In a healthcare facility with two hospitals (A and B), 6 non-latex asthma cases were diagnosed between 1998 and 2000 on hospital A's top floor, which had water incursions during this period. Hospital A had more work-related lower respiratory symptoms, with higher levels on the top floors. Univariate models showed positive associations between lower respiratory symptoms and a number of air, and chair and floor dust analytes including; endotoxin, ultrafine particles, culturable fungi, spore counts, EPS-Pen/Asp, fungal glucans, latex allergen, and cat allergen. In multiple regression models work-related asthma symptoms were associated with subjective assessment for signs of water incursion, ultrafme particles in air, culturable Penicillium/Aspergillus in chair dust, and EPS-Pen/Asp in floor dust. This study contributes to the growing knowledge base in the field of indoor environmental research by showing that there were relationships between work-related asthma symptoms and our indices of exposure to biologicals and particles.
