Clinical Networks are part of NHS England, working across the boundaries of commissioning and provision, as engines for change in the modernised NHS. They are one element of the new system that supports commissioners with their core purpose of quality improvement and ultimately the achievement of outcome ambitions for patients. Clinical Networks sit alongside a system of Operational Delivery Networks and Clinical Senates, supporting innovation and service improvement where a large scale change is required across very complex pathways of care involving many professional groups and organisations.
