3% of Patients Account for 16% of U.S. EMS Responses, ESO Study Finds

  • ESO's study of 9.5M EMS encounters found 3% of patients drove 16% of all responses, with high utilizers calling back within a median of 10 days.
  • Very-high utilization patients were transported more often (83%) but admitted to hospitals less frequently (40% less likely).
  • Medicaid patients and those in socioeconomically vulnerable communities showed three times higher odds of very-high EMS utilization.
  • Diabetes patients were twice as likely to experience high EMS utilization, suggesting prevention efforts could reduce burden.

The study highlights a critical inefficiency in U.S. emergency medical services, where a small subset of patients disproportionately consumes resources. This underscores broader industry trends toward value-based care and population health management, particularly for Medicaid and vulnerable populations. The findings could drive significant policy changes aimed at reducing costs while improving patient outcomes through targeted interventions.
