Work Domain Analysis (WDA), the foundational phase in the Cognitive Work Analysis Framework (CWA), provides a platform for understanding and designing complex systems. Though it has been used extensively, there are few applications in healthcare, and model validation for different contexts is not always undertaken. The current study aimed to validate an Emergency Department (ED) WDA across three metropolitan hospitals that differ in the type and nature of services they provide, including the ED in which the original ED WDA was developed. A facilitated workshop was conducted at the first ED and interviews at two subsequent EDs to refine and validate the ED WDA. ED subject matter experts (SMEs) including nurses, doctors, administration, and allied health personnel provided feedback on the model. SME feedback resulted in modifications to the original ED WDA model including combining nodes to reduce duplication and amending five labels for clarity. The resulting WDA provides a valid representation of the EDs found in metropolitan districts within an Australian state and can be used by roles such as frontline ED clinicians, hospital managers, and policy developers to facilitate the design, testing, and sharing of solutions to local and shared problems. The findings also demonstrate the importance of validating WDA models across different contexts.

工作领域分析 (WDA) 是认知工作分析框架 (CWA) 的基础阶段，为理解和设计复杂系统提供了一个平台。尽管它已被广泛使用，但在医疗保健领域的应用很少，并且并不总是针对不同环境进行模型验证。当前的研究旨在验证三家大城市医院的急诊科 (ED) WDA，这三家医院提供的服务类型和性质不同，包括开发原始 ED WDA 的 ED。在第一次 ED 中举办了一次研讨会，并在随后的两次 ED 中进行了访谈，以完善和验证 ED WDA。包括护士、医生、行政人员和专职医疗人员在内的 ED 主题专家 (SME) 提供了对该模型的反馈。SME 的反馈导致对原始 ED WDA 模型的修改，包括组合节点以减少重复并修改五个标签以使其清晰。由此产生的 WDA 提供了澳大利亚州内大都市区的 ED 的有效表示，可供一线 ED 临床医生、医院管理人员和政策制定者等角色使用，以促进解决方案的设计、测试和共享，以供当地和社区使用。共同的问题。研究结果还证明了在不同背景下验证 WDA 模型的重要性。
