Although it makes up only about 1-2% of all emergency calls for help, sudden cardiac arrest (SCA) remains one of the most deadly—and one of the most hotly debated—topics in emergency services. Emergency Medical Dispatchers (EMDs) can play a critical role in improving survival rates for victims of SCA. In order to provide the most timely, effective care, EMDs must first identify that an SCA is occurring, then move quickly to provide instructions for bystander CPR. To support the achievement of these twin goals, the American Heart Association (AHA) has recently released proposed standards for...

Second-Party Caller Information for a Falls Case

Ivan Whitaker, MBA

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

While teaching a Medical Priority Dispatch System (MPDS®) refresher course in Canton, Illinois, USA, at the Canton County Sheriff's Office Dispatch Center, I was asked an interesting question by a student: "What do you do when a second party caller doesn't know the answer to your questions?" The student's question was inspired by a recent investigation request from the 911 center's local fire department involving a case dispatched as a BRAVO-level response to a fall patient. Emergency medical dispatchers (EMDs) use the MPDS to assign response determinant codes to incidents based...

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...

A Case with a Sting in the Tail

Mark Conrad Fivaz, MD

Aug 01, 2014|AEDR 2014 Vol. 2 Issue 2|Case Study

Clinical call handlers use a clinical decision support software system (CDSS) called the Emergency Communication Nurse System™ (ECNS™) to further triage calls considered eligible for secondary triage post the interaction the patient or caller had with the Emergency Medical Dispatcher (EMD). EMDs use a primary emergency triage system called Medical Priority Dispatch System (MPDS®) to triage callers accessing 911 services. This call involved a teenage boy calling 999 in England, UK, on behalf of his friend (also a teenage boy) who was stung on the palmar side of his right wrist by...

Triage Nurse in a 911 Center Effectively Handles Case of Insect Bites

Rick Roller, Mark Conrad Fivaz, MD

Mar 01, 2014|AEDR 2014 Vol. 2 Issue 1|Case Study

On June 26th, mid-morning, a 47 year old male patient called into the 911 center with a complaint of being bitten by insects all over his body. Initially the caller wanted an ambulance to take him to the emergency room (ER), but he had advised the emergency medical dispatcher (EMD) that the rash and bites had been going on for a while. In Louisville, all medical 911 calls are triaged at the MetroSafe 911 center by a certified EMD using the Medical Priority Dispatch System™ (MPDS®) software, ProQA®. The end result of the EMD triage is an assigned (alphanumeric) determinant code that...

A Silent But Deadly Aortic Dissection

Matthea Kristjansdottir

Mar 01, 2014|AEDR 2014 Vol. 2 Issue 1|Case Study

It was fairly early one day when a young man about 40 years of age called in to the 112 emergency line and asked for an ambulance. The reason was chest pains. He was very calm and "showed" no signs through the phone that he was in pain or any kind of distress. So I asked him if the patient was himself or if he had someone with him that he was calling for. He replied that he was indeed the patient, and when asked about the chest pain, he said that he had had some discomfort since late the night before and then again that morning. He had no history of any kind of heart or lung problems and...
