The classification’s basic principle is to grade complications according to the treatment that is induced to treat the complication. It consists of 5 grades with 2 grades being further subdivided.
Hence, the classification enables its use in a contracted or extended form depending on the user’s objective. The classification eliminates subjective interpretation of serious adverse events and any tendency to down-rate complications, because it is based on data that is usually well documented and easy to verify. It is also well suited for retrospective analyses.
In order to further avoid subjectivity in complication reporting, we purposely avoided qualitative terms such as ‘minor’ or ‘major’ to grade the complications.
Any deviation from the ideal postoperative course that is not inherent in the procedure and does not comprise a failure to cure.
Diseases or conditions that remain unchanged after surgery.
Are conditions that are inherent in the procedure, and that thus will inevitably occur (such as scar formation or the inability to walk after an amputation).
