Background: In New Zealand (NZ), there are two major sources of operative data for abdominal aortic aneurysm (AAA) repair: the Australasian Vascular Audit (AVA) and the National Minimum Data Set (NMDS). Since the introduction of the AVA in NZ, there has not been any attempt at the validation of outcome data. The aims of this study were to report the outcomes of AAA repair and validate the AAA data captured by AVA using the NMDS. Methods: AAA procedures performed in NZ from January 2010 to December 2014 were extracted from the AVA and NMDS. Patients identified from the AVA had their survival status matched to the NMDS. Only primary AAA procedures were included for the analysis, with re-interventions and graft infections excluded. Demographical, risk factors and outcome data were used for validation. Results: The number of patients undergoing primary AAA procedure from AVA and NMDS was 1713 and 2078, respectively. The AVA inpatient mortality for elective and rupture AAA was 1.6 and 32.2%, respectively. The NMDS 30-day mortality from AAA was 2.5 and 31.5%. Overall, 1604 patients were available for matching, and the NMDS correctly reported 98.1% of endovascular aneurysm repair and 94.2% of elective AAA repairs; however, there were major differences in comorbidity reporting between the data sets. Conclusion: Both data sets were incomplete, but combining administrative (NMDS) and clinical (AVA) data sets provided a more accurate assessment of mortality figures. More than 80% of AAA repairs are captured by AVA, but further work to improve compliance and comorbidity documentation is required.
