2021 Journal Impact Factor for Cochrane Database of Systematic Reviews rises to 12.008

This year the Cochrane Database of Systematic Reviews (CDSR) Journal Impact Factor is 12.008; this is an increase on the 2020 Journal Impact Factor which was 9.289. In addition, our (unofficial) CIDG impact factor is 34.275 (40 publications cited 1371 times). This is great news for the CIDG and justifies our strategy set some years ago to concentrate on only high-impact, timely reviews and updates.

The Journal Impact Factor is a tool for ranking, evaluating, and comparing journals and a measure of the frequency with which the 'average article' in a journal has been cited in a particular year. It is published in the Journal Citation Reports (JCR) on an annual basis by Clarivate Analytics.

Some highlights from the CDSR 2021 Journal Citation Report:

  • CDSR is ranked 19th of the 172 journals in the Medicine, General & Internal category
  • CDSR received 92,845 cites in the 2021 Journal Impact Factor period, compared with 81,212 in 2020 
  • The 5-Year Journal Impact Factor is 11.956 compared with 9.871 in 2020

The CIDG editorial base is located at the Liverpool School of Tropical Medicine in Liverpool, UK.  Over 600 authors from some 52 countries contribute to the preparation of the Cochrane Reviews. They are supported by an international team of Editors, each with topic or methodological expertise. The CIDG’s main areas of work are on determination of the effects of interventions on the prevention or treatment infectious diseases of relevance to the United Nations Sustainable Development Goals, particularly malaria, tuberculosis, HIV/AIDS, and neglected tropical diseases.
