Physician Versus Nonphysician Instruction: Evaluating an Expert Curriculum-Competent Facilitator Model for Simulation-Based Central Venous Catheter Training.

Introduction Healthcare simulation supports educational opportunities while maintaining patient safety. To reduce costs and increase the availability of training, a randomized controlled study evaluated central venous catheter (CVC) insertion training in the simulation laboratory with nonphysician competent facilitators (NPCFs) as instructors. Method A group of learners naive to central line placement participated in a blended curriculum consisting of interactive online materials and simulation-based training. Learners were randomized to training with NPCFs or attending physician faculty. The primary outcome was simulated CVC insertion task performance, graded with a validated checklist by blinded physician reviewers. Learner knowledge and satisfaction were also evaluated. Analysis was conducted using noninferiority testing. Results Eighty-five students, 11 attending physicians, and 7 NPCFs voluntarily participated. Noninferiority testing of the difference in CVC insertion performance between NPCF-trained learners versus physician-trained learners found no significant difference [rejecting the null hypothesis of inferiority using an 8% noninferiority margin (P < 0.01)]. In addition, there was no difference found between the 2 groups on pre/post knowledge scores, self-reported learner comfort, course satisfaction, or instructor satisfaction. Conclusions An introductory CVC curriculum can be taught to novice learners by carefully trained and supported NPCFs and achieve skill and knowledge outcomes similar to learners taught by physicians.
