The Art & Science section of Nursing Standard this week is devoted to encouraging nurses to use evidence in their practice. As well as publishing some of the papers from the recent Evidence-Based Nursing conference in London, this report is based on the editorial which appeared in the pilot issue of Evidence-Based Nursing, a new journal jointly published by the BMJ Publishing Group and the RCN Publishing Company. It highlights the importance of using evidence in practice and explores the role of the new journal, which will be launched in November 1997, in helping nurses to achieve this aim.
