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.
