To assess the impact of a quality assured planning and sizing process and the endovascular team briefing (preprocedure run through and brief - PRTB) on the delivery of endovascular aneurysm repair (EVAR), in Edinburgh.Design:
Prospective observational study, comparing parameters before and after the intervention.Materials:
Prospectively collected database recording infrarenal aneurysms treated with EVAR performed from January 2007 to April 2014 at our institution. The total screening time, iodinated contrast volume used, radiation dose, endovascular training opportunities, and hospital length of stay were recorded.Methods:
A comparison before (January 2007 to November 2011) and after (December 2011 to April 2014) the introduction of the PRTB was made for each of these variables. Multiple linear regression analysis was performed to account for the learning effect.Results:
In this study, 61 EVAR cases were performed prior to and 44 EVAR cases after the introduction of the PRTB. Univariate Mann-Whitney tests suggested a significant difference between before PRTB introduction and after PRTB introduction on all outcome variables except procedure time. Multiple linear regression analysis results showed a statistically significant improvement in outcomes after the change point for all outcomes except for radiation dose. Endovascular training opportunities were realized in 12/61 (20%) before compared to 42/44 cases (95%) after PRTB introduction.Conclusions:
By introducing rigorous quality assurance and utilizing the principles of crew resource management to the EVAR process, it is possible to reduce screening times, contrast use, hospital length of stay, and improve endovascular training opportunities.
