Background: Although carotid endarterectomy is increasing in the UK, there
is evidence that the procedure is still underused. Methods of reducing cost
in a single vascular unit have been assessed using a continuous audit incl
uding outcome measures.
Methods: A consecutive series of 333 patients admitted over 7 years under a
single consultant surgeon were studied. Outcome measures included the rate
of perioperative neurological complication of any kind, and death. The len
gth of hospital stay and the number of readmissions within 30 days were rec
orded prospectively by computerized audit.
Results: Over the interval of the study, the number of preoperative investi
gations was reduced; angiography and cerebral computed tomography were rese
rved for specific indications. The median duration of hospital stay decreas
ed from 7 to 2 days. There was no change in the stroke and death rate (3 pe
r cent) during the study and only two patients required readmission within
30 days.
Conclusion: Carotid endarterectomy can be performed cost-effectively using
non-invasive preoperative investigations for the majority of patients. In-h
ospital stay has been reduced and the routine use of intensive care replace
d by a 2-h stay in theatre recovery. These changes have been achieved witho
ut compromising patient safety.
