Triage
Instructor Name:
Title:
Unit:
Triage – from the French sort
In casualty management sorting of a large number of injured personnel is the 1st stage in establishing order
Triage sets the stage for treatment and eventuates in transport of the injured
Triage is not to be considered with finality
Triage categories change based upon
Number of injured
Available resources
Nature and extent of injuries(s)
State of hostile threat
Things change
Number of patients
Extent of resources
Condition of patient
Gets better
Gets worse
Transport arrives
If you have only 1 patient
That patient is Pri 1 Immediate regardless of anything else
There is no real need for triage
Once this number increases, the need for triage arises
Categories
Immediate
Threat to life/limb
A lightly injured is immediate if he can be returned to duty with immediate simple management
Urgent
Patient is at risk if treatment or transportation is delayed unreasonably
Delayed
No risk to life or consequence if more definitive care is not rendered quickly
Expectant
Regardless of the level of care rendered, patient is likely to expire
Tough call to make for unit personnel
START – triage technique
Simple treat/triage and rapid transport
All of you within the sound of my voice
Move towards me
Doesn’t work well in no/low light or excess noise

Triage
Objectives – Upon completion of this block of instruction the student will be able to:
Triage
Definition –
“To Sort”
From the French word, “trier”
Has been defined as “doing the greatest good for the greatest number” BUT triage is simply a sorting PROCESS that when applied creates a situation that allows for “doing the greatest good for the greatest number”
Triage
What are the OBJECTIVES of doing Triage?
Rapid sorting of the more serious patients from those less serious to facilitate the rapid care of the more serious patients
When problems exceed resources, triage should facilitate “doing the greatest good for the greatest number”
Bring order to chaos thus facilitating the care of all patients
Triage
What is the PROCESS?
Sorting into categories for evacuation and treatment
What are the DECISIONS?
How will the patients be sorted – who goes in which category?
What will be done to/with the patients when sorted?
What factors AFFECT/CHANGE the decisions?
Resources
Circumstances
Triage
Triage
“Military” Disasters Occur In Civilian Settings
Triage
And… “Civilian” disasters occur in military settings
Triage
Military vs. Civilian – Are there differences?
Continuing risk to medical care providers
Can occur in both situations
More common in combat/military triage
Resource limited
Can occur in both situations
More common in combat/military triage
“Reverse” Triage Situation
Care provided first to those who when treated can be quickly returned to duty
Usually only in a military situation but could occur in a civilian MASCAL situation (when “Group” survival is at stake)
TRIAGE
– A DYNAMIC
NOT
A STATIC PROCESS
WITHIN THE MILITARY ECHELONED
MEDICAL CARE SYSTEM, TRIAGE OF
CASUALTIES OCCURS (OR SHOULD), AT A
MINIMUM, AT EVERY ECHELON
Triage
Surgical Prioritization Involves –
Recognizing
Which patients require surgery to save life/limb/sight
Knowing
Numbers of OR’s, doctors, nurses, expendables, blood (Resources) each operation requires
Resources (manpower, equip, expendables, blood etc) required to provide post-op care
How long each operation will take (Time as a resource)
The resources that each operation will consume (Must consider manpower as a consumable resource)
Probability of successful surgery
Triage
The Goal of Surgical Prioritization
Selection of cases with the highest probability
of success that consume the least amount
of resources.
Make a decision – – and go with it!
Once a MASCAL situation has been declared don’t wait for the situation to evolve further before making a decision.
Making decisions is more important than what decisions are made.
Respect the Triage Decision
Triage
Triage Categories used in ICRC Hospitals
Category I – Priority for Surgery
Patients who need urgent surgery and who have a good chance of satisfactory recovery
Category II – No Surgery
Patients with wounds so slight that they do not need surgery AND…
Patients who are so severely injured that they are unlikely to survive
Category III – Can Wait For Surgery
Patients who need surgery but not urgently
Triage
MILITARY TRIAGE DECISIONS ARE INFLUENCED BY:
NUMBERS OF PATIENTS AND THEIR MEDICAL PROBLEMS
NUMBERS OF EXPENDABLE AND NON-EXPENDABLE MEDICAL SUPPLIES AND CAPABILITIES OF MEDICAL TREATMENT FACILITIES
NUMBERS AND CAPABILITIES OF MEDICAL PERSONNEL
Triage
MILITARY TRIAGE DECISIONS ARE INFLUENCED BY(CONT):
NUMBERS AND CAPABILITIES OF EVACUATION ASSETS
TACTICAL SITUATION
WEATHER
OTHER
Triage
EVACUATION PRIORITIES
PRIORITY I – URGENT EVACUATION WITHIN 2 HOURS
PRIORITY IA – URGENT SURGICAL EVACUATION TO NEAREST SURGICAL FACILITY WITHIN 2 HOURS
PRIORITY II – PRIORITY EVACUATION WITHIN 4 HOURS
PRIORITY III – ROUTINE EVACUATION WITHIN 24 HOURS
PRIORITY IV – CONVENIENCE
MASCAL
Field Response
What / Who do you send to the disaster site?
