A majority of patients transported by emergency medical services (EMS) did not require immediate emergency care. However, EMS personnel struggled to accurately identify patients needing emergency transport without specific protocols.

Area of Science:

  • Emergency Medicine
  • Public Health

Background:

  • Emergency medical services (EMS) are crucial for acute care.
  • Assessing the necessity of ambulance transport is vital for resource optimization.

Purpose of the Study:

  • To determine the proportion of patients transported by EMS who do not need immediate emergency medical care.
  • To evaluate paramedic accuracy in identifying patients requiring immediate ambulance transport.
  • To identify patient characteristics for developing EMS transport protocols.

Main Methods:

  • A prospective cross-sectional study of 277 patients transported via ambulance.
  • EMS personnel prospectively rated the need for immediate transport.
  • Physician raters used predefined criteria to determine eligibility for non-ambulance transport.

Main Results:

  • 59.2% of patients did not require immediate emergency medical care.
  • Paramedic assessment showed a sensitivity of 22.1% and specificity of 80.5% for identifying need.
  • Abdominal pain and oxygen administration were associated with needing transport; young age was negatively associated.

Conclusions:

  • Most low-risk patients transported by EMS do not require immediate emergency care.
  • EMS personnel without specific protocols or training cannot reliably identify patients needing emergency treatment.
  • Few factors were identified to aid in developing transport protocols.
