简要总结
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.

研究组 & 干预措施
Group A
Group A received first five patient cases and 3D models via DI and another five cases in the VR environment
干预措施: Clinical decision making based on visualizing liver 3D models in Virtual Reality (VR) environment or via a Desktop Interface (DI) (Behavioral)
Group B
Group B received first five patient cases and 3D models via VR and another five cases in the DI.
干预措施: Clinical decision making based on visualizing liver 3D models in Virtual Reality (VR) environment or via a Desktop Interface (DI) (Behavioral)
结局指标
主要结局
Residents' decision-making accuracy
时间窗: 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.
次要结局
- Cognitive knowledge retention(Baseline and immediately after completing the educational intervention)
- Residents' scores in recognizing intrahepatic structures and liver segments(Immediately after completing the educational intervention)
- Time needed to devise a surgical plan using the DI or VR platform(Immediately after completing the educational intervention)
