This study states that Lower mortality after open abdominal aortic aneurysm repair (OAAAR) has been demonstrated in the Society for Vascular Surgery Vascular Quality Initiative (VQI) database compared with previously published reports of other national registries. Understanding these differences is essential as these data sets increasingly inform clinical guidelines and health policy.
The χ2 tests were used for frequencies, analysis of variance for continuous variables. A multivariate analysis using logistic models for in-hospital and 30-day mortality adjusting for age, sex, race, comorbidities, and smoking status was also performed.
In total, data from 8775 patients were analyzed. Significant differences were seen across baseline characteristics. In addition, the availability of patient and procedural data varied widely across data sets. There are fundamental important differences in patient demographics, comorbidity profiles, and outcomes after OAAAR across widely used national registries. This may represent differences in outcomes between institutions that elect to participate in the VQI or NSQIP vs the broader results obtained from the NIS. In addition to avoiding direct comparison of information derived from these databases, it is critical that these differences be taken into account in making policy decisions and guidelines based on these data repositories.
