Basic Medical Process : Paramedics and Emergency Room
Paramedics1. Arrives at scene (Patient
Care Report begin)2. Transport patient to
hospital3. Arrives at hospital4. Provide triage nurse of
their assessment of injury
ER Nurse5. Patient admits to hospital6. Triage nurse starts
comprehensive Triage Nursing Assessment
7. Prioritize patient based on CTAS score (level of severity)

Motivation• Current Emergency Response System– Radio/Telephone Communication– Paramedic and ER nurse triage– Falling behind to demand– National benchmark is 8 hours for admitting a
patient, and 4 hours for discharging a patient

Solution• Allow hospital to receive multiple inquiries– Efficient– Trouble-free– Reliable
• Allow hospital to receive information early and prepare for incoming patients
• Reduce redundancy• Enhance communication between Paramedics
and Nurses
