A prospective clinical audit was carried out to assess the volume and distribution of workload generated by vascular surgical emergencies over a 3-month period in a single health district in the UK. Of 53 consecutive patients referred as surgical emergencies with peripheral vascular problems, 45 were referred to a single vascular surgeon, 36 directly from a general practitioner or other specialist and nine from another general surgeon. A total of 39 operations and six radiological procedures were carried out, including 26 vascular reconstructions. To accommodate the 27 non-urgent operations, nine were performed 'out of hours' and 17 planned cases were cancelled. A median of five general surgical beds were required throughout the period studied and 11 patients required intensive therapy unit admission for a total of 39 days. It is concluded that vascular surgical emergencies constitute a substantial workload and are being dealt with mainly by a single vascular surgeon who effectively works a one in one rota. Inadequate facilities for urgent vascular surgery lead to a large number of cases being dealt with out of hours and frequent cancellation of routine operations.
