The aim of this study was to evaluate a new joint arthroplasty clinical priority scoring tool.

A new arthroplasty scoring tool based on pain, function, social limitation, potential of benefit from surgery and consequence of more than 6 months delay was developed and evaluated using 16 patient scenarios (vignettes) related to hip and knee osteoarthritis. Sixteen orthopaedic surgeons were asked to score the vignettes using clinical ranking, ISS tool and the new tool.

Significant variation in ranks allocated by surgeons was recorded for all three tools. Vignettes at either end of the scale ie. those who are severely or minimally disabled had less variability compared to a large group in the middle range. Comparing the three tools there did not appear to by any advantage of one over the other. Most of the variations occurred in the interpretation of benefit from the operation and consequence of delay.

Scoring tools rely heavily on judgement based decisions. More work is required to understand judgement processes used by surgeons and audit/feedback mechanisms may help in reducing the variations in priority assignment.
