Here's what new ED ultrasound guidelines say.

New ED ultrasound guidelines from the American College of Emergency Physicians give recommendations for training, scope of practice, quality assurance, and certification. The guidelines recommend that 150 ultrasound examinations be completed, but if an individual isn't proficient, more examinations must be required. All ultrasound studies during the credentialing period should be compared to gold standard studies, such as computed tomography scan or operative reports. You must be clear about the limitations of ED ultrasound examinations when consulting with specialists.
