Abstract

Hospital soundscapes can be difficult environments to assess acoustically due to alarms, medical equipment, and the continuous activity within units. Routinely, patients perceive these soundscapes to be poor when rating their hospital experience on HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) surveys administered after discharge. In this study, five hospital units of widely varying HCAHPS "quietness" performance were analyzed. Sound pressure levels were measured in 15 patient rooms and 5 nursing stations over 24-h periods. HCAHPS "quietness of the hospital environment" patient survey data were correlated with measured acoustical data at a room-level, revealing acoustical metrics linked to patient perceptions of hospital soundscape conditions. Metrics found to be statistically correlated (p < 0.05) included the absolute LA levels in patient rooms, which found significantly higher HCAHPS quietness scores in units with average LA levels below 35 dBA, in addition to specific low frequency octave bands and occurrence rates. Many other standard acoustical metrics (such as LA, LA, LC, and LA) were not found to be statistically correlated between measured acoustical data and HCAHPS quietness patient responses. Taken as a whole, this study provides insights into the potential relationships between hospital noise and patient satisfaction.

摘要

医院的声景观由于警报声、医疗设备和病房内持续的活动，使得声学评估变得复杂。通常情况下，患者在出院后接受 HCAHPS（医院消费者评估医疗保健提供者和系统）调查时，会对其住院体验进行评价，他们会认为这些声景观较差。在这项研究中，分析了五个具有广泛不同 HCAHPS“安静度”性能的医院病房。在 24 小时内，对 15 个病房和 5 个护士站进行了声压级测量。HCAHPS“医院环境安静度”患者调查数据与房间级别的测量声学数据相关联，揭示了与患者对医院声景观条件的感知相关的声学指标。发现具有统计学相关性（p < 0.05）的指标包括病房内的绝对 LA 水平，在平均 LA 水平低于 35 dBA 的病房中，HCAHPS 安静度评分显著更高，此外还包括特定的低频倍频带和出现率。许多其他标准声学指标（如 LA、LA、LC 和 LA）在测量的声学数据和 HCAHPS 安静度患者反应之间未发现具有统计学相关性。总的来说，这项研究提供了有关医院噪声与患者满意度之间潜在关系的见解。
