Connecting for Health (part of the NHS in England) has not renewed its contract with BMJ Publishing which made access to Clinical Evidence freely available at the point of use to doctors, CfH has chosen a rival service, Prodigy Knowledge, which is supplied by the vendors of the Prodigy clinical software systems.
Clinical Evidence is a highly “value-added” database of clinical knowledge. According to its own website, “Clinical Evidence summarises the current state of knowledge and uncertainty about the prevention and treatment of clinical conditions, based on thorough searches and appraisal of the literature. It is neither a textbook of medicine nor a set of guidelines. It describes the best available evidence from systematic reviews, RCTs and observational studies where appropriate, and if there is no good evidence it says so.”
Peter Suber has blogged this as an open access issue. It seems to me to be much more a contractual haggle about the perpetual access terms in a national site licence than a typical OA issue.
