An assessment of the POSSUM system in orthopaedic surgery

J Bone Joint Surg Br. 2002 Jul;84(5):735-9. doi: 10.1302/0301-620x.84b5.12626.


We describe the development and validation of a scoring system for auditing orthopaedic surgery. It is a minor modification of the POSSUM scoring system widely used in general surgery. The orthopaedic POSSUM system which we have developed gives predictions for mortality and morbidity which correlate well with the observed rates in a sample of 2326 orthopaedic operations over a period of 12 months.
