Emergency medicine is the medical speciality concerned with the care of illnesses or injuries requiring immediate medical attention. Emergency medicine physicians specialize in providing care for unscheduled and undifferentiated patients of all ages. As first-line providers, in coordination with emergency medical services, they are primarily responsible for initiating resuscitation and stabilization and performing the initial investigations and interventions necessary to diagnose and treat illnesses or injuries in the acute phase. Emergency medical physicians generally practice in hospital emergency departments, pre-hospital settings via emergency medical services, and intensive care units. Still, they may also work in primary care settings such as urgent care clinics.
Emergency medical services (EMS), also known as ambulance services or paramedic services, are emergency services that provide urgent pre-hospital treatment and stabilisation for serious illness and injuries and transport to definitive care. They may also be known as a first aid squad, FAST squad, emergency squad, ambulance squad, ambulance corps, life squad or by other initialisms such as EMAS or EMARS.
An emergency medical technician is a medical professional that provides emergency medical services. EMTs are most commonly found serving on ambulances and in fire departments in the US and Canada, as full-time and some part-time departments require their firefighters to be EMT certified.
A paramedic is a healthcare professional trained in the medical model, whose main role has historically been to respond to emergency calls for medical help outside of a hospital. Paramedics work as part of the emergency medical services (EMS), most often in ambulances. They also have roles in emergency medicine, primary care, transfer medicine and remote/offshore medicine. The scope of practice of a paramedic varies between countries, but generally includes autonomous decision making around the emergency care of patients.
A medical emergency is an acute injury or illness that poses an immediate risk to a person's life or long-term health, sometimes referred to as a situation risking "life or limb". These emergencies may require assistance from another, qualified person, as some of these emergencies, such as cardiovascular (heart), respiratory, and gastrointestinal cannot be dealt with by the victim themselves. Dependent on the severity of the emergency, and the quality of any treatment given, it may require the involvement of multiple levels of care, from first aiders through emergency medical technicians, paramedics, emergency physicians and anesthesiologists.
An emergency department (ED), also known as an accident and emergency department (A&E), emergency room (ER), emergency ward (EW) or casualty department, is a medical treatment facility specializing in emergency medicine, the acute care of patients who present without prior appointment; either by their own means or by that of an ambulance. The emergency department is usually found in a hospital or other primary care center.
A certified first responder is a person who has completed a course and received certification in providing pre-hospital care for medical emergencies. Certified individuals should have received much more instruction than someone who is trained in basic first aid and cardiopulmonary resuscitation (CPR) but they are not necessarily a substitute for more advanced emergency medical care rendered by emergency medical technicians and paramedics. First responders typically provide advanced first aid level care, CPR, and automated external defibrillator (AED) usage. The term "certified first responder" is not to be confused with "first responder", which is a generic term referring to the first medically trained responder to arrive on scene and medically trained telecommunication operators who provide pre-arrival medical instructions as trained Emergency Medical Dispatchers (EMD). Many police officers and firefighters are required to receive training as certified first responders. Advanced medical care is typically provided by EMS, although some police officers and firefighters also train to become emergency medical technicians or paramedics.
The Seattle & King County Emergency Medical Services System is a fire-based two-tier response system providing prehospital basic and advanced life support services.
A medical director is a physician who provides guidance and leadership on the use of medicine in a healthcare organization. These include the emergency medical services, hospital departments, blood banks, clinical teaching services, and others. A medical director devises the protocols and guidelines for the clinical staff and evaluates them while they are in use.
A paramedic is a healthcare professional, providing pre-hospital assessment and medical care to people with acute illnesses or injuries. In Canada, the title paramedic generally refers to those who work on land ambulances or air ambulances providing paramedic services. Paramedics are increasingly being utilized in hospitals, emergency rooms, clinics and community health care services by providing care in collaboration with registered nurses, registered/licensed practical nurses and registered respiratory therapists.
Paramedics in Germany are the main providers of emergency care in emergency medical services in Germany. There exist two professional levels regulated by federal law, the Rettungsassistent and the Notfallsanitäter.