Equipment
Type – Stick with the basics
Dressings
Backboards/litter with straps
Tourniquets
Airways / suction devices
Quantity (lots)
Personnel
Type (Surgeon, EM…)(MD, Nurse, PA, EMT-P…)
Quantity
MASCAL
Actions on the scene
Safety and site security FIRST
Survey the scene
Estimate number and type of casualties quickly
Transmit brief initial report to Med Tx Facility
Request additional equipment (#/type) and personnel (#/type) as required
MASCAL
Actions on the scene (cont)
Quickly choose a casualty collection point based upon:
Proximity to patients
Proximity to potential helicopter landing site
Safety – Distance from potential hazards, secure
Geography – Large enough and appropriate for conduct of Geographic Triage) Separate sites for –
Immediate (next to transportation)
Delayed
Minimal
Expectant
Deceased (out of sight of other victims)
MASCAL
Actions on the scene (cont)
Collect all ambulatory patients at CCP by instructing them to walk to CCP
These patients are mostly in the minimal category although some may be delayed
What they are NOT is in the Immediate / Expectant (except in some burn cases) / Dead categories
MASCAL
Actions on the scene (cont)
Put one of the “walking wounded” in charge of ambulatory patients if limited manpower at scene
Most important responsibility is to maintain accountability and keep patients from leaving CCP
If more than one medical responder divide the scene into areas of responsibility and proceed to rapidly assess / treat / triage all remaining patients who were unable to walk to the CCP
MASCAL
Actions on the scene (cont)
Initially treat ONLY readily correctable airway problems and obvious external, potentially life-threatening, bleeding
No treatment for pulseless /apneic patients.
Place comatose patients in lateral decubitus position – then move on
Apply triage tag to identify location in CCP where patient is to be taken
MASCAL
Actions on the scene (cont)
Have non-medical bystanders and uninjured or minimally injured patients at the scene act as litter bearers (at least one experienced litter bearer / team) and move patients to CCP
Triage Officer at CCP sorts (“triages”) patients into separate geographic location based on tags
Performs rapid reassessment and changes triage category as required
MASCAL
Actions on the scene (cont)
Move rapidly from one patient to next – only identify and if possible quickly treat life threats
Identify ALL patients
Avoid becoming involved in prolonged procedures
Avoid becoming distracted by distraught, minimally injured patients
Pay attention to administrative concerns – Keep track of ALL patients (Trust me – you’ll be glad you did)
MASCAL
Actions on the scene (cont)
Transportation Considerations / Decisions
Do you put all immediate patients on the first available ambulance?
Do you send one of your health care providers if there is no medical care on the transport
To what facility do you send the ambulance?
Travel time
Level I, II, III trauma center?
Do you wait for a helicopter?
How secure is the route of travel?
MASCAL
Medical Treatment Facility Actions
Maintain Communication with the response team
Identify the scope of the problem
Identify the need for additional resources at the scene
Medical
Security
Administrative
Transportation – Ground / Air
Arrange for helicopter transportation as appropriate
MASCAL
Medical Treatment Facility Actions (cont.)
Notify higher HQ and other medical facilities of the situation and request that they standby
Activate Medical Treatment Facility disaster response plan
Call in additional staff / keep staff in hospital at end of shift
Clear receiving area of all stable patients and set up additional beds as required
Cancel any non-emergent surgery
Clear OR’s ASAP
Prepare hospital beds
Request higher echelons preposition ambulance at your medical treatment facility.
MASCAL – Major Teaching Points
When ability to provide medical care is overwhelmed – Bringing organization to the disaster site is the most important action.
Avoid the overwhelming impulse to rush in and being to take care of first patient you come upon
Make sure that you do not become a casualty yourself
MASCAL – Major Teaching Points
Remember – All the resources that you have to deal with a disaster did not come with you to the scene
Supervising medical care and ensuring the proper evacuation order and disposition of patients may not be glamorous but it will ultimately be the most important
Keeping track of the disposition of patients may seem like a waste of manpower but its not – trust me.
Triage
Immediate (examples – not all inclusive)
Airway
Generally either must be addressed immediately at which point patient becomes either
DELAYED
DEAD
Some exceptions
Breathing
Correctable on the scene – ie. tension pneumothorax which when treated may turn patient from IMMEDIATE to DELAYED
Uncorrectable on the scene – ie. large pulmonary contusion/flail chest with hypoxia
Needs URGENT EVACUATION
Triage
Immediate (cont.)
Circulation
Exsanguinating hemorrhage
External – usually correctable with a tourniquet and/or direct pressure at which point patient becomes DELAYED
Internal – URGENT EVACUATION
Cardiac Tamponade
Even when treated with pericardiocentesis patient remains IMMEDIATE because underlying cause is wound to the heart
Triage
Immediate (cont.)
Disability
Closed head injury with deteriorating mental status
URGENT EVACUATION required
Triage
Delayed (examples – not all inclusive)
All injuries that require surgery but for which a delay of 4-8 hours will not cause loss of life/limb/sight
Penetrating abdominal wounds – hemodynamically stable
All fractures requiring ORIF – hemodynamically stable
Spinal cord injury – hemodynamically stable
Triage
Minimal (example – not all inclusive)
Minor soft tissue wounds not requiring surgical intervention
Non-displaced, min. angulated, closed fractures of the upper extremities or digits
Triage
Expectant
When resources are adequate no patients are made expectant
The creation of this category presumes inadequate resources and the types of patients included in this category is largely dependent on the ratio of resources/patients – the lower the ratio, the more patients in this category.
Examples:
> 50% TBSA 2nd and 3rd degree burns
Unresponsive patient with an open head wound and exposed brain
Documented exposure to > 500 RADs and immediate signs of radiation sickness
