Simulator/Device Validation

EventDoc™ System

Inconsistencies and omissions in the documentation of OR procedures can result in harm to patients and increased costs of care. The Medical Emergency Black Box Information Systems (MEBBIS) project aims to evaluate, select, and modify existing technology and devices for their application in the proposed mission of capturing multiple data elements during a simulated emergency.


HD Video Endoscopy

High-definition (HD) video technologies have been widely adopted in recent years replacing standard-definition (SD) technologies in endoscopic instrumentation. These technologies offer greater pixel resolution, but whether this translates to an improvement in clinically relevant measures has yet to be tested. These measures include spatial image resolution, color discrimination, and contrast sensitivity. WISH researchers aim to evaluate and compare the quality of these measures in HD and SD video-endoscopic units.


Simulator Based Cardiac Surgery Training

UW Medicine is involved in a multi-institutional cardiac surgery training program aimed towards improving comprehension and demonstrating proficiency in basic cardiac surgical skills. Competence in these skills requires extensive and deliberate practice with a thorough understanding of instrument use, tissue handling, and managing adverse scenarios. With the use of simulated tissues and the high-fidelity Ramphal Cardiac Surgery Simulator, residents are able to approach a realistic platform to perfect technique and practice cardiac surgical procedures. Upon completion of training, residents will be able to perform all required surgical steps for the institution and completion of various cardiac procedures.


Skills Acquisition in Single Incision Laparoscopic Surgery (SILS)

Single Incision Laparoscopic Surgery (SILS) is a modification of this standard technique in minimally invasive surgery.  This newer method entails performing the same operations, but using new FDA-approved instruments that allow operations to be performed through one small (2cm) incision rather than through multiple 1-2cm incisions.  These new SILS techniques may offer patients an even quicker recovery with an improved cosmetic result compared to standard laparoscopic surgery.  The amount and type of training needed to use these newer SILS instruments and techniques is, however, not known. WISH researchers are investigating how these skills are acquired using standardized surgical simulators with these new instruments.  The data may help determine what type and how much training should be required before surgeons can be deemed qualified to perform these new procedures safely on actual patients.


Validation Study of Simpraxis Laparoscopic Cholecystectomy Surgical Trainer

Warm-up exercises have been shown to improve subject performance on designated skills in multiple professions and some have hypothesized that because surgical performance is both technical and cognitive, practice exercises stimulating both sensori-motor and cognitive centers in our brain may aid in surgical performance and error reduction.  WISH researchers are currently investigating use of an online training module for preparation in the area of Laparoscopic Cholecystectomy using a procedure specific curriculum.
