Airborne Microbial Risk Assessment in Indonesian Hospitals 2024: Control Strategies to Improve Environmental Quality

Abstract

Hospital is a place where healthy and sick people meet, therefore the air quality in the hospital needs to be considered because it can affect human health. One of the risks of exposure to indoor air bacteria is Mycobacterium tuberculosis in health workers who work in pulmonary services and have direct contact with Tuberculosis patients every day. The purpose of this study was to determine the magnitude of the risk of exposure to air germ numbers to the health of pulmonary clinic staff in the hospital.  The results obtained will be analysed using the Microbial Risk Assessment method. Based on the measurement of the air germ count in the pulmonary clinic room, the total germ count is 32 CFU/m3, which means that the air germ count in the pulmonary clinic room meets the requirements and there is also no bacterial growth of Mycobacterium tuberculosis. The results of the risk characteristics in theMicrobial Risk Assessmentin this study are the risk level (HQ) in the hospital's pulmonary clinic staff of less than one which indicates that the risk agent does not cause adverse health effects on pulmonary clinic staff and there is also no growth of Mycobacterium tuberculosisbacteria. Suggestions that can be given to the hospital are disinfection, installation of exhaust fans in the hospital pulmonary clinic room to regulate air circulation.
