INTRODUCTION 

Optimal patient care requires that the EMT-I understand the principles of multiple casualty incidents.  The following topics will be discussed during this lesson:

 

·                      Incident command system

 

·                      Patient triage

 

·                      MCI implementation and resources

 

·                      START

 

·                      EMT-I role in an MCI

 

·                      Appropriate patient care activities during an MCI

 

LESSON OBJECTIVES

At the end of this lesson the participants will be able to:

 

1.         Understand the purpose and function of an incident command system.

 

2.         Verbalize the purpose of triaging patients.

 

3.         Discuss the criteria for MCI implementation in L.A. County and identify the available     resources.

 

4.         Define the components of the “START” acronym.

 

5.         Identify appropriate patient care activities during an MCI.

 

6.         Discuss the role of the EMT-I in an MCI.

 

KEY VOCABULARY

·          MCI - abbreviation for Multiple Casualty Incident

 

·          Resources - all personnel, resources, apparatus, vehicles, and supplies available

 

·          Staging - collection of vehicles at a central location for distribution as needed

 

·          Triage - a system of sorting patients based on the severity of injury

 

 

KEY CONCEPTS 

The following section provides information and space for taking notes on the key concepts discussed by the instructor.

 

INCIDENT COMMAND SYSTEM

Purpose

·          To provide an organized framework to effectively manage MCI’s

·          To coordinate resources

·          To identify responsibilities and lines of authority

·          To provide an orderly means of communication and information processing

·          To provide a common terminology

·          To identify a process for transfer of command

 

Structure

·        Incident Commander: provides control and direction

·        Sector officer and personnel for each sector (depends on the nature and extent of the incident if each section will be operational)

·          Transportation

·          Treatment

·          Extrication

·          Staging

·          Supply

 

PATIENT TRIAGE

Purpose

·          To sort or prioritize patients to allow for the most effective use of limited resources

·          To quickly determine the number of victims and the overall severity of their injuries

 

Principles of Triage

·        The only interventions that are performed during triage are those that are immediately life saving (i.e. opening the airway, pressure to control bleeding)

·        Priority is given to the most seriously injured victims that are likely to survive.

·        Valuable resources are not used on patients that are likely to die due to the nature and severity of their injuries

·        Triage is a dynamic process and patient categorization may change.

·        Each victim should be triaged in less than 60 seconds

·        Each victim is triaged using the following

·          Ventilation

·          Perfusion

·          Level of Consciousness

 

Triage Categories (START Categories)

 

·        Minor

·          Walking around

·          Have them walk to a designated area

·          Complete assessment will be done when time and resources permit

·          Must be re-evaluated periodically to determine if triage status remains unchanged.

 

·        Delayed

·          No immediate life-threatening injuries

·          Respiratory rate less than 30

·          Capillary refill < 2 seconds or palpable radial pulse

·          Normal mental status

 

 

 

·        Critical Immediate

·          Critically injured victims requiring immediate transportation

·          Respiratory rate above 30 or needs assistance to maintain patent airway

·          Capillary refill > 2 seconds or absent radial pulse

·          Altered mental status

 

·        Dead/Non-Salvageable

·          Obviously dead or have mortal wounds

·          If ventilation is inadequate the rescuer will open the airway and remove debris

 

CRITERIA FOR IMPLEMENTING AN MCI

L.A. County Reference #519

 

·        Expanded Medical Emergency

·          5-15 patients with at least 5 critical

 

·        Major Medical Emergency

·          16-50 patients

 

·        Medical Disaster

·          More than 50 patients

·          Manageable with local resources

 

 

 

MCI Resources

 

·        MAC: “Medical Alert Center” located at the Department of Health Services

·          Used during multiple casualty incidents to coordinate efforts of prehospital care personnel with hospital resources

 

·        HEAR: Hospital Emergency Administrative Radio used for communication between the hospitals, prehospital personnel, and MAC

 

·        HERT: Specialized teams of physicians and nurses that can be mobilized to assist with on-scene medical management at MCI’s

 

START

Purpose

 

·          “Simple Triage And Rapid Treatment” (transport)

·          Quickly allows a few people to triage a large number of victims

·          Rapidly assess and categorizes victims which allows the scene to be sized up and resources mobilized rapidly

·          Limited medical training is required to make the simple triage decisions regarding ventilation, perfusion, and LOC

 

Patient Care Activities During START

 

·          Open the airway

·          Control profuse bleeding

 

Role of the EMT-I in Multiple Casualty Incidents

 

·          Know and understand your department MCI plan

·          Know and understand the L.A. County MCI plan

·          Be prepared to assume almost any role during an actual incident

·          Know your scope of practice and work within its parameters

·          Maintain essential equipment and supply inventories at all times

·          Seek professional stress debriefing following major incidents
