诊断技术评估方法及应用研究

诊断技术评估有助于充分了解新技术价值，进一步优化临床资源配置。在梳理层次分析和决策理论、逐步评估理论、多准则决策分析理论、检测-治疗价值评估理论四大主要诊断技术评估方法的基础上，以两种急诊肝性脑病血氨诊断方法的评估为例，阐述了检测-治疗价值评估理论模型的应用价值。建议研究者基于具体问题选择适合的评估模型，政策决策者制定诊断产品的HTA指南，助推我国诊断技术HTA的标准化发展。

Method and Application of Diagnostic Technology Assessment

Diagnostic technology assessment can help fully understand the value of new technologies and further optimize the allocation of clinical resources. Based on the four main HTA methods of hierarchical analysis and decision theory, stepwise evaluation theory, multi-criteria decision analysis theory, test and treatment value assessment theory, the evaluation of two diagnostic methods of blood ammonia in emergency hepatic encephalopathy was taken as an example, it expounded the application value of the test and treatment value assessment theoretic model. It was suggested that researchers chose appropriate assessment models based on specific problems, and policy makers formulated HTA guidelines for diagnostic products to promote the standardized development of diagnostic technology HTA in China.
