Methods and Implementation of the 2019 EMS Practice Analysis

Background: The EMS Practice Analysis provides a vision of current prehospital care by defining the work performed by EMS professionals. In this manuscript, we present the National Advanced Life Support (ALS) EMS Practice Analysis for the advanced EMT (AEMT) and paramedic levels of certification. The goal of the 2019 EMS Practice Analysis is to define the work performed by EMS professionals and present a new template for future practice analyses. Methods: The project was executed in three phases. Phase 1 defined the types/frequency of EMS clinical presentations using the 2016 National Emergency Medical Services Information System (NEMSIS) dataset. Phase 2 defined the criticality or potential for harm of these clinical presentations through a survey of a random sample of nationally certified EMS professionals and medical directors. Phase 3 defined the tasks and the associated knowledge, skills, and abilities (KSA) that encompass EMS care through focus groups of subject matter experts. Results: In Phase 1, the most common EMS adult impressions were traumatic injury, abdominal pain/problems, respiratory distress/arrest, behavioral/psychiatric disorder, and syncope/fainting. The most common pediatric impressions were traumatic injury, behavioral/psychiatric disorder, respiratory distress/arrest, seizure, and abdominal pain/problems. Criticality was defined in Phase 2 with the highest risk of harm for adults being 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. Finally, in Phase 3, task statements were generated for both paramedic and AEMT certification levels. A total of 425 tasks and 1,734 KSAs were defined for the paramedic level and 405 tasks and 1,636 KSAs were defined for the AEMT level. Conclusion: The 2019 ALS Practice Analysis describes prehospital practice at the AEMT and paramedic levels. This approach allows for a detailed and robust evaluation of EMS care while focusing on each task conducted at each level of certification in EMS. The data can be leveraged to inform the scope of practice, educational standards, and assist in validating the ALS levels of the certification examination.
