Good ventilation is more important in hospitals than in many other buildings. The objective of this study was to evaluate the effect of the condition, performance and modernity of ventilation systems on the perceived indoor air quality (IAQ) and the indoor air-related symptoms of hospital personnel.
An inspection and evaluation graded on a 1 to 3 scale of the condition, performance, and modernity of the ventilation systems was carried out in ten central hospitals in Finland. The perceived IAQ and the related symptoms were collected by means of an indoor air questionnaire survey among the workers in these hospitals.
The condition, performance and modernity of the ventilation systems were good in 40% of the hospitals included in the research and poor in another 40% of them. In hospitals where the majority of the ventilation systems were assessed to be good, the prevalence of the indoor air-related complaints and symptoms was lower than in hospitals where the majority of the ventilation systems were assessed as needing extensive repairs.
The condition and performance of the ventilation systems in hospitals had a significant impact on the perceived IAQ and the symptoms observed among the employees in Finnish hospitals. Therefore, it is important that hospital ventilation systems are maintained properly and regularly. Furthermore, they should be renovated, at the latest when their technical lifespan expires.
良好的通风对于医院而言比其他许多建筑物更为重要。本研究旨在评估通风系统的状况、性能和现代化程度对医院人员感知的室内空气质量 (IAQ) 和与室内空气相关的症状的影响。
在芬兰的十所中心医院中，对通风系统的状况、性能和现代化程度进行了 1 到 3 分的检查和评估。通过在这些医院的工作人员中进行室内空气问卷调查，收集了感知的室内空气质量和相关症状数据。
在所研究的医院中，有 40%的通风系统状况、性能良好，另有 40%的通风系统状况较差。在大多数通风系统被评估为良好的医院中，与室内空气相关的投诉和症状的患病率低于大多数通风系统被评估需要广泛维修的医院。
医院通风系统的状况和性能对芬兰医院员工感知的室内空气质量和观察到的症状有重大影响。因此，适当且定期维护医院通风系统非常重要。此外，当通风系统的技术寿命到期时，应进行翻新。
