摘　　要：目的医院室内空气质量直接影响院内每个人的身体健康。本研究旨在调查上海市普陀区医疗机构候诊区域空气质量状况,为医院传染病的预防和控制提供参考依据。方法在2018年对上海市普陀区19家医疗机构候诊区域的空气质量进行检测。比较不同候诊区域、不同通风方式及不同时段空气质量的差异,以(均值±标准差)描述检测指标的水平,运用单因素方差分析检验是否有统计学差异。结果医院候诊区CO浓度最高(0.600±0.096)、候诊大厅次之(0.539±0.108)、输液室最低(0.516±0.100);自然通风的PM10浓度(0.044±0.021vs.0.037±0.014,P=0.019)和PM2.5浓度(0.028±0.008vs.0.024±0.008,P=0.010)显著高于机械通风;上午CO2浓度(0.079±0.015vs.0.073±0.010,P=0.019)和空气细菌总数(8.421±7.058vs.5.684±3.561,P=0.010)均显著高于下午。结论建议加强医院候诊区及上午就诊时间段的空气质量管理,优化通风系统。Objective Hospital indoor air quality directly affects everyone’s health in the hospital. This study aimed to investigate the air quality in waiting areas of medical institutions in Putuo District, in order to provide reference basis for the prevention and control of hospital infection. Methods The air quality of 19 waiting areas of medical institutions in Putuo District was tested on June 15, 2018. The differences of air quality in different waiting areas, different ventilation modes and different periods were compared.(Mean ± SD)was used to describe the level of test indicators, and one-way ANOVA to test whether there were statistical differences between different groups. Results CO in waiting area was the highest (0.600±0.096), followed by waiting hall (0.539±0.108). Infusion room was the lowest (0.516±0.100). PM10 (0.044±0.021 vs. 0.037±0.014, P= 0.019) and PM2.5 (0.028±0.008 vs. 0.024±0.008, P=0.010) in natural ventilation were significantly higher compared with mechanical ventilation. CO2 (0.079±0.015 vs. 0.073±0.010, P = 0.019) and total bacterial count (8.421±7.058 vs. 5.684±3.561, P=0.010) in the morning was significantly higher than those in the afternoon. Conclusions It was suggested to strengthen air quality management in hospital waiting area and morning visiting period,as well as to optimize ventilation system.
