Healthcare-Associated Infection Surveillance in Europe
Many European countries created national systems for the surveillance of Healthcare-associated infections (HAI), due to the different definitions and methodology of data collection comparison between the countries was impossible before. The HELICS project (Hospitals in Europe Link for Infection Control through Surveillance) was the first step towards the standardization of HAI data [ 1 , 2 ]. HELICS was a Europe-wide HAI surveillance program launched in 1994, mainly focusing on surgical site infections [3] .
