BackgroundSeptic shock resuscitation bundles have poor compliance worldwide partly due to a lack of knowledge and clinical skills. High-fidelity simulation-based training is a new teaching technology in our faculty which may improve the performance of medical students in the resuscitation process. However, since the efficacy of this training method in our institute is limited, we organized an extra class for this evaluation.PurposeThe aim was to evaluate the effect on medical students’ knowledge and confidence levels after the high-fidelity medical simulation training in septic shock management.MethodsA retrospective study was performed in sixth year medical students during an internal medicine rotation between November 2015 and March 2016. The simulation class was a 2-hour session of a septic shock management scenario and post-training debriefing. Knowledge assessment was determined by a five-question pre-test and post-test examination. At the end of the class, the students completed their confidence evaluation questionnaire.ResultsOf the 79 medical students, the mean percentage score ± standard deviation (SD) of the post-test examination was statistically significantly higher than the pre-test (66.83%±19.7% vs 47.59%±19.7%, p<0.001). In addition, the student mean percentage confidence level ± SD in management of septic shock was significantly better after the simulation class (68.10%±12.2% vs 51.64%±13.1%, p<0.001). They also strongly suggested applying this simulation class to the current curriculum.ConclusionHigh-fidelity medical simulation improved the students’ knowledge and confidence in septic shock resuscitation. This simulation class should be included in the curriculum of the sixth year medical students in our institute.
