Effects of environmental changes on conditions of staff and patients in the new hospital

以某大学医院为例，探讨了环境变化对医院职工和病人的影响。调查了新旧病区患者和护士对医院设施设备环境的主观评价。测量了空气条件、照度和声级。结果，在新病房中发现了许多改进。主要问题是吸烟角、电梯、单人间的空调条件，后来有所改善，需要重新评估。我们观察了在新病房活动开始之前和之后甲醛浓度的变化。在开始前测量了高浓度。开始时，通过病房通风系统降低浓度。使用气相色谱-质谱（TurboMass, PerkinElmer）和热解吸（ATD400, PerkinElmer）系统对新旧病房的气体样品进行分析，发现挥发性有机化合物含量差异不大。三甲基苯高值的背景有待进一步研究。横断面研究结果显示，老病区护士抑郁自评量表得分高于新病区。然而，还需要进一步的研究。

In the term of reconstruction of a university hospital, effects of environmental changes on conditions of staff and patients were investigated.1.Subjective assessment of hospital environment concerning to facilities and equipment by patients and nurses were investigated in new and old wards. Air conditions, illuminance, and sound level were measured. In result, many improvements in new wards were found. Main problems were air conditions concerning to smoking corner, elevators, and single rooms, which were improved later and should be reevaluated.2.We observed the changes in formaldehyde concentrations just before and after the start of the new ward activity. High concentrations were measured just before the start. At the start, the concentrations were lowered by ventilation system of the ward.3.The analysis of gas samples using gas chromatograph mass spectrometry (TurboMass, PerkinElmer) and thermal desorption (ATD400, PerkinElmer) system demonstrated little difference between the volatile organic compounds levels in new and old wards. The background of the high values of trimethyl-benzene should be further studied.4.In results of a cross-sectional study, the score of Self-Rating Depression Scale of nurses in old wards was higher than in new wards. However, further studies are neccessary.
