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.
