US border counties: more trauma, more delays
Differences in EMS Calls, Delays, and Payer Types in U.S. Southern Border Counties and Non-Border Counties
Prehospital Emergency Care · Added 22 September 2026
Comparison of 421,877 EMS encounters in US border versus matched non-border counties — border areas carried more severe trauma and environmental exposures (25.5% vs 8.2%) alongside larger response and scene delays
- Study type
- Registry
- Design
- Retrospective analysis of national EMS registry data with matched county comparison
- Participants
- 421,877 EMS encounters across eight rural US counties (242,029 border; 179,848 comparison)
- Main finding
- Border counties had more severe trauma or environmental exposure cases (25.5% vs 8.2%), more falls from ≥20 feet, and moderate-to-large differences in payer type, response and scene delays
- Caveat
- US-specific border setting; secondary data analysis with unadjusted comparisons
- Bottom line
- Context only
Why it matters in Australia (Low relevance). transferability — US border-specific system pressures with no Australian analogue — descriptive interest only
Learning goal
Understand how geographic and socioeconomic context shapes case mix and system delays in ambulance response.

Qualitative needs assessment using the WHO prehospital assessment tool across 15 interviews with EMS and health bureau leaders in Hawassa, Ethiopia identified six recurring barriers — infrastructure, medicines/equipment, communication, community perceptions, workforce and, cutting across all of them, unclear governance and accountability — leaving services functioning as interfacility transport rather than true prehospital care.

IMPACC paramedic model cuts ED transport
Evaluation of 7,382 encounters under Toronto's IMPACC model, which lets specially trained paramedics redirect lower-acuity 911 callers — activated encounters had transport rates of 36% vs 82% for others (still 43% vs 79% after matching) but added roughly 24 minutes on scene, with 4% re-contact at 72 hours
