摘要
现有数据的二次分析已成为提升卫生研究机构整体效率的一种日益流行的方法。该工作取决于政府、资助机构以及研究者,取决于他们能不能让没有参与原始研究、没有参与创建和维护登记系统的其他合格研究人员获得原始研究数据或登记系统的数据。二次分析的好处是显而易见的,但面临的障碍很多。因此提高这些数据可获得性的工作进展缓慢,在低收入和中等收入国家尤为如此。本文介绍了现有数据二次分析的基本原理和概念,描述了若干个可公开获得的数据库,为现有数据的二次分析提供一般准则,并讨论了现有数据分析的优势和不足。
The secondary analysis of existing data has become an increasingly popular method of enhancing the overall efficiency of the health research enterprise. But this effort depends on governments, funding agencies, and researchers making the data collected in primary research studies and in health-related registry systems available to qualified researchers who were not involved in the original research or in the creation and maintenance of the registry systems. The benefits of doing this are clear but the barriers are many, so the effort of increasing access to such material has been slow, particularly in low- and middle- income countries. This article introduces the rationale and concept of the secondary analysis of existing data, describes several sources of publicly available datasets, provides general guidelines for conducting secondary analyses of existing data, and discusses the advantages and disadvantages of analyzing existing data.
