Impact of Trainee Participation on Inguinal Hernia Repair Outcome: A Study Based on the Swedish Hernia Register

Objective: The aim of this study was to investigate whether differences in postoperative outcome exist between open inguinal hernia repairs performed by surgical trainees and those performed by specialist surgeons. Summary of Background Data: Inguinal hernia repair is the prototype educational surgical procedure. The impact of trainee participation on postoperative outcome is still controversial and despite earlier studies no reliable hernia-specific data exist. Methods: The study cohort was based on the Swedish Hernia Register and consisted of 61,161 cases of male patients aged 18 years and older with open anterior mesh repair of a primary inguinal hernia between January 1, 2002, and December 31, 2014. The study cohort was selected to represent the typical trainee procedure in Sweden. Primary outcome measures were reoperation due to hernia recurrence and postoperative 30-day complications. Results: Procedures with longer operating times were at a higher risk for reoperation when performed by supervised trainees [57 to 72 minutes: hazard ratio (HR) 1.55, 99% confidence interval (99% CI) 1.05–2.27] or unsupervised trainees (57 to 72 minutes: HR 1.60, 99% CI 1.18–2.17;>72 minutes: HR 1.72, 99% CI 1.25–2.37). The same was true for specialist and trainee-assisted specialists with operating times
