Palmer, Eboni D., Health Risk Associated with Microbial Contamination in Healthcare Facilities. Master of Public Health (Occupational Health Practice), July 2007, 96 pp., 20 tables, 8 illustrations, bibliography, 140 titles. This study developed a model assessing the risk associated with indoor microbial contamination in health care facilities. A semi-quantitative model resulting in numerical scores was used to describe the severity of risk associated with given levels of contamination. The hospital used in this study had problems with water intrusion. There were 99 locations from 3 air handler unit (AHU) service area locations examined. The final results produced a health risk rating for all three AHUs of medium risk. There is an increased risk of adverse health outcomes due to exposure from environmental microbial contamination. Immunocompromised patients and patients with allergies are not protected from the risk of developing a nosocomial infection or allergic reaction. Remediation of the contaminated areas must be performed in order to reduce the risk.
