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 9-1-1 call-taking process, and dispatching them without delay, is crucial to delivering the required response and patient care. Determining the need for extrication using this protocol currently relies on the 9-1-1 caller's answer to a single key question in the protocol: "Is anyone pinned (trapped)?" The aims of this study were to determine the predictive value of the single key question...
In emergency dispatching, pre-alerts are used to send responders to calls prior to getting a final dispatch code—assigned using an emergency dispatch system. Although this dispatching process has been used for several years, no research studies have demonstrated its significant benefit, in general. However, a study published in 2013, showed that pre-alerts can be effectively used to reduce dispatch time for out-of-hospital cardiac arrests (OHCAs), which has the potential to improve overall patient outcome. As emergency calls are received, the call is entered in the Computer Aided Dispatch...
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 Priority Dispatch System each contains its own traffic and transportation incident protocol...
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 among five EMCCs in Liguria, Italy. The study retrospectively examined the assigned...
Providing information about possible weapons on scene is an essential objective of police dispatching and clearly valuable to officer safety. However, up to now, no information has been available about how often callers report weapons as "involved or mentioned" in an incident, what types of weapons are most commonly reported, or which incident types most commonly have reported weapons associated with them. The primary objective of this study is to determine which types of weapons are reported most often and on which Police Priority Dispatch System (PPDS®)...
The objectives of this study were to compare hospital-confirmed acute myocardial infarction (AMI) outcomes with emergency medical dispatch (EMD) low acuity cases and to identify any common characteristics of the AMIs assigned to those low-acuity codes. This was a retrospective study utilizing EMD, emergency medical services (EMS), and hospital discharge datasets, collected at two emergency communication centers in Salt Lake County, Utah. The study sample included all hospital-confirmed medical cases that arrived to the hospital via EMS. Primary outcome measures...
Although it makes up only about 1-2% of all emergency calls for help, sudden cardiac arrest (SCA) remains one of the most deadly—and one of the most hotly debated—topics in emergency services. Emergency Medical Dispatchers (EMDs) can play a critical role in improving survival rates for victims of SCA. In order to provide the most timely, effective care, EMDs must first identify that an SCA is occurring, then move quickly to provide instructions for bystander CPR. To support the achievement of these twin goals, the American Heart Association (AHA) has recently released proposed standards for...
Some have argued that there is no need for a dispatcher stroke evaluation because emergency medical services (EMS) responders can perform a more detailed, in-person stroke evaluation in the field. In fact, little or no research exists to determine whether dispatch stroke evaluations are actually redundant when compared with EMS field responder assessments. The purpose of this study is to determine whether some strokes identified by emergency medical dispatchers (EMDs) are not identified by field paramedics. The descriptive study utilized data from...
The findings of a recent study suggest that a patient's inability to complete all three tasks in a stroke identification tool used by Emergency Medical Dispatchers (EMDs) is a uniquely strong predictor of stroke. To examine the characteristics of the 17 cases in which the patient was unable to complete all three tasks in the Stroke Diagnostic Tool (SDxT). The retrospective descriptive study utilized stroke data from three sources in Salt Lake County, Utah, USA—Emergency Medical Dispatch, emergency medical services (EMS), and receiving hospitals—for...
