Surgical site infections (SSIs) are the most complication after a surgical operation and their incidence reaches 20% worldwide. SSIs have been associated to significant morbidity and mortality, high ICU admission rates, increased length of hospital stay, high readmission rates and raised cost. However, there is no registry for SSIs in Greece so far. In addition, it has been considered that almost half of SSIs could be prevented. Therefore, several prevention strategies have been suggested by international health organizations, such as WHO and NICE, that seem to be effective. The aim of the present study is to investigate the effect of 10 prevention bundles on the rate of SSIs, as well their consequences on several financial parameters of the Greek healthcare system.
