During the first phase of the study, 4,238 patients will be recruited and the baseline incidence of surgical site infection at each participating site will be determined. At the beginning of the third year, the bundle will be implemented and data on 4,238 additional patients will be collected. The incidence rate on surgical site infection before and after the intervention will be compared. We hypothesize that this intervention will reduce the infection rate within the first 3 months after surgery from 6% to 4.5% (5% to 3.75% in closed fractures and from 10% to 7.5% in open fractures).
