“…[5][6][7][8] Also, in fields other than ophthalmology, surgical experience is generally gained during actual operations, and surgical education is a problem. The surgical simulators are not only useful for ophthalmologists to learn operating techniques, but also for physicians in other fields.…”

“…8 Other 'simulation' technologies have been used to teach and evaluate performance of different skills. [9][10][11] The Anesthesia Simulation System provides a realistic operating room experience that offers opportunities for working through a situation structured to challenge a student at the expected level of competence. The sessions can be easily videotaped which allows the provision of constructive feedback to both students and faculty instructors.…”

225Purpose: To examine the validity and reliability of performance assessment of undergraduate students using the anesthesia simulator as an evaluation tool.Methods: After ethics approval and informed consent, 135 final year medical students and 5 elective students participated in a videotaped simulator scenario with a Link-Med Patient Simulator (CAE-Link Corporation). Scenarios were based on published educational objectives of the undergraduate curriculum in anesthesia at the University of Toronto. During the simulator sessions, faculty followed a script guiding student interaction with the mannequin. Two faculty independently viewed and evaluated each videotaped performance with a 25-point criterion-based checklist. Means and standard deviations of simulatorbased marks were determined and compared with clinical and written evaluations received during the rotation. Internal consistency of the evaluation protocol was determined using inter-item and item-total correlations and correlations of specific simulator items to existing methods of evaluation.Results: Mean reliability estimates for single and average paired assessments were 0.77 and 0.86 respectively. Means of simulator scores were low and there was minimal correlation between the checklist and clinical marks (r=0.13), checklist and written marks (r=0.19) and clinical and written marks (r=0.23). Inter-item and item-total correlations varied widely and correlation between simulator items and existing evaluation tools was low.Conclusions: Simulator checklist scoring demonstrated acceptable reliability. Low correlation between different methods of evaluation may reflect reliability problems with the written and clinical marks, or that different aspects are being tested. The performance assessment demonstrated low internal consistency and further work is required. Conclusion : La cotation selon les critères liés au simulateur a démontré une fiabilité acceptable. Une faible corrélation entre différentes méthodes d'évaluation peut traduire des problèmes de fiabilité avec les notes obtenues aux examens écrits et cliniques, ou le fait que d'autres aspects sont testés. L'évaluation de la performance a démontré une faible conformité interne et la nécessité d'expérimentation ultérieure.

The training of a surgeon includes the acquisition of a number of characteristics. These include a cognitive knowledge base, problem formulation and decisionmaking abilities, appropriate psychosocial relationships, and other attributes that can be measured with objective testing, such as national board or specialty certifying examinations. Perhaps most critical to the surgeon, however, are the core technical skills of the profession. A battery of sophisticated devices is being created to teach and provide objective evaluations of the trainee's technical abilities. These innovative state-of-the-art simulation devices, used to teach basic skills and surgical tasks through repetitive proctored challenges, will enable detection and analysis of surgical errors and near miss incidents without risk to patients. As with flight simulation, near miss detection capabilities anticipate potential errors before they occur and prevent resulting complications. In collaboration with a number of otolaryngology residency programs, we have developed a comprehensive training curriculum, based on complementary simulation tools and several perceptual and spatial ability test instruments, to provide objective metrics for assessing the technical skills of trainees. These tools include an endoscopic sinus surgery simulator for procedural training, and the Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) system for basic surgical skills training. Technical errors are identified, quantified, and used to monitor surgical performance, after which the metrics are used for outcome analysis, for the purpose of improving patient safety. Validated metrics include time-to-completion, errors, economy of motion, and psychomotor tracking. Endoscopic sinus surgery is a suitable operation substrate, since it is a frequently performed procedure (more than 300,000 times annually in the United States.) and carries a significant risk of injury to the delicate neighboring eye and brain structures. The endoscopic sinus surgery simulator (ES3) is an advanced surgical simulation device based largely on jet pilot flight simulation, and provides the trainee with appropriate levels of challenge and instruction. ES3 validation studies are reported here, along with a description of the World Wide Web-based Intelligent Information Interface (WI3) simulation database.
