European Centre for Disease Prevention and Control. Healthcare-associated infections: surgical site infections. In: ECDC. Annual epidemiological report for 2017. Stockholm: ECDC; 2019.

This report is based on data for 2017 retrieved on 18 July 2019 from The European Surveillance System (TESSy) and ECDC’s decentralised data storage for antimicrobial resistance and healthcare-associated infections (ARHAI). TESSy is a system for the collection, analysis and dissemination of data on communicable diseases. EU/EEA countries contribute to the system by uploading their infectious disease surveillance data at regular intervals. The ARHAI decentralised data storage is a system allowing EU/EEA countries to store their surveillance data on their national servers in TESSy data format.

Executive Summary

Key facts:

  • Surgical site infections (SSIs) are among the most common healthcare-associated infections (HAIs). They are associated with longer post-operative hospital stays, additional surgical procedures, treatment in intensive care units and higher mortality.
  • In 2017, 12 EU Member States and one EEA country reported SSIs for nine types of surgical procedure to ECDC.
  • During this period, 10 149 SSIs were reported from a total of 648 512 surgical procedures.  
  • The percentage of SSIs varied from 0.5% to 10.1%, depending on the type of surgical procedure.
  • The incidence density of in-hospital SSIs per 1 000 post-operative patient-days varied from 0.1 to 5.7, depending on the type of surgical procedure.
  • From 2014 to 2017, a statistically significant increasing trend was observed for both the percentage of SSIs and the incidence density of in-hospital SSIs following laparoscopic cholecystectomy (CHOL).
