Abstract

OBJECTIVES: Operative caseload is thought to be associated with peri-operative mortality following intact aortic aneurysm repair. The aim was to study that association in the Australian setting, which has a unique healthcare provision system and geographical population distribution. METHODS: The Australasian Vascular Audit database was used to capture volume measurements for both individual surgeon and hospital and to separate it into quintiles (1, lowest, to 5, highest) for endovascular (EVAR), open surgical repair (OSR), and subgroups of repair types between 2010 and 2016. Multivariable logistic regression modelling was used to assess the impact of caseload volumes on in hospital mortality..
