Immersive Virtual Reality Environment for Complex Cognitive Skills Curricular Training in Liver Surgery

Investigators hypothesize that a virtual reality (VR) environment enhances general surgery residents' performance compared to Desktop Interface (DI)-based visualization of 3D models in decision making for patients with liver tumors. To determine this, a proficiency-based stepwise training curriculum for preoperative planning has been developed using both modalities. The overall objective of the curriculum is that by the end of the training program, residents would be able to formulate a treatment plan for patients with liver tumors.

Exclusion criteria

  • Residents of other specialties

Treatment and study plan

Clinical decision making based on visualizing liver 3D models in Virtual Reality (VR) environment or via a Desktop Interface (DI)

Behavioral

Visualizing 3D models of livers for preoperative surgical planning via two different environment: DI and VR in sequential order

Primary outcomes

  1. Residents' decision-making accuracy

    Time frame: Immediately after completing the educational intervention

    Residents' decision-making accuracy when reviewing patient data and 3D liver models using DI or VR, measured by comparing their performance to experts' opinions.

    The measurement tool will be a questionnaire consisting of ten questions, rate of correct answers will be recorded (e.g. 8/10 correct answers) and higher scores mean a better outcome.

    Minimum score=0; Maximum score=10.

Secondary outcomes

  1. Cognitive knowledge retention

    Time frame: Baseline and immediately after completing the educational intervention

    Retention of knowledge assessed by validated multiple choice questions. Questionnaire consisted of 15 questions will be used, rate of correct answers will be recorded (e.g. 8/15 correct answers), and higher scores mean a better outcome.

    Minimum score=0; Maximum score=15.

  2. Residents' scores in recognizing intrahepatic structures and liver segments

    Time frame: Immediately after completing the educational intervention

    Assessed by recognizing intrahepatic structures and 8 liver segments. Questionnaire consisted of 22 questions will be used, rate of correct answers will be recorded (e.g. 8/22 correct answers), and higher scores mean a better outcome.

    Minimum score=0; Maximum score=22.

  3. Time needed to devise a surgical plan using the DI or VR platform

    Time frame: Immediately after completing the educational intervention

    Assessed by total time needed to make decision for 10 patient cases in minutes
