Background: Intercostal chest drain (ICD) insertion is a skill that medical trainees lack confidence in performing. This study explores the impact of a national programme of Simulation-Based Mastery Learning (SBML) on procedural confidence, including the impact of time intervals between booster sessions and interim clinical experience.
Methods: Internal Medicine Trainees in Scotland were surveyed about confidence and clinical experience with ICD insertion before and immediately after SBML and booster session. Data were matched and analysed using paired sample t-tests. Short interval and long interval groups were compared using Student's unpaired t-test. The impact of interim clinical experience was assessed using Analysis of Variance.
Results: Mean confidence in ICD insertion rose following SBML, fell between initial and booster session, and increased again following booster session (P = < 0.001). 33 of 74 trainees had successfully inserted an ICD between sessions. Fall in confidence was unaffected by the time interval between training sessions, but was mitigated by interim clinical experience.
Conclusions: SBML boosts trainee confidence in ICD insertion. However, there is evidence of confidence decay, possibly due to a lack of clinical experience between sessions. More research is needed to explore barriers to transfer of skills from simulated to real-world environments.
