Emergency Ultrasound

The Ultrasound (US) Division in the Department of Emergency Medicine has led point-of-care ultrasound in Atrium Health since 1996, with system-wide leadership in adopting, incorporating into practice, credentialing, continuing medical education, graduate medical education, undergraduate medical education, nursing, military, resuscitation and diagnostic care pathways, and other ultrasound programs. Our physicians have become national and international leaders on the topic of clinical, point-of-care emergency ultrasound and utilize ultrasound in care daily.

Emergency point-of-care ultrasound is an integral subspecialty at Atrium Health Carolinas Medical Center (CMC). Founded by Dr. Tayal in 1996, emergency POC ultrasound has been used for resuscitative, diagnostic and procedural applications. With over 15,000 ultrasounds done per year, ultrasound is part of the daily care in the CMC emergency department (ED). In addition, our ultrasound division has a long history of performing ground-breaking and meaningful research on various topics in Emergency Ultrasound. The Department of Emergency Medicine firmly supports ultrasound as one of the bedside tools the emergency physician should master to properly evaluate patients during emergency care. We utilize all the 2016 ACEP US applications, with several evolving uses of TEE, volume imaging and US guided nerve blocks. Within the Department of Emergency Medicine, the Division of Emergency Ultrasound has expanded with the addition of ultrasound fellowship-trained faculty and the maturation of the emergency ultrasound fellowship. The CMC ED was one of the first EDs in the United States accredited by the ACEP Clinical Ultrasound Accreditation Program (CUAP). The US Division leads POC education, credentialing, research and practice across the health system.

Operations and Clinical Care

Director of Operations – Vitaliy Belyshev, MD
The department has over 11 ultrasound machines that are in continual use. Each machine is capable of extensive imaging techniques such as doppler with a wide array of probe types. All are networked for automated wireless image/clip transmission and allow for offsite viewing using QPATH cloud-based storage. The volume of emergency ultrasounds performed has grown each year to an annual ultrasound procedure census of 15,000 per year. The attending physicians are credentialed, and a quality assurance program audits every ultrasound performed in the ED. Ultrasound is used extensively for resuscitation (both non-traumatic and traumatic), pregnancy, abdominal evaluation, cardiovascular evaluation, soft-tissue, musculoskeletal, ocular, biliary, urinary tract, DVT, bowel and for procedural guidance in both adults and our pediatric application. Recent additions to our armamentarium including advanced nerve blocks including Fascia Iliaca, ESP and brachial plexus blocks. Further advanced imaging modalities such as volume flow, spectral tracking and TEE are being incorporated. Quality assurance is built into daily emergency medicine care and the US division’s workflow.

Educational Programs

We teach across the medical educational spectrum including US fellowship, EM residents, medical students, community and faculty physician, advanced practice providers, military medics, nurses and rotators from other departments.

Fellowship Training

Director – Denise Fraga, MD
The US fellowship was initiated in 2005 by Dr. Tayal. In 2008, with Dr. Weekes as fellowship director. In 2019, Denise Fraga, MD, became the US Fellowship Director. Our US Division offers a one-year postgraduate Ultrasound fellowship that meets the new ABEM EUFAC Emergency Medicine Clinical Ultrasonography Accreditation criteria (pending the accreditation initiation). The ultrasound fellow is expected to be involved in clinical ultrasound research, obtain extensive experience with ultrasound program development and maintenance with special attention to quality assurance and develop strong teaching skills. The fellow will develop an extensive knowledge base through group didactic sessions, bedside teaching of learners and supervised scan sessions with 'ultrasound' faculty. Our fellowship features advanced ultrasound applications, teaching ultrasound at all levels, ultrasound research and ultrasound experience in other clinical and imaging department such as Cardiology and Anesthesia.  In addition, the US fellow is active junior faculty attending physician with shifts in both the Adult and Pediatric Emergency Care areas. Clinically, the fellow exclusively works at the CMC Main campus as an academic attending. The CMC Emergency Department has over 100,000 annual visits and serves as a referral center for trauma, cardiac arrest, stroke, MI, medical resuscitation and pediatric emergencies. An active simulation center offers ultrasound simulators as well.

Residency Training

Director of Emergency Medicine (EM) Residency Training - Vivek Tayal, MD
Director of EM PGY3 Elective – Vitaliy Belyshev, MD
CMC EM Ultrasound Residency training started in 1997 and has been a primary mission of the US Division. Beginning with the orientation US intern course, US is incorporated into residency training from day one. The ultr

asound training throughout residency includes a dedicated month of US in the PGY1 year with online didactics and hands-on scanning shifts with ultrasound faculty. PGY years 2 and 3 feature integrated US goals and a PGY-3 US elective. EM residents are expected to meet and complete quality EM US examinations that meet the ACEP Ultrasound Guidelines and pass an end of residency US test. As EM residents use ultrasound during their clinical evaluation of patients in the ED, residents naturally become teachers and leaders in the department and other rotations as they assume more responsibility during the residency. In addition, many residents also participate in the international opportunities in Tanzania and Guatemala to teach and use ultrasound in international settings.

Director, Medical School Education – Margaret Lewis, MD
Led by Dr. Margaret Lewis and in collaboration with the University of North Carolina at Charlotte, our medical education program includes a US curriculum as part of the Continuous Longitudinal Integrated Curriculum for the MS3 and MS4 year students. Through didactics and hands-on scan labs, the curriculum exposes students to the basics of bedside point of care ultrasound. Our students have represented the University of North Carolina at SonoSlam each year and continuously rank th

e ultrasound program as one of the top reasons they choose the Charlotte Campus. As Atrium Health associates with Wake Forest University School of Medicine, we are excited to continue to integrate ultrasound education for students choosing the Charlotte campus for their 3^rd and 4^th year.

Pediatric Emergency Ultrasound

Director, Pediatric Emergency Ultrasound – Lindsey Chaudoin, MD
Pediatric emergency ultrasound is fully integrated in the emergency ultrasound program. Residents and fellows have pediatric specific ultrasound didactics and hands-on training by fellowship-trained ultrasound faculty. Ultrasound is used in pediatric resuscitation and diagnosis routinely, with the same credentialing process for faculty as with adult patients. With a focus on best practices, throughput and education, ultrasound research is ongoing in our department to optimize care for our pediatric population.

Ultrasound Research

Director, Emergency Medicine Research – Anthony Weekes, MD
Our division’s research in ultrasound has covered the spectrum of point of care clinical application and procedures. Our division faculty are actively involved in clinical and educational ultrasound research. Faculty have collaborated on regional research projects including the REASON trial (cardiac ultrasound in cardiac arrest). Our former ultrasound fellowship director, Anthony Weekes, MD MSc, is now the director of Emergency Medicine Research Division.
