ObjectivePoint-of-care ultrasound (POCUS) is now ubiquitous in emergency medicine. Increased accessibility does not, however, ensure expertise in its use. We present a unique model of an Emergency Medicine Advanced Ultrasound Service (EMAUS). In our model specialist emergency physicians with advanced ultrasound (US) qualifications (emergency sonologists), provide images and reports for the entire department. The service is considered an extension of the traditional radiology model. It is consultative, diagnostic and procedural, and includes full US examinations as well as POCUS examinations.MethodsA 4-month prospective descriptive observational study was conducted at a tertiary hospital during which data was recorded about emergency medicine US use and its outcomes.ResultsA total of 1336 US scans were recorded. Emergency sonologists conducted the majority of examinations, 69.8%. Half the consultative USs demonstrated positive findings. Follow-up computed tomography (CT) was recommended in 8.8% of consultative US studies and 12.4% of POCUS studies. Concerning incidental findings requiring further investigation (usually CT/magnetic resonance imaging) were infrequent at 1.6%.ConclusionGlobally POCUS has proliferated with varying expertise and data to support its use. The EMAUS provides a trusted and accountable service with the advantages of simultaneously integrating consultative US into the clinical context by an emergency physician. A diverse range of indications, scan types and pathology was recorded over the period demonstrating the utility of combining the roles of senior clinician, sonographer and radiologist and the benefits of advanced training and credentialing.© 2020 Australasian College for Emergency Medicine.
