“…In a previous study, an umbilical catheterization hybrid model required a longer time to catheter placement compared with a synthetic model. 10 Last, we did not use a previously validated MCQ knowledge test. High-stakes MCQ tests require multiple raters and large numbers of participants to assure reliability and validity, and have not been published for umbilical catheterization knowledge assessment.…”

“…Fidelity gaps include vessel compliance, umbilical cord surface texture, and tactile sensations experienced during umbilical cord manipulation. In umbilical catheter hybrid model simulator studies it was concluded that hybrid models with higher physical and functional fidelity are preferred for training by pediatric residents . The impact of these fidelity gaps on educational training outcomes has not been studied and may represent barriers to reliable learner assessment, and to clinical translation of SBME outcomes.…”

We hypothesized that a harvested real umbilical cord mounted on a low-technology newborn doll for SBME results in improved learning and greater validity compared with an identical SBME design using a synthetic umbilical cord simulator.…”

Background This study of umbilical catheterization deliberate practice training compared skill and knowledge outcomes of umbilical catheterization using a tissue‐hybrid simulator (REAL) versus a synthetic simulated umbilical cord task trainer (ART). Methods This was a prospective randomized control study. Pediatric residents were randomized to REAL or ART umbilical catheterization deliberate practice training. Pre–post‐training changes in skill performance and knowledge scores for REAL and ART groups were compared. Fidelity of REAL and ART were compared by neonatologists. Results Twenty‐seven pediatric residents completed training. Post‐training mean skill scores were improved compared to pre‐test scores (REAL, P < 0.001; ART, P < 0.0001). Post‐training skill, knowledge, and self‐efficacy scores were not different between the REAL and ART groups. Fidelity of REAL was higher than ART for neonatologists (P < 0.01). Conclusions The face validity of REAL was superior to ART, but resident umbilical cord deliberate practice training demonstrated no difference in skill, knowledge, and self‐efficacy improvements between REAL and ART. Further studies on real patients are needed to evaluate the impact of using real or simulated umbilical cords for umbilical venous catheter/umbilical arterial catheter training.

“…Emergency UVC training can use one of the two types of umbilical cord models: simulated umbilical cord and real umbilical cord. Prior research has shown that emergency UVC training with real umbilical cords has educational advantages for some learners [ 9 ]. In this Technical Report, we describe how to create a real human umbilical cord simulator model for emergency UVC placement training.…”

Emergency umbilical venous catheter placement is a critical procedure during newborn resuscitation. Providing training in this high-acuity and low-frequency procedure is important to optimize the skills of newborn resuscitation teams. Available simulators use simulated umbilical cords which are lower in fidelity than real human umbilical cords and may not provide optimal training. This technical report describes the creation and use of a real human umbilical cord simulator model for emergency umbilical venous catheter placement training. This low-cost model provides learners the opportunity to experience placing an emergency umbilical venous catheter in a real umbilical cord, providing a more realistic training model than currently available commercial simulators.
