The concept of saturation is commonly mentioned in pharmacy research, but there has been recent debate among the applied qualitative research community that challenges the appropriateness of this construct for many qualitative research efforts. This begins by describing the origins of saturation as a grounded theory construct and discusses how saturation is currently being used. Three challenges are discussed related to the use of saturation in pharmacy related to the epistemological, methodological, and practical use of saturation by pharmacy researchers and how they relate to the goals and reporting quality of pharmacy practice research The commentary describes how the concept of information power and established guidance on analysis quality can better justify sample size inform decisions about when to cease further data collection, hopefully increasing the transparency of reporting and supporting rigorous and coherent analyses.
饱和度这一概念在药学研究中经常被提及,但在应用定性研究领域中,最近出现了一场争论,质疑该概念是否适用于许多定性研究工作。本文首先描述了饱和度作为扎根理论构建的起源,并讨论了当前饱和度的使用方式。接着讨论了与药学研究相关的饱和度使用的三个挑战,涉及饱和度在认识论、方法论和实际应用方面的问题,以及它们与药学实践研究的目标和报告质量的关系。本文述评还描述了信息能力的概念和关于分析质量的既定指导原则如何更好地证明样本量决策的合理性,以决定何时停止进一步的数据收集,希望提高报告的透明度,并支持严谨和一致的分析。
