Non-core members of the group may be drawn upon for specialist advice and expertise required to deliver the key objectives of the CRG work programme.


A key part of the CRG’s work is the delivery of the ‘products’ of commissioning. These are the tools used by commissioning teams to contract services on an annual basis.

Service specifications

Service specifications are important in clearly defining the standards of care expected from organisations funded by NHS England to provide specialised care. The specifications have been developed by specialised clinicians, commissioners, expert patients and public health representatives to describe both core and developmental service standards. Core standards are those that all funded providers should be able to demonstrate, with developmental standards being those which may require further changes in practice over time to provide excellence in the field.

The following service specifications fall within the scope of this CRG:

Adult Critical Care Planning Programme

The Adult Critical Care Planning Programme supports Adult Critical Care to restore and strengthen services, preparing for the short-term needs, as well as the medium to long term needs of the population. The programme is developing a series of tools and guidance for commissioners, networks and providers to use to plan and deliver services across their footprints.
