Surgical procedural map scoring for decision-making in laparoscopic cholecystectomy

Area of Science:

• Surgical Education
• Cognitive Science
• Medical Informatics

Background:

• Assessing surgical expertise is crucial for training and patient safety.
• Cognitive task analysis offers a framework to understand decision-making processes in surgery.

Purpose of the Study:

• To compare decision-based procedural maps between attending surgeons and surgical residents.
• To determine if procedural mapping reveals differences in operative decision-making.

Main Methods:

• Cognitive task analysis framework applied to laparoscopic cholecystectomy (LC).
• Interviews with attendings and residents on operative decision-making.
• Procedural maps generated from interviews and compared using scoring methods.

Main Results:

• Attendings demonstrated significantly more operative steps and crosslinks in their procedural maps compared to residents.
• No significant differences were found in the number of patient or surgeon factors identified.
• Attendings achieved a higher total score on procedural map analysis, indicating greater structural complexity.

Conclusions:

• Procedural map scoring reveals significant differences in structural complexity between attendings and residents.
• This method may serve as a valuable tool for assessing surgical decision-making skills.
