Cochrane, a global independent network of researchers, professionals, patients, carers and people interested in health, has announced that the Impact Factor of Cochrane Database of Systematic Reviews (CDSR) is now 6.124. According to 2016 Journal Citation Report (JCR), released by Clarivate Analytics (formerly Thomson ISI), this is a slight increase on the 2015 impact factor, which was 6.103.
The CDSR impact factor is calculated by taking the total number of citations in a given year to all Cochrane Reviews published in the past 2 years, and dividing that number by the total number of Reviews published in the past 2 years. It is a useful metric for measuring the strength of a journal by how often its publications are cited in scholarly articles.
Some highlights of the CDSR 2016 Impact Factor include: the CDSR is ranked 14 of the 154 journals in the Medicine, General & Internal category; the CDSR received 57,740 cites in the 2016 Impact Factor period, compared with 47,899 for the 2015 Impact Factor calculation; the total number of times the CDSR was cited increased from 47,899 in 2015 to 57,740 in 2015 meaning the CDSR received the 5th highest number of citations in its category; and the 5-Year Impact Factor is 7.018.
The main Impact Factor report and the CRG reports will be delivered after the JCR is updated in September. This is because, as has happened in previous years, Clarivate was unable to accurately index Cochrane Reviews for this Impact Factor window; Wiley and Cochrane are following-up with Clarivate regarding the calculation of the 2016 impact factor.
