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...

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...

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)...

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

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...

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...

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

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

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...
