3 Fig 2 Clinic visit data before and after modifying the imaging protocol. A, The proportion of patients requiring additional imaging before and after imaging protocol redesign. B, The total number of preoperative clinic visits per patient before and after imaging protocol redesign.

4 Fig 3 Instrument usage data before and after modifying the instrument trays. A, The number of instruments opened per case before and after process redesign. B, Instrument cost per case before and after process redesign. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2015 Society for Vascular Surgery Terms and Conditions

5 Fig 4 Endovascular aneurysm repair (EVAR) technical margin outcomes. The graph depicts the 10% reduction in mean EVAR-associated technical costs before and after process redesign. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2015 Society for Vascular Surgery Terms and Conditions

6 Fig 5 Shifts in vendor market share during the course of the study due to the surgeon's increased awareness of stent graft cost and factoring of device cost into case planning. Each letter represents a different vendor. Over time, vendor A, the most expensive of the stent grafts, derived a smaller segment of the market share.
