Kaplan SL, Chen AE, Rempell RG, et al. - This study was intended to evaluate variations in Rad US ordered by emergency medicine (EM) as point-of-care ultrasound (POCUS) began and grew at their pediatric hospital. Researchers performed a retrospective study including EM POCUS and EM-ordered Rad US volumes between 2011 and 2017, during three 2-year intervals: before POCUS, early POCUS, and expanded POCUS. They analyzed volume differences applying the Mann-Whitney U test (significance threshold, and applied process control charts to distinguish nonrandom variations. This research enrolled 49,908 Rad US and 2,772 POCUS examinations during 647,890 emergency department visits. It was noted that for skin and soft tissue infections, rad US overall and specifically elevated or remained stable during the introduction and growth of EM POCUS. Rather than reducing Rad US, EM POCUS had a complementary role.
