Persons Descriptions Reported to Emergency Police Dispatch

Identification of persons based on verbal descriptions is one of the key skills of police work. Gathering as much description information as possible immediately following the event—for example, at the point of emergency police dispatch—could substantially improve the accuracy of suspect descriptions, the ability to locate missing persons quickly, and other key outcomes of effective police work. : The primary objective of this study was to determine what amount and...

Comparison of EMD Selection of Sick Person Chief Complaint Protocol with On-Scene Responder Findings

The Emergency Medical Dispatcher’s (EMD’s) selection of the most appropriate Chief Complaint Protocol is one of the most important elements in emergency dispatching. Choosing the correct Chief Complaint ensures that the correct information is gathered, the correct instructions and help provided, and the right resources sent. The selection of the MPDS Sick Person Protocol is often one of the most difficult for EMDs. s: The primary objective of this study is to compare the...

Implications of Pre-Alerts for Medical Emergency Calls

In emergency dispatching, pre-alerts are used to send responders to calls prior to getting a final dispatch code. Some studies have showed that pre-alerts can effectively reduce dispatch time for out-of-hospital cardiac arrests, potentially improving overall patient outcome. However, there is also a potential risk in running lights-and-siren on non-fully triaged calls. Although pre-alerts have been used for several years, no research studies have demonstrated its benefit, in...

Predicting the Need for Extrication in Traffic Accidents Reported to 911: Is Anyone Pinned/Trapped?

Extrication activities at the scene of motor vehicle accidents (MVA) result in extended scene times and increase morbidity and mortality. Identifying the need for extrication-capable resources during the 911 call-taking process, and dispatching them without delay, is crucial to delivering the required response and patient care. Determining the need for extrication using the Traffic/Transport Incidents Protocol in the Medical Priority Dispatch System (MPDS®) (version 13.0...

The “Four-Second Rule” for Identifying the Active Silent 911 Caller

With advances in wireless technology, the volume of unintentional calls, or misdials, to 911 call centers has steadily increased over the past 10 years. While call centers have been working to manage call volume, there is very little systematic research on how to develop policy for handling Active Silent calls where callers may be unable to verbally communicate. s: The primary objective in this study was to first establish how dispatchers manage nuisance calls, and then...

Multi-Protocol Discipline Agencies Use Different Protocols To Process Traffic Accidents

Traffic incidents (collisions and crashes) are among the most common call types handled by Emergency Communication Centers (ECCs). They are also among the most complex call types because they represent such a range of possible situations. ECCs that handle calls in multiple disciplines (medical, fire, and law enforcement) may have multiple protocols available for handling traffic incidents because the Medical Priority Dispatch System, Police Priority Dispatch System, and Fire...

Evaluation Variability Of Emergency Medical Calls Among Emergency Medical Communication Centers In Liguria, Italy

The evaluation of emergency calls received by Emergency Medical Communication Centers (EMCCs) is the first and basic step for activating the chain of survival. It also represents an essential prerequisite for optimal response to and management of critical patients. : The objective of this study was to evaluate whether the introduction of a single, structured, and standardized emergency medical dispatch system provided a more uniform evaluation of all emergency calls...
