Objective metrics included volume leaked after saline perfusion(leak) and time to complete the anastomosis. Penalty points wereassigned for broken sutures, air knots, locking sutures and failure tomaintain an outside-in to inside-out technique. Leak, time and pen-alties before and after training were compared.

RESULTS: Mean leak for the novice group was 70.4mL �13.7 andean completion time was 18.7 �3 minutes versus 45.3mL �10.6

(p�.01) and 8.5�1 minutes (p�.001) respectively for the expertgroup. Post-training (proficient group), there was significant im-provement in resident leak (46.7mL�6.8; p�.001) and time(14.4�3; p�.01). Leak was similar between the proficient and ex-pert groups (46.7 mL �6.8 vs. 45.3 mL �10.6 respectively; p�.77);

owever, there remained a significant difference for time (14.4�3.0s 8.5�1 minutes respectively; p�0.01). Mean total penalties for theovice group was (84.5�19.7) compared to zero penalties for theroficient and expert groups.

ONCLUSIONS: We report a low cost workshop for teaching sur-ical residents the basic skills of performing vascular anastomosis. Aimple, objective scoring system is described that can differentiateetween a novice, a person who is proficient and an expert at per-orming vascular anastomosis.

NTRODUCTION: Crisis management is acknowledged as key tonsuring patient safety in operating room (OR) practice. Interpro-essional education aims to teach different professions how to workffectively together. In interprofessional simulation-based educationIPSE), debriefing can be challenging, as participants may feel shynd intimidated about reflecting upon their performance in front ofeers from other professions. This study aims to evaluate IPSE crisisesource management training according to the Kirkpatrick model.

ETHODS: Teams consisting of one anesthesia resident/fellow, oneurgical resident/fellow and one circulating OR nurse, underwent

different simulated scenarios with one video-assisted, expertnstructor-lead team debriefing in between. The crisis scenarios usedhybrid simulation, combining a virtual reality laparoscopic trainernd a high-fidelity computer enhanced mannikin in a realistic oper-ting room environment. Immediately after the session participantsvaluated the program using an anonymous questionnaire, ratingheir experience. The questionnaire approached level 1 (Learners’iews on the learning experience) and 2a (modification of attitudesnd perceptions) according to the modified Kirkpatrick model.

ESULTS: Eighteen teams (54 individuals) each participated inwo scenarios and one expert instructor-lead debriefing for a total of6 scenarios and 18 debriefings. All participants, but one nurse,

valuated the training session. d

ONCLUSIONS: IPSE for peroperative crisis resource manage-ent training was feasible and very well received by the 3 professions.xpert instructor-lead team debriefing didn’t appear to be a barrier to

he implementation of routine IPSE crisis resource managementraining. Further studies should investigate the impact of such pro-rams on higher Kirkpatrick levels.

esign and validation of a model for assessment ofrocedural skills in open surgeryeil Rittenhouse MHSc, BASc, Bharat Sharma MD,anil Sonnadara PhD, Alex Mihailidis PhD, PEng,eodor Grantcharov MD, PhDniversity of Toronto, Toronto, ON

NTRODUCTION: Laparoscopy is currently the gold standard forholecystectomy. Recent literature suggests surgical trainees haveimited exposure to open cholecystectomy which may result in sub-ptimal performance in the event of conversion. Furthermore, mostraining and assessment models are designed for laparoscopic chole-ystectomy with limited opportunities for open simulator training.he present study’s purpose was to design an inexpensive model forpen cholecystectomy and validate a performance assessment tool.

ETHODS: The simulator is comprised of a porcine liver and gall-ladder in a mock human abdomen with silicon skin. The assessmentool utilizes inexpensive IR cameras to provide tracking of participantand motions. Ten novice general surgery trainees (�20 cholecystec-omies) and five expert surgeons (> 100 cholecystectomies) com-leted an open cholecystectomy using the simulator. Procedures wereecorded and assessed by a blinded evaluator using a global ratingcale. Tracking data analysis was based on number of movements andotal path length.

ESULTS: Novices (t�36.18 min) completed the procedure sig-ificantly slower than experts (t�19.53 min) (Mann-Whitney’s test�20, p�0.05) and had significantly more hand movements

Mann-Whitney’s test U�20, p�0.05). Analysis of the total globalating scale scores showed a significant difference between novice14/35) and expert (24/35) performance in all categories (Mann-

hitney’s test U�58, p�0.05).

ONCLUSIONS: The present model presents a realistic, low-costool for training and assessment of procedural skills in open chole-ystectomy. The study demonstrated the validity of the IR trackingevice as an objective assessment tool for open surgical skills training.uture training should incorporate this low-cost, highly effectiveraining device into surgical curricula.
