<unk>  is the medical speciality concerned with the care of illnesses or injuries requiring immediate medical attention.<unk> ergency physicians (often called “ER doctors” in the United States) continuously learn to care for unscheduled and undifferentiated patients of all ages. As first-line providers, in coordination with<unk> ergency 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.<unk> ergency physicians generally practise in hospital<unk> ergency departments, pre-hospital settings via<unk> ergency medical services, and intensive care units. Still, they may also work in primary care settings such as urgent care clinics. Sub-specializations of<unk>  include; disaster<unk> , medical toxicology, point-of-care ultrasonography, critical care<unk> ,<unk> ergency medical services, hyperbaric<unk> , sports<unk> , palliative care, or aerospace<unk> . Various models for<unk>  exist internationally. In countries following the Anglo-American model,<unk>  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<unk> ergency medical care is instead provided directly by anesthesiologists (for critical resuscitation), surgeons, specialists in internal<unk> , paediatricians, cardiologists or neurologists as appropriate.<unk>  is still evolving in developing countries, and international<unk>  programs offer hope of improving primary<unk> ergency care where resources are limited..
