"Debriefing-on-Demand": A Pilot Assessment of Using a "Pause Button" in Medical Simulation.
Simulation is an effective tool in medical education with debriefing as the cardinal educational component. Alternate debriefing strategies might further enhance the educational value of simulation. Here, we pilot a novel strategy that allows trainees to initiate debriefing at any point during the scenario, when they consider it necessary. ⋯ Debriefing-on-demand was easily integrated into all scenarios and well received by these trainees new to simulation. Larger trials that use validated tools are needed to determine the absolute impact of debriefing-on-demand on stress levels and the overall learning value of simulation for trainees at different levels of training.

Learning Neonatal Intubation Using the Videolaryngoscope: A Randomized Trial on Mannequins.
The use of the videolaryngoscope (VL) facilitates intubation in adults and children, but experience in neonates is scarce. The objective of this study was to compare the VL with the classic laryngoscope (CL) in acquiring the skill of neonatal endotracheal intubation (ETI) and evaluate transferability of skill from VL to CL. We hypothesize that, on a neonatal mannequin, the VL will be superior to the CL with regard to success rate and that the skill will be transferred from VL to CL. ⋯ Success rate of ETI on mannequins was improved, and esophageal intubations decreased while learning ETI using the VL compared with the CL. Once ETI is learned on mannequins using the VL, this skill is transferrable to the CL.

High-fidelity simulation-based training is often avoided for early-stage students because of the assumption that while practicing newly learned skills, they are ill suited to processing multiple demands, which can lead to "cognitive overload" and poorer learning outcomes. We tested this assumption using a mixed-methods experimental design manipulating psychological immersion. ⋯ High-environmental fidelity simulation engendered immersion and a sense of urgency in students, whereas LF(en)S created assessment anxiety and slower performance. We conclude that once early-stage students have learned the basics of a clinical skill, throwing them in the "deep end" of high-fidelity simulation creates significant additional cognitive burden but this has considerable educational merit.

Simulation Improves Procedural Protocol Adherence During Central Venous Catheter Placement: A Randomized Controlled Trial.
Simulation training may improve proficiency at and reduce complications from central venous catheter (CVC) placement, but the scope of simulation's effect remains unclear. This randomized controlled trial evaluated the effects of a pragmatic CVC simulation program on procedural protocol adherence, technical skill, and patient outcomes. ⋯ Simulation training added to standard training improved protocol adherence during CVC insertion by novice practitioners. This study may have been too small to detect meaningful differences in venous cannulation proficiency and other clinical outcomes, highlighting the difficulty of patient-centered simulation research in settings where poor outcomes are rare. For high-performing systems, where protocol deviations may provide an important proxy for rare procedural complications, simulation may improve CVC insertion quality and safety.

Comparison of Chest Compressions Metrics Measured Using the Laerdal Skill Reporter and Q-CPR: A Simulation Study.
There has been an increased emphasis on the quality of chest compressions as a part of the cardiopulmonary resuscitation (CPR) bundle of care for recent times. During CPR training, chest compression quality parameters can be measured directly from sensors within a manikin or from external devices placed on the manikin chest that use accelerometer-based technology. The aim of this study was to compare external chest compression data from the manikin-based Laerdal Skill Reporter (LSR) and the accelerometer-based Q-CPR technology, incorporated into the Philips MRx defibrillator, during CPR on a single Resusci Anne Simulator manikin. ⋯ There was no significant difference in most chest compression quality metrics measured between the LSR and the Phillips Q-CPR devices when measured on a manikin. However, there were significant differences in the measurement of duty cycle and also the depth of compressions between the 2 devices with the Phillips Q-CPR device measuring lower depth of compression and duty cycle compared with the LSR device.
