The aim – ​to evaluate the validity of a human chest model for simulation-based training for thoracentesis.

Material and methods. The procedure was performed by participants with different levels of practical skills (students, residents and doctors). The videos were assessed by a skilled surgeon independently. They didn’t know about capacity of the participants. We used a modified checklist as an assessment tool, which was based on the checklist, proposed by the Copenhagen Academy of Medical Education and Modeling.

Results. All 24 participants (16 students, 6 residents, 2 doctors) performed 3 thoracocentesis procedures on the simulation model, the database consisted of 72 videos. The internal consistency of the checklist was sufficient (Cronbach’s α 0.72). The level of inter-expert reliability was significant (κ 0.68 at p<0.001). Experienced participants scored significantly higher scores on each of the three trials than students and residents (H-score for trial #1, 2, 3 – 11.3086, p=0.004; 16.1346, p<0.001; 16.4702, p<0.001, respectively). Based on the method of contrasting groups, the minimum acceptable threshold of points for confirming the level of competence was established (27 and 30 points for students and residents, respectively). Students and residents showed significantly better results after 3 procedures (χ2 Friedman 25.290, p<0.001; 9.238, p=0.01, respectively). Also, students significantly increased their speed of the procedure after completing 3 attempts (χ2 Friedman 22.875, p<0.001).

Conclusion. The totality evidence showed high-level of validation of simulation model which was developed by the initiative group of the FEFU School of Medicine.
