Various interpretations of the indications for carotid endarterectomy exist. Physician knowledge as it relates to the decision to proceed or recommend carotid endarterectomy was investigated, using disaggregate discrete choice analysis. Canadian neurologists, neurosurgeons, vascular surgeons, and internists were surveyed. The degree of stenosis was most important, followed by symptoms, comorbid illness, and arterial imaging modality. No differences existed by specialty. Canadian physicians in four specialties are knowledgeable about results of randomized clinical trials for carotid endarterectomy. |
