Priority Dispatch Corporation published an article in The Journal exploring the impact of cumulative trauma in emergency communications.

Priority Dispatch Corp. is the world leader in providing emergency dispatch protocol products as well as training and services. Our company has developed a comprehensive, systematic approach for triage systems for emergency calltaking centers. Our Medical Priority Dispatch System™ (MPDS®) has been in use for 45 years. Currently, the MPDS and it's counterparts, the Police Priority Dispatch System™, Fire Priority Dispatch System™, and Emergency Communication Nurse System™ are used in 60 different countries and have been translated into 31 different languages and dialects. The MPDS, PPDS, and FPDS exist in ProQA®, the most complete software solution in the industry, which leads the Emergency Dispatcher through a structured interrogation sequence of triage and recommends a response assignment. Prioritizing EMS responses helps avoid inappropriate response allocation and inappropriate use of lights-and-siren. Instead of a maximal response, it is better to send a response that is most suitable for the situation. In this way, the Priority Dispatch System not only saves money – it saves lives.
