Resuscitative hysterotomy is a daunting and rarely performed procedure in the emergency department (ED). Given the paucity of clinical exposure to this intervention, resuscitative hysterotomy is an ideal opportunity for simulation-mediated deliberate practice. The authors propose a novel training program using a homegrown, realistic, simulation device as a means to practice resuscitative hysterotomy. Two high-fidelity, tissue-based task-trainer models were constructed and tested on a convenience sample of 14 emergency medicine (EM) residents. The simulated human placenta, bladder, amniotic sac, and uterus were constructed through the use of porcine skin, porcine stomach, transparent plastic bag, Foley tubing, and squid mantle, all secured with nylon sutures. A Gaumard S500 Articulating Newborn was inserted in the simulated uterus, and the entire model was placed into a Gaumard S500 Childbirth Simulator. Each model required less than 1 h for assembly. Emergent hysterotomy was first demonstrated by an EM faculty facilitator, followed by hands-on deliberate practice. Formal feedback on the learners' self-reported confidence and satisfaction levels was solicited at the end of the workshop through a survey previously cited for use with a low-fidelity resuscitative hysterotomy. Quantitative evaluation of the simulated training session was extracted through a 5-item questionnaire using a 5-point Likert-type scale (i.e., from 1, strongly disagree, to 5, strongly agree). Item scores were added for a cumulative total score, with a possible maximum score of 25 and minimum score of 5. Responses were overwhelmingly positive [24.13 (± 1.36)]. Qualitative feedback was extracted from the survey through open-ended questions; these responses highlighted learners' appreciation for hands-on practice and the development of a novel, tissue-based simulation task trainer. All participants recommended the training session be available to future learners. Resuscitative hysterotomy is a high-stakes, low-frequency procedure that demands provider practice and confidence. Our hybrid, tissue-based hysterotomy model represents a feasible opportunity for training. The model is cost conscious, easily reproducible, and portable and allows for ample deliberate practice., Competing Interests: Dr. Zhang is a triple graduate of Tufts University, where he received a Bachelor of Science in Mechanical Engineering, Masters in Biomedical Engineering, as well as a Medical Doctorate Degree within 9 years of rigorous and interdisciplinary training. Despite this condensed training period, Dr. Zhang distinguished himself among his peers through his dedication towards medical education and technologic innovation, as evident from his involvement in medical education course developments, teaching opportunities, and innovative medical inventions. Throughout his career, Dr. Zhang has been consistently and substantively involved with education, teaching, and simulation training. He has published numerous articles on simulation modules, debriefing techniques, augmented reality as an interactive learning platform, and the use of gamification frameworks in a simulated environment to tackle pedagogical and patient safety challenges. Dr. Zhang is currently the principal investigator of a study that aims to develop and implement simulation-based training to improve orthopedic distal radius fracture reductions in emergency department (ED) patients. Dr. Zhang is currently a clinical instructor and assistant clerkship director at Thomas Jefferson University, where he will be completing his education fellowship as well as the rigorous Master of Health Profession Education program at the University of Illinois, Chicago. Dr. Zhang recently received a certificate of completion for the prestigious American College of Emergency Physicians (ACEP) Teaching Fellowship and the Pennsylvania Medicine Simulation Facilitator’s Course during his first year of fellowship.The Institutional Review Board (IRB) has evaluated the involvement of human subjects in the proposed research study entitled: “A Novel Building a Realistic High Fidelity BioSimulation Task Trainer for the Deliberate Practice of Resuscitative Hysterotomy” (Departmental) 45 CFR 46.101 (1-educational research, 2-survey; no IDs) control #18E.267 to be exempt from IRB review on 05/03/2018 pursuant to Title 45 Code of Federal Regulations Part 46.101(b) governing exempted protocol declarations.
