Editor’s Choice – Recommendations for Registry Data Collection for Revascularisations of Acute Limb Ischaemia: A Delphi Consensus from the International Consortium of Vascular Registries


To develop a minimum core data set for evaluation of acute limb ischaemia (ALI) revascularisation treatment and outcomes that would enable collaboration among international registries.


A modified Delphi approach was used to achieve consensus among international multidisciplinary vascular specialists and registry members of the International Consortium of Vascular Registries (ICVR). Variables identified in the literature or suggested by the expert panel, and variables, including definitions, currently used in 15 countries in the ICVR, were assessed to define both a minimum core and an optimum data set to register ALI treatment. Clinical relevance and practicability were both assessed, and consensus was defined as ≥ 80% agreement among participants.


Of 40 invited experts, 37 completed a preliminary survey and 31 completed the two subsequent Delphi rounds via internet exchange and face to face discussions. In total, 117 different items were generated from the various registry data forms, an extensive review of the literature, and additional suggestions from the experts, for potential inclusion in the data set. Ultimately, 35 items were recommended for inclusion in the minimum core data set, including 23 core items important for all registries, and an additional 12 more specific items for registries capable of capturing more detail. These 35 items supplement previous data elements recommended for registering chronic peripheral arterial occlusive disease treatment.


A modified Delphi study allowed 37 international vascular registry experts to achieve a consensus recommendation for a minimum core and an optimum data set for registries covering patients who undergo ALI revascularisation. Continued global harmonisation of registry infrastructure and definition of items allows international comparisons and global quality improvement. Furthermore, it can help to define and monitor standards of care and enable international research collaboration.



International Consortium of Vascular Registries

The International Consortium of Vascular Registries (ICVR) has rapidly developed into a global collaborative. Given the importance of vascular devices for public health, this is a priority direction for regulators, manufacturers, payers and patients advocacy groups. It is an innovative effort building on successes achieved in orthopedics and promotes cohesion among international registries. The ICVR will enable a collaboration of stakeholders to create a sustainable global system to evaluate the safety and efficacy of new and existing vascular devices and procedures, while promoting innovation and quality improvement.

The Impact of Centralisation and Endovascular Aneurysm Repair on Treatment of Ruptured Abdominal Aortic Aneurysms Based on International Registries


Current management of ruptured abdominal aortic aneurysms (RAAA) varies among centres and countries, particularly in the degree of implementation of endovascular aneurysm repair (EVAR) and levels of vascular surgery centralisation. This study assesses these variations and the impact they have on outcomes.

Materials and methods

RAAA repairs from vascular surgical registries in 11 countries, 2010–2013, were investigated. Data were analysed overall, per country, per treatment modality (EVAR or open aortic repair [OAR]), centre volume (quintiles I V), and whether centres were predominantly EVAR (≥50% of RAAA performed with EVAR [EVAR(p)]) or predominantly OAR [OAR(p)]. Primary outcome was peri-operative mortality. Data are presented as either mean values or percentages with 95% CI within parentheses, and compared with chi-square tests, as well as with adjusted OR.


There were 9273 patients included. Mean age was 74.7 (74.5–74.9) years, and 82.7% of patients were men (81.9–83.6). Mean AAA diameter at rupture was 7.6 cm (7.5–7.6). Of these aneurysms, 10.7% (10.0–11.4) were less than 5.5 cm. EVAR was performed in 23.1% (22.3–24.0). There were 6817 procedures performed in OAR(p) centres and 1217 performed in EVAR(p) centres. Overall peri-operative mortality was 28.8% (27.9–29.8). Peri-operative mortality for OAR was 32.1% (31.0–33.2) and for EVAR 17.9% (16.3–19.6), p < .001, and the adjusted OR was 0.38 (0.31–0.47), p < .001. The peri-operative mortality was 23.0% in EVAR(p) centres (20.6–25.4), 29.7% in OAR(p) centres (28.6–30.8), p < .001; adjusted OR = 0.60 (0.46–0.78), p < .001. Peri-operative mortality was lower in the highest volume centres (QI > 22 repairs per year), 23.3% (21.2–25.4) than in QII-V, 30.0% (28.9–31.1), p < .001. Peri-operative mortality after OAR was lower in high volume centres compared with the other centres, 25.3% (23.0–27.6) and 34.0% (32.7–35.4), respectively, p < .001. There was no significant difference in peri-operative mortality after EVAR between centres based on volume.


Peri-operative mortality is lower in centres with a primary EVAR approach or with high case volume. Most repairs, however, are still performed in low volume centres and in centres with a primary OAR strategy. Reorganisation of acute vascular surgical services may improve outcomes of RAAA repair.
