Surgical site infection surveillance

Surgical site infection (SSI) is the third most commonly reported nosocomial infection and accounts for 14–16% of all nosocomial infections among hospital inpatients. A successful SSI surveillance programme includes standardized definitions of infection, effective surveillance methods and stratification of the SSI rates according to risk factors associated with the development of SSI. Surveillance with feedback of information to surgeons and other relevant staff has been shown to be an important element in the overall strategy to reduce the numbers of SSIs. This paper examines the essential components of a SSI surveillance system including surveillance methods, data collection and handling, analysis and presentation of results to clinical staff.
