Emergency medicine is the medical speciality concerned with the care of illnesses or injuries requiring immediate medical attention. Emergency physicians (often called "ER doctors" in the United States) 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. Sub-specializations of emergency medicine include; disaster medicine, medical toxicology, point-of-care ultrasonography, critical care medicine, emergency medical services, hyperbaric medicine, sports medicine, palliative care, or aerospace medicine. Various models for emergency medicine exist internationally. In countries following the Anglo-American model, emergency medicine initially consisted of surgeons, general practitioners, and other generalist physicians. However, in recent decades it has become recognised as a speciality in its own right with its training programmes and academic posts, and the speciality is now a popular choice among medical students and newly qualified medical practitioners. By contrast, in countries following the Franco-German model, the speciality does not exist, and emergency medical care is instead provided directly by anesthesiologists (for critical resuscitation), surgeons, specialists in internal medicine, paediatricians, cardiologists or neurologists as appropriate. Emergency medicine is still evolving in developing countries, and international emergency medicine programs offer hope of improving primary emergency care where resources are limited. Scope Emergency medicine is a medical speciality—a field of practice based on the knowledge and skills required to prevent, diagnose, and manage acute and urgent aspects of illness and injury affecting patients of all age groups with a full spectrum of undifferentiated physical and behavioural disorders. It further encompasses an understanding of the development of pre-hospital and in-hospital emergency medical systems and the skills necessary for this development. The field of emergency medicine encompasses care involving the acute care of internal medical and surgical conditions. In many modern emergency departments, emergency physicians see many patients, treating their illnesses and arranging for disposition—either admitting them to the hospital or releasing them after treatment as necessary. They also provide episodic primary care to patients during off-hours and those who do not have primary care providers. Most patients present to emergency departments with low-acuity conditions (such as minor injuries or exacerbations of chronic disease), but a small proportion will be critically ill or injured. Therefore, the emergency physician requires broad knowledge and procedural skills, often including surgical procedures, trauma resuscitation, advanced cardiac life support and advanced airway management. They must have some of the core skills from many medical specialities—the ability to resuscitate a patient (intensive care medicine), manage a difficult airway (anesthesiology), suture a complex laceration (plastic surgery), set a fractured bone or dislocated joint (orthopaedic surgery), treat a heart attack (cardiology), manage strokes (neurology), work-up a pregnant patient with vaginal bleeding (obstetrics and gynaecology), control a patient with mania (psychiatry), stop a severe nosebleed (otolaryngology), place a chest tube (cardiothoracic surgery), and conduct and interpret x-rays and ultrasounds (radiology). This generalist approach can obviate barrier-to-care issues seen in systems without specialists in emergency medicine, where patients requiring immediate attention are instead managed from the outset by speciality doctors such as surgeons or internal physicians. However, this may lead to barriers through acute and critical care specialities disconnecting from emergency care. Emergency medicine may separate from urgent care, which refers to primary healthcare for less emergent medical issues, but there is obvious overlap, and many emergency physicians work in urgent care settings. Emergency medicine also includes many aspects of acute primary care and shares with family medicine the uniqueness of seeing all patients regardless of age, gender or organ system. The emergency physician workforce also includes many competent physicians who have medical skills from other specialities. Physicians specializing in emergency medicine can enter fellowships to receive credentials in subspecialties such as palliative care, critical care medicine, medical toxicology, wilderness medicine, pediatric emergency medicine, sports medicine, disaster medicine, tactical medicine, ultrasound, pain medicine, pre-hospital emergency medicine, or undersea and hyperbaric medicine. The practice of emergency medicine is often quite different in rural areas where there are far fewer other specialities and healthcare resources. In these areas, family physicians with additional skills in emergency medicine often staff emergency departments. Rural emergency physicians may be the only health care providers in the community and require skills that include primary care and obstetrics. Work patterns Patterns vary by country and region. In the United States, the employment arrangement of emergency physician practices are either private (with a co-operative group of doctors staffing an emergency department under contract), institutional (physicians with or without an independent contractor relationship with the hospital), corporate (physicians with an independent contractor relationship with a third-party staffing company that services multiple emergency departments), or governmental (for example, when working within personal service military services, public health services, veterans' benefit systems or other government agencies). In the United Kingdom, all consultants in emergency medicine work in the National Health Service, and there is little scope for private emergency practice. In other countries like Australia, New Zealand, or Turkey, emergency medicine specialists are almost always salaried employees of government health departments and work in public hospitals, with pockets of employment in private or non-government aeromedical rescue or transport services, as well as some private hospitals with emergency departments; they may be supplemented or backed by non-specialist medical officers, and visiting general practitioners. Rural emergency departments are sometimes run by general practitioners alone.... Discover the Rcem Learning popular books. Find the top 100 most popular Rcem Learning books.
