Summary
Virtual patients significantly improved surgery students' history-taking skills. However, other clinical competencies were not substantially enhanced, suggesting cautious implementation of such educational tools.
Area of Science:
- Medical Education
- Surgical Training
- Digital Health Tools
Background:
- Undergraduate surgery education faces challenges in developing comprehensive clinical skills.
- The integration of technology, such as virtual patients, is increasingly explored to enhance learning outcomes.
Purpose of the Study:
- To evaluate the impact of virtual patient simulations on surgical clerks' clinical skills.
- To assess the effectiveness of virtual patients in improving specific competencies relevant to surgical problem-solving.
Main Methods:
- A randomized controlled trial involving 48 surgery clerks over 7 weeks.
- An intervention group utilized 14 simulated abdominal pain cases, while a control group did not.
- Competencies were assessed via a structured paper-based exam.
Main Results:
- A significant improvement was observed in history-taking skills (P < 0.001) for the intervention group.
- No significant improvements were noted in the use of diagnostic tests, differential diagnoses, management planning, or factual knowledge.
- Virtual case exam scores showed poor correlation with written exam performance.
Conclusions:
- Virtual patients are effective tools for enhancing medical students' history-taking abilities.
- Educators should maintain a critical perspective on the broad impact of computer-based learning tools in surgery.
- Over-reliance on virtual patient technology without considering other pedagogical methods may lead to unmet expectations.
