Numerous studies reported on the frequency of, and factors associated with inappropriate or unnecessary emergency department (ED) visits using clinician judgment as the gold standard of appropriateness. This study evaluated the reliability of clinician judgment for assessing appropriateness of pediatric ED visit. ⋯ Although an important contributor to pediatric ED overcrowding, unnecessary or inappropriate visits are difficult to identify. We demonstrated poor reliability of clinician judgment to determine appropriateness of ED return visits, likely due to variability in clinical decision-making and risk-tolerance, social and systems factors impacting access and use of health care. We recommend that future studies evaluating the appropriateness of ED use standardized, objective criteria rather than clinician judgment alone.

Military Forward Aeromedical Evacuation and civilian Helicopter Emergency Medical Services are widely used to conduct Primary Aeromedical Retrieval. Crew composition in Primary Aeromedical Retrieval missions varies considerably. The ideal composition is unknown. Thus, we conducted a descriptive systematic review on mortality and other outcomes for different Primary Aeromedical Retrieval crew compositions. ⋯ Overall, findings were divergent but showed a trend to decreased mortality in patients treated by advanced providers with interventions beyond the basic paramedic level. This trend was most significant in patients with severe but survivable injuries. These results should be cautiously interpreted because most studies were observational, had small sample sizes, and had a high potential for confounding factors.

Observational Study
Quality of abdominal ultrasound image acquisition by novice practitioners following a minimal training session on healthy volunteers.
Point of care ultrasound (POCUS) is an essential tool for physicians to guide treatment decisions in both hospital and prehospital settings. Despite the potential patient care and system utilization benefits of prehospital ultrasound, the financial burden of a "hands-on" training program for large numbers of paramedics remains a barrier to implementation. In this study, we conducted a prospective, observational, double-blinded study comparing paramedics to emergency physicians in their ability to generate usable abdominal ultrasound images after a 1-hour didactic training session. ⋯ Paramedics were not able to produce images of interpretable quality at the same frequency when compared with emergency medicine physicians. However, a 61.4% usable image rate for paramedics following a short 1-hour didactic training session is promising for future studies, which could incorporate a short hands-on tutorial while remaining cost-effective.
