Health Risk Assessment and Monte Carlo Simulation of Microorganism Aerosol Pollution at the Intensive Care Unit of Dr. Wahidin Sudirohusodo Hospital. Makassar

Microorganism pollutants can be bacteria, fungi and spores in the room. Microorganisms that are distributed in space are known as bioaerosols. The spread of bioaerosol in hospitals can result in danger to human health, especially for patients with weakened immune systems. Risk assessment is very important for an organization or institution to overcome current and future risks related to contamination. The QMRA approach has been applied to inform standards for the microbiological quality of food, water, air, and touched surfaces. The method uses descriptive analytics with a literature review design. Data was obtained through searches on the electronic databases Pubmed , Elsevier , and Google Scholar. Keyword terms such as: (Bioaerosol * and Airborne * and Infections * and Hospital *) , ( Bioaerosol * and Microorganisms * and Inhalation ) , ( Airborne * and Microbial and * Hospital * or Intensive Room *) , ( Bioaerosol * Quantitative Microbial Risk Assessment (QMRA)* and Hospital-Acquired Infection* and Intensive Care unit ) . health risks AND sensitivity AND aerosol pollution AND microorganisms OR fungi OR bacteria AND montercarlo AND intensive care OR hospital rooms: (Bioaerosol * and Airborne * and Infections * and Hospital *) , ( Bioaerosol * and Microorganisms * and Inhalation ) , ( Airborne * and Microbial and * Hospital * or Intensive Room *) , (Bioaerosol * Quantitative Microbial Risk Assessment (QMRA) * and Hospital-Acquired Infection * and Intensive Care unit ) . health risks AND sensitivity AND aerosol pollution AND microorganisms OR fungi OR bacteria AND monter carlo AND intensive care OR hospital rooms are used. The search covered research conducted over the past ten years, from 2012 to 2022. Of the 27 articles found using the search terms, seventeen articles were selected for examination. The four categories of analysis are population, type of study, aims, and findings. According to research, one of the parameters for evaluating indoor environmental quality is bioaerosol. Microbial bioaerosol media in the air are ambient air and indoor air. The routes of exposure can be through ingestion/swallowing, direct contact and inhalation/inhalation. The cause of hospital infections is because hospital environmental conditions do not meet the requirements, causing high levels of room air germs. Poor hospital indoor air quality can cause HAIs. Therefore increasing levels of mechanical or natural ventilation as well as regular cleaning and maintenance activities can play an important role in improving indoor air quality.
