Abstract
Background: Distance from research to practice always exists. The dissemination and utilization of systematic reviews/ meta-analyses (S/Ms) as the best evidence is increasingly concerned. China, as the largest developing country with more than 1.3 billion people, inwhere it is very important to push the local production and utilization of S/Ms for the improving of health decision making, research, and clinical practice. Objective: To learn and analyze the citation of S/Ms published in Chinese journals for accelerating the translation of them. Methods: We searched the Chinese Medical Citation Index (CMCI) database (up to Feb. 2010) using the term ‘‘systematic review’’ and ‘‘meta-analysis’’ to identify S/M. SPSS 15.0 software was used for statistical analysis. Results: 2810 records were retrieved, and finally 2294 S/Ms were included. They were published in 610 journals from 1994 to 2009. The median publishing number of each journal was 2 (Min-Max: 1–272). The total citation frequency for these papers was 2863, with an average number 1.25 (Min-Max: 0–57) for every one. 1420 S/Ms (61.9%) have never been cited. The average citation frequency of each Systematic review was lower than that of each meta-analysis (Z = −2.316, P = 0.021). There had no statistical difference of the average citation frequency of each S/M published in ‘‘evidence-based medicine’’ titled journals and other journals (Z = −1.661, P = 0.097). No relationship was found between the citation frequency of a paper and its reference’s number (r = 0.040, P = 0.117). A descent tendency for the citation frequency was found from 2004 (Figure). Conclusions: Most of the S/Ms published in Chinese journals are not cited or low cited. The condition is becoming worse. This reflects that the utilization level of S/Ms is still low in China because of miscellaneous reasons. It is necessary to conduct more translation research and practice to shorten the distance from research to practice.
