Valutazione e quantificazione del rischio biologico in ambito ospedaliero mediante determinazione dell'ATP sulle superfici di lavoro.

The purpose of this study was to establish whether a method of determining ATP levels using the HY-Lite system could be reliably applied in the various hospital workplaces. We estimated the correlation between ATP levels and the number of C.F.U. (Colony Forming Units), observed correlation r = 0.96. We established hygienically acceptable values for each environment, and drew up reference tables. The study reveals that conditions of high bacterial and fungine contamination can occur, albeit the agents are not normally pathogenic is so far as they consist of common environmental pollutants. Consequently, these results emphasize the need to apply strict sanitization and hygienic measures, that health workers must be suitably trained to deal with follow. The results of the sampling appear to suggest that condition of potential biological risk for workers are largely due to incorrect work procedure in workplaces where pathologic agents are present.
