Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Setting: Neurosurgical Simulation and Artificial Intelligence Learning Centre, Montreal Neurological Institute.
Participants: Eligible first- and second-year medical students from across the province of Quebec.
Task: Complete removal of a simulated tumour - distinguishable by colour and haptic properties - with minimal bleeding and damage to surrounding healthy brain using two surgical instruments (Cavitron Ultrasonic Aspirator and Bipolar pincers) of the NeuroVR (CAE Healthcare) surgical simulator.
Intervention: A single 75-minute training session, including six virtual subpial tumour resection attempts (five simple practice scenarios and one complex realistic scenario) with assessment and feedback from either:
1. the VOA intelligent tutoring system (Group 2) or
2. a remote-based expert instructor (Group 3)
Both compared to:
3. control group (Group 1) that receives no assessment or performance feedback.
To our knowledge this will be the first study to compare the effectiveness of an AI-powered intelligent tutoring system to expert instruction in the context of medical and surgical virtual reality simulation and assess the emotional response to such instruction. This study aims to begin to identify successful approaches to use this innovative technology in the medical educational curriculum and improve patient outcomes by augmenting safety, efficiency and competency of surgeons and other healthcare providers.

Control Group
Control Group - Baseline Training
25 Participants allocated. Individuals receive introductory information on using the simulator and the scenario. They perform 5 simple subpial tumour resections for practice and have 5 minutes per trial. After each attempt, the student takes a 5-minute break with no assessment or feedback on their performance. On their 6th attempt they have 13 minutes to perform a different realistic scenario.
No interventions assigned to this group
Experimental Group - Virtual Operative Assistance Training
Experimental Group - Virtual Operative Assistance Training
25 participants allocated. Individuals receive the same information, have the same amount of time and perform the same scenarios as the control group. In the 5-minutes between attempts, participant receive the Virtual Operative Assistance Training assessment of their performance and audiovisual feedback.
Virtual Operative Assistant Training
Individuals receive the same basic information, have the same amount of time and perform the same scenarios as the control group. In the 5-minutes between attempts, participant receive the Virtual Operative Assistant assessment of their performance and audiovisual feedback.
Experimental Group - remote-based expert Instructor Training
25 participants allocated. Individuals receive the same information, have the same amount of time and perform the same scenarios as the control group. Meanwhile, a trained instructor observes the participant's on-screen performance, that is live-streamed, remotely. Instructors are senior neurosurgery residents with extensive experience in performing and assessing this scenario. During the 5-minute feedback session, they chat with the student, discussing the performance and help in setting goals for the next trial.
