Data and Research
Research Grounded in Real-World Data
Delivering benchmarks and insights for the entire response ecosystem.
Data and Research
The ESO Data Collaborative transforms anonymized records from thousands of EMS, fire, and hospital agencies to generate national-level insights. This creates a solid foundation for research and year-over-year benchmarking, so agencies can make evidence-based decisions that improve patient outcomes at scale.

Powerful insights from millions of encounters help agencies improve protocols and strengthen outcomes across the continuum of care
Data Collaborative
The ESO Data Collaborative aggregates anonymized records from thousands of agencies to create a rich data foundation for research and year-over-year benchmarking, so agencies can make evidence-based decisions that improve outcomes at scale.
Research Dataset
The ESO Data Collaborative is backed by the industry’s largest research-grade dataset comprising over 500 million records. Access to this dataset is provided following a research proposal process reviewed by the Research Leader Group.*
Publications and Presentations
The ESO Data Collaborative has powered dozens of research projects, award-winning national conference presentations, and peer-reviewed manuscripts in top medical journals.
Research Leadership Group
The ESO Research Leadership Group is an external, volunteer committee of industry leaders that governs the Data Collaborative’s research. They evaluate data requests to ensure data sufficiency and prevent conflicts of interest. All members are serving as individuals and are not representing any organization: Elizabeth Donnelly, PhD, Jason Moats, PhD, Jeff Jarvis, MD, Joelle Donofrio-Ödmann, MD, Kate Remick, MD, Lawrence Brown, PhD, Jon Kromer, MD, and Rick Verbeek, MD.
*Over 14 million encounters in the dataset. The 2024 ESO Data Collaborative public release research dataset contains 14,831,650 EMS encounters (85% represent 911 responses) from 3,342 agencies. The majority of included EMS responses occurred In the South (50%) US Census region, followed by the Midwest (25%), West (17%) and Northeast (8%). Based on the CMS urban city categorizations, most encounters occurred in urbanized areas (81%).
Approximately, 35% of records with EMS emergency response and patient transport had linked emergency department/ hospital outcome information through the HDE software, with representation from 31% of all agencies participating in the Data Collaborative
