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

• 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

• 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)

SURGICAL PRIORITIZATION,

WHICH, PRIMARILY INVOLVES A

DETERMINATION OF OPERATIVE

PRIORITY, IS NOT TRIAGE

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 probabilityof success that consume the least amountof 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 IN A DISASTER IS A MULTI-DISCIPLINARY PROCESS. IT IS BEST CARRIED OUT BY SOMEONE WHO IS FAMILIAR WITH:

•SURGICAL, MEDICAL, AND PSYCHIATRIC EMERGENCIES

•ALL THE PRE-HOSPITAL AND HOSPITAL-BASED MEDICAL AND LOGISTICAL RESOURCES NECESSARY TO EVACUATE AND PROVIDE CARE FOR A LARGE NUMBER OF CASUALTIES

BY DEFINITION, TRIAGE IN A DISASTER /

MASCAL SITUATION MEANS THAT LESS

THAN THE NORMAL STANDARD OF

CARE WILL BE PROVIDED FOR

MANY PATIENTS.

EXAMPLE: 

FAILURE TO PROVIDE COMPLETE

CONTROL OF THE CERVICAL SPINE IN A

PATIENT WITH MULTIPLE BLUNT TRAUMA

INJURIES IS CONSIDERED MALPRACTICE

EXAMPLE 

COMPLETE CERVICAL SPINE

IMMOBILIZATION IS VERY TIME AND

RESOURCE CONSUMING. THE TIME

AND RESOURCES REQUIRED TO

STABILIZE A CERVICAL SPINE MAY

MEAN THAT OTHERS MAY DIE. 

ADHERING TO THE PRINCIPLE OF

DOING THE GREATEST

 GOOD FOR THE GREATEST NUMBER

MAY REQUIRE THAT LESS

THAN FULL CERVICAL SPINE

 IMMOBILIZATION BE PERFORMED

REMEMBER 

IF IT WASN'T ALL "SCREWED" UP 

IT WOULDN'T BE A DISASTER

REMEMBER 

NOT ONLY MAY CHANGES IN A PATIENT'S 

MEDICAL CONDITION RESULT IN A CHANGE 

IN HIS / HER TRIAGE CATEGORY BUT A 

CHANGE IN AVAILABLE RESOURCES MAY ALSO 

RESULT IN A CHANGE IN TRIAGE CATEGORY

CAN YOU THINK OF A SITUATION 

WHERE IT WOULD EVER BE APPROPRIATE 

TO NEGLECT THE MANAGEMENT OF THE 

MOST SERIOUSLY WOUNDED IN ORDER TO 

TREAT THOSE WITH MORE MINOR INJURIES?

REMEMBER 

A TRIAGE SITUATION IS NOT 

DETERMINED BY A SET NUMBER OF 

PATIENTS BUT RATHER BY A MISMATCH 

OF RESOURCE REQUIREMENTS WITH  

RESOURCE AVAILABILITY. A TRIAGE 

SITUATION MAY EXIST WHEN THERE ARE 

ONLY TWO PATIENTS

THE DECISION TO NOT RESUSCITATE

A CRITICALLY INJURED PATIENT WHEN

THERE ARE RESOURCES AVAILABLE TO

DO SO IS NOT THE SAME AS PLACING

A PATIENT IN THE EXPECTANT

CATEGORY IN A DISASTER SITUATION

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

TERMINOLOGY 

CIVILIAN USE OF THE WORD 

"TRIAGE" IS OFTEN NOT 

THE SAME AS THE MILITARY 

USE OF TRIAGE

IN A MULTI-CASUALTY INCIDENT WHERE  

THERE ARE ADEQUATE RESOURCES THE  

GOAL IS TO RAPIDLY AND EFFICIENTLY 

IDENTIFY PATIENT NEEDS AND THEN TO 

MATCH THE RESOURCES WITH THE

PATIENTS WHO REQUIRE THEM

IN A DISASTER SITUATION WHERE 

THERE ARE LIMITED RESOURCES THE 

GOAL IS TO IDENTIFY PATIENT NEEDS 

AND THEN TO DISTRIBUTE THE RESOURCES 

IN A MANNER THAT PROVIDES THE BEST

CARE FOR THE MOST POSSIBLE PATIENTS

PROBLEMS WITH STANDARD

DON'T CONFUSE TRIAGE 

CATEGORIES WITH 

EVACUATION PRIORITIES

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

TEACHING POINTS

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
