TCD System Goal
Improve health outcomes for Missourians
who suffer acute trauma, stroke or STEMI
by establishing
a Time Critical Diagnosis (TCD) System.
Prompt treatment reduces death and disability.
Why Time Critical Diagnosis Matters
Unlike trauma, ambulances often triage to the
nearest hospital for stroke or STEMI, not
necessarily a facility equipped to deliver
necessary level of care for stroke or STEMI
Patients who self-transport may not have the
knowledge to go to the right facility
Rural populations face unique challenges in
access to timely care
Creating a Time Critical Diagnosis
System
The Solution:
The Right Care

The Right Place
in the
The Right Time

Using Trauma System as a Model
Trauma System:
Improves Patient Outcomes and Saves Lives
- 50% reduction in preventable death rate after
implementation
- Decrease in cases of sub-optimal care from 32% to 3%
Improves Hospital Outcomes
- Better outcomes compared to voluntary system
- Cost Savings through more efficient use of resources
Improves Regional Outcomes
- Regional system accommodates regional and local
variations
Missouri Regulations
Stroke & STEMI
Four Levels of Center Designation
Level I
Functions as resource center within region
Level II
Provide care to high volumes of stroke and STEMI
patients
Level III Access into system in non-metropolitan areas,
more limited resources and generally refer to
higher level center
Level IV Access in rural areas, stabilize and prepare for
rapid transfer to higher level of care
Missouri Regulations
Stroke & STEMI
Voluntary process
Stroke/STEMI Program-24/7 (all levels)
Medical Director
Program Manager/Coordinator
Staff meet and maintain core requirements to

The Time Critical Diagnosis System
Concept
Dr. Bill Jermyn’s vision for emergency
medical care in Missouri introduced some
key concepts, including:
The Circle Concept
The Emergency Medical Care Systems
(EMCS) approach
The Time Critical Diagnosis System in
Missouri
Dr. Jermyn’s Circle

The Emergency Medical Care
System Concept
The EMCS Concept
Time critical diagnoses share some
fundamental principles.
The Emergency Medical Care System is built
upon these principles, which apply whether
you are dealing with trauma, stroke, STEMI, or
future time critical diagnoses.
This is the elegance of the Circle concept.
Bill Jermyn, DO, FACEP
The Emergency Medical Care
System Concept
Integrate public health, public safety, and the
healthcare systems into the Emergency
Medical Care System.
Make you think about the system design
for the patient, provider, and support future
needs.
Bill Jermyn, DO, FACEP
The Time Critical Diagnosis System
Concept
We work together towards the common goal
of improved patient care for those diagnoses
that are time dependent. We don’t do it
separately. Bill Jermyn, DO, FACEP
