PCRF Research Podcasts

The Prehospital Care Research Forum is dedicated to fostering and improving research in EMS. Below you will find select podcasts discussing current research that affects EMS. These podcasts are meant to review methodology and applicability to prehospital care, promote healthy and respectful discussions, and inspire new research. We encourage you to comment on the podcasts and make suggestions as to how we can improve this feature.

Paramedic Ability to Recognize STEMI on Prehospital ECGs by Alex, Pete, Keith

In this study, paramedics were given a survey of ECG print outs and asked to identify an ST segment elevation myocardial infarction (STEMI) out of 10 rhythm strips. Paramedics were able to correctly identify the inferior STEMI 96% of the time. They identified the lateral STEMI (51%) and the anterior STEMI (78%) at demonstrably lower frequencies. In this podcast, the speakers recognize the potential shortcomings of the study design: the ECG print outs utilized were markedly difficult to interpret, were borderline in terms of STEMI mimics, and were prone to under-evaluation due to lack of patient context. The conclusion drawn from this study states that “given the paramedics' low sensitivity and specificity, we cannot rely solely on their ECG interpretation to activate the cardiac catheterization laboratory,” but the speakers criticize this assertion given the study design and potential motivation.

"Pediatric Anaphylaxis Management in the Prehospital Setting" by Alexander, Peter, Keith

A recent retrospective study analyzing the management of pediatric anaphylaxis was performed by comparing discharge diagnoses with prehospital patient care reports. The study concluded that in the 218 cases of anaphylaxis analyzed, only 36% of patients received an intramuscular injection of epinephrine. Much of this discrepancy was likely due to the fact that these patients received epinephrine before EMS arrival. The protocols for the EMS agency responding to these calls were also such that epinephrine was the last line in interventions for the treatment of anaphylaxis. This study does, however, demonstrate the greater need for the differentiation of anaphylaxis from other respiratory ailments by EMS providers.

Prehospital Point-of-Care Testing for Troponin: Are the Results Reliable? by David, Joshua, Keith, Aaron

A study conducted by J. Venturini, C. Stake, and M. Cichon demonstrated the viability of using prehospital troponin levels as a diagnostic tool for patient care and transport destination.  An i-STAT machine was used to assess patient troponin levels enroute and again at the ED to determine the correlation between the two results.  The study showed high correlation between the two sample tests, indicating the potential for this device to be used in the field.

Psychometric Testing of the Jefferson Scale of Empathy with Paramedic Students by David, Alexander, Keith, Chris

This study was performed to analyze the Jefferson Scale of Empathy Health Profession and its measurement of empathy in health care providers. A modified Jefferson Scale was given to paramedic students in a large Australian university to determine their level of empathy. The study showed a positive correlation between the students’ scores in “compassionate care” and “perspective taking,” confirming that the Jefferson Scale is a valid and reliable measure for empathy in paramedic students.

Neurologically Favorable Survival After In-Hospital Cardiac Arrest by David, Alexander, Keith, Peter

A recent article in the Journal of the American Medical Association entitled "Vasopressin, steroids, and epinephrine and neurologically favorable survival after in-hospital cardiac arrest: a randomized clinical trial" describes a double blind, randomized study performed in Greece regarding cardiac arrest survival to hospital discharge.
