• The percentage of SSIs varied from 0.6% in laminectomies to 9.6% in open colon surgery, dependingon the type of surgical procedure.
• The incidence density of in-hospital SSIs per 1 000 post-operative patient-days varied from 0.1 to 5.3,depending on the type of surgical procedure.
• Comparing 2022 to 2021, two additional countries reported data to ECDC. France continued theirreporting after a pause, and Belgium reported SSI surveillance data for the first time.
