceeding 70-80 dBA, which can have negative effects on staff. The corresponding recommendation of the World Health Organization (average sound pressure level below 35 dBA) is often not achieved. To date there is a lack of intervention studies examining the extent to which unit-based noise management in ICUs contributes to a reduction in noise exposure for the staff. The study therefore aims to provide answers to 1) how unit-based noise management sustainably reduces the subjective noise exposure among staff, and 2) how this intervention affects other noise-related topics. METHODS: We performed a monocentric prospective longitudinal study with three measurement points in a German university hospital in three ICUs. We collected data from different healthcare professionals and other professional groups between October 2021 and August 2022 using an online questionnaire. Data were analyzed using descriptive and inference statistics. RESULTS: A total of n = 179 participants took part in the surveys. The majority of participants were nurses or pediatric nurses. Most participants worked more than 75% full-time equivalent. Staff on the three ICUs reported high levels of noise exposure. No significant changes in noise exposure over time were observed. Participants were already aware of the topic and believed that a behavior change could positively influence the noise environment. CONCLUSIONS: This study provides an initial insight into how a unit-based noise management could contribute to a reduction in the subjective noise exposure among staff in ICUs. The results of this study highlight the importance of this topic. Future studies should aim to research aspects of adherence and their facilitators or barriers, which promote the sustained implementation of noise-reducing measures by staff.
