Clinical Assessment Unit, Chelsea

The Clinical Assessment Unit (CAU) is an acute cancer (oncology) unit in The Royal Marsden's Chelsea hospital.

The unit is for cancer patients who need prompt assessment for troublesome symptoms, either due to their treatment or disease. A specialised team of doctors, nurses and other healthcare professionals carry out thorough assessments and perform various tests and investigations in order to develop a tailored plan of care and treatment.

Our experienced and knowledgeable team aim to provide effective and efficient care in a timely manner. Having a dedicated ‘acute oncology service’ means that many patients can leave the hospital on the same day they are treated. If an overnight stay is required, admission to The Royal Marsden or a nearby hospital or hospice is arranged.

There are eight trolley bed areas and five treatment chairs in the unit. There are designated male and female toilet facilities with disabled access to both.

Day case procedures

Some elective day case procedures are performed on the unit to minimise delays in treatments and assist with diagnoses. These include:

Abdominal drains
Bladder care post-urinary catheter removal
Blood product transfusions
Intravenous infusions
Care before and after interventional radiological guided biopsies / procedures
Bone marrow aspirates and trephines
Lumbar punctures.

Usually day case patients will go home on the same day as their treatment.

Nurses working on CAU have a firm knowledge and understanding of cancer nursing and are expertly skilled in a number of clinical procedures, such as:

Taking blood (phlebotomy)
Inserting a fine tube into a vein (cannulation)
Inserting a tube for urinary drainage (catheterisation)
Giving medications, fluids and various blood products into a vein.
