Project summary

Background

Around 100,000 elective hip and knee replacement procedures are performed in England’s NHS each year.  A small but important proportion need to be revised, and joint revision is the standard indicator of the quality of surgery in these low-mortality operations. We followed our work in other specialities on unplanned reoperation (return to theatre) by defining this measure for orthopaedics as it is considered more sensitive to the surgeon’s performance than is revision. By augmenting administrative data with our own surveys, we have also investigated the relation between patient outcomes and both VTE prophylaxis and laminar flow theatres.

Aims

• To explore the utility of return to theatre as a marker of quality of surgical care
• To evaluate policies aimed at reducing complications
