Noise and light are frequently cited as major factors contributing to sleep disturbance. The paediatric intensive care unit (PICU) layout may increase environmental stimuli and limit nurses' control over the environmental disturbances that patients encounter.
This study aims to describe nurses' perceptions regarding the layout of the PICU and its potential impact on environmental disturbances and patients' sleep. Additionally, it seeks to investigate the extent to which unit layout impacts environmental disturbances across Scandinavian countries.
A comparative cross-sectional study was conducted using an online questionnaire in three PICUs in three large university hospitals in Norway, Sweden and Denmark.
Out of the 79 study participants, 63% did not agree that their PICU layout was conducive to their patients sleeping well. While 52% reported having control over the light at nighttime, 55% felt that they were unable to control noise levels during the night. Monitors and alarms were rated as the highest contributing factors limiting control over noise. Compared to the Danish nurses, the Norwegian nurses were five times less likely to agree that the unit layout supported a normal sleep-wake cycle.
The Scandinavian nurses perceived the PICU layouts as inadequate for promoting control over the environment and patients' sleep. The Norwegian PICU layout, with larger multibed units, was perceived as inferior in promoting sleep and controlling noise and light compared with the Swedish and Danish PICUs.
This study provides valuable insights to nurses regarding the specific factors influencing noise and light in the PICU, enabling nurses to take appropriate measures to improve sleep by gaining control over the patient's environment. Additionally, the results of this study can inform future renovations or modifications of multibed units, with the aim of preventing the layout from restricting nurses' control over the noise and light levels experienced by patients.
噪音和光线常被认为是导致睡眠障碍的主要因素。儿科重症监护病房（PICU）的布局可能会增加环境刺激，并限制护士对患者所面临的环境干扰的控制。
本研究旨在描述护士对PICU布局及其对环境干扰和患者睡眠的潜在影响的看法。此外，它还试图调查病房布局在斯堪的纳维亚国家对环境干扰的影响程度。
在挪威、瑞典和丹麦的三家大型大学医院的三个PICU中使用在线问卷进行了一项比较横断面研究。
在79名研究参与者中，63%不同意他们所在的PICU布局有利于患者良好睡眠。虽然52%的人报告说在夜间能够控制灯光，但55%的人觉得他们在夜间无法控制噪音水平。监测器和警报被评为限制噪音控制的最大因素。与丹麦护士相比，挪威护士认为病房布局支持正常睡眠 - 觉醒周期的可能性要低五倍。
斯堪的纳维亚护士认为PICU布局不足以促进对环境和患者睡眠进行控制。与瑞典和丹麦的PICU相比，拥有较大多床位病房的挪威PICU布局在促进睡眠以及控制噪音和光线方面被认为较差。
本研究为护士提供了关于影响PICU噪音和光线的具体因素的宝贵见解，使护士能够通过控制患者环境采取适当措施来改善睡眠。此外，本研究结果可为未来多床位病房的翻新或改造提供参考，以防止布局限制护士对患者所经历的噪音和光线水平的控制。
