Effective professional education is critical for enhancing the quality and safety of endoscopic practice. This study aimed to objectively evaluate the immediate efficacy of seven distinct specialized endoscopic training courses by comparing participants’ knowledge assessment scores before (pre-test) and immediately after (post-test) the educational intervention. The courses covered a broad range of clinically relevant topics, including diagnostic Upper GI endoscopy with separate modules on the stomach and the esophagus, screening colonoscopy, inflammatory bowel diseases (IBD) with an emphasis on endoscopic management, and two advanced endoscopic trainings: one focused on endoscopic submucosal dissection (ESD) and another on endoscopic ultrasound (EUS).

Seven one-day specialized endoscopy trainings were conducted between 25 January 2025 and 25 October 2025 as part of the EndoAcademy continuous medical education program in Ukraine. Each training followed a unified structure that included: a diagnostic pre-test; theoretical sessions with case sharing and discussion led by expert faculty, covering updated diagnostic criteria and pathology correlation; small-group hands-on training using modern equipment focused on key interventional techniques such as polypectomy, EMR, endoscopic hemostasis, as well as other essential procedural skills; and a post-test to measure immediate learning gains. Only participants who completed both assessments were included, yielding 76 paired data sets. For each group, a paired t-test assessed statistical significance, and Cohen’s d quantified the effect size.

76 participants had completed both tests. Five of the seven trainings demonstrated a statistically significant increase in mean post-training scores (p ≤ 0.003), with mean improvements ranging from 3.35 to 4.22 points. These five trainings also showed a very large effect size (d ≥ 1.52), confirming the strong practical impact of the educational intervention.

Two trainings did not show statistically significant improvement (p > 0.05), and one of them exhibited a small, non-significant decrease in mean score.

The majority of the specialized endoscopic trainings (5 of 7) were highly effective in immediately improving participants’ knowledge based on paired test results. These findings support the value of structured, targeted educational interventions. For the trainings that did not demonstrate a significant effect, several factors may have contributed, including a notably smaller sample size in one group and a higher level of difficulty of the test questions, which may have limited measurable score improvement. These aspects warrant further evaluation to refine both the training content and the assessment methodology for future iterations.
