Realist reviews offer a rigorous method to analyze heterogeneous data emerging from multiple disciplines as a means to develop new concepts, understand the relationships between them, and identify the evidentiary base underpinning them. However, emerging synthesis methods such as the Realist Review are not well operationalized and may be difficult for the novice researcher to grasp. The objective of this paper is to describe the development of an analytic process to organize and synthesize data from a realist review.
Clinical practice guidelines have had an inconsistent and modest impact on clinical practice, which may in part be due to limitations in their design. This study illustrates the development of a transparent method for organizing and analyzing a complex data set informed by a Realist Review on guideline implementability to better understand the characteristics of guidelines that affect their uptake in practice (e.g., clarity, format). The data organization method consisted of 4 levels of refinement: 1) extraction and 2) organization of data; 3) creation of a conceptual map of guideline implementability; and 4) the development of a codebook of definitions.
This new method is comprised of four steps: data extraction, data organization, development of a conceptual map, and operationalization vis-a-vis a codebook. Applying this method, we extracted 1736 guideline attributes from 278 articles into a consensus-based set of categories, and collapsed them into 5 core conceptual domains for our guideline implementability map: Language, Format, Rigor of development, Feasibility, Decision-making.
This study advances analysis methods by offering a systematic approach to analyzing complex data sets where the goals are to condense, organize and identify relationships.
现实主义综述提供了一种严谨的方法,可用于分析来自多个学科的异质数据,以开发新概念、理解它们之间的关系,并确定支撑它们的证据基础。然而,新兴的综合方法(如现实主义综述)尚未得到很好的实施,可能对新手研究人员来说难以理解。本文旨在描述一种分析过程的开发,以组织和综合现实主义综述中的数据。
临床实践指南对临床实践的影响一直不一致且适度,这可能部分归因于其设计的局限性。本研究说明了一种透明方法的开发,用于组织和分析一个复杂的数据集,该数据集受关于指南可实施性的现实主义综述的启发,以更好地理解影响指南在实践中采用的特征(例如,清晰度、格式)。数据组织方法包括 4 个细化级别:1)提取和 2)组织数据;3)创建指南可实施性的概念图;4)开发定义代码本。
这种新方法由四个步骤组成:数据提取、数据组织、概念图的开发以及代码本的操作化。应用这种方法,我们从 278 篇文章中提取了 1736 条指南属性,将其归入一组基于共识的类别,并将其合并为 5 个核心概念领域,用于我们的指南可实施性图:语言、格式、开发严谨性、可行性、决策。
本研究通过提供一种系统的方法来分析目标是浓缩、组织和识别关系的复杂数据集,推进了分析方法。
