Meta-analysis on surgical infections may be a useful tool that can provide more accurate outcome estimates than other conventional types of studies. Published meta-analyses in surgical infections tend to focus mainly on the use of antimicrobial prophylaxis and on the comparison of different procedures or techniques for the treatment of surgical infections. The majority concern surgical infections in abdominal surgery. However, mortality is reported as primary outcome in few meta-analyses. Meta-analyses focusing exclusively on surgical infections, reporting data on mortality as a primary outcome, and comparing different antibiotic regimens for the treatment of surgical infections should be conducted.
