The complexity of health technology assessment (HTA) has increased, in part because of its evolution through three distinct phases: the machine, the clinical outcomes, and the delivery models. However, the theoretical foundation for the field remains underdeveloped.
It is high time for HTA to bring together aspects of conceptual and theoretical works from other fields to strengthen the foundation of HTA.
Many challenges await the further development of HTA. They can be captured around three research themes: adapting HTA to an evolving analysis object; translating HTA results into policy, management, and practice decisions; and evaluating organizational models of HTA.
Consolidating the scientific basis of HTA is essential if we are to succeed in increasing the relevance of HTA in some of the most challenging health-related decisions that we will make as individuals and societies.
卫生技术评估（HTA）的复杂性有所增加，部分原因在于它经历了三个不同阶段的演变：机器阶段、临床结果阶段和交付模式阶段。然而，该领域的理论基础仍不完善。
现在是HTA将其他领域的概念和理论工作的各个方面整合起来以加强HTA基础的时候了。
HTA的进一步发展面临许多挑战。这些挑战可以围绕三个研究主题来概括：使HTA适应不断演变的分析对象；将HTA结果转化为政策、管理和实践决策；以及评估HTA的组织模式。
如果我们要成功提高HTA在我们作为个人和社会所做出的一些最具挑战性的健康相关决策中的相关性，巩固HTA的科学基础至关重要。
