背景：虽然对大数据集的二级数据分析可能会减少执行重大创新工作所需的后勤和财务障碍，但此类研究需要数据处理和统计技术方面的专门技能，以及对所使用的数据源的透彻和详细的了解。目的：概述几种常见的二级数据类型，重点介绍这些数据的优点、缺点和如何将这些数据用于卫生服务研究的实例。结果：二级数据包括一个广泛且不同种类的类别。本审查涵盖了几大类此类数据，并举例说明了它们的使用情况，并讨论了它们的优点和缺点。来源包括行政数据、基于索赔的数据集、电子健康记录健康调查、患者或疾病登记、质量改进举措以及现有试验的数据。将不同类型的数据联系起来，可以扩大可使用二次数据分析回答的问题的范围。结合最新的泌尿外科文献中的例子，讨论了每种类型的数据集的具体优点和缺点。结论：应该根据具体的研究问题以及可用的研究资源和专业知识来选择合适的数据源。关于使用哪些数据的适当决策是使用二次数据进行有效、高影响研究的基础。(C)2017 Elsevier Inc.保留所有权利。
Background: Though secondary data analyses of large datasets may reduce logistical and financial barriers required to perform significant and innovative work, such research requires specialized skills in data handling and statistical techniques as well as thorough and detailed knowledge of the data sources being used.Objectives: To provide an overview of several common types of secondary data, focusing on strengths, weaknesses and examples of how these data may be used for health services research.Results: Secondary data comprise a broad and heterogeneous category. This review covers several large categories of such data with examples of their use and discussions about their strengths and weaknesses. Sources include administrative data, claims-based datasets, electronic health records health surveys, patient or disease or both registries, quality improvement initiatives, as well as data from existing trials. Linkages of different types of data may expand the scope of questions answerable using secondary data analysis. Specific strengths and weaknesses of each type of dataset are discussed along with examples from the recent urologic literature.Conclusions: Choice of the appropriate data source should be tailored to the specific research question as well as the research resources and expertise available. Appropriate decisions about which data to use are the foundation for valid, high-impact research using secondary data. (C) 2017 Elsevier Inc. All rights reserved.
