Any event overwhelming
available resources

Initial disasters often
compounded by poor planning
& communication, costing
time, resources & lives
• Q: What is the main distinction
in altering standards of care in a
“daily emergency” vs a
“disaster”?

I “Expanded Medical Incident”
 >10 critical, <50 patients
 Local resources available to treat injured

II “Major Medical Incident”
 >50 critical, <200 patients
 Regional resources available to treat injured

III “Disaster”
 >200 patients of any type
 Lack of regional resources available to treat injured
 State, Federal resources required

1830: Tornado warning sounded
for Albion community; 5
ambulances to “corners”

1845: 1st of 6 tornadoes touches
down

1855: Ambulance C reaches trailer
park, begins triage

1860: Funnel cloud sighted over
trailer park, emergency
evacuation occurs

1868: Tornado sets down 1 mile
from trailer park, evacuation
completed

Casualties:
 Trailer Park – 22 injured; 45
evacuated
 Community Hospital /
Nursing Home – 15 injured;
150 evacuated
 Albion College Freshman
Dorm – 25 injured

Disaster Issues:
 Chain of Command
 Location, Evacuation &
Transportation

Based on commonality
 Many organizations work as “One”
 Utilizes one system of integrative, standardized
procedures for rural, suburban, urban areas

“In an uncontrolled incident vast numbers of ‘walking
wounded’ (& non-patients) leads to a reverse triage effect
where patients with minor injuries present to hospitals
before the serious casualties arrive, swamping emergency
services to the detriment of the severely wounded”


“Contained” vs “Open”?
Hazard identification?
Secondary incident potential?
Immediate vs delayed emergencies?
Evacuation & Transportation Q’s:
 Secondary evacuation site? Third? Fourth?
 Access or egress?
 How do you transport more individuals than you have
physical space for?

Category 5 hurricane makes landfall
on 8/29
 Coastal regions under mandatory
evacuation for days but warnings
largely ignored

1st patients in Shreveport 8/28
 800+ patients arrive in 29 sorties of
C130s, Blackhawks, cargo planes &
ambulances in <24 hours
 Few “Walking Wounded” from New
Orleans
 Estimated 5-10,000 patients arrive
from Gulf Coast over next 5-10 days

Immediate Casualties:
 1,830 deaths
 750+ missing

Delayed Casualties:
 Unknown

In 3 months population of Shreveport doubles*
 Violent & gang-related crime quadruples
 Uninsured population with no “medical homes”

 Family & Home

Dynamic process in which patients sorted into groups,
priorities of care established & resources allocated

Sorting based on limited data & resources to get care to
those who will benefit from it the most (“Salvage”)

Objective framework for stressful & emotional decisions

Provides equal & rational distribution of casualties to
reduce burden on each to a manageable level

Sort patients based on physiologic
needs
 Is patient utilizing their own resources
to deal with their injuries?
 Which conditions most benefit from
limited resource expenditure?

Close to incident in a “safe” area

Assumptions:
 Medical needs outstrip immediately
available resources
 Additional resources soon available

Match patients’ current &
anticipated needs with available
resources

Incorporates:
 Physiologic reassessment
 Knowledge of resource availability

Goal is to distinguish between:
 Those needing initial treatment in a hospital
 Those needing initial treatment on scene
 Those needing no initial treatment, but at risk for complications
 Those needing no treatment

Goal is to optimize the
outcome of the individual

Incorporates:
 Sophisticated assessment &
treatment
 Further assessment of
available medical resources
 Determination of best venue
for definitive care


Gold standard for field adult multiple casualty triage

Problems:




Does not take resources into account
Some patients more “Red” than others
Uses a limited number of physical parameters
Not commonly used during daily operations

Green
 Minor or no injuries that can
wait for treatment

Green
 Minor lacerations, contusions,
sprains, superficial burns

Yellow
 Potentially serious injuries, but
stable to wait a short while for
medical treatment

Yellow
 Open abdominal wound, eye
injury, pulseless limb, fractures,
significant burns other than
face, neck or perineum

Red
 Life-threatening but treatable
injuries requiring rapid medical
attention

Red
 Airway obstruction, cardiorespiratory failure, external
hemorrhage, shock, open chest
wound, burns of face or neck

Black
 Dead or injuries incompatible
with survival in austere
conditions

Black
 GCS<8, burns >85% BSA,
multisystem trauma, signs of
impending death

Q: What are the most
useful tools in the
triage area?

Q: Easier to “upgrade”
or “downgrade” a
patients’ condition?

Q: How does triage
affect patient
disposition?

3 days warning that Category 5
storm headed directly for Saba

1 day prior all communication
shut off & islanders counted or
moved to “safe” locations

Georges slow-moving, with eye
lasting 8 hrs
 Wall of 140+ mph winds hit island
 Hurricane front wall lasts 1.5 days
 Hurricane back wall lasts 2 days

Casualties:
 Few buildings left intact
other than schools &
government buildings
 Majority of 1600
islanders with mild to
moderate injuries

Disaster Issues:
 Ham radio operator
killed
 Minimal water, food or
shelter or medical
supplies
 Who rescues the
rescuers?

