Caseload or workload? Scoring complexity of operative procedures as a means of analysing workload

To present a more realistic assessment of surgical workload than that provided by a case count.

Prospective study of all the operative procedures performed in one year, classified according to the British United Provident Association's schedule of procedures and scored by the "intermediate equivalent" value (taking the recommended fee value of an intermediate operation as 1.0) compared with the number of operations performed.

General surgical unit of Taunton and Somerset Hospital, comparing four consultant surgeons and their teams.

Inpatients and day patients admitted under the care of general surgeons during 1989.

Difference between the apparent workload represented by simple case counting (caseload) and the actual workload represented by calculation of the total "intermediate equivalent" value.

The workload assessed in terms of intermediate equivalent values was greater than that suggested by case counting for complex operations (12% v 4%), operations at the district hospital (82% v 74%), and operations performed by consultants (53% v 35%) and was lower for minor operations (20% v 42%), operations at the community hospitals (18% v 26%), and operations performed by surgeons in training grades and clinical assistants (47% v 66%).

The use of the intermediate equivalent values as an indicator of complexity allows a more realistic assessment of the operative workload than a simple case count of the number of different operations and is recommended for comparing workload in different hospitals and departments.
