Abstract
Objectives: The objective of this study was to determine the outcomes of carotid endarterectomy (CEA) in New South Wales, Australia. Methods: This state-wide prospective audit of all public and private hospitals during a 6-month period had main outcome measures of 30-day mortality, 30-day fatal stroke, 30-day nonfatal stroke, and 30-day combined stroke and mortality. Results: Fifty-three of 54 eligible surgeons participated (response rate, 98%). The audit obtained inpatient data for 689 internal CEA procedures performed on 666 patients. Of 666 first or only procedures, 462 (69.4%) were performed on patients who were symptomatic and 204 (30.6%) on patients who were asymptomatic. After adjustment for cluster by surgeon, we determined a state-wide 30-day death rate of 1.2% (95% CI, 0.3% to 2.1%), a 30-day fatal or nonfatal stroke rate of 3.0% (95% CI, 1.6% to 4.4%; ipsilateral stroke, 2.6%), a 30-day nonfatal stroke rate of 2.3% (95% CI, 1.1% to 3.4%; ipsilateral stroke, 2.0%), and a 30-day combined stroke and death rate of 3.5% (95% CI, 2.1% to 4.9%). A significant linear relationship was found between patient preoperative hypertensive status and the combined 30-day stroke and death rate (trend odds ratio, 3.5; 95% CI, 1.6 to 7.7). No association was seen between any main outcome measures and hospital volume (<10 CEAs versus ≥10 CEAs). Four patients underwent surgery outside guideline recommendations (CEA performed for either ≤30% stenosis or occluded carotid artery). Conclusion: This first comprehensive state-wide audit confirms that Australian surgeons achieve 30-day outcomes comparable with international benchmarks. (J Vasc Surg 2002;36:62-9.)
