Research Summary

The mission of the division of Emergency Medicine Research is "to research ways to diagnose and treat life-threatening illnesses." As a result, the scope of interests ranges from social science to cell physiology. Clinicians in the department study disease entities or organ systems relevant to acute care. The following is a listing of some of our faculty and their research interests.

Michael Gibbs, MD, FACEP
Professor and Chair, Department of Emergency Medicine
Interim Vice President of Research
Senior Academic Chair – Carolinas HealthCare System Medical Group

Research Interests: Trauma, airway management, medical errors, Emergency Department (ED) operations

Dr. Gibbs completed his emergency medicine residency at the University of Pittsburgh in 1993. He then joined the full-time faculty in the Department of Emergency Medicine at Carolinas Medical Center (CMC), serving as medical director of MedCenter Air and as residency program director for three years. During his initial tenure at CMC, Dr. Gibbs collaborated on a number of clinical trials focusing on the care of ED patients with injury, asthma, seizures and chest pain. He was also involved with several studies assessing the utility of point-of-care testing in the ED. Dr. Gibbs left CMC in 2002 to serve as the chief of emergency medicine at Maine Medical Center. While in Maine, he was closely involved with the creating of a new medical school relationship with Tufts, the founding of a high-fidelity simulation center, and the creation of a large multispecialty physician group. He also led strategic efforts to expand residency programs across the institution. In 2011, Dr. Gibbs returned to CMC as chair of emergency medicine. He serves as co-investigator on several trauma-related research trials. In December of 2013, Dr. Gibbs was named interim vice president of research.

Andrew W. Asimos, MD
Director of Emergency Stroke Care

Research Interests: Stroke, Acute Neuroimaging in Stroke, Seizure, Traumatic Brain Injury, Neurologic Emergencies

Dr. Asimos’ area of research focus is neurological emergencies. He has been an investigator in many stroke, transient ischemic attack (TIA), and traumatic brain injury (TBI) trials, including those evaluating Traxoprodil, Maxipost, and Activated Recombinant Factor VII. He has also led extramurally funded investigator-initiated trials in TIA and acute stroke systems of care.
In 2013, Dr. Asimos launched a multiphase research initiative in collaboration with the Carolinas Epilepsy Network. The ultimate goal of this project is to transform the standard of care for the evaluation of first time seizure patients by performing electroencephalographies (EEGs) in the emergency department (ED) as part of the evaluation of first-time seizures. In 2014, Dr. Asimos and his team are continuing to enroll adult patients in the FiTS (First Time Seizure) study, which is testing how frequently performing an EEG on first time adult seizure patients results in the immediate initiation of antiepileptic medication upon discharge from the ED. Additionally, in 2014, Dr. Asimos and his team are conducting a series of focus groups (the FiTS Focus Group Study) to determine important patient centered outcomes related to first-time seizures and their evaluation. This project is being funded by a seed grant from the Division of Therapeutic Research and Development of Carolinas HealthCare System. Dr. Asimos and his research team will integrate the patient centered outcomes identified in a qualitative research project that will be conducted within the Carolinas Epilepsy Network. Additionally, Dr. Asimos and his research team plan to evaluate the feasibility of utilizing EEG caps in the ED to perform ED EEGs.

Medical Director, Cardiac Arrest Resuscitation Center of Excellence

Research Interests: resuscitation, cardiac arrest, medical innovations

Dr. Pearson received his BS and MS degrees in mechanical engineering from the University of Florida in 1997 and 1998, respectively. He completed medical school at Vanderbilt University in 2002 and completed an emergency medicine residency at the Denver Health Medical Center in 2006. Shortly thereafter, Dr. Pearson joined Carolinas Medical Center (CMC) as clinical faculty and is currently the associate program director of the residency. His interests are resident education, post-cardiac arrest resuscitation, and healthcare for the homeless. In 2007, he established the Code Cool™ post-cardiac arrest resuscitation program at CMC which incorporates therapeutic hypothermia and provides cutting-edge post-cardiac arrest care. He is currently the medical director for Carolinas HealthCare System’s critical care network Code Cool program and is coordinating post-arrest care across 35 hospitals. In 2008, he became the medical director of Shelter Health Services, a non-profit, free clinic for Charlotte's homeless women and children, and currently is the chairman of the Board of Directors of the clinic. The residents and faculty provide the major of volunteer physician hours and continue to fully support clinic operations.

Chad Scarboro, MD
Assistant Professor

Research Interests: pediatric mild traumatic brain injury, radiation safety, and simulation

Dr. Scarboro’s major research interest is mild traumatic brain injury in the pediatric population.  The focus of his research is identifying low-risk patients whose situation may not warrant CT brain imaging.  We are developing an electronic tool based on the PECARN head injury guideline to implement in the electronic medical record which will provide a reference for clinicians who are considering a head CT for mild traumatic brain injury.  We hope to more appropriately target patients who warrant CT brain imaging and provide reassurance when providers are appropriately not ordering CT imaging. As we expand this project, we also hope to identify ways to reduce radiation exposure.

Dr. Scarboro received a bachelor of science in biology from the University of North Carolina at Chapel Hill.  He went to Medical School at Wake Forest University.  Subsequently, he completed his residency in emergency medicine at East Carolina University.  He then came to Carolinas Medical Center to complete a pediatric emergency medicine fellowship, and he is now a member of the faculty.

Anthony J. Weekes MD
Director, Emergency Ultrasound Fellowship

Research Interests: critical care, echocardiography

Dr. Weekes graduated from the Albert Einstein College of Medicine, and the Jacobi Medical Center emergency medicine residency, both in New York City. He has directed emergency ultrasound programs at two hospital centers. He is also a registered diagnostic cardiac sonographer. 

Dr. Weekes has focused on goal-directed echocardiography applications in emergency medicine. Several emergency ultrasound fellows, many emergency medicine residents and some emergency nurses have been strong allies and coauthors in projects to date. He is particularly interested in studying how features of cardiac function are influenced by certain acute disease processes and common emergent interventions.

Dr. Weekes is the South USA regional coordinator of a multicenter study REASON 1 trial: Sonography in Cardiac arrest.

His recent work has evaluated inferior vena cava size and dynamics in response to fluid loading intervention in both critically ill and healthy subjects.  He conducted studies on cardiac output hemodynamic monitoring. His current work involves a rapid cardiac and lung evaluation immediately following central line procedures. His immediate research plans involve point-of-care echocardiography in suspected pulmonary embolism and hemodynamic monitoring in sepsis.
