This report sets out a unique approach to the commissioning of specialised paediatric services. It will be of particular interest to those involved in commissioning or delivering these services, but it has broader implications. It provides a clinically agreed system for representing the nature of the relationships between specialised services, and sets out which services need to be delivered from the same location and which do not. This will be of interest to those assessing the configuration of paediatric services and indeed any services that relate to them - both wider children’s services and services to adults.
