Is this 911 call truly an emergency? ESO Research looks at dispatch protocols and patient outcomes to understand 911 prioritization measures

Study represents a significant step in enhancing emergency response amid rising call volume and resource constraints.

AUSTIN, Texas–(BUSINESS WIRE)–ESO, a leading data and software company serving emergency medical services (EMS), fire departments, hospitals, state and federal agencies, recently collaborated with eight EMS Systems and their dispatch centers to examine 911 prioritization systems. With increasing call volumes and limited resources, it is critical for EMS agencies to understand when a call can be safely held in a queue for response versus when a call requires immediate dispatch of an ambulance. This study represents a significant step in improving emergency response amid rising call volume and resource constraints, including workforce shortages.


Data for this research was sourced from the electronic health records of the participating EMS agencies. These agencies also receive patient outcome data from nearby hospital systems through ESO’s Health Data Exchange technology.

“Our research fills a critical gap in understanding how EMS systems can effectively manage emergency response in the face of escalating demands and staffing challenges,” said Dr. Brent Myers, Chief Medical Officer at ESO. “By analyzing dispatch information, on-scene findings by EMS, and emergency department outcomes, we’ve developed a reliable framework for identifying which calls can be safely referred to nurse advice, telemedicine, or held for non-emergent dispatch, ensuring that resources are allocated where they are most needed.”

Researchers looked at more than half a million 911 responses matched to hospital outcomes. Time-critical incidents requiring immediate ambulance response were defined by evaluating EMS interventions and the patient’s emergency department diagnoses. Researchers analyzed the data from two different perspectives: understanding the type of injury or illness and evaluating the severity of the injury or illness.

“Many EMS systems use standardized dispatch response prioritization systems designed to immediately dispatch appropriately resourced response units. However, most dispatch systems were not designed to identify which calls need an immediate response versus which can be safely held,” continued Dr. Myers.

Here are some key findings from the data:

  • EMS Performed time-critical interventions in 6% of responses.
  • Among patients transported by EMS, 12% had time-critical conditions diagnosed in the emergency department.
  • Incorporating EMS and hospital data, it appears that, conservatively, at least 8% of EMS requests could be safely referred to alternative resources or held for non-emergent dispatch.
  • In some cases, the type of injury or illness was more predictive than the assigned acuity level. Regardless of acuity, those with “Heart Problems,” and “Allergic Reaction” were more likely to have a time-critical condition, while dispatches for “Sick Person” were far less likely to have a time-critical condition.

The results from this study support programs like the one that Austin-Travis County EMS launched shortly after COVID-19, which is an initiative used every day, especially during peak response times.

“In Austin-Travis County, we’ve established the Collaborative Care Communications Center (C4) field triage program, which focuses on handling low-acuity calls without the need for ambulance or hospital services. Through this program, we analyze call patterns, especially during peak times like busy weekends, to effectively manage resources” explained Heidi Abraham, Chief Deputy Medical Director for Austin Travis County EMS.

“By validating our data through ESO, we are confident that our expanded triage program aligns with the study findings, demonstrating our ability to address low acuity calls with the right patient-centered resources,” continued Dr. Abraham.
