On the medical education side, programs to teach evidence-based medicine have been created in medical schools in Canada, the US, the UK, Australia, and other countries. A 2009 study of UK programs found the more than half of UK medical schools offered some training in evidence-based medicine, although there was considerable variation in the methods and content, and EBM teaching was restricted by lack of curriculum time, trained tutors and teaching materials.  Many programs have been developed to help individual physicians gain better access to evidence. For example, Up-to-date was created in the early 1990s.  The Cochrane Center began publishing evidence reviews in 1993.  BMJ Publishing Group launched a 6-monthly periodical in 1995 called Clinical Evidence that provided brief summaries of the current state of evidence about important clinical questions for clinicians.  Since then many other programs have been developed to make evidence more accessible to practitioners.
