To evaluate the production and utilization of Cochrane systematic reviews (CSRs) and to analyze its influential factors, so as to improve the capacity of translating CSRs into practice.
All CSRs and protocols were retrieved from the Cochrane Library (Issue 2, 2011) and citation data were retrieved from SCI database. Citation analysis was used to analyze the situation of CSRs production and utilization.
CSR publication had grown from an annual average of 32 to 718 documents. Only one developing country was among the ten countries with the largest amount of publications. High-income countries accounted for 83% of CSR publications and 90.8% of cited counts. A total 34.7% of CSRs had a cited count of 0, whereas only 0.9% had been cited more than 50 times. Highly cited CSRs were published in England, Australia, Canada, USA and other high-income countries. The countries with a Cochrane center or a Cochrane methodology group had a greater capability of CSRs production and citing than others. The CSRs addressing the topics of diseases were more than those targeted at public health issues. There was a big gap in citations of different interventions even on the same topic.
The capability of CSR production and utilization grew rapidly, but varied among countries and institutions, which was affected by several factors such as the capability of research, resources and the applicability of evidence. It is important to improve evidence translation through educating, training and prioritizing the problems based on real demands of end users.
评价 Cochrane 系统评价(CSR)的产出和利用情况,并分析其影响因素,以提高将 CSR 转化为实践的能力。
从 Cochrane 图书馆(2011 年第 2 期)中检索所有 CSR 和方案,并从 SCI 数据库中检索引用数据。引文分析用于分析 CSR 产出和利用情况。
CSR 的发表量从年均 32 篇增长至 718 篇。在发表量最多的十个国家中,只有一个发展中国家。高收入国家占 CSR 发表量的 83%,引用量的 90.8%。有 34.7%的 CSR 没有被引用,而只有 0.9%的 CSR 被引用超过 50 次。高被引 CSR 发表于英国、澳大利亚、加拿大、美国和其他高收入国家。有 Cochrane 中心或 Cochrane 方法学组的国家比其他国家具有更强的 CSR 产出和引用能力。针对疾病主题的 CSR 多于针对公共卫生问题的 CSR。即使针对同一主题,不同干预措施的引用量也存在很大差距。
CSR 的产出和利用能力增长迅速,但在国家和机构之间存在差异,这受到研究能力、资源和证据适用性等多种因素的影响。通过教育、培训和根据最终用户的实际需求确定优先级来提高证据转化的重要性。
