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...
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...
While Structure Fire is not the most common Chief Complaint handled by Emergency Fire Dispatchers (EFDs), the high death toll and other serious consequences that result make structure fires one of the most important types of calls EFDs handle. The time needed to appropriately and effectively prioritize these calls can be evaluated using a time standard called Call Prioritization Time (CPT). In this study, we evaluate CPT for centers using the Fire Priority Dispatch System (FPDS). The primary objective in this study was to determine CPT for the FPDS...
Based on known unpublished sources (e.g. emergency communication center managers, training officers, dispatchers), emergency communication centers (ECCs) around the world provide training for new emergency dispatchers and continuing dispatcher education. However, little information has been collected, or shared, between ECCs regarding specific training methods that are being used, which methods are successful, and what factors influence their success. The objective of this study was to describe what training methods are currently being used in emergency...
Measurement is a critical part of testing and implementing changes as well as identifying areas for further research, in prehospital care and dispatch. Kaunas, the second largest city in Lithuania, implemented the Medical Priority Dispatch System™ (MPDS®) to improve the efficiency, timely availability, consistency, and reliability of dispatch data and information. This in turn facilitated a research study into the care of cardiac arrest patients. Measurement is a critical part of testing and implementing changes, as well as identifying areas for further research...
Expanding the role of evidence-based practice (EBP) in emergency medical services is a matter of increasing importance to researchers and practitioners alike. However, this movement toward EBP has not yet been applied to one critical area of prehospital care: emergency dispatching. The primary reason for this gap is that emergency dispatchers (EDs) struggle to develop a research culture able to produce enough well-conducted studies to move toward true EBP. One starting point with documented potential for building the research capacity in a field is to develop...
Emergency Medical Services (EMS) agencies have a pressing need to understand call prioritization time (CPT), a key sub-component of call processing time in Emergency Medical Dispatch, as it impacts response time to specific cases and overall EMS agency response time performance. The objective of this study was to determine median CPT by dispatch priority level and Chief Complaint type. This retrospective study included data from six emergency communication agencies, each accredited by the International Academies of Emergency Dispatch (IAED)...
The value of dispatch in modern Emergency Medical Services (EMS) systems cannot be understated. Among many other roles, an Emergency Medical Dispatcher (EMD) is responsible for accurate response selection. Response is based on EMD-assigned dispatch codes upon completion of caller-interrogation questions in a dispatch protocol system. When two or more signs, symptoms, or situational conditions are encountered in a calltaker evaluation, but are assigned and reported as a single, dispatch-defined code descriptor during the call-taking process by an EMD, a data hiding...
