Abstract
Introduction
The objective was to present the results of the Slovenian National surgical site infections (SSIs) surveillance system from 2013 to 2016 and to compare them to the reference data for the European Union (EU) and European Economic Area (EEA) countries.
Methods
Surveillance was conducted according to the Slovenian protocol consistent with the European Centre for Disease Prevention and Control protocol. Descriptive analyses were performed.
Results
Data were collected for 1080 patients of whom 57.4% were patients with cholecystectomy (from three hospitals), 29.0% with caesarean sections (from four hospitals) and 4.7%, 4.5% and 4.4% patients with hip prosthesis, knee prosthesis and colon surgery (each surgical category from one hospital). The pooled in-hospital SSI incidence density for caesarean section was 3.7 (95% CI: 1.4-8.1; inter-hospital range: 0.0–11.5) and for cholecystectomy 6.8 (95% CI: 3.5-11.9; inter-hospital range: 4.1–11.9) per 1000 post-operative patient-days. The in-hospital SSI incidence density for colon surgery was 24.8 (95% CI: 12.5-44.0) and for hip prosthesis 2.6 (95% CI: 0.1-14.2) per 1000 post-operative patient-days. No SSIs were reported among the 49 patients with knee prostheses.
Conclusions
The estimated SSIs incidence rates varied between different surgical categories and the different participating hospitals. In some of the participating hospitals and for some of the surgical procedures under surveillance they were rather high in comparison to the reference data for hospitals from EU/EEA countries. It is urgent to expand standardised SSIs surveillance to all Slovenian acute care hospitals with surgical wards to contribute to evidence-based SSIs prevention and control in Slovenia.
