Trainees' surgical activity and opportunity to transfer after simulation-based training.

Introduction: Simulation-based surgical training (SBST) is predicated on the assumption that trainees transfer their acquired skills and competencies into the operating room. Research on transfer of surgical training has focused on trainees' performance improvements and not on their actual opportunity to transfer their trained skills.

Methods: This was a retrospective study conducted using data on surgical procedures performed by first-year trainees in abdominal surgery, gynaecology and urology in the Central Denmark Region.
