A Cardiac Surgery Mini-Elective Increases Specialty Knowledge Acquisition Among Pre-Clinical Medical Students

Abstract

Background: The introduction of integrated thoracic surgery residency programs has led to increased recruitment efforts of medical students to pursue a career in cardiac surgery. With little representation of cardiac surgery in medical school curriculum, we assessed a cardiac surgery mini-elective's efficacy in improving perceived knowledge among medical students. Methods: Preclinical medical students were offered the opportunity to participate in a cardiac surgery mini-elective, which consisted of five 2-hour sessions. These sessions consisted of didactic and simulation components and covered topics including cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenation (ECMO), aortic disease, aortic valve replacement (AVR), transplant and left ventricular assist devices (LVAD), and coronary artery bypass grafting (CABG). Students completed pre- and post-session surveys describing their perceived knowledge in these topics. Results: Overall, 22 students completed at least one session of the mini-elective. Fourteen (73.7%) of the students were male. Fifteen (68.2%) students completed at least three out of five sessions. The post-session survey responses showed significantly higher perceived knowledge compared with pre-session responses for all survey prompts of all five sessions. The CPB/ECMO and aortic disease sessions showed the greatest increase in post-session familiarity and perceived knowledge after the session (P < 0.001) compared with the CABG, AVR, and transplant/LVAD sessions (P < 0.05). Conclusions: Beyond developing interest in cardiac surgery, these data indicate that a well-planned didactic and surgical simulation program may build confidence in students' knowledge of various cardiac surgical topics. Further studies will need to address how this increase in perceived ability lasts over time and impacts career selection.

Knowledge and Perception of Cardiac Surgery Among Medical Students in the Western Region of Saudi Arabia

“…One study used session-based surveys of common cardiac surgery topics like extra-corporal membrane oxygenation (ECMO) and cardiopulmonary bypass (CBP) to evaluate the effectiveness of cardiac surgery mini-elective sessions in improving undergraduates' knowledge about the specialty. The study found a significant improvement when comparing the results of pre- and post-session surveys [ 8 ]. The results of a similar study showed an 81% rise in interest in the field of cardiac surgery [ 3 ].…”
