Poor indoor air quality in healthcare settings has been tied with the increase in hospital-acquired infections. Thus, this systematic review was conducted to assess the levels and compositions of bacteria in indoor hospital air in the Middle East and North Africa (MENA) region. We examined results provided by different search engines published between 2000 and 2021. Our data showed that most studies were conducted in Iran (80.9%) with a bacterial concentration mean of 172.9 CFU/m. Comparing sensitive and non-sensitive areas of hospitals, no significant difference was detected in the mean bacterial concentration. The most investigated sensitive hospital areas were operating rooms and intensive care units with mean indoor bacterial concentrations of 180.3 CFU/m and 204.6 CFU/m, respectively. , , , and were commonly identified bacterial families. In conclusion, the mean concentrations of the airborne bacteria were within the acceptable limit compared to WHO standards (300 CFU/m) for the air in areas occupied by immunosuppressed people.
医疗机构室内空气质量差与医院获得性感染的增加有关。因此，开展了这项系统评价，以评估中东和北非（MENA）地区医院室内空气中细菌的水平和组成。我们研究了2000年至2021年间不同搜索引擎提供的结果。我们的数据显示，大多数研究在伊朗进行（80.9%），细菌浓度平均值为172.9 CFU/m。比较医院的敏感区域和非敏感区域，未检测到平均细菌浓度有显著差异。研究最多的医院敏感区域是手术室和重症监护病房，室内细菌平均浓度分别为180.3 CFU/m和204.6 CFU/m。 、 、 和 是常见的细菌科。总之，与世界卫生组织针对免疫抑制人群居住区域空气的标准（300 CFU/m）相比，空气中细菌的平均浓度在可接受范围内。
