Standardized simulation-based training can improve CVC insertion proficiency, even among trainees with previous experience sufficient to have been deemed competent in the procedure. Improved performance at simulation-based testing may translate to improved outcomes of CVC placement by trainees.

BackgroundConducting simulations of rapidly decompensating patients are a key part of internal medicine (IM) residency training. Traditionally, mannequins have been the simulation tool used in these scenarios.ObjectiveTo compare IM residents’ performance and assess realism in specific-simulated decompensating patient scenarios using standardized patients (SPs) as compared to mannequin.MethodsNineteen IM residents were randomized to undergo simulations using either a mannequin or an SP. Each resident in the two groups underwent four different simulation scenarios (calcium channel blocker overdose, severe sepsis, severe asthma exacerbation, and acute bacterial meningitis). Residents completed pretest and post-test evaluations as well as a questionnaire to assess the reality perception (realism score).ResultsNine residents completed mannequin-based scenarios, whereas 10 completed SP-based scenarios. Improvement in the post-test scores was seen in both groups. However, there were significantly higher post-test scores achieved with SP simulations in three out of the four scenarios (P=0.01). When compared with the mannequin group, the SP simulation group showed a significantly higher average realism score (P=0.002).ConclusionsApplying SP-based specific-simulation scenarios in IM residency training may result in better performance and a higher sense of a realistic experience by medical residents.
