Neurosurgery is a high-stakes surgical specialty where errors can result in significant patient mortality and morbidity. The amount of force applied on the brain simultaneously by the multiple different instruments during complex neurosurgical procedures is a critical safety metric that, to the investigators' knowledge, has not been previously measured in a realistic operative environment. The investigators have therefore developed a simulation platform integrating an ex vivo calf brain and a 3D-printed skull model attached to a force sensor capable of capturing real-time forces applied to the brain. A cross-sectional case series study will be conducted to evaluate the validity of the system. Medical students, neurosurgical residents, neurosurgical fellows, and staff neurosurgeons from four Quebec institutions will be recruited to perform three simulated subpial resections each using our ex vivo calf brain simulation platform. The forces applied by the microscissors, bipolar forceps, and ultrasonic aspirator onto the brain will be captured along with kinematic data. This study aims to establish the face, content, construct, and convergent validity of this ex vivo calf brain force detection system.
NCT07188181
The present study evaluates whether PGY trainees and surgical residents, with or without AI assistance, could accurately identify the presence and anatomical location of the CBD, as well as delineate intraoperative danger zones during LC.
NCT06273579
At the Neurosurgical Simulation and Artificial Intelligence Learning Centre, we seek to provide surgical trainees with innovative technologies that allow them to improve their surgical technical skills in risk-free environments, potentially improving patient operative outcomes. The Intelligent Continuous Expertise Monitoring System (ICEMS), a deep learning application that assesses and trains neurosurgical technical skill and provides continuous intraoperative feedback, is one such technology that may improve surgical education. In this randomized controlled trial, medical students from four Quebec universities will be blinded and randomized to one of three groups (one control and two experimental). Group 1 (control) will be provided with verbal AI tutor feedback based on the ICEMS error detection. Group 2 will be tutored by a human instructor who will receive ICEMS error data and deliver verbal instruction using the same words as the ICEMS. Group 3 will be tutored by a human instructor who will be provided with ICEMS data and will then deliver personalized feedback. The aim of this study is to determine how the method of delivery of verbal surgical error instruction influences trainee technical skill acquisition and transfer. Evaluating trainee responses to AI instructor verbal feedback as compared to feedback from human instructors will allow for further development, testing, and optimization of the ICEMS and other AI tutoring systems.
NCT06714539
The goal of this clinical trial is to learn if patient specific virtual reality (VR) simulations can be used for surgical orthopaedic education in resident and fellow physician populations.
NCT04691206
The goal of this study is to implement and evaluate the need, feasibility and effectiveness of a resident-initiated, step-wise, graduated operative curriculum designed to enhance resident autonomy for laparoscopic cholecystectomy for general surgery residents.
NCT05830786
Immersive virtual reality (IVR) surgical simulators are increasingly being used for learner education. The aim of this randomized controlled trial is to compare the efficacy of IVR to hands-on orthopaedic workshop sessions (such as arthroscopy simulators, cadaveric models, and Sawbones®) in various orthopaedic subspecialties (such as sports, arthroplasty, and spine surgery). Overall, in this multi-stage comprehensive randomized controlled the aim is to assess: 1. If IVR simulation using head-mounted displays (HMD) is superior to the current standard of training for orthopaedic surgery residents and medical students. 2. Determine if it is feasible to incorporate immersive headset virtual reality simulation into residency training programs and medical school curriculums. 3. Assess the longitudinal application of IVR training on medical student and resident surgical education.
NCT04908072
Currently, surgical training is often conducted using the traditional "apprentice model", where a trainee observes a qualified surgeon and learns from him/her, and then the surgeon supervises the trainee performing surgery on a patient. The investigators believe that this conventional model has substantial limitations and drawbacks, making surgical training less efficient and less safe. The investigators will test the hypothesis that intense virtual reality (VR) simulation-based ophthalmic surgical training improves initial acquisition of competence in key stages of manual small incision cataract surgery (MSICS). To do this, the investigators are proposing a randomized multi-country study. This mixed-method study will combine qualitative and quantitative data collection. Orbis International partnered with FundamentalVR to create a manual small incision cataract surgical (MSICS) simulator, using virtual reality software combined with existing gaming technology. The result is a VR simulator available at a fraction of the cost of products currently on the market. This VR simulator will be the subject of this study. All training within the 'educational intervention' of this study will be performed using simulation. There is no testing or surgical training on patients. Study Design: Prospective, investigator-masked education-intervention randomized controlled study of intensive virtual reality (VR) simulation-based surgical education of ophthalmologists in China, Ethiopia, India, Mongolia, Bangladesh, UK and USA. Construct validity study of assessment scores generated by the VR simulator for novices versus experts. Qualitative study of face validity of VR simulator, and acceptability questionnaire survey of users. Purposes of study: To investigate the efficacy of intensive VR simulation-based surgical education using the Orbis-FVR simulator. To examine whether it improves competence, is acceptable and has validity. To assess the construct validity of the VR simulator's assessment capacity.
NCT04700384
Brief Summary: Background: Although surgical experience and technical skill are associated with better patient outcomes, quantitating surgical ability in the operating room is challenging. In surgical education, large datasets generated by high-fidelity virtual reality simulators can be employed by machine learning algorithms to objectively measure trainee performance and competence on expert benchmarks. This allows repetitive practice of surgical skills in safe and risk-free environments with immediate feedback. Our group developed and has a patent pending for an intelligent tutoring system called the Virtual Operative Assistant (VOA). Utilizing an Artificial Intelligence (AI) support vector machine algorithm, the VOA assesses data derived from the NeuroVR (CAE Healthcare) simulator platform and provides individualized audiovisual feedback to improve learner performance during simulated brain tumor resections. The effectiveness of intelligent tutoring systems such as the VOA to the human surgical apprenticeship pedagogy remains to be elucidated. The aim of this study is to compare the effectiveness and educational impact of personalized VOA feedback to expert instruction on medical student's technical skills learning of a virtual reality tumor resection procedure. Specific Aims: 1) To assess if medical students receiving personalized VOA feedback statistically improve their surgical performance when compared to those having (a) no expert instructor feedback or (b) expert instructor-mediated feedback. 2) To outline if different emotions are elicited by the VOA intelligent tutoring system in medical students while performing this achievement task as compared to human instruction

Qualitative Review of Intraoperative teaching and learning
NCT01560494
This study describes the development and validation of a structured training and assessment curriculum (STAC) for a basic laparoscopic procedure. The investigators hypothesized that residents trained using the STAC curriculum would demonstrate superior technical skills in the operating room compared to residents that were trained using a traditional curriculum.
