GRASP Special Seminar: Lee White, University of Washington, “Quantitative Objective Assessment of Preoperative Warm-up for Robotic Surgery”

July 25, 2013 @ 4:00 pm - 6:00 pm

Abstract: Here I present the application of three established methods for
quantitatively and objectively assessing robotic surgical performance as
well the development and application of a fourth. These four tools are
used to assess the hypothesis that a certain surgical warm-up protocol
improves performance of surgeons on a da Vinci robotic surgical system.
In the protocol, surgeons perform a brief warm-up task on the Mimic
dV-Trainer virtual reality simulator prior to performing one of two
robotic surgery practice tasks.

Of the four techniques used for performance assessment, the three
established techniques consist of basic measures (task time, tool path
length, economy of motion and errors), algorithmic assessment (using
trained Hidden Markov Model machine learning algorithms) and surgeon
assessment (using the Global Evaluative Assessment of Robotics Surgery).
The newly proposed technique called Crowd-Sourced Assessment of
Technical Skill (C-SATS) draws on crowds of people on the Internet to
assess the surgical performance. The evidence that warm-up improves
surgical performance is presented as well as an analysis of the strong
agreement between C-SATS and grades provided by a group of surgeons
trained to assess surgical performance.

Lee Woodruff White is the first and only son of Jane Woodruff Grant and
Paul Howard White. They raised him and his sister Mariah in Eugene,
Oregon where he earned an International Baccalaureate Diploma at the
Eugene International High School and graduated from South Eugene High
School in 2004. In 2008, Lee graduated Magna Cum Laude from the Tulane
University of Louisiana with a Bachelor of Science in Engineering,
earning Departmental Honors from the Biomedical Engineering Department.
He joined the BioRobotics Laboratory where he was advised by Professor
Blake Hannaford and Surgeon Thomas S. Lendvay. In 2013 he earned the
Doctor of Philosophy degree in Bioengineering from the University of
Washington. He will continue his education at Stanford University
School of Medicine and hopes to pursue a career bridging engineering and
