Microbiological environmental monitoring in high-risk departments during building activities in a hospital site.

BACKGROUND This study examines the microbial and fungal contamination associated with the presence of renovation works in a hospital site in Sardinia (Italy). METHODS Microbiological environmental monitoring was carried out before, during and at the conclusion of the works in the Ophthalmology Department in view of a risk assessment procedure. RESULTS Although the median values of microbial and fungal counts were found raised during the works, protective measures set out by the internal procedures limited the contamination level. CONCLUSIONS This study emphasizes the benefits of environmental surveillance for airborne contamination to help prevent outbreaks of nosocomial mycosis associated with construction work.
