Research & Scholarship
We are translating experience into evidence-based knowledge for the advancement of critical patient care.
Large patient volumes and a phenomenal array of state-of-the-art resources allow innovation to thrive in the Emergency Department at UT Southwestern. Our passion and curiosity perpetually raise the bar and set new standards in care across the full spectrum of subspecialties within our field.
Cardiac Arrest and Resuscitation
- Erik Kulstad leads as site principal investigator for the AWARE-II study investigating quality of brain resuscitation, cognition, and functional recovery in cardiac arrest. He also has significant expertise in temperature management associated with electrophysiology/critical care and medical device development.
- Early in our history, UTSW Emergency Medicine has led critical research in cardiac arrest and resuscitation medicine. This continues to be a main area of focus of active publications and grants. This team is led by Dr. Ahamed Idris, who also serves as the Department’s research director.
“In the last two decades, measurement of the quality of CPR has led to improvements in critical aspects of chest compression (fraction, rate, and depth) that are associated with improved survival. For the first time we have developed machine-learning methods to measure quality of ventilation during CPR, which we think will lead to additional improvements in survival. We are also developing methods to automate cardiac arrest registries that will contribute fundamental knowledge to resuscitation science.”

Dr. Deborah Diercks and Dr. Mark Courtney have a long track record in conducting federal- and industry-sponsored research trials investigating cardiac ischemia, congestive heart failure, and venous thromboembolism. They are leading national experts in disease detection, evaluation of diagnostic testing, risk stratification, and treatment trials.
“Patients come to the ED to be reassured or to have a critical disease discovered and treated appropriately. Efforts to discover how we best implement the right test for the right patients, at the right time, in a manner that optimizes accuracy, safety, and efficiency is key to much of what we do 24/7.”

Emergency Disaster and Global Health
“Over the next one to three years, we will continue to develop international multidisciplinary collaborations to advance the science of disaster medicine and global health. Our collaborative grant with Rabin Medical Center is addressing what the evidence is supporting medical and health system preparedness for mass casualties from limited nuclear and radiologic incidents.”

Emergency Medical Services (EMS)
The Emergency Medical Services Division of the Department of Emergency Medicine is actively involved in studying critical areas of science related to improving the care of the acutely ill and injured in the prehospital setting.
One recent area of interest has involved linking EMS medical records to hospital records in patients with out-of-hospital cardiac arrest, a project conducted in collaboration with the American Heart Association.
Current efforts also include the minimum requirement for training in dispatch centers to provide instructions for cardiac arrest management, and a focus on electrocardiographic changes that are predictive for sudden death.
Opioid vs. non-opioid pain medication
Another recent effort brought focus on the use of opioid versus non-opioid pain medication in the field, including obstacles to the use of non-opioid treatment.
In times of need, the ED is the destination for persons at risk from life-threatening pathogens. Joby Thoppil, M.D. and Sam McDonald, M.D. are working together to bring efficiency to the evaluation of sepsis and to better understand the unique patient subtypes and pathogen/metabolic/host factors most predictive of outcome.
- Deborah Diercks, M.D. has brought her expertise in disease detection and lab testing to the domain of COVID and leads multiple studies analyzing the disease prevalence rate, development of immunity and overall scope of the problem among high risk populations out of the ED. This has included over $500,000 to test over 1,000 people for COVID who are followed over time. These projects are ongoing in EMS, police frontline providers, and most recently, childcare workers.
- Mark Courtney, M.D. has led efforts in support of the RECOVER multicenter ED-based COVID registry that seeks to develop prediction rules for who is likely to have a positive test as well as who is likely to have an adverse outcome of death, ICU care, or mechanical ventilation.
- Ahamed Idris, M.D. has led our efforts as a site for the COVERED study analyzing exposure, transmission and impact of COVID among ED personnel. He is also leading the INSPIRE study funded by the Centers for Disease Control and Prevention.
- Sam McDonald, M.D. is participating in a leadership role within our institution on the PRESTO study using signals from the EMR, blood and other sources to predict severity of illness, funded by Verily.
“With the abundance of resources at UTSW and large patient volumes in our emergency departments, we are an ideal location to study emerging pathogens. We aim to translate experience into evidence-based knowledge to best serve our patients.”
Informatics and Health Services Research
We are growing expertise in our capacity to access, analyze, and aggregate large quantities of data from the electronic medical record to systematically understand the complex processes of acute emergent care and provide real time intelligence to support and direct the management of our patients. We can further our scope by coupling with other health systems such as Texas Health Resources in order to understand what happens to our patients when they leave not just our ED but our health system.
Dr. Sam McDonald has led efforts to utilize the EHR and our patients’ data to implement knowledge management systems that enable our clinicians to provide the highest quality of care for patients. His work has helped automate serial testing with a novel high-sensitivity troponin assay used when evaluating patients for possible cardiac ischemia, a test UTSW and Parkland were among the first EDs in the United States to implement. Additionally, he has utilized the EHR to provide automated decision support to streamline sepsis care pathways and now supplement COVID testing and risk stratification.
"With the increasing complexity and volume of patients attending the ED, the cost of decisions made with inadequate information becomes detrimental. With the advancement of the EHR, realizing its capacity for not only knowledge management and care delivery but also knowledge generation is the future of medicine and a goal of not only this department but also UT Southwestern."
