What is EMD ? ....Priority Dispatching?
 
 

Emergency Medical Dispatch is organized interrogation of persons calling for medical assistance. This is done by using a 35-card file system of medical protocols. These potocols are approved by the local medical authority. The protocols include specific questions, response configurations, and instructions for each medical, traumatic, or life threatening complaint in the system.

The instructions provided are not ad-libbed. The call taker reads them from the card file system. The instructions include Post Dispatch Instructions which are specific warnings, advice, and treatments that can be relayed to the caller before EMS arrives. They also inclued pre-arrival instructions. Pre-arrival instructions are medically approved and written instructions given to the caller by the trained EMD dispatchers. These instructions help to provide necessary assistance to the victim and control of the situation prior to arrival of EMS. They include airway management and obstruction, CPR, childbirth, bleeding control, and treatment of shock. All instructions are read word for word to the caller to the fullest extent possible. The questions 911 call takers are trained to ask are not to delay response of necessary responders but to enhance the responders' needs and to protect the caller or any nearby citizens. The answers that are provided are relayed to all of the responders who are en route. This relay of information provides the responder with vital information about the call itself, the nature of the problem, the people it is affecting, the severity of the situation, and the protection of the responder and anyone nearby. This information also helps the responders determine whether there is a need for lights and siren or if they can respond with the flow of traffic. The days when every responder went to every call with lights and siren are over. There are too many other lives that can be affected on the way to the call. Emergency vehicles are now more accountable than ever before regarding the use of lights and siren. There are many civil lawsuits that involve emergency vehicles involved in serious or fatal accidents. These persons and companies are held accountable for their actions and must justify their responses. The caller's answers to these questions help ensure the right unit is dispatched, the right number of units are sent, in the right mode of response. The EMS system as a whole also is utilized more than ever before. Often, there are more calls to dispatch than there are responders to send. The information obtained through careful interrogation of the caller allows the dispatcher to correctly prioritize the calls and send the units to the calls needing the quickest assistance first. Without the information, the calls would line up and be dispatched in the order they were received. The use of properly trained emergency medical dispatchers can positively influence all aspects of EMS response.

The Three Main Components of EMD are:

  1. Priority Dispatching
  2. Pre-arrival Instructions
  3. Quality Assurance

 

  1. Priority Dispatching is where you answer the questions presented by the dispatcher; those responses gear what type of response the emergency units respond.
    • E1- Priority Dispatch

Life Threatening emergency or potentially life threatening emergency
            - Immediate First Responder dispatch
                                          - Immediate ALS dispatch

  • E2 Emergency dispatch

                  Non-Life Threatening emergency

  • E3 – Urgent dispatch

                  Non-life threatening emergency with low potential for worsening injury or illness with delayed dispatch

  1. Pre-arrival instructions: The second component of EMD is providing the caller with pre-arrival instructions. Callers to the 911 system receive instructions from the dispatchers on how to care for the patient until paramedics arrive. These instructions include basic first aid intervention in preparation for paramedics arrival.  In addition, more advanced phone instructions for CPR, choking, and child birth can be given
  1. Quality Assurance:  The priority 911 program has an extensive quality assurance program which includes tape reviews of calls and on-line monitoring of dispatchers.  The quality assurance program evaluates all aspects of the EMS dispatch process including:
  • Structure-policies, procedures, nature codes
  • Process-activities of the system, compliance with the nature code cards
  • Outcome-evaluation of dispatch times, consumer surveys, dispositio

A continuing education program provides information on the latest improvements in the Priority 911 program along with a review of difficult calls identified by the quality review program.  A Priority 911 quality review committee consisting of dispatchers, EMS representatives, EOC administrators, and physicians, meets quarterly to discuss and make improvements in the system.
