Simulation-based training improves polypectomy skills among practicing endoscopists

Abstract

Background and study aims Practicing endoscopists have variable polypectomy skills during colonoscopy and limited training opportunities for improvement. Simulation-based training enhances procedural skill, but its impact on polypectomy is unclear. We developed a simulation-based polypectomy intervention to improve polypectomy competency.

Methods All faculty endoscopists at our tertiary care center who perform colonoscopy with polypectomy were recruited for a simulation-based intervention assessing sessile and stalked polypectomy. Endoscopists removed five polyps in a simulation environment at pretest followed by a training intervention including a video, practice, and one-on-one feedback. Within 1–4 weeks, endoscopists removed five new simulated polyps at post-test. We used the Direct Observation of Polypectomy Skills (DOPyS) checklist for assessment, evaluating individual polypectomy skills, and global competency (scale: 1–4). Competency was defined as an average global competency score of ≥ 3.

Results 83 % (29/35) of eligible endoscopists participated and 95 % (276/290) of planned polypectomies were completed. Only 17 % (5/29) of endoscopists had average global competency scores that were competent at pretest compared with 52 % (15/29) at post-test (P = 0.01). Of all completed polypectomies, the competent polypectomy rate significantly improved from pretest to post-test (55 % vs. 71 %; P < 0.01). This improvement was significant for sessile polypectomy (37 % vs. 65 %; P < 0.01) but not for stalked polypectomy (82 % vs. 80 %; P = 0.70).

Conclusions Simulation-based training improved polypectomy skills among practicing endoscopists. Further studies are needed to assess the translation of simulation-based education to clinical practice.
