UMSOM team to provide trauma datasets to help predict the need for lifesaving interventions in real time

Peter Hu, PhDIn an effort to better optimize the triage of patients during mass casualty events, University of Maryland School of Medicine (UMSOM) researchers are receiving up to $7.3 million in funding from the Defense Advanced Research Project Agency (DARPA) for vital new research. The funding will be used to support a study that will collect data over the next 3.5 years on trauma patients with the aim of identifying and implementing lifesaving advancements in medical triage for large-scale mass casualty incidents.

The importance of early interventions in trauma is described as the concept of the ‘golden hour’, which means the first hour of trauma care is very important,” said study Principal Investigator Peter Hu, PhD, Professor of Anesthesiology at UMSOM and Chief Technologist at the R Adams Cowley Shock Trauma Center at the University of Maryland Medical Center (UMMC). When disasters happen, if we can use machine learning to rapidly predict the need for lifesaving interventions, we can be more effective in triage – especially in situations where medical personnel are limited.”

DARPA’s Research Infrastructure for Trauma with Medical Observations (RITMO) effort, which is funding the study, aims to create a single database of de-identified trauma patient data derived from the early post-injury period. The RITMO program is the foundational data component of the DARPA Triage Challenge, a 3.5-year challenge designed to drive the development of physiological ‘signatures’ of injury that will help medical responders quickly assess patient vital signs, make triage decisions and render aid to the critically injured in military and civilian mass casualty incidents. Mass casualty incidents involve multiple injured patients and can include large-scale traffic accidents, natural disasters like hurricanes or wildfires, or violent attacks like mass shootings.  

Samuel Galvagno, DO, PhD“As a member of our armed forces, I am proud to see our faculty collaborate on the development of this cutting-edge technology in trauma triage,” said Col.  Samuel Galvagno, DO, PhD, MS, MBA, FCCM Professor and Interim Chair of the Department of Anesthesiology at UMSOM, Interim Chief of Anesthesiology at UMMC and a General Officer in the United States Air Force Reserve. “This work extends beyond military combat and will universally transform how we approach trauma care.”

The UMSOM team will collect de-identified data on trauma patients ages 18 to 65 who are admitted to the R Adams Cowley Shock Trauma Center over the next three years. Data collected will include continuous patient vital signs and lifesaving medical intervention data through each stage of trauma triage including field care, helicopter transport, trauma center reception, and resuscitation and stabilization. The UMSOM team will also contribute additional indicators of patient status such as brain and tissue oxygen readings to help identify potential neurological injuries.

Thomas M. Scalea, MD“With minute-by-minute patient data, we can have a clearer picture of where a patient is deteriorating and prepare our trauma teams with critical answers such as how much blood may be needed upon arrival,” said Thomas Scalea, MD, The Honorable Francis X. Kelly Distinguished Professor of Trauma Surgery at UMSOM, Director of the Program in Trauma, and Physician-in-Chief of the Shock Trauma Center. “Being able to obtain real-time insights before patients reach the trauma center is pivotal in the advancement of the triage process.”

Findings from this new study will also be used in a separate RITMO initiative called the DARPA Triage Challenge data competition. Teams in the data competition are challenged to develop algorithms that will detect the signatures of injury through non-invasive sensors. This will provide insights that will enable accuracy in triage decision-making such as prioritization for medical evacuation.

Sarah Murthi, MDAs part of the DARPA Triage Challenge, a University of Maryland College Park robotics team is working on building drones with stand-off sensors that will utilize the algorithms to drive the aerial assessment of vitals and injuries in real-time. Sarah Murthi, MD, Professor of Surgery at UMSOM and a critical care surgeon at the Shock Trauma Center, is part of this team and will contribute her expertise on medical sensing and triage procedures.

Mark T. Gladwin, MD“The number of U.S. shootings with multiple victims has nearly doubled over the past five years to more than 600 shootings per year, which underscores the dire need to advance new triage technologies,” said Mark T. Gladwin, MD, the John Z. and Akiko K. Bowers Distinguished Professor and Dean, UMSOM, and Vice President for Medical Affairs, University of Maryland, Baltimore. “Combining high-resolution physiological data with machine-learning tools will ultimately yield a new form of precision medicine in critical care to better assess a trauma patients’ immediate needs with the ultimate aim of saving lives.”

Over the past 10 years, Dr. Hu and his colleagues have received $35 million in grant funding to contribute data and aid the development of lifesaving interventions in trauma. He is also working on other research to predict the early need for blood transfusions in mass casualty incidents.
