Study stepsWeill CornellDartmouth-HitchcockDukeOneFloridaVQI
Case Identification StrategyEMR Search: CPT 0245T (endovascular repair of iliac artery bifurcation)Record of institutional IBE device implantations obtained from local Gore representativeDuplicate queries of EMR and surgical finance records using Gore IBE device catalogue numbers as search termsSearch 1: Query of Unique Device Identification System using Gore IBE and VBX stent graft device catalogue numbers
Search 2: Qualitative query of OR supply usage and case data fields with search criteria: ‘Gore’ and ‘endovascular’ or ‘endoprosthesis’ and ‘VBX’ or ‘ILIAC’
VQI Search: ‘Device’=gore, and ‘iliac distal endpoint’=external and internal (branched)
Case ConfirmationChart review confirmation of IBE+VBX stent graftChart review confirmation of IBE+VBX stent graftChart review confirmation of IBE+VBX stent graftChart review confirmation of IBE+VBX stent graftIBE and VBX stent graft devices implanted on the same laterality; VBX stent graft implanted in internal iliac artery
