Rasmussen's model of human behavior in laparoscopy training

Area of Science:

• Surgical Education
• Human Factors Engineering
• Medical Simulation

Background:

• Virtual reality (VR) training is established in aviation but requires definition for minimally invasive surgery (MIS).
• Standardized objectives, needs, and means for VR training in MIS are currently lacking.
• Human behavior models offer a potential framework for developing effective MIS VR training.

Purpose of the Study:

• To introduce Rasmussen's model of human behavior as a framework for defining MIS VR training.
• To establish objectives, needs, and means for VR training in MIS based on human behavior levels.
• To guide the development of comprehensive VR laparoscopy trainers.

Main Methods:

• Applying Rasmussen's three levels of human behavior: skill-based, rule-based, and knowledge-based.
• Identifying specific behaviors required for safe laparoscopy at each level.
• Analyzing current VR laparoscopy simulators in relation to these behavior levels.

Main Results:

• Most current laparoscopy simulators focus on skill-based behavior training.
• Training knowledge-based behavior, particularly during surgical complications, is crucial for enhancing safety.
• Increasing training complexity from skill-based to knowledge-based behavior elevates the cost and complexity of training tools.

Conclusions:

• Rasmussen's model can integrate skill-, rule-, and knowledge-based behavior training in MIS VR simulators.
• Successful application in aviation demonstrates the value of human behavior models in simulator training.
• Understanding surgeon behavior is a foundational step towards developing advanced laparoscopy simulators.
