<unk>  is a branch of medicine that is practiced in a hospital<unk> ergency department, in the field by<unk> ergency medical service, such as paramedics, and other locations where initial medical treatment of illness takes place.  Just as clinicians operate by immediacy rules under large<unk> ergency systems,<unk> ergency physicians and other allied health care workers in the<unk> ergency department base their practice on a triage system.<unk>  focuses on diagnosis and treatment of acute illnesses and injuries that require immediate medical attention. While not usually providing long-term or continuous care,<unk>  physicians and paramedics still provide care with the aim of improving long-term patient outcome.
Urgent Care Centers are often staffed by physicians, nurses and nurse practitioners who may or may not be formally trained in<unk> . They offer primary care treatment to patients who desire or require immediate care, but who do not reach the acuity that requires care in an<unk> ergency department.<unk>  encompasses a large amount of general medicine but involves virtually all fields of medicine including the surgical sub-specialties.<unk> ergency physicians are tasked with seeing a large number of patients, treating their illnesses and arranging for disposition - either admitting them to the hospital or releasing them after treatment as necessary. The<unk> ergency physician requires a broad field of knowledge and advanced procedural skills often including surgical procedures, trauma resuscitation, advanced cardiac life support and advanced airway management. <unk> ergency physicians ideally have the skills of many specialists - the ability to manage a difficult airway (anesthesia), suture a complex laceration (plastic surgery), reduce (set) a fractured bone or dislocated joint (orthopedic surgery), treat a heart attack (internist), work-up a pregnant patient with vaginal bleeding (Obstetrics and Gynecology), and stop a bad nosebleed (ENT).
