Rapid identification of out-of-hospital cardiac arrest (OHCA) and delivery of bystander chest compressions in patients with ventricular fibrillation are key elements in the chain of survival. The timeliness of dispatcher-assisted CPR may improve survival in such patients. The Medical Priority Dispatch System (MPDS©) has recently introduced a streamlined process for emergency medical dispatchers (EMDs) that provides early identification of OHCA and rapid delivery of chest compression instructions in version 13.0, known as the Obviously Not Breathing Fast Track (Fast Track) feature...

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...

Characterization of Call Prioritization Time in a Medical Priority Dispatch System

Greg Scott, MBA, EMD-QI, Christopher Olola, PhD, Corike Toxopeus, PhD, Jeff J. Clawson, MD, Adam Johnson, Bryon Schultz, BA, Kristen Miller, JD, Neal Richmond, MD, FACEP, Donald Robinson, Matt Zavadsky, MS, Lis Burnette, Tracey Barron, BS, Brett Patterson

Mar 07, 2016|AEDR 2016 Vol. 4 Issue 1|Original Research

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)...

Adequate chest compression (CC) depth is paramount for resuscitation outcomes. Elderly rescuers are often unable to achieve the required 5-6 cm CC depth; thus, we investigated new strategies to improve CC performance. To evaluate the effects of the Andrew Maneuver (four-hands CC) on the depth of CCs performed by elderly bystanders in the setting of simulated dispatcher-assisted cardiopulmonary resuscitation (DA-CPR). A randomized controlled trial conducted in December 2013. Sixty-eight lay rescuers aged 50–75 were randomized to intervention or control pairs (males and females separately)...

The Distribution of Recommended Care Levels by Age, Gender, and Trauma vs Medical Classification within the Emergency Communication Nurse System

Dr. Mark Conrad Fivaz, Jennie McQueen, RN, Tracey Barron, BS, Jeff J. Clawson, MD, Greg Scott, MBA, EMD-QI, Isabel Gardett, PhD, Brett Patterson, Matt Zavadsky, MS, Neal Richmond, MD, FACEP, Christopher Olola, PhD

Mar 22, 2015|AEDR 2015 Vol. 3 Issue 1|Original Research

An examination of the Emergency Communications Nurse-determined Recommended Care Levels (RCLs), for calls transferred for secondary nurse-triage has not been performed. The outcome of such an investigation would help to gain a more complete picture of the type of care ultimately recommended for these patients. The Emergency Communications Nurse System (ECNS) studied contained 22 RCLs, ranging from urgent levels, including a country-specific 3-digit number Emergency response (911), and Emergency care as soon as possible to less time-dependent, low priority levels, such...

Emergency Call to EMS in the United Kingdom for a 35-year-old Female Experiencing an Addison's Crisis.

Tracey Barron, BS

Aug 12, 2014|AEDR 2014 Vol. 2 Issue 2|Case Study

Addison's disease is a rare, chronic condition brought on by failure of the adrenal glands, affecting people of all ages. It affects the production of cortisol and aldosterone, both essential in the body's functioning. A very low level of cortisol can be life threatening, since cortisol regulates blood pressure and the immune system, balances the effect of insulin, and helps the body respond to stress. Aldosterone helps to control blood pressure and regulate salts in the blood. Symptoms of this disease usually include a general feeling of being unwell, lethargy and fatigue...

Characterization of Call Prioritization Time in a Police Priority Dispatch System™

David Warner, Shawn Messinger, Chris Knight, Greg Scott, MBA, EMD-QI, Jeff J. Clawson, MD, Isabel Gardett, PhD, Tracey Barron, BS, Mark Rector, Brett Patterson, Lazaro Guerra, Angela VanDyke, Christopher Olola, PhD

Aug 10, 2014|AEDR 2014 Vol. 2 Issue 2|Original Research

Time-to-dispatch in a 911 center continues to be a topic of much discussion in public safety. This study represents a first attempt to classify a subset of time-todispatch, call prioritization time, the time required to gather critical information prior to dispatching the call. The study characterizes call prioritization time in two Police dispatching agencies by determining overall median call prioritization time for all Chief Complaints (CCs) in the agencies studied, then by determining specific call prioritization times for the top five most commonly-used CCs...

Ability Of a Diabetic Problems Protocol to Predict Patient Severity Indicators Determined by On-Scene EMS Crews

Jeff J. Clawson, MD, Greg Scott, MBA, EMD-QI, Isabel Gardett, PhD, Brett Patterson, Tracey Barron, BS, Christopher Olola, PhD

Aug 05, 2013|AEDR 2013 Vol. 1 Issue 2|Original Research

Diabetes mellitus is a leading cause of human disease, with 25.8 million Americans affected. It is estimated that 7 million (27%) of these patients are still formally undiagnosed. Diabetes can cause chronic or sudden signs and symptoms, which often result in observers calling 911 for assistance. The Emergency Dispatcher's interpretation of these calls affects dispatch triage and pre-arrival patient care. To determine the relationship between the EMDs' assigned Medical Priority Dispatch System (MPDS) determinant codes and patient severity indicators as determined by paramedic (or EMT) on-scene...

Past, Present, and Future of Emergency Dispatch Research: A Systematic Literature Review

Isabel Gardett, PhD, Jeff J. Clawson, MD, Greg Scott, MBA, EMD-QI, Tracey Barron, BS, Brett Patterson, Christopher Olola, PhD

Aug 05, 2013|AEDR 2013 Vol. 1 Issue 2|Original Research

Emergency dispatch is a relatively new field, but the growth of dispatching as a profession, along with raised expectations for help before responders arrive, has led to increased production of and interest in emergency dispatch research. As yet, no systematic review of dispatch research has been conducted. This study reviewed the existing literature and indicated gaps in the research as well as potentially fruitful extensions of current lines of study. Dispatch-related terms were used to search for papers in research databases (including PubMed, MEDLINE, EMBASE, EMCARE, SciSearch, PsychInfo...

The Distribution Of Emergency Police Dispatch Call Incident Types and Priority Levels Within the Police Priority Dispatch System

Shawn Messinger, David Warner, Chris Knight, Greg Scott, MBA, EMD-QI, Mark Rector, Tracey Barron, BS, Angela VanDyke, Lazaro Guerra, Isabel Gardett, PhD, Brett Patterson, Jeff J. Clawson, MD, Christopher Olola, PhD

Aug 03, 2013|AEDR 2013 Vol. 1 Issue 2|Original Research

911 centers receive a wide variety of calls for police-related incidents. Using the Police Priority Dispatch System (PPDS®), a 911 Emergency Police Dispatcher (EPD) categorizes each incident with a specific Chief Complaint (CC) and prioritizes the case using a systematic alpha-numeric coding matrix. The wide variation in CC types and specific codes assigned can profoundly affect staffing and resource deployment decisions made by law enforcement agencies. However, the frequency of specific call types and priority levels in the PPDS has not been studied formally to date. The objective of...
