Pre-operative assessment clinic

The pre-operative assessment clinic is a nurse-led clinic and plays an important part in the preparation for your surgery. It includes an assessment of your general health and fitness before surgery by carrying out various tests and investigations. If you have more complex medical issues you may be seen in an clinic led by an anaesthetic consultant.

A pre-operative assessment appointment can take up to two hours. While waiting, refreshments are available.

Inpatient admissions and discharge

APU also accommodates patients coming into the hospital for an inpatient stay.

Before being taken to your ward you will be asked to wait in the lounge area until your bed becomes available. During this time, a nurse will check your demographic details, carry out any tests that may be required (for example, blood tests or height and weight checks) and perform cannulation if required. APU staff will keep you informed about the ward you will be going to and give you an approximate waiting time.

We ask inpatients to leave by 10am on the day they are discharged from hospital. If you have to wait at the hospital for transport or to collect medications, you may be asked to wait in the APU.

APU staff

Nursing staff in the APU are all experienced and specialised in pre-assessment, and are trained in skills such as phlebotomy, cannulation, ECG monitoring and physical examination. They work closely with consultant anaesthetists, assisting with cardiopulmonary and respiratory assessment and cardiopulmonary exercise testing, and with the multidisciplinary team to facilitate a holistic assessment of each patient.

The on-call clinical site practitioner is based on the APU 24 hours a day, working closely with the nurses on the wards and medical colleagues for support. This involves coordinating admissions, telephone triage to ensure patients are admitted accordingly to clinical need and acuity, and assisting patients with queries out of hours.
