Find out how to refer patients to our accident and emergency departments.


If a patient has been referred as an emergency case by a GP or another hospital to a particular team within the Trust, the patient will still have to register at A&E first. Although the specialty team will be expecting your patient, they may not be able to see them immediately.

If one of your patients has been seen in our A&E we will send you a letter with details of the outcomes and any treatment they received. The patient will also be given a copy of this letter before they leave. Our A&E aims to complete the discharge letter within four hours of the patient’s discharge. The letter will be sent electronically to your practice; however, if the patient does not remember their GP's details this letter will not be sent.
