Technology for Psychomotor Skills Testing in Endoscopic Surgery

Area of Science:

• Surgical Education and Training
• Medical Device Development
• Human Factors Engineering

Background:

• Psychomotor skills are critical for surgical aptitude and practice.
• Objective assessment tools are needed for surgical trainee selection.
• Existing methods for evaluating endoscopic surgical skills are limited.

Purpose of the Study:

• To develop and validate microprocessor-controlled psychomotor testers for endoscopic surgery.
• To evaluate the psychomotor abilities of surgical trainees.
• To provide objective, real-time scoring for endoscopic tasks.

Main Methods:

• Development of two novel psychomotor testers: DEPT (Dundee Endoscopic Psychomotor Tester) for single-handed tasks and ADEPT (Advanced Dundee endoscopic Psychomotor Tester) for bimanual tasks.
• Utilizing microprocessor control for objective, real-time performance scoring.
• Conducting studies with medical students to assess feasibility and skill differences.

Main Results:

• The developed testers provide objective scoring systems with face validity for the endoscopic environment.
• Objective evaluation of endoscopic task performance is feasible.
• Significant differences in psychomotor abilities were observed among medical students.

Conclusions:

• Microprocessor-controlled psychomotor testers are effective tools for evaluating endoscopic surgical skills.
• These tools can aid in the aptitude-based selection of surgical trainees.
• Objective assessment of psychomotor abilities is crucial for ensuring sound surgical practice.
