  1. Validation of Open Inguinal Hernia Repair Simulation Model A Randomised Controlled Educational TrialKhatib M, HaldN, BrentonH, Sarker S, Standfield N, Ziprin P, Kneebone R, Bello FImperial College London Association for Surgical Education Surgical Education Week 24th April 2013

  2. Introduction • Surgical simulation brought to the forefront of surgical training • Technological advances • Importance of surgical safety • Limitation in surgical trainee exposure • EWTD • Duty hour restrictions • Abundance of laparoscopic/ endovascular simulators • Development of Hernia Repair Open Surgical Simulation (HeROSS) model

  3. Method Recruitment Clinical Years Medical students invited to participate Volunteers screened Exclusion criteria implemented Block Randomisation Pre-intervention MCQ Assessment 1. Post-intervention MCQ 2. Viva Group 1: Interactive Simulation Performing or assisting in an open inguinal hernia repair Previous bachelor degree in anatomy Anatomy demonstrator Group 2: Non-interactive Simulation Intervention Group Group 3: Video Tutorial Group 4: Control Group

  4. Method • Three separate one hour learning sessions • Scenario given to candidates • All in one week • Assessment one day after final learning session

  5. Method • Interactive Simulation

  6. Method • Video Tutorial

  7. Method • Control Group • Internet access • Quick access to all surgical procedure textbooks and mini-textbooks available in Imperial College Library • Anatomy handouts from commonly used anatomy textbooks and atlases

  8. Results

  9. Results • 54 students completed study • Group 1 n=15 • Group 2 n=15 • Group 3 n=12 • Group 4 n=14

  10. Results

  11. Results – Comparison Between Groups

  12. Conclusions • Statistically significant Improvement in anatomical and procedural knowledge from using the interactive simulation model • Vital role of simulation as an adjunct in modern surgical training • Open surgical procedural knowledge a pre-requisite to laparoscopic surgery • Envisage online virtual theatre with ability to do multiple core index procedures

  13. Future Research • Recruitment of surgical trainees ongoing • Addition of recorded assessment on hernia model

  14. Thank you