Advanced trauma life support (ATLS) is a training program for medical providers in the management of acute trauma cases, developed by the American College of Surgeons. Similar programs exist for immediate care providers such as paramedics. The program has been adopted worldwide in over 60 countries, sometimes under the name of Early Management of Severe Trauma, especially outside North America. Its goal is to teach a simplified and standardized approach to trauma patients. Originally designed for emergency situations where only one doctor and one nurse are present, ATLS is now widely accepted as the standard of care for initial assessment and treatment in trauma centers. The premise of the ATLS program is to treat the greatest threat to life first. It also advocates that the lack of a definitive diagnosis and a detailed history should not slow the application of indicated treatment for life-threatening injury, with the most time-critical interventions performed early.
In the United States, the paramedic is an allied health professional whose primary focus is to provide advanced emergency medical care for patients who access Emergency Medical Services (EMS). This individual possesses the complex knowledge and skills necessary to provide patient care and transportation. Paramedics function as part of a comprehensive EMS response under physician medical direction. Paramedics often serve in a prehospital role, responding to Public safety answering point (9-1-1) calls in an ambulance. The paramedic serves as the initial entry point into the health care system. A standard requirement for state licensure involves successful completion of a nationally accredited Paramedic program at the certificate or associate degree level.
Emergency nursing is a specialty within the field of professional nursing focusing on the care of patients who require prompt medical attention to avoid long-term disability or death. In addition to addressing "true emergencies," emergency nurses increasingly care for people who are unwilling or unable to get primary medical care elsewhere and come to emergency departments for help. In fact, only a small percentage of emergency department (ED) patients have emergency conditions such as a stroke, heart attack or major trauma. Emergency nurses also tend to patients with acute alcohol and/or drug intoxication, psychiatric and behavioral problems and those who have been raped.
In the United States, emergency medical services (EMS) provide out-of-hospital acute medical care and/or transport to definitive care for those in need. They are regulated at the most basic level by the National Highway Traffic Safety Administration, which sets the minimum standards that all states' EMS providers must meet, and regulated more strictly by individual state governments, which often require higher standards from the services they oversee.
Emergency medical services in France are provided by a mix of organizations under public health control. The central organizations that provide these services are known as a SAMU, which stands for Service d’aide médicale urgente. Local SAMU organisations operate the control rooms that answer emergency calls and dispatch medical responders. They also operate the SMUR, which refers to the ambulances and response vehicles that provide advanced medical care. Other ambulances and response vehicles are provided by the fire services and private ambulance services.
The following outline is provided as an overview of and topical guide to emergency medicine:
A mass casualty incident describes an incident in which emergency medical services resources, such as personnel and equipment, are overwhelmed by the number and severity of casualties. For example, an incident where a two-person crew is responding to a motor vehicle collision with three severely injured people could be considered a mass casualty incident. The general public more commonly recognizes events such as building collapses, train and bus collisions, plane crashes, earthquakes and other large-scale emergencies as mass casualty incidents. Events such as the Oklahoma City bombing in 1995, the September 11 attacks in 2001, and the Boston Marathon bombing in 2013 are well-publicized examples of mass casualty incidents. The most common types of MCIs are generally caused by terrorism, mass-transportation accidents, fires or natural disasters. A multiple casualty incident is one in which there are multiple casualties. The key difference from a mass casualty incident is that in a multiple casualty incident the resources available are sufficient to manage the needs of the victims. The issue of resource availability is therefore critical to the understanding of these concepts. One crosses over from a multiple to a mass casualty incident when resources are exceeded and the systems are overwhelmed.
Pre-hospital emergency medicine, also referred to as pre-hospital care, immediate care, or emergency medical services medicine, is a medical subspecialty which focuses on caring for seriously ill or injured patients before they reach hospital, and during emergency transfer to hospital or between hospitals. It may be practised by physicians from various backgrounds such as anaesthesiology, emergency medicine, intensive care medicine and acute medicine, after they have completed initial training in their base specialty.
Critical emergency medicine (CREM) refers to the acute medical care of patients who have medical emergencies that pose an immediate threat to life, irrespective of location. In particular, the term is used to describe the role of anaesthesiologists in providing such care.
