“…Despite the Australian Vascular Audit being compulsory, evidence suggests that it only contains 63% of procedures, and therefore outcomes may be prone to selection bias. 8,33 Furthermore, the retrospective nature of the analysis performed in this study cannot account for all the potential differences in patient selection between countries and this makes comparisons difficult. Some confounders within the analysis have been adjusted for, but this adjustment was bound by the available data and adjustment for co-morbidity was limited to diabetes, cardiac disease, and renal impairment.…”

“…Case ascertainment rates have been reported previously at > 90% of aortic procedures performed in Denmark, Hungary, Malta, New Zealand, Sweden, and the UK, 80% in Norway and 63% in Australia. 2,8 The Finnish registry collects complete data from the Helsinki region, but not the whole of Finland. The Vascular Quality Initiative (VQI) collects data from over 700 units in North America capturing about 23% of AAA repairs in the United States and the German Registry has over 130 participating centres.…”

“…There was an inverse correlation between both surgeon volume of open aortic aneurysm repair, hospital volume of thoracic EVAR and in hospital mortality. These findings suggest that in Australia TEVAR should be performed by high volume hospitals and OSR by high volume surgeons [220]. Esce et al analysed 11,086 intact AAA repair s between 2000 and 2008 using the New York Statewide Planning and Research Cooperative System inpatient database and determined 6 cases per year as the threshold to achieve the improved mortality of a high volume center [221].…”

“…This registry based study from Australia investigated the impact of hospital and surgeon volume on the outcome of abdominal aortic aneurysm repair over a seven year period. 1 In keeping with contemporary data the authors were unable to identify any volume effect for endovascular aneurysm repair (EVAR), 2 and somewhat more surprisingly no volume effect for open repair at surgeon or hospital level. The EVAR group included both complex EVAR cases and thoracic endovascular aneurysm repairs (TEVARs), both of which had expected higher mortalities, of 2.6% and 5.6%, respectively.…”
