Data That Drives Change: ESO at EMS World 2025

As a data-driven organization, ESO believes collective insights can spark industry-shifting research. Because of that belief, we’re especially proud to share that the ESO Data Collaborative powered nearly 30% of the work presented at this year’s EMS World.

Held over three days in Austin, Texas, EMS World brings together thought leaders and professionals at every level to exchange research, innovations, and the practices transforming the field. It serves as a hub for conversation, collaboration, and – most importantly – discoveries that move patient care forward.

The ESO Data Collaborative remains one of the largest datasets for public safety and healthcare research in the country. More than 2,700 EMS agencies, fire departments, and hospitals contribute data, creating a powerful resource for researchers. As a result, this collective dataset continues to shape studies that push the boundaries of what’s possible in emergency care.

This year, several projects using ESO Data earned top honors, further highlighting the impact of shared insights across the EMS community.

➜ A Description of Characteristics and Outcomes for Injured Patients Receiving Prehospital Whole Blood Using a Statewide Linked EMS and Trauma Registry
by Jessica Rosner, DrPH, Daisy Banta, Remle Crowe, PhD, Edward Preusser, and Antonio Fernandez received recognition for being one of the Top 2 Trauma Posters.  

• Study Background:
  Traumatic injuries cause 4.4 million deaths annually and represent nearly 8% of all fatalities (WHO, 2024). Additionally, 30–40% of trauma deaths result from blood loss, with more than half occurring during prehospital care. Early transfusion significantly improves survival (Levy, 2024; Kauvar, 2006).

  Objective:
  The study linked EMS and trauma patient care records to evaluate demographic, injury, EMS response, and outcome data for Virginia trauma patients who received prehospital whole blood.

  Key Findings:
  Patients who received prehospital whole blood experienced a 69% survival rate. Moreover, 25% of patients had transport times greater than 26 minutes, underscoring the need for timely intervention and thoughtful resource planning.

➜ Prehospital Paralytic Only Intubation; A Descriptive Analysis 
by Elizabeth Blizzard, Sydney Jarvis, and Jeffrey L. Jarvis, MD, MS, EMT-P was recognized for Best Clinical Research Oral Presentation.  

• Study Background:
  Up to 3% of patients may experience awareness during intubation without sedation, a factor associated with psychological trauma.

  Objective:
  The research team set out to determine the prevalence of paralytic-only intubation (POI) and describe the practice across EMS encounters.

  Methods and Findings:
  From 12,713 airway management cases, researchers reviewed 173 intubations and confirmed 112 POI cases – less than 1% of all intubations. The most common drivers included decreased mental status and documentation error. Even so, the study highlights the need for additional research to help clinicians balance risks and improve patient experience.

With a mission to improve community health and safety outcomes through the power of data, ESO is incredibly proud of the hard work and dedication of the industry’s researchers working diligently to make advancements in the field.
