title: What is a reasonable orthopaedic surgical workload? An analysis of elective and trauma workloads using two different complexity scoring systems.
abstract: A 1-year prospective study of all surgical activity was undertaken by the Orthopaedic Unit using two weighting systems for operative complexity: the Intermediate Equivalent (IE) and the Operative Complexity Score (OCS). The objectives were to define the difference between caseload and workload, and to formulate a reasonable workload for an operating session and a reasonable annual workload for a consultant team. In both elective and trauma surgery the BUPA complex, major+ and major operations represented 50 per cent of the caseload but accounted for approximately 68 per cent of the workload. The BUPA minor and intermediate procedures representing the remaining 50 per cent of the caseload accounted for only 32 per cent of the workload. The number of hours required to undertake all the complex, major+ and major operations was approximately twice that required for the number of minor and intermediate procedures. Despite the marked variation in case mix, the workload achieved by the six teams in the same number of sessions was remarkably similar. On the basis of two consultant and one registrar elective lists per week, a total of 705 IEs (1795 OCS units) could be undertaken by each team in 1 year. An average of 458 IEs (1086 OCS units) of trauma surgery were undertaken by each team. Caseload is a poor performance indicator of surgical activity. This study supports the concept of 3.5-4.0 IEs as reasonable workload for an orthopaedic elective operating session, and 900 IEs (2200 OCS units) as a reasonable annual workload for an orthopaedic team.
