Ambulatory Assessment Unit (AAU)

The Ambulatory Assessment Unit (sometimes called AAU) offers patients the medical assessment, treatment and care they require without the need to be admitted to hospital.

AAU is a 'day unit'. The average time patients stay here is five to seven hours, but patients who need more complicated treatments may stay longer. Please bear this in mind when making arrangements.

Please come to AAU as early as you can. If you arrive after 7.00pm on weekdays or after 5.00pm at weekends, we may need to send you to another area for treatment, and your treatment may be delayed as a result.

When you arrive, please speak to the receptionist, who will confirm your details and explain what happens next.

For further information about AAU please contact us.
