Qualitative secondary analysis (QSA) is the use of qualitative data that was collected by someone else or was collected to answer a different research question. Secondary analysis of qualitative data provides an opportunity to maximize data utility, particularly with difficult-to-reach patient populations. However, qualitative secondary analysis methods require careful consideration and explicit description to best understand, contextualize, and evaluate the research results. In this article, we describe methodologic considerations using a case exemplar to illustrate challenges specific to qualitative secondary analysis and strategies to overcome them.
定性二次分析（QSA）是指使用其他人收集或为回答不同研究问题而收集的定性数据。对定性数据进行二次分析提供了最大化数据效用的机会，特别是对于难以接触到的患者群体。然而，定性二次分析方法需要仔细考虑和明确描述，以最好地理解、背景化和评估研究结果。在本文中，我们使用案例示例描述了方法学上的考虑因素，以说明定性二次分析特有的挑战和克服这些挑战的策略。
