The Odum Institute survey research group, led by assistant director Teresa Edwards, has been working with Dr. Jessica Zègre-Hemsey to provide guidance, dissemination, and data collection on a statewide survey as part of Dr. Zègre-Hemsey’s study titled “Optimizing Electrocardiographic Methods for the Early Identification of ST-Elevation Myocardial Infarction in Prehospital Cardiac Care,”

“Teresa’s expertise in survey development and dissemination has been invaluable in achieving our 75% response rate to date,” said Dr. Zègre-Hemsey on working with Edwards and the Odum survey group.

Dr. Zègre-Hemsey’s research focuses on strategies to advance care and optimize outcomes for patients with acute coronary syndrome (ACS) and other time-sensitive cardiovascular diseases. Specifically, her work aims to improve the early and accurate diagnosis of these conditions with (1) cardiac monitoring (electrocardiography) and other non-invasive physiological measures, and (2) implementation of evidence-based innovations into systems of care, both in the prehospital and acute care settings. Her goal is to enhance triage, risk stratification, clinical decision-making, and patient access to definitive cardiovascular care.

The survey that Odum has helped to develop and disseminate was sent to all EMS medical directors and administrators across the state to collect data on current EMS practice and protocols for prehospital ECG interpretation. The aim of this survey is to examine prehospital ECG interpretation methods for patients who have been transported by ambulance with chest pain and/or anginal equivalent symptoms in North Carolina. This research is highly interdisciplinary and involves multiple domains including medicine, cardiovascular epidemiology, EMS, and nursing.

Dr. Zègre-Hemsey and her team will use the survey data to describe EMS systems’ prehospital ECG protocol(s) for acquisition and interpretation, organized by county, and document the number of prehospital ECG’s acquired and the type of prehospital ECG interpretation method(s) used by EMS systems annually in NC. They will also be able to contextualize the association of prehospital ECG interpretation method(s) further regarding EMS provider characteristics (i.e. level of training, years of experience), agency characteristics (i.e. private versus public), and geographic setting (i.e. rural, suburban, and urban).
