Usability Testing Via Simulation: Optimizing the NEAR4PEM Preintubation Checklist With a Human Factors Approach.

Objectives: To inform development of a preintubation checklist for pediatric emergency departments via multicenter usability testing of a prototype checklist.

Methods: This was a prospective, mixed methods study across 7 sites in the National Emergency Airway Registry for Pediatric Emergency Medicine (NEAR4PEM) collaborative. Pediatric emergency medicine attending physicians and senior fellows at each site were first oriented to a checklist prototype, including content previously identified using a modified Delphi approach.

Deposition and Optical Characterization of Sputter Deposited p-Type Delafossite CuGaO Thin Films Using CuO and GaO Targets.

CuGaO thin films were deposited using the RF magnetron sputtering technique using CuO and GaO targets. The films were deposited at room temperature onto a quartz slide. The sputtering power of CuO remained constant at 50 W, while the sputtering power of GaO was systematically varied from 150 W to 200 W.

Quality assurance of late gadolinium enhancement cardiac magnetic resonance images: a deep learning classifier for confidence in the presence or absence of abnormality with potential to prompt real-time image optimization.

Background: Late gadolinium enhancement (LGE) of the myocardium has significant diagnostic and prognostic implications, with even small areas of enhancement being important. Distinguishing between definitely normal and definitely abnormal LGE images is usually straightforward, but diagnostic uncertainty arises when reporters are not sure whether the observed LGE is genuine or not. This uncertainty might be resolved by repetition (to remove artifact) or further acquisition of intersecting images, but this must take place before the scan finishes.

Pediatric Emergency Medicine Didactics and Simulation (PEMDAS): Pediatric Sedation Complications.

Introduction: Ketamine and propofol are commonly used agents for sedation in the pediatric emergency department (PED). While these medications routinely provide safe sedations, there are side effects providers should be able to recognize and manage. Currently, no pediatric sedation simulations exist in the literature.
