BACKGROUND: Recent research evidence has impacted the practice of carotid endarterectomy (CEA). We aim to characterize changes in the practice and outcome of CEA over time in a single large-volume stroke centre. METHODS: All patients who underwent CEA from 2004 to 2014 and carotid angioplasty and stenting (CAS) from 2003 to 2008 at an Australian metropolitan tertiary stroke centre hospital were included. Clinical data were analysed to identify time trends in choice of intervention, patient selection, preoperative imaging utilization, surgical timing and outcome. RESULTS: There were 510 CEAs performed during 2004-2014 and 95 CASs during 2003-2008. The proportion of patients undergoing CEA compared to CAS increased from 60% to 90% from 2004 to 2008 (P < 0.001). CAS patients were more likely to have cardiac co-morbidities. From 2004 to 2014, the proportion of CEA patients aged ≥80 years increased (P = 0.001) and the proportion of asymptomatic patients decreased (P = 0.003) over time. Median time from symptom onset to surgery decreased from 52 days (Q1: 25, Q3: 74) in 2004 to 8 days (Q1: 5, Q3: 37) in 2014 (P < 0.001). Use of preoperative ultrasonography decreased whilst CT angiography and the number of imaging modalities applied to each patient increased over time (P < 0.001). Overall, 5.9% of CEAs were complicated by death, stroke or acute myocardial infarction with no significant change over time. CONCLUSION: The trends in CEA practice at our centre align with international trends and guidelines. This study provides a representative indicator of Australian hospital practice, and illustrates how evidence from research is translated into clinical care.
