Value assessment frameworks have gained prominence recently in the context of U.S. healthcare. Such frameworks set out a series of factors that are considered in funding decisions. The UK's National Institute of Health and Care Excellence (NICE) is an established health technology assessment (HTA) agency. We present a novel application of text analysis that characterizes NICE's Technology Appraisals in the context of the newer assessment frameworks and present the results in a visual way.
A total of 243 documents of NICE's medicines guidance from 2007 to 2016 were analyzed. Text analysis was used to identify a hierarchical set of decision factors considered in the assessments. The frequency of decision factors stated in the documents was determined and their association with terms related to uncertainty. The results were incorporated into visual representations of hierarchical factors.
We identified 125 decision factors, and hierarchically grouped these into eight domains: Clinical Effectiveness, Cost Effectiveness, Condition, Current Practice, Clinical Need, New Treatment, Studies, and Other Factors. Textual analysis showed all domains appeared consistently in the guidance documents. Many factors were commonly associated with terms relating to uncertainty. A series of visual representations was created.
This study reveals the complexity and consistency of NICE's decision-making processes and demonstrates that cost effectiveness is not the only decision-criteria. The study highlights the importance of processes and methodology that can take both quantitative and qualitative information into account. Visualizations can help effectively communicate this complex information during the decision-making process and subsequently to stakeholders.
价值评估框架最近在美国医疗保健领域备受关注。这些框架列出了在资助决策中考虑的一系列因素。英国国家卫生与保健优化研究所(NICE)是一家成熟的卫生技术评估(HTA)机构。我们提出了一种文本分析的新应用,即在较新的评估框架背景下描述 NICE 的技术评估,并以可视化的方式呈现结果。
对 NICE 2007 年至 2016 年的药品指南中的 243 份文件进行了分析。文本分析用于识别评估中考虑的分层决策因素。确定了文件中陈述的决策因素的频率,并确定了它们与不确定性相关术语的关联。结果被纳入分层因素的可视化表示中。
我们确定了 125 个决策因素,并将这些因素按八个领域进行了层次分组:临床效果、成本效果、病情、现行做法、临床需求、新疗法、研究和其他因素。文本分析表明,所有领域在指南文件中始终存在。许多因素通常与与不确定性相关的术语相关联。创建了一系列可视化表示。
本研究揭示了 NICE 决策过程的复杂性和一致性,并表明成本效益并非唯一的决策标准。该研究强调了考虑定量和定性信息的过程和方法的重要性。可视化可以在决策过程中帮助有效地传达这种复杂信息,并随后传达给利益相关者。
