Sounds in intensive care units: Perspectives of patients and parents. A qualitative study

Abstract

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.
