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 general. The goal of this study was to determine...

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...

We Got Rhythm with EJ Hinterman and Holly Downs

AEDR Editorial Team

Nov 14, 2017|Dispatch in Depth

Isabel Gardett talks with EJ Hinterman, captain of the Draper City Fire Department, and Holly Downs, a training coordinator for Salt Lake Valley Emergency Communications Center, about a metronome study they both recently participated in. They discuss the low percentage of bystanders who are comfortable with providing CPR, how to get people to perform CPR at the correct rate, and the value of emergency dispatchers and responders participating in research...

Characteristics of Acute Myocardial Infarction Cases Coded as Low-Acuity at Dispatch

Christopher Olola, PhD, Meghan Broadbent, MS, Isabel Gardett, PhD, Greg Scott, MBA, EMD-QI, Jeff J. Clawson, MD

Sep 12, 2017|AEDR 2017 Vol. 5 Issue 2|Original Research

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...

Communication Factors Associated with Stroke Identification During Emergency Calls: A Systematic Review

The first opportunity for prompt identification of a stroke in the prehospital environment often occurs when people telephone for emergency medical services. A better understanding of how callers and dispatchers communicate during emergency calls may assist dispatcher identification of stroke. To conduct a systematic review of the literature to determine communication factors associated with the identification of stroke during emergency calls. Six databases were searched (CINAHL, Cochrane, Embase, Informit, MEDLINE and PsychInfo). To meet...

Characterization of Hospital-Confirmed Stroke Evidence for Callers Who Were Unable to Complete Stroke Test Requests from the Emergency Medical Dispatcher

Christopher Olola, PhD, Greg Scott, MBA, EMD-QI, Isabel Gardett, PhD, Jeff J. Clawson, MD

Aug 28, 2016|AEDR 2016 Vol. 4 Issue 2|Original Research

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...

The Description of Hierarchy Bias Concept in Emergency Dispatch Coding and its Implications for Accuracy in Response and Outcome-based Studies

Jeff J. Clawson, MD, Rich Saalsaa, Christopher Olola, PhD, Jerry Overton

Aug 01, 2015|AEDR 2015 Vol. 3 Issue 2|Concept Papers

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...

Emergency Medical Dispatchers' Ability to Determine Obvious or Expected Death Outcomes Using a Medical Priority Dispatch Protocol

Ivan Whitaker, MBA, Christopher Olola, PhD, Corike Toxopeus, PhD, Greg Scott, MBA, EMD-QI, Jeff J. Clawson, MD, Bryon Schultz, BA, Donald Robinson, Christopher Calabro, Isabel Gardett, PhD, Brett Patterson

Aug 01, 2015|AEDR 2015 Vol. 3 Issue 2|Original Research

Emergency Medical Dispatchers (EMDs), at emergency communication centers that have implemented the Medical Priority Dispatch System® (MPDS) protocols, use scripted questions to interrogate people calling 9-1-1. Based on this interrogation, case determinant codes are assigned– to identify the specific patient condition and enable optimal allocation and deployment of resources to ensure appropriate field responses. MPDS determinant codes for both OBVIOUS and EXPECTED DEATH exist for patients that are clearly and irreversibly dead, or have a terminal illness accompanied...
