Please use the NHS e-Referral Service (eRS) for all GP referrals into Barts Health, including urgent two week waits.

Information and links to referral forms can be found on the dedicated webpage.

Written and exception referrals 

Some specialist or urgent services may be exempt from Paper Switch Off. Please check our website page on a regular basis for details.  

Urgent cancer referrals 

All cancer two week wait services are available on eRS and must be sent this way.

Urgent care centres, out-of-hours primary care providers, hospital clinicians, dentists and optometrists are advised to use the MS Word version of the Pan-London Suspected Cancer Referral Forms to refer patients with a suspected cancer.  When referring a patient, a copy should also be sent to the patient’s GP.  

Dental referrals 

To help dentists refer to our services, we have set out careful guidelines and special referral forms  which must be read carefully and used appropriately. 

Rules for requesting radiology exams in Millennium have changed

Rules for requesting radiology exams in Millennium have changed

If you refer patients for any diagnostic imaging, you must have the appropriate IRMER training in line with regulations. 

From 1 April 2023, non-medical clinical staff need to have completed their training and had their application approved by the radiology team to continue referring patients for imaging services. This includes people who make referrals to our service from outside Barts Health. This change is being made so that we are compliant with the law.

How can I make referrals?

All authorised staff will be granted automatic access to imaging referrals via CRS.

However, non-medical referrers must be registered with a professional healthcare body and successfully completed training. Access will then be granted on an individual basis by the radiology team when you submit your Non-medical imaging referral application form[docx] 24KB.

Some groups of staff are not covered by legislation to make ionising referrals, including physician associates, medical secretaries and admin staff. Teams will need to ensure that there are registered referrers in place to make these referrals following the formalised change on 1 April.
