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

Abstract

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.
