DOI : 10.23893/1307-2080.APS.05515 The aim of present study was to determine the quality of indoor air of different wards of three hospitals in Lahore to check the atmosphere of these hospitals might be a potential source of hospital acquired infections. Using Buck?s biological air sampler, microbiological samples were collected from different units of three hospitals. The average amount of microbial loads was determined by using colony counter (Suntex, CC-570). The present study showed that bacterial population was increased in Out Patient Department (75.89%), Intensive Care Unit (78.43%) and Nursery Unit (81.5%) statistically significant in three hospitals at evening time. The bacteria isolates were Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumonia and Escherichia coli. It was found that indoor air quality of the three hospitals varied depending on disinfection process frequency and number of individuals present in environment. The average number of microorganisms in the atmosphere of hospitals did not fulfill the maximum allowed colony forming units per cubic meter.
