The primary purpose of this document is to provide key information about highly specialised services during 2019/20.

In summary, the information comprises:

• a description of each service
• a list of the expert centres that deliver the service
• NHS England’s total expenditure for each service
• a measure of the activity that each service undertakes (patient numbers fewer than 30 are not included because of the risk of identifying individual patients)
• clinical outcomes from the service
• information about geographical equity of access to the service.

In a small number of cases, some additional information is provided about the service in relation to service innovation, improvement and listening to and acting on patient feedback.
