Objective:
Increasingly, medical schools integrate clinical skills into early didactic coursework. The Stop the Bleed® Campaign emphasizes prehospital hemorrhage control to reduce preventable deaths; however, this course overlooks team interactions. We assessed the impact of high-fidelity simulation during medical student orientation on identification and treatment of life-threatening hemorrhage in a team setting.
Design:
In this mixed method, prospective pre-, post-, and follow-up survey analysis assessing student knowledge and attitudes, student teams encountered a standardized patient in a prehospital environment with pulsatile bleeding from an extremity wound. Individual students completed surveys assessing previous experience, willingness and ability to assist bleeding person(s), and knowledge and attitudes about tourniquets. Postscenario, faculty preceptors made qualitative observations on teamwork.
Setting:
Medical student orientation at a tertiary care academic medical center with long-term follow-up.
Participants:
Medical students (N = 150).
Results:
Ninety students (60%) completed both pre- and postsimulation questionnaires. Sixteen (17%) students had previous tourniquet training experience although none had applied a tourniquet outside of training. Postsimulation, students reported increased likelihood of providing treatment until additional help arrived (p = 0.035), improved ability to identify life-threatening hemorrhage (p < 0.001), and more favorable opinions about tourniquet use (p < 0.001) and potential for limb-salvage (p = 0.018). Long-term follow-up respondents (n = 34, 23%) reported increased ability to identify life-threatening hemorrhage (p = 0.010) and universal willingness to intervene until additional help arrived. Follow-up survey responses elicited themes in hemorrhage control including recognition of the importance of continuous pressure, appropriate use of tourniquets, a desire for repeated team training, and the recognition of clerkship rotations as an optimal setting for skill reinforcement. Preceptors noted variable team responses but uniformly endorsed the exercise.
Conclusions:
High-fidelity bleeding simulation during medical student orientation improved students' knowledge and attitudes about treating life-threatening hemorrhage and served as an introduction to team-based emergency care. Future studies should further explore team training and hemorrhage control education.
