The evaluation of complex medical informatics applications involves not only the information system, but also its impact on the organizational environment in which it is implemented. In instances where these applications cannot be evaluated with traditional experimental methods, computer simulation provides a flexible approach to evaluation. The construction of a computer simulation model involves the development of a model that represents important aspects of the system under evaluation. Once validated, the model can be used to study the effects of variation in system inputs, differences in initial conditions and changes in the structure of the system. Three examples are discussed, namely, a wide-area health care network, physician order entry into a hospital information system, and the use of an information system designed to prevent medical errors that lead to adverse drug events in hospitals.
对复杂医学信息学应用的评估不仅涉及信息系统，还涉及其对实施该系统的组织环境的影响。在这些应用无法用传统实验方法进行评估的情况下，计算机模拟提供了一种灵活的评估方法。构建计算机模拟模型需要开发一个代表被评估系统重要方面的模型。一旦经过验证，该模型可用于研究系统输入变化、初始条件差异以及系统结构变化的影响。文中讨论了三个例子，即广域医疗保健网络、医生向医院信息系统录入医嘱，以及使用旨在预防导致医院不良药物事件的医疗差错的信息系统。
