“…Expertise is developed and maintained at any task through extensive time spent in ‘deliberate practice' of the skill [25] and is developed through critical analysis of experience and adaptation of behavior to achieve a desired outcome. Procedural competency is difficult to define in general and can be based on expert consensus, objective measures, or self-reporting [26]. Further work to establish competency assessment in TORS procedures is needed.…”

Purpose: To define a curriculum for the development of robotic surgical skills in otorhinolaryngology residency training. Methods: A systematic review of the current literature on robotic surgery training was performed. Based on prior reports in other specialties, a curriculum for otorhinolaryngology residents was created that progresses through several modules, including didactics, inanimate skills laboratory, and operative experience. Results: The curriculum for residents in otorhinolaryngology was designed as follows: didactics include an overview of the robotic device and instruments, a tutorial in basic controls and function, and a room setup and positioning. The anatomy and steps of transoral procedures are taught through books, videos, operative observations, and cadaver dissections. Skills are developed with a virtual reality robotic simulator and robotics labs. The operative experience progresses from case observation to bedside assistant to console surgeon. The role of the console surgeon progresses in a stepwise fashion, and the procedures of radical tonsillectomy, supraglottic partial laryngectomy, and base of tongue resection have been organized as a series of steps. Conclusion: A structured curriculum for training residents in transoral robotic surgery was developed. This training is important for otorhinolaryngology residents to acquire the knowledge and skills to perform robotic surgery safely.

Abstract-A key competency requirement in endovascular surgery is to optimally visualize and utilize pre-shaped catheters to navigate complex vascular anatomy, yet current performance assessment techniques are limited to grading scales based solely on observation. Since most endovascular procedures involve performing fine motor control tasks that require complex, dexterous movements, this paper explores the potential for a standardized, objective, and quantitative means of measuring technical competence based on analysis of the kinematics of endovascular tool tip motions. To accomplish this goal, we recorded catheter tip movement from twenty subjects performing fundamental endovascular tasks in an inanimate model and in a simulation environment with a virtual representation of the same inanimate model. Several motionbased performance measures that have been shown to reliably assess skill in other domains were computed and tested for correlation with data that were obtained from the global rating scale assessment tool. The metrics that quantified movement quality by assessing movement smoothness produced reliable correlations with the observation-based assessment metrics. These objective and quantitative metrics that capture movement quality could be incorporated into future training protocols to provide detailed feedback on trainee performance.

“…Surgical skill assessment and clinical evaluation has predominantly remained subjective [1] and developing quantitative assessment tools has been a topic of considerable importance [2,3]. Medical education has long relied on subjective evaluations or in some cases semi-quantitative (like Likert-scale based) due to the lack of reliable, accurate and stable objective and quantitative performance metrics [4,5].…”

“…Satava [15] notes virtual-simulationbased training has benefitted from the concomitant revolutions of objective assessment of procedural skills and transition from an apprenticeship-based to criterion-based training model. The growing acceptance of virtual simulators stem from ability to (1) Control presentation of stimuli to trainees [16]; (2) Accurately and transparently monitor user responses [12,17]. For example, in the Fundamentals of Laparoscopic Surgery (FLS) program [18], laparoscopic training competency is measured based on metrics such as time to task completion (TTC) [13,16,19], toolpath length precision (TPL) [17,20] and dexterity of motions [21] using standardized box trainers [22,23].…”

Robotic minimally-invasive-surgery (rMIS) is the fastest growing segment of computer-aided surgical systems today and has often been heralded as the new revolution in healthcare industry. However, the surgical performance-evaluation paradigms have always failed to keep pace with the advances of surgical technology. In this work, we examine extension of traditional manipulative skill assessment with deep roots in performance evaluation in manufacturing industries for applicability to robotic surgical skill evaluation. This method relies on defining task-level segmentation of modular sub-procedures called -Therbligs‖ that can be combined to perform a given task. Performance metrics including intra-and inter-user performance variance can by analyzed by studying surgeons' performance over each sub-tasks. Additional metrics on tool-motion measurements, motion economy, and handed-symmetry can be similarly expanded over this temporal segmentation to help characterize performance. Our studies analyzed video recordings of surgical task performance in two settings:First, we examine performance of two representative manipulation exercises (peg board and pick-andplace) on a da Vinci surgical (SKILLS) simulator to afford a relatively-controlled and standardized testbed for surgeons with varied experience-levels. Second task-sequences from real surgical videos were analyzed with a list of predefined -Therbligs‖ in order to investigate its usefulness for real implementation.
