目标：提供经济评价中建模的替代方法的概述，并强调应采用每种替代建模技术的情况。METHODS：回顾医疗保健干预措施经济评价中建模的可用方法，并对已发表的研究实例进行讨论，以指导在不同情况下选择适当的方法。卫生保健经济评价中使用的主要建模方法是决策树、马尔可夫模型和个体抽样模型。这些方法假设模型中的个体是独立的。在个人之间的相互作用是很重要的，其他方法，如离散事件模拟或系统dynamics是preferab.CONCLUSIONS：该文件突出了选择建模方法时要回答的关键问题：可以被模拟的个人在模型中被视为独立的？这个问题通常没有被分析师认识到，但对于经济评估中模型的适当应用至关重要。
OBJECTIVES: To provide an overview of alternative approaches to modelling in economic evaluation, and to highlight situations where each of the alternative modelling techniques should be employed.METHODS: A review of the available approaches to modelling in the economic evaluation of health care interventions with a leading discussion of examples of published studies leading to guidance in the selection of an appropriate approach in different circumstances.RESULTS: The main approaches to modelling used in economic evaluations in health care are decision trees, Markov models and individual sampling models. These methods assume independence of individuals within the model. Where interaction between individuals is important, other methods such as discrete-event simulation or system dynamics are preferable.CONCLUSIONS: The paper highlights the crucial question to be answered when selecting the approach to modelling: can the individuals being simulated in the model be regarded as independent? This issue is very commonly not recognised by analysts but is fundamental to the appropriate application of modelling in economic evaluation.
