The NHS Clinical Knowledge Summaries (formerly PRODIGY) are a reliable source of evidence-based information and practical 'know how' about the common conditions managed in primary care.
CKS is no longer commissioned by the National Institute for Health and Clinical Excellence (NICE). NICE remains committed to providing a replacement service for CKS and is currently reviewing its options. In the meantime, CKS content will remain browsable on this site and also searchable on the NHS Evidence website where a wide range of additional information resources may be found, but please note that from March 2011 the content of CKS is no longer being maintained.
