An acute medical unit (AMU) is a short-stay department in some British, Australian and New Zealand hospitals that may be linked to the emergency department, but functions as a separate department. [1] The AMU acts as a gateway between a patient's general practitioner, the emergency department, and the wards of the hospital. The AMU helps the emergency department produce a healthy turnaround for patients, helping with the four-hour waiting rule in the United Kingdom. An AMU is usually made up of several bays and has a small number of side-rooms and treatment rooms. They are fully equipped with emergency medical treatment facilities including defibrillators and resuscitation equipment.
From the emergency department, patients can be moved to AMU where they will undergo further tests and stabilisation before they are transferred to the relevant ward or sent home. Also, patients can be admitted straight to AMU from their general practitioner if he or she believes the patient needs hospital treatment. A patient's stay in the unit is limited, usually no more than 48 hours.
The AMU deals with admissions only, patients will never be transferred from a ward to the AMU. Surgical procedures are not carried out in the unit either; these are referred on to the relevant theatre such as cardiothoracics and general surgery.
Senior staff in an AMU typically include a consultant in acute medicine, general medicine, emergency medicine, or critical care. Often a registrar in general medicine, and a ward sister or a charge nurse have roles in the unit. A number of staff nurses work alongside the senior staff to provide care to patients in the unit.
Although AMU has its own staff trained to deal with patients and provide care, members of staff from other departments in the hospital are needed in AMU to assess patients and provide further diagnosis. Typical examples of staff who may be needed in AMU are general surgeons, cardiothoracic surgeons, cardiologists, and a psychiatric liaison nurse.
The name "acute medical unit" is recommended by the Royal College of Physicians in its 2007 acute medicine report. [2] Despite this, many hospitals use different names for the department. Common names for this department are:
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.
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.

Acute medicine is distinct from the broader field of emergency medicine, which is concerned with the management of all people attending the emergency department, not just those with internal medicine diagnoses.
