Vascular Surgery Research


Vascular Surgery concentrates its research efforts in clinical and outcomes research.

Vascular Surgery participates in the Vascular Quality Initiative, a national registry of vascular surgical outcome data used for both quality and with appropriate protection of patient specific data, research on vascular surgical outcomes. 

The Vascular Surgery Faculty also participates in the Surgical Outcomes and Applied Research initiative, SOAR, a collaboration between the Department of Surgery and the Colorado Health Outcomes Program.  Dr. David Kuwayama and Dr. Mark Nehler are principal participants in the program. Please visit the SOAR web pages for more information.
