The UK Cochrane Centre (UKCC) was established at the end of 1992, by the National Health Service Research and Development Programme and is now part of the National Institute for Health Research. We provide training and support to Cochrane entities and contributors to The Cochrane Collaboration in the UK, Ireland, and some other countries; act as a knowledge broker for Cochrane reviews; and run a programme of methodology research and audit. We are a key link between the Collaboration, Cochrane reviews, and the National Health Service.
