National Registry’s EMS Practice Analysis Accepted For Publication

January 19, 2021

COLUMBUS, OH – The National Registry announced that the 2019 EMS ALS Practice Analysis was accepted for publication by the National Association of EMS Physicians’ journal, Prehospital Emergency Care. This is an exciting step in providing the EMS community a clear vision of current care provided in the prehospital setting, including the tasks performed by EMS practitioners. The National Registry conducted the practice analysis for the Advanced Life Support levels (Paramedic and AEMT) in 2019 using data from multiple sources, including the National Emergency Medical Services Information System (NEMSIS), surveys from active EMS providers and recommendations from EMS subject matter experts. The BLS levels (EMR and EMT) Practice Analysis will be conducted in 2022.

“Through the practice analysis we wanted to clearly define the current daily practice of Paramedics and AEMTs so that it can inform examinations on a national level,” said Dr. Ashish R. Panchal, Research and Fellowship Director for the National Registry of EMTs and an EMS Physician at The Ohio State University. “This is why we used the largest available datasets, like NEMSIS, leveraging its over 25 million EMS activations across the United States. Globally, as we understand the changing dynamics of care, we can better focus on improving prehospital care.”

The 2019 EMS Practice Analysis will help inform many aspects of the EMS system, including the National EMS Educational Standards and National Registry certification exams.

Key Facts in the 2019 EMS Practice Analysis

  • More than 3,500 EMS professionals were involved in the 2019 Practice Analysis, including staff, panel members and survey respondents. Data from 10,000 EMS agencies was included in the Practice Analysis.

  • The most common pediatric impressions were traumatic injury, behavioral/psychiatric disorder, respiratory distress/arrest, seizure, and abdominal pain/problems.
  • The highest risk of harm for adults were identified as airway obstruction, respiratory distress/arrest, cardiac arrest, hypovolemia/shock, allergic reaction, or stroke/CVA
  • In comparison, pediatric patients presenting with airway obstruction, respiratory distress/arrest, cardiac arrest, hypovolemia/shock, allergic reaction, stroke/CVA, and inhalation injury had the highest potential for harm.
  • A total of 532 tasks (a unique activity performed by an EMS professional) and 2,290 associated knowledge, skills and abilities (KSAs) required to accomplish the task were defined for the Paramedic level.
