Cost-effectiveness analysis (CEA) is a method for choosing between alternative strategies to achieve a specified outcome in an environment of limited resources. This paper discusses the use of CEA in evaluating prevention strategies in industrial settings, using cumulative trauma disorder (CTD) prevention programs as an example. Methodologic issues in designing studies of cost-effectiveness for preventive interventions are discussed. A decision analysis model of a CTD prevention program is described as a means of studying the program's cost-effectiveness. The relationship between CEA and outcomes research, and the strengths and limitations of CEA in evaluating occupational health prevention programs is considered.
成本效益分析（CEA）是一种在资源有限的环境中，在替代策略之间进行选择以实现特定结果的方法。本文以累积性创伤障碍（CTD）预防计划为例，讨论了CEA在评估工业环境中预防策略的应用。文中讨论了设计预防性干预措施成本效益研究中的方法学问题。描述了一个CTD预防计划的决策分析模型，作为研究该计划成本效益的一种手段。文中考虑了CEA与结果研究之间的关系，以及CEA在评估职业健康预防计划中的优势和局限性。
