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.

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.
