To investigate the differences and relationships between different outdoor spaces of hospitals on the physiological electroencephalography (EEG) feedback (PEEGF) of staff.
Relieving the pressure of hospital staff is essential, and several studies have revealed that even short-term exposure to outdoor space has a decompression effect. Yet, the focus is scarcely centered on the differences and influential relationships between the PEEGF from different outdoor spaces where the staff spend time, particularly in large-scale hospitals in China.
EEG measurement equipment was utilized to obtain the value of β wave (vβw) that represents the stress and anxiety of staff in three different outdoor spaces: open, traffic, and rest. On the basis of EEG data, correlation analysis was conducted in accordance with the proportion of space elements.
The proportion of natural elements, such as landscape ( = -.800** p=.005) and waterscape ( = -.782* p=.013), were negatively correlated with the vβw produced by staff, while the proportion of hard paving was positive ( = .817** p=.004) with more vβw produced by staff. In other words, the percentage of landscape and waterscape can reduce stress, while hard paving has the opposite effect. Further, there was a difference in the amount of vβw generated between nurses and administrators in the open space at the entrance of the main building ( = .043).
The present study revealed the influence of different outdoor space elements of the hospital on the physiological feedback of staff, demonstrated the practical necessity of evidence-based design, and proposed relevant optimization suggestions.
探讨医院不同户外空间对工作人员生理脑电图反馈（PEEGF）的差异及关系。
缓解医院工作人员的压力至关重要，多项研究表明，即使短期接触户外空间也有减压效果。然而，很少有人关注工作人员花费时间的不同户外空间的PEEGF之间的差异和影响关系，尤其是在中国的大型医院。
利用脑电图测量设备获取代表工作人员在三种不同户外空间（开放空间、交通空间和休息空间）的压力和焦虑的β波值（vβw）。基于脑电图数据，根据空间元素比例进行相关分析。
景观（r = -0.800**，p = 0.005）和水景（r = -0.782*，p = 0.013）等自然元素的比例与工作人员产生的vβw呈负相关，而硬质铺装的比例则呈正相关（r = 0.817**，p = 0.004），即工作人员产生的vβw更多。换句话说，景观和水景的比例可以减轻压力，而硬质铺装则有相反的效果。此外，在主楼入口处的开放空间中，护士和管理人员产生的vβw量存在差异（p = 0.043）。
本研究揭示了医院不同户外空间元素对工作人员生理反馈的影响，证明了循证设计的实际必要性，并提出了相关优化建议。
