MONITORING THE AIR MICROBIOLOGIC QUALITY IN HEALTH CARE UNITS

摘要

Environmental monitoring is imperative in health care units. The aim of this study is to give a characterization for the level of air contamination in different departments of a county hospital, under a variety of normally encountered conditions. Furthermore we want to discuss some requirements for a monitoring system in Romanian hospitals. Based on 768 samples, the mean bacterial count from air ranged from 22CFU/m~3 in operating rooms to 3149 CFU/m~3 in patient rooms; 34% from all samples exceeds the national target of total bacteria, 32.2% of samples were gram-positive cocci and from these 15.5% were hemolytic. In conclusion, the hospital airborne contamination was greater than expected, and it was influenced by human activity, ventilation considerations, and gross surface contamination.
