Emergency medical dispatch

Last updated

Emergency Medical Dispatch (EMD) refers to a system that enhances services provided by Public Safety Answering Point (emergency) call takers, such as municipal emergency services dispatchers. It does so by allowing the call taker to quickly narrow down the caller's type of medical or trauma situation, so as to better dispatch emergency services, and provide quality instruction to the caller before help arrives.

Overview

Based on specific question-and-answer logic trees ("systematized interrogation"), the dispatcher is able to determine a problem type and priority for the call, and use that information to [1] [2] [3]

Implementation

Many countries have a national EMD or DLS program, sometimes with a designated system provider, either mandatory or optional. Others may have a national curriculum or accreditation program, or the program may be designated by local jurisdictions at the state or province level. Not all jurisdictions have any sanctioned EMD or DLS system in place, and not all emergency call centers have EMD or DLS. There is some controversy over using these systems, especially when non-medical staff man the phones. [4]

EMD may be guided by computer software, or flashcard-books (often color-coded, with page cross references to help further narrow down the phone diagnosis and/or treatment, and dispatch protocol). Such manual systems have been likened to recipe cards.

The dispatch effort guided by EMD may indicate call severity, resource type (basic life support or paramedics), declaration of a multiple casualty incident (MCI), responder emergency mode (e.g., permission to use lights and sirens), call priority, and hospital or health department notification.

The on-phone instruction effort guided by EMD may help the caller or other bystander to perform CPR or other lay basic life support, provide instruction on how to aid the responders to reach the patient, evacuation instructions, or other forms of care or safety instruction.

Adopted programs

In the United States, the Medical Priority Dispatch System (MPDS), Criterion-Based Dispatch, and Computer aided call handling (CACH) are common protocols.

In the United Kingdom, AMPDS is one of two Department of Health and Social Care approved computer programs for 999/112 medical emergency call triage; used across Scotland, Wales, Northern Ireland and parts of England. In England, NHS Pathways is the alternative system and it is used by five of the eleven regional ambulance services.

Emergency telephone number telephone number that allows caller to contact local emergency services for assistance

Most public switched telephone networks have a single emergency telephone number that allows a caller to contact local emergency services for assistance. The emergency number differs from country to country; it is typically a three-digit number so that it can be easily remembered and dialed quickly. Some countries have a different emergency number for each of the different emergency services; these often differ only by the last digit.

Dispatchers are communications personnel responsible for receiving and transmitting pure and reliable messages, tracking vehicles and equipment, and recording other important information. A number of organizations, including police and fire departments, emergency medical services, motorcycle couriers, taxicab providers, trucking companies, railroads, and public utility companies, use dispatchers to relay information and coordinate their operations. Essentially, the dispatcher is the "conductor" of the force, and is responsible for the direction of all units within it.
