Emergency Medical Services (EMS) System: Pre‑Hospital & In‑Hospital Integration
EMS Definition
The Emergency Medical Services (EMS) system encompasses the coordinated continuum of pre‑hospital care (911 dispatch, first responders, EMTs/paramedics, transport) and emergency department/hospital‑based resuscitation and definitive care.
Key Components
- Public access (911/emergency communications)
- Medical direction & protocols
- Tiered response (BLS/ALS)
- Transport capabilities (ground, air)
- Hospital integration (trauma/stroke/STEMI centers)
- Quality improvement & data systems
Seamless handoff between field and hospital teams optimizes time‑sensitive outcomes.
