Impact Factor

Each year in June, Clarivate Analytics publish the impact factors of all journals indexed in the Journal Citation Report. The Cochrane Database of Systematic Reviews (CDSR) impact factor describes the ratio of the number of Cochrane Reviews published, for example, during 2010 and 2011 to the number of citations these reviews received in 2012. The CDSR received its first impact factor in 2007.

Latest Impact Factor report


The Cochrane Database of Systematic Reviews (CDSR) 2017 impact factor is 6.754, an increase on the previous year.

The 2016 CRG Impact Factor for the Pain, Palliative and Supportive Care Group is 4.139 (79 publications cited 327 times). A review published by PaPaS in 2014 or 2015 was cited, on average, 4.139 times in 2016.


Previous Impact Factor reports


The 2016 Journal Citation Report (JCR) has just been released by
Clarivate Analytics (formerly Thomson ISI), and we are delighted to announce that Cochrane Database of Systematic Reviews (CDSR) Impact Factor is now 6.124.

This is an 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.

·         The 5-Year Impact Factor is 7.018.

We expect that the CDSR impact factor will be revised when the JCR is updated in September 2017.
