  • Where CMED came from
  • CMED Functions
  • Definitions
  • How it works Technologically
  • Everyday and not so everyday use
    • Hailing
    • Routine
    • MCI/Surge
  • Questions
  • Practical Evolutions
  • Post-Test
the beginning of cmed
The Beginning of CMED
  • The Federal Emergency Medical Services System Act of 1973
    • Established the concept of a Central Medical Emergency Direction (CMED) Center.
    • Funded by both private and public agencies including Department of Public Health and private hospitals.
  • A CMED Center
    • Is an entity that provides specialized communication functions
    • Connects hospitals and field medical first responders
functions of cmed
Functions of CMED
  • Compliance with state and appropriate regional EMS communications plans
  • Manage regional EMS channel use
  • Enable ambulance to hospital communication
  • Obtain ED care capabilities during an MCI and ED specialty capability including decontamination
  • Communicate with other public safety agencies as necessary
  • Request Regional Mass Casualty Support Units (MCI trailers)
  • Incoming out of area support
functions of cmed cont
Functions of CMED, Cont.
  • Request and coordinate distribution of EMS CHEMPAK supplies
  • Coordinate patient distribution during an MCI
    • Including but not limited to assigning patient destination
  • Coordinate requests for EMS resources
    • In conjunction with fire district control centers
  • Coordinate forward movement of patients during surge events
  • Coordinate with other Regional CMED Centers as needed

Regional Mass Casualty Support Unit (RMSCU)

(MCI trailer)

  • Mobile MCI treatment and support supplies
    • 13 trailers located across Massachusetts
    • Each trailer is equipped with supplies to treat 50-75 patients
    • Unit has available minimal EMS branch support supplies
    • Staffed by two providers from host agencies
    • For additional information go to http:// Any Decision on WEBLINK??

Ambulance Task Force

  • Any combination of ambulances, within span of control, with common communications and a leader
    • There are 58 Task Forces in Massachusetts
    • Task Forces are accessed through the Fire District Control Centers
    • 5 ambulances and a Leader or Alternate Leader make up a task force
    • Can be either ALS, BLS or a combination
    • Some Task Forces have an additional non-transport paramedic units assigned them
    • There are a total of 290 ambulances
    • Task Forces utilize the DCR radio network when traveling together

ED Care Capability

  • The number of red, yellow and green patients a hospital can care for during an MCI
    • CMED continually monitors the ED capability during the duration of an incident


  • The forward movement of patients during a high patient volume event
    • Evacuation from a nursing home or hospital
    • Influx of patients from disasters in other areas of the country or parts of the world
    • A Pan-flu event


  • Federally funded program providing nerve agent antidotes for large scale events
    • Stored at select hospitals throughout the Commonwealth
    • Designed for use during very large scale nerve agent exposures or organophosphate poisonings
    • Requested through CMED
    • Transported to staging area by EMS provider
contacting cmed
Contacting CMED
  • All communications with CMED begin here
    • The common hailing channel in all Regions is MED 4
    • This is true for everyday patches as well as declaring an MCI
  • When hailing CMED
    • Request Medical Control
    • CMED name x 2
    • Service and unit number
    • Reason for request
    • Physical Location
      • For Example: “Boston-CMED, Boston-CMED. This is Bedford A-2 requesting a priority one patch to the Lahey from Route 62”
routine radio reports to the emergency department
Make this report as clear, concise, and short as possible

Rule of thumb, no more than two minutes

When reporting a patients’ condition, the radio report should include the following



Chief Complaint (CC)

History of Present Illness (HPI)

Past Medical History (PMH)



Assessment- Include pertinent negatives

Treatment provided


Routine Radio Reports to the Emergency Department
radio communications with cmed mass casualty incidents
Radio Communications with CMEDMass Casualty Incidents
  • Contact CMED where incident occurred immediately on MED 4 upon determining an MCI – (the EMS Region of an event manages the event)
  • Using the mnemonic METHANE relay the following information;
    • Major incident declared
    • Exact Location - The precise location of the incident, staging area, if applicable
    • Type - The nature of the incident, including how many vehicles, buildings etc. are involved
    • Hazards - Both present and potential
    • Access - Best route for emergency services to access the site, or obstructions and bottlenecks to avoid
    • Numbers - Numbers of casualties, dead and uninjured on scene
    • Emergency Services - Which services are already on scene, and which others are required(MCI Trailer, Regional Staff, Task Force…)
  • Request that the surrounding hospitals be advised of incident
    • Request CMED to acquire the ED Care Capabilities
radio communications with cmed mass casualty incidents1
Radio Communications with CMEDMass Casualty Incidents
  • Request a channel assignment
    • Assigned channel is used by EMS to request additional resources per the ICS protocol
      • MCI Trailers, CHEMPACK, Task Force, Regional Support, etc.
    • Assigned channel is used by the Transport/Loading Supervisor
      • Transport/Loading coordinates distribution of patients through CMED
  • CMED Provides patient destination to Transport/Loading Supervisor for distribution of patients
    • CMED and the Transport/Loading Supervisor maintain a record of patient distribution to hospitals to include;
      • Patients tag numbers, priority, ambulance service and unit number, and hospital destination
      • EMS Branch, CMED, and Hospitals will reconcile records after incident is over

*Ambulances transporting patients from an MCI shall not contact CMED unless the patients conditions changes so that it is immediately life-threatening and needs to be redirected by CMED to a closer hospital*
