Brief Summary

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

Outcome Measures

Primary Outcomes (2)

  • Change in procedural performance .

    Performance in each practice attempt is measured utilizing raw data from the simulator that is used for assessment by previously established AI algorithms on validated metrics.

    Day of Study

  • Change in learning

    Performance on the complex realistic scenario is evaluated by expert instructors using the Objective Structured Assessments of technical Skills (OSATS) Visual Rating Scale (weighted at 50%) and the AI assessment algorithms (weighted at 50%) creating a composite performance score.

    Day of Study

Secondary Outcomes (2)

  • Difference in the strength of emotions elicited

    Day of Study

  • Difference in cognitive load

Control Group

NO INTERVENTION

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.

Experimental Group - Virtual Operative Assistance Training

EXPERIMENTAL

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.

Behavioral: Virtual Operative Assistant Training

Experimental Group - remote-based expert Instructor Training

EXPERIMENTAL

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.