MCI “triage” may extend days
to weeks past an incident

The WHO estimates that more individuals have indirect
morbidity & mortality post a major disaster than direct
results of the incident





No antibiotics or antivirals
No maintenance medications
No clean water source
No means of evacuation
Q: How does the rescuer overcome these obstacles?

At 0430 a chlorine leak
reported at Bossier KFC
chicken processing plant

MCI “Code” called
 Mayhem comically ensues

Casualties
 Initial reports of 100+
 15 contact injuries
 10 inhalation injuries

Disaster Issues
 Field casualty reports
 Weather reports
 “WMD” issues
 MCI Response & Panic

WMD triage models must include
decontamination plans for conventional,
chemical, radiological, or nuclear attacks

Difficulty of conducting assessments & care in protective gear

Biological agents impact triage & destination facility

Patterns of EMS calls may assist in identification of a occult biological
agent attack or a natural epidemic

First Watch Biosurveillance tool: www.stoutsolutions.com/firstwatch

Agent-specific triage dependent
upon suspicion of the agent’s use
 Neurotoxins: contact or inhalation
 Respiratory Toxins: inhalation

Very difficult to train & maintain readiness with multiple
agent-specific triage schemes

Agents cause “toxidromes” allowing outcome prediction
of outcome based on presenting symptoms & signs

Q: What is “SLUDGE”
Syndrome?

Q: Has anyone in this
room practiced
patient care in a Level
A or B suit?

EMS notified of MVC with
“multiple injuries”

1 BLS unit with ALS
intercept dispatched;
upon arrival found:
 2 adult DOAs
 2 adult, 1 teen critical
 1 adult mild injuries
 1 child critical
 3 children moderate injuries
 1 infant missing from scene

First on scene calls a “Code
Black”

6 BLS & 2 ALS units mutual aid
Multiple engines / Heavy Rescue
Helicopter
Police
Volunteers
Disaster Issues:
 Resource Allocation
 Panic
 Communication failures

Responders from non-local agencies
often not in contact with IC center

Increased use & number of private agencies contributes to
this problem

The KC Hyatt Skywalk Collapse post-disaster review noted
that at no point was communication established with
Incident Command, Triage or Transportation Officers, The
LZ Coordinator or Communications Center by one HEMS
crew for the 9 critical patients transported (KC Health Dept,
1981:7)

Emergency services required (personnel & equipment)

90 mins post event, 5080% of acute casualties
arrive at the ED
 1/3 critical
 2/3 mild to moderate injuries

3-6 hrs for casualties to be
treated in the ED before
disposition

To predict total casualties
each facility can expect,
double number of
casualties hospital receives
in the first hour

Q: How & who
determines what
resources needed for a
scene?

Q: Who is (are) your
mutual aid, & what
are their capabilities?

At 0846, American flight
11 directly impacts WTC
south tower

17 minutes later, United
flight 175 impacts WTC
north tower

Towers fall at 0959 & 1029
at same time reports
coming in of synchronized
attack on the Pentagon &
United flight 93

Casualties:
 2,750 deaths
 343 FDNY
 84 Port Authority
 23 PDNY

Of persons in the
towers when they
collapsed, only 20
pulled out alive

Disaster Issues:
 Communication
 Triage
 Scope of the Disaster
 Personal Involvement
of rescuers

Either cause or effect of
the disaster

Difficult to overcome as
infrastructure disrupted
or eliminated

Q: What are examples of
natural communication
failures?

Loss of infrastructure or system
incompatibility

Difficult to overcome if infrastructure
disturbed

System incompatibility easy to
overcome if IC is prepared

Q: What are examples of technological
failures?

Human error generally
the easiest to
overcome

Q: What are examples
of human failures?

“Bands” are collections of
neighboring frequencies

Cannot communicate if
different bands





Low (37-47 mHz)
High (250-255 mHz)
UHT (450-470 mHz)
UHF-TV (450-470 mHz)
800 mHz Band (806-902 mHz)
Military & Ham bands
PDAs, pagers & Blackberries
allow alerts & private
communications if tower intact

“Normal” emergencies use all available manpower &
supplies to save a few lives

In a “Disaster” the number of injured > ability to treat in
normal manner, therefore “Utilitarian Rule” governs
medical care
 Resource use focuses on saving as many lives as possible
 The greater good of the greater number rather than the particular
good of the individual

Looks good on paper…doesn’t work so well in real life
A. Jonsen and K. Edwards, “Resource Allocation” in Ethics in Medicine, Univ. of Washington School of Medicine

Scope does not matter
 343 firefighter vs 1
firefighter death is a tragedy
 Scope of large disasters
“numbs” the impact

Delayed response more
difficult to overcome than
immediate response
