Learners participating in simulation-based education may experience cognitive overload with potential detrimental effects to learning and performance. Multiple strategies have been proposed to mitigate this detrimental response. However, these strategies have not fully considered the potential benefits of using online platforms, such as accessibility, cost-effectiveness, efficiency, and scalability. Addressing this gap in the literature, preparatory online modules were developed by applying concepts from cognitive load theory and simulation-based education. This study assessed whether using preparatory online modules to deliver weekly pre-briefing content could impact cognitive load and performance. The participants were first-year postgraduate medical trainees participating in a simulation-based resuscitation curriculum. ⋯ Trainees using preparatory online modules during the course component of a simulation-based resuscitation curriculum experienced cognitive load changes consistent with cognitive optimization. This may have contributed to their superior performance in the subsequent OSCE. Future research should explore the long-term impacts of online preparatory training and consider potential barriers to implementation in diverse healthcare environments.

Older trauma patients have a higher mortality yet are more likely to be under-triaged compared to younger patients. Studies have suggested that current trauma team activation criteria are suboptimal for older patients. ⋯ We identified five factors associated with increased 30-day mortality in older trauma patients: GCS < 15, ISS > 15, age ≥ 85 years, anticoagulation, and multimorbidity. These factors should be considered when developing modified trauma team activation criteria for older adults.

SHoC-IVC: Does assessment of the inferior vena cava by point-of-care ultrasound independently predict fluid status in spontaneously breathing patients with undifferentiated hypotension?
Accurately determining the fluid status of a patient during resuscitation in the emergency department (ED) helps guide appropriate fluid administration in the setting of undifferentiated hypotension. Our goal was to determine the diagnostic utility of point-of-care ultrasound (PoCUS) for inferior vena cava (IVC) size and collapsibility in predicting a volume overload fluid status in spontaneously breathing hypotensive ED patients. ⋯ IVC PoCUS is feasible in spontaneously breathing hypotensive adult ED patients, and demonstrates potential value as a predictor of a volume overloaded fluid status in patients with undifferentiated hypotension. IVC size may be the preferred measure.
