We are delighted to have this further evidence that <em>BMJ Open<\/em> is considered a journal of credible, valued research.<\/span><\/p>\n<p><b><span style=\"color: #000000\"><span style=\"font-size: medium\"><span style=\"font-family: Calibri\">Does a journal\u2019s impact factor matter?<\/span><\/span><\/span><\/b><\/p>\n<p><span style=\"font-family: Calibri;color: #000000;font-size: medium\">In short \u2013 yes. When we surveyed our authors earlier this year, we asked what improvements we could make to <em>BMJ Open<\/em>. By far the most frequent response was: get an impact factor. The impact factor is over-interpreted, misinterpreted and almost certainly too influential. For as long as it remains important to authors, though, it will remain something journals must promote.<\/span><\/p>\n<p><span style=\"font-family: Calibri;color: #000000;font-size: medium\">The question of whether a journal\u2019s impact factor <em>should<\/em> matter, and how much,\u00a0has been discussed for years. The San Francisco Declaration on Research Assessment (or <a href=\"http:\/\/am.ascb.org\/dora\/\">DORA<\/a>) highlights some of the issues. <\/span><\/p>\n<p><span style=\"font-family: Calibri;color: #000000;font-size: medium\">Unlike many journals, <em>BMJ Open<\/em> doesn\u2019t attempt to select articles on the strength of their likely citation count. So we&#8217;ll never have the highest in our field, and you won&#8217;t find us worrying about that.<\/span><\/p>\n<p><span style=\"color: #000000\"><span style=\"font-size: medium\"><span style=\"font-family: Calibri\">In the future our impact factor may go up or it may go down. Our influence over this will go no further than our continued efforts to ensure <em>BMJ Open<\/em> publishes thoroughly peer-reviewed open access research and serving all our authors as best we can, so we can build on our reputation as a reliable publishing choice for researchers. \u00a0<\/span><\/span><\/span><\/p>\n<p><b><span style=\"color: #000000\"><span style=\"font-size: medium\"><span style=\"font-family: Calibri\">Article-level impact<\/span><\/span><\/span><\/b><\/p>\n<p><span style=\"font-family: Calibri;color: #000000;font-size: medium\">The impact factor is an aggregate measure of <em>BMJ Open<\/em>\u2019s articles and so says nothing about any individual paper. This is why we also publish article-level metrics. Alongside every paper we publish you can see its abstract, HTML and PDF views, and citations to the article from elsewhere on the HighWire publishing platform. <\/span><\/p>\n<p><span style=\"font-family: Calibri;color: #000000;font-size: medium\">Such so-called \u2018altmetrics\u2019 are increasingly popular. There\u2019s a wealth of information about these available, and the <\/span><a href=\"https:\/\/blogs.bmj.com\/bmj-journals-development-blog\/\"><span style=\"font-family: Calibri;font-size: medium\">BMJ Web Development Blog<\/span><\/a><span style=\"font-family: Calibri;color: #000000;font-size: medium\"> is a great place to find out more and keep up to date on these. <\/span><\/p>\n<p><span style=\"color: #000000\"><span style=\"font-size: medium\"><span style=\"font-family: Calibri\">It is important to remember that research impact extends well beyond an article\u2019s citation rate. This is especially so in clinical research where impact on public health and clinical care cannot be captured by bibliographic measures.\u00a0 <\/span><\/span><\/span><\/p>\n<p><b><span style=\"color: #000000\"><span style=\"font-size: medium\"><span style=\"font-family: Calibri\">What is the impact factor? <\/span><\/span><\/span><\/b><\/p>\n<p><span style=\"font-family: Calibri;color: #000000;font-size: medium\">The impact factor is a journal-level citation metric. It is usually calculated over three years, by adding the number of articles a journal publishes in years 1 and 2, and seeing how often, on average, these articles were cited in year 3. As <em>BMJ Open<\/em> only has two years\u2019 worth of citation information, our impact factor was calculated using the number of articles we published in 2011 (which Thomson Reuters calculated as\u00a0 151) and the number of times they were cited in 2012 (239). 239\/151 = 1.583<\/span><\/p>\n<p><b><span style=\"color: #000000\"><span style=\"font-size: medium\"><span style=\"font-family: Calibri\">Most-cited from 2011<\/span><\/span><\/span><\/b><\/p>\n<p><span style=\"font-family: Calibri;color: #000000;font-size: medium\">The following are the papers we published in 2011 with the most citations in the Thomson Reuters Web of Science in 2012:<\/span><\/p>\n<p><span style=\"color: #000000\"><span style=\"font-size: medium\"><span style=\"font-family: Calibri\">Armstrong PK, Dowse GK, Effler PV,\u00a0<em>et al<\/em>.
