An analysis of the citation of Clinical Practice Guidelines in China

Objectives: Systematacially analysing the situation of the citations of Clinical Practice Guidelines (CPGs) published in domestic medical journals. Methods: We used “Zhinan” or “Zhiyin” as the term in the title to search WANFANG, VIP and CNKI, and used “Zhinan” in CBM to do a subject heading search until December, 2012. We screened and included the guidelines which met the eligibility criteria, extracted the data of the included studies, and analysed the data with the Excel software. Results: A total of 380 Chinese CPGs were included, among which 172 (45%) guidelines with the citations. The total number of citations was 6255 (citations of a single guideline ranging from 1 to 283), with a mean of 36. Journals were the most important source of citations with 5767(92%). The journal which offered the largest number of citations in Chinese was Chinese Journal of Cardiology, and in English was N Engl J Med. For the study design of citations, 545 studies (8.7%) were systematic reviews or Meta-analysis and 517 studies (8.3%) were RCTs. Average citation number of Cochrane systematic reviews per guideline was 0.4. Conclusions: Guidelines published in domestic journals were low in the proportion of citations reported and with a small average citation number per paper. They mainly cited the studies in the English journals, but the proportion of systematic review citing was low.
