Background Competency in surgical training is a topic of much recent discussion, with concern regarding the adequacy of current training schemes to achieve competency. Most programmes use caseload and primary operator rates to assess trainee progression. Some trainees still lack technical competence even when recommended procedural numbers are met. It is possible that current measures of individual's capabilities used in surgical education are outdated. Methods Logbook data of New South Wales general surgical trainees between 2010 and 2012 was obtained through General Surgeons Australia. The top 10 most common operations recorded in trainee logbooks were identified. Individual trainee data were grouped by the surgical education and training year and primary operator versus assistant experience. The data were analysed focusing on the primary operator rate, comparing between trainee levels to identify progression. Results A total of 183 319 operations were recorded in New South Wales general surgery trainee logbooks. A positive association was demonstrated between trainee seniority and primary operator rates for the most common procedures, indicating trainee's continual progression in experience as they advance. However, laparoscopic inguinal hernia repair, oversew of gastroduodenal ulcer, open cholecystectomy and right hemicolectomy showed poor primary operator rates among trainees regardless of trainee year, despite these operations being among the 10 most common. Conclusion General surgical trainees accumulate operative experience with progression through the surgical education and training programme, highlighting expected technical progression and competency of trainees for common procedures. For less common or more complicated procedures, the use of entrustable professional activities and accompanying simulation training could be used to achieve the necessary technical expertise.
