Acute Assessment Unit (AAU)

What we do

The Acute Assessment Unit opened in 2010 to provide rapid assessment, diagnosis and treatment of patients with urgent medical conditions. It also enables patients with acute conditions to be closely observed by an expert multiprofessional team, reducing the pressure on A&E. More than 40% of patients will complete their care within the AAU, thus maintaining continuity of care for many, and promoting specialty-based care for those requiring longer hospital admissions. Patients admitted to the unit will be seen by a consultant within 12 hours—the majority much sooner.

The unit operates 24/7 and accepts patients from A&E and consultant clinics. The 54-bed unit incorporates 36 inpatient beds, 9 acute enhanced care beds and a 10-trolley bed assessment area.

The AAU is staffed by a dedicated team of doctors, nurses, therapists, pharmacists and other allied health professionals so patients can access the most appropriate treatment as quickly as possible.

The unit also facilitates pre-registration training for nursing and medical students.

Visiting times

Daily from 2–8pm at the discretion of the senior nurses. Please note: Children under the age of 12 are not permitted on the AAU.

A great place to work means a great place to be treated
