  1. Emergency Medical Services EMS Overview & Medical Oversight

  2. Introduction • History of EMS • EMS System • Levels of training and abilities • Overview of system designs • Local system design • Medical control

  3. History of EMS 1917 Honolulu Police Department Ambulance

  4. History of EMS • Before 1966 • 1966 - 1973 • 1974 - 1981 • 1981 - Present

  5. Before 1966 • Jean Dominique Larrey • Napoleon’s Chief Military Physician • wounded treated on battlefield and horse drawn carriages constructed to carry the wounded • Civil War • First organized pre-hospital system in U.S. • Joseph Barnes, Johnathan Letterman - Military physicians • Union Army trained corpsmen - first “medics”

  6. Before 1966 • Civil War • Developed a transportation system • Post Civil War • Cincinnati, New York, London, Paris • Horse Accidents, fires - need for transport • Edward Dalton • Former Surgeon in Union Army • 1869 began New York City Ambulance • Interns staffed ambulances

  7. Before 1966 • World War I • Improved communications - signal boxes • Electric, steam, gasoline powered carriages • Thomas traction splint • Ambulances now equipped • Post World War I • Radios to dispatch ambulances • Volunteer rescue squad • Interns still on ambulance

  8. World War II • U.S. Entrance into WWII • Removed interns from ambulance • Deterioration of care - untrained • Little care, mostly transportation • Half of ambulances operated by mortuaries • Post WWII • CPR, defibrillation • 1966 Belfast Ireland Mobile CCU

  9. 1966: A Turning Point • National Academy of Sciences - National Research Council • Described pre-hospital care and compared it to military pre-hospital in Korean Conflict • Described lack of communication, lack of helicopter services, archaic ED’s • Led to the National Highway Safety Act

  10. National Highway Safety Act • Department of Transportation as Federal Governing authority by finances • Funded Training programs and national minimum standards of skills • Communications programs and equipment • Funded Ambulances, equipment, • Personnel and administrative cost • 1968 - 1979, $142 Million

  11. Other Federal Initiatives • Health Services and Mental Health Administration • Lead Agency for EMS within Department of Health, Education and Welfare (DHEW) • Physician Responder Programs • metamorphosed into “paramedic” programs • close physician supervision • mostly on-line medical control • Telemetry programs begun

  12. Public Law 93-154, 1973 • Goal to improve EMS on National Scale • 15 Elements flawed - idea of chain of survival • State control of EMS efforts • BLS and ALS Terminology spread • Communications • 1 in 20 ambulances voice communication • advocated 911 access and central dispatch

  13. EMS System • Access • First Responder • EMT / Paramedic • Medical Control • Transport to definitive care

  14. 911 System • Centralized access number • >90% of country covered • Enhanced System provides name, address, telephone number • Abuse of system

  15. Providers - Scope of Practice • First Responders • CPR • First Aid • Basic Airway Management • Emergency Delivery • Spinal Immobilization • Oxygen Administration • Assisted Ventilation

  16. Scope of Practice EMT - A • Scope of First Responders • On Scene Triage • Fracture Splinting • Extrication and Transport • MAST

  17. Scope of Practice EMT-I • Scope of EMT-A • EOA, Combi-tube • Orotracheal Intubation • Peripheral IV cannulation • Basic determination of death (obvious) • Defibrillation (AED)

  18. Scope of Practice - Paramedic • Needle cricothyroidotomy • Needle Decompression of pneumothorax • Defibrillation, Cardioversion • Administration of most drugs, antiarrhythmics, benzodiazepines, and narcotics

  19. Georgia EMS • No registered First Responder • EMT (Basic EMT) - national EMT-I • D50, Epi-pen • Cardiac Technicians - Closely approximates National Paramedic • Paramedic - Expanding Curriculum

  20. System Structure • Municipality • City or County run organization • Fire Department based • Hospital Based • Hospital owned and operated • County 911 provider • Private and volunteer • Combination and Tiered Response

  21. Response Systems • BLS EMS • ALS EMS • BLS EMS with ALS Back-up • Tiered Response • Fire BLS or ALS Response • ALS Transport Service • Police, Fire and ALS

  22. Medical Control • Direct (On-line) Medical Control • Direct physician to medic contact • Radio • Telephone • Off-Line Medical Control • Writing and approving protocols • Quality Assurance

  23. Protocols • Written standards • Do not require physician contact • Require a physician signature • Governed by local EMS council • Sparingly used in Region 6 EMS • Liberally used in most of U.S.

  24. Direct Medical Control • Telephone and Radio contact most common • Radio • “Key-up” 1-2 seconds before speaking • Speak clearly and slowly • Its not a telephone - most radio systems are Simplex not duplex • Break-up common making understanding difficult
