Three flooring materials, terrazzo, rubber, and carpet tile, in patient unit corridors were compared for absorption of sound, comfort, light reflectance, employee perceptions and preferences, and patient satisfaction.
Environmental stressors, such as noise and ergonomic factors, effect healthcare workers and patients, contributing to increased fatigue, anxiety and stress, decreased productivity, and patient safety and satisfaction.
A longitudinal comparative cohort study comparing three types of flooring assessed sound levels, healthcare worker responses, and patient Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) ratings over 42 weeks. A linear mixed model analysis was conducted to determine significant differences between the means for participant responses and objective sound meter data during all three phases of the study.
A significant difference was found for sound levels between flooring type for equivalent continuous sound levels. Carpet tile performed better for sound attenuation by absorption, reducing sound levels 3.14 dBA. Preferences for flooring materials changed over the course of the study. The HCAHPS ratings aligned with the sound meter data showing that patients perceived the noise levels to be lower with carpet tiles, improving patient satisfaction ratings.
Perceptions for healthcare staff and patients were aligned with the sound meter data. Carpet tile provides sound absorption that affects sound levels and influences occupant's perceptions of environmental factors that contribute to the quality of the indoor environment. Flooring that provides comfort underfoot, easy cleanability, and sound absorption influence healthcare worker job satisfaction and patient satisfaction with their patient experience.
比较患者单元走廊中的三种地板材料——水磨石、橡胶和地毯砖——在吸音、舒适度、光反射、员工感知和偏好以及患者满意度方面的性能。
环境压力源，如噪音和人体工程学因素，会影响医护人员和患者，导致疲劳、焦虑和压力增加，生产力下降，以及患者安全和满意度降低。
一项比较三种地板类型的纵向对比队列研究，评估了 42 周内的声音水平、医护人员的反应以及患者对医疗保健提供者和系统的医院消费者评估（HCAHPS）的评分。采用线性混合模型分析来确定参与者反应和客观声级计数据在研究的所有三个阶段之间的平均值之间的显著差异。
在等效连续声级方面，地板类型之间的声音水平存在显著差异。地毯砖在吸音方面表现更好，可将声音降低 3.14 dBA。随着研究的进行，对地板材料的偏好发生了变化。HCAHPS 的评分与声级计数据一致，表明患者认为地毯砖的噪音水平较低，从而提高了患者的满意度评分。
医护人员和患者的感知与声级计数据一致。地毯砖提供吸音效果，影响声音水平，并影响居住者对室内环境质量有影响的环境因素的感知。提供舒适感、易于清洁和吸音效果的地板会影响医护人员的工作满意度和患者对其就医体验的满意度。
