Research in Prehospital Medicine / EMS
 
 
Faculty at the Department of Emergency Medicine have the opportunity to collaborate with leading researchers in the fields of emergency medicine, trauma, prehospital care, and public health. The National Student Center for Trauma and Emergency Medical Systems (NSC) is housed on the University of Maryland, Baltimore's Campus. Dr. Jon Mark Hirshon, Professor of Emergency Medicine, founded the Maryland Emergency Medical Services Systems Research Interest Group (MEMSS-RIG). The group brings together researches from institutions such as Johns Hopkins School of Medicine, the Univerity of Maryland School of Medicine, and the Maryland Institute for Emergency Medical Services Systems (MIEMSS). MEMSS-RIG faculty are committed to advancing the practice of prehospital medicine through ongoing research. Members have contributed to  a number of peer-reviewed articles and have worked on the development of evidence based guidelines for EMS triage, pain management, and aeromedica transport. Examples of ongoing research projects include:

1. A cost effetive analysis of fire-department based community CPR programs
2. The impact of a local freestanding ED upon surronding emergency medical services jurisdiction
3. Review of aeromedical transport and utilization within Maryland
4. Cochrane-style review of post-arrest percutaneous coronary intervention
 
The National Study Center for Trauma and Emergency Medical Systems (NSC) is housed on the University's campus and represents another resource for research-related contributions to EMS.

Ongoing Research and Quality Improvement Projects
Updated: January 2016

 

1. Cardiac Arrest Research: Pre and Post Survey of Citizens Attending Bystander CPR classes
Lead investigators: Bouland AJ, Halliday M, Lawner B
Research Question(s): Identification of barriers linked to performing CPR
Status: data analysis 

2. Cardiac Arrest Research: Survey of the General Public about Performance of Bystander CPR
Lead investigators: Bouland AJ, Fratta, K, George N
Research Question(s): General survery related to quantifying barriers to initial performance of CPR
Status: ongoing data collection 

3. EMS Operations: Baltimore City Fire Department's Medical Duty Officer Program and its Effect Upon Urban EMS System Metrics
Lead investigators: Halliday M, Ramos D, Lawner B
Research Question(s): Does the implementation of a senior paramedic/EMS officer within the unified dispatch center result in decreased ambulance offload times
Status: manuscript in progress

4. ED/EMS Interface: The Effect of Real Time Feedback on Handoff Between EMS and ED During CPR
Lead investigators: Bussey I, Brown R, Smith L, Lawner B
Research Question(s): Does a standardized hand off process or protocolized approach to the transfer of care lead to decreased interruptions in compressions and ongoing cardiac arrest care
Status: refinement of research question, IRB process

5. Emergency Public Health: Suitability of screening criteria for EMS transfer to a sobering center
Lead investigators: Fraga DN, Lawner B
Research Question(s): Would ED patients with substance use disorders such as alcohol intoxication be eligible for direct transfer to a detox/sobering center from the field? 
Status: refinement of research question, IRB process

6. Mass Gathering Medicine: Review of the literature related to electronic dance music (EDM) festivals
Lead investigators: Fitzgibbon K 
Resarch question(s): Do currently available models accurately predict the need for medical resources at EDM events? What injury patterns distinguish EDM from other types of mass gathering events?
