Background: The purpose of this study was to determine 2-year performance retention and certification exam pass rate after completion of a proficiency-based fundamental laparoscopic skills (FLS) curriculum and subsequent interval training. Methods: Surgery residents (postgraduate year [PGY]1-5, n = 91) were enrolled in an Institutional Review Board approved protocol. All participants initially underwent proficiency-based training on all 5 FLS tasks. Subsequently, available residents were enrolled every 6 months in an ongoing training curriculum that included retention tests on tasks 4 and 5, with mandatory retraining to proficiency if the proficiency levels were not achieved. The final retention test included the actual FLS certification examination for PGY4-5 trainees. Results: A 96% participation rate was achieved for all curricular components during the 2-year study period (PGY3-5, n = 33). Skill retention at retention 1-4 was 83%, 94%, 98%, and 91% for task 4 and 85%, 95%, 96%, and 100% for task 5, respectively. All PGY4-5 (n = 20) residents passed the FLS certification examination, achieving 413 ± 28 total score on the skills portion (passing score ≥270) and demonstrating 92% retention for all 5 tasks. Conclusion: Proficiency-based training with subsequent ongoing practice results in a very high level of skill retention after 2 years and uniformly allows trainees to pass the FLS certification examination.
