The Role of Anxiety in Simulation-Based Dexterity and Overall Performance: Does It Really Matter?

BACKGROUND: Essential Skills in the Management of Surgical Cases (ESMSC) is an international undergraduate surgical masterclass which combines ex vivo, dry lab and high fidelity in vivo simulation-based learning (SBL). It consists of 32 stations of skills-based learning, including open reduction internal fixation (ORIF) of fractures. Current literature suggests early involvement in skills-based learning at the undergraduate level is vital. AIMS: To compare students' dexterity and skills-based performance with demographic and educational background parameters. METHODS: 112 medical students from European Union countries including the United Kingdom, Germany, Greece, Cyprus, Germany, and Bulgaria were selected from a competitive pool of candidates to attend the course. Students undertook ORIF in an ex vivo swine model, and in a simulated fracture on a bamboo rod. Skills-based performance was assessed by two consultant surgeons with validated direct observation of procedural skills (DOPS) forms. Anxiety was self-assessed using the Westside Anxiety Scale prior to the ORIF stations. Dexterity was measured with the O'Connor tweezer dexterity test. RESULTS: Female students had significantly higher dexterity scores (median difference 7, p =.003). Right-handed students achieved higher dexterity than left-handed students (median difference 7, p =.043). There was no difference in students' performance across different medical schools, and across year groups (p <.05 for any correlation). Self-reported anxiety was not correlated with high fidelity skills-based performance (r = 0.032, p =.74). CONCLUSION: Anxiety does not seem to play a significant role in Simulation Skills-Based learning. Undergraduate surgical curricula should incorporate SBL-based modules to enhance practical skills learning and motivate future orthopedic surgeons.
