Editorial for issue 4 of 2014, Journal of Evidence Based Medicine

In these final months of 2014, we can look back on both the year and the decade. In the year, The Cochrane Collaboration published its 6000th full Cochrane Review in the Cochrane Database of Systematic Reviews. Less than 20 years since the first issue contained a few dozen reviews, the work of tens of thousands of people around the world has now produced this vast collection of summaries of research for decision makers in health and social care. Much work remains to be done, of course, and the Cochrane itself is striving to improve its methods and its outputs. For example, in this issue of the Journal, we publish the findings of a study by Soumyadeep Bhaumik and Rebecca Joyce Mathew of the South Asian Cochrane Network and Centre of the 788 editors of Cochrane Review Groups and the Cochrane Editorial Unit. They conclude that the representation of women editors is better than in the editorial boards of medical journals more generally, but that there is still scope for improvement to ensure better gender diversity. People in the South Asian Cochrane Network and Centre were pivotal in the development of Evidence Aid, and nearly 10 years on from the Indian Ocean Tsunami which led to its establishment, they hosted the third Evidence Aid Conference, shortly before the Cochrane Colloquium in September. Here, and in the next issue, we are pleased to publish articles from the presentations at that Symposium and this month’s education article provides a plain language summary of the background to Evidence Aid. We also continue with our mixture of articles from China and internationally, covering both studies of the preparation and use of evidence for health care, and examples of that evidence. You will find systematic reviews of the relationship between polymorphisms in the eNOS gene and cancer risk, and of the effects of high-intensity focused ultrasound for the treatment of pancreatic cancer. We are also pleased to include an evaluation of organizational support for the use of online information resources in nursing care and a study of a training system to reduce preanalytical errors in laboratories.
