The DANOP-DATA system: a low-cost personal computer based program for monitoring of wound infections in surgical ward.

A low-cost personal computer program to monitor surgical wound infections was developed in parallel to the Danish national guidelines for recording postoperative wound infections. Internationally accepted definitions were used. The program offers three fixed-data entry screens and produces user-specified variations of four standard tables, comprising most of the epidemiological data needed for surveillance and infection control. The program was tested in Danish hospitals and was found to serve well as a simple local tool for the operating staff, offering fast information on infection rates. Results from two hospitals consisting of 3904 operations are presented. Infections occurring after discharge were included. Overall infection rates for clean wounds were 2.3%, clean-contaminated wounds 4.7%, contaminated wounds 4.3% and dirty operations 8.3%. None of the hospitals had used infection surveillance systems before.
