Mar 04, 2020|AEDR 2019 Vol. 7 Issue 3|Original Research

Research on motor vehicle accidents (MVAs) is robust, though most focuses on prevention and treatment. Emergency medical experts now recognize telecommunications' vital role in the chain of survival; however, MVA research on telecommunicator impact on the MVA is limited. This study seeks to address that gap in research, examining the relationship between Emergency Medical Dispatch codes and on-scene findings. The objective of the study was to characterize all cases (based on determinant codes) triaged using the Medical Priority...

Caller's Ability to Understand "Responding Normally" vs. "Completely Alert" Key Question in a Brazilian Portuguese Version of an Emergency Medical Dispatch Protocol

Valeria De Cassia Pereira, RN, EMD-QI, Sara Scott, Maristela Uta Nakano, MD, MBA, Greg Scott, MBA, EMD-QI, Christopher Olola, PhD, Isabel Gardett, PhD, Srilakshmi Sangaraju, MS, Irena Weight, Daniel Ashwood, PhD, Edward Trefts, MFA, Brett Patterson, Jeff J. Clawson, MD

Alertness is important to assess during many medical emergencies; however, assessing alertness proves difficult in a non-visual emergency dispatch environment. Little is understood about how to best gather an accurate report of patient alertness during an interaction between callers and Emergency Medical Dispatchers (EMDs). The primary objective of the study was to compare two versions of a Key Question (KQ) intended to gain an accurate report of alertness, to determine whether either demonstrates a higher degree of caller...

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

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

Apr 03, 2018|AEDR 2018 Vol. 6 Issue 1|Original Research

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...

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...

Comparison of Emergency Medical Dispatcher Stroke Identification and Paramedic On-Scene Stroke Assessment

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

Mar 22, 2017|AEDR 2017 Vol. 5 Issue 1|Original Research

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...

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...

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)...

Assessing Call Demand and Utilization of a Secondary Triage Emergency Communication Nurse System for Low Acuity Calls Transferred from an Emergency Dispatch System

Dr. Mark Conrad Fivaz, Greg Scott, MBA, EMD-QI, Jeff J. Clawson, MD, Corike Toxopeus, PhD, Matt Zavadsky, MS, Kristen Miller, JD, Neal Richmond, MD, FACEP, Christopher Olola, PhD

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

Telephone nurse triage at the 9-1-1 dispatch point is relatively new in the United States despite its ability to significantly reduce expensive and scarce Emergency Medical Services (EMS) resource use and emergency department visits. A previous study investigated the distribution of 9-1-1-triaged call incident types within the Emergency Communications Nurse System (ECNS) and found that 9-1-1 triage systems yielded a variety of low acuity complaints that were handled by the Emergency Communications Nurse (ECN). This study explored the current and potential utilization...

Reprioritization of 911 Emergency Medical Calls Using Historical Clinical Data

Veer D. Vithalani, MD, FACEP, FAEMS, Greg Scott, MBA, EMD-QI, Christopher Olola, PhD

Sep 07, 2021|AEDR 2021 Vol. 9 Issue 2|Original Research

Emergency Medical Services (EMS) systems often utilize a structured approach to 911 call-taking and emergency medical dispatch (EMD). One such system, Medical Priority Dispatch System (MPDS®), categorizes 911 calls into EMD determinant codes based on problem and severity, with response priorities and resources determined at the local level through a predetermined response matrix. In this study, we proposed a methodology for utilizing historical clinical data to increase the accuracy of 911 call prioritization of patients with time-sensitive critical illness...
