Exercising for mass casualty incidents is mandated by governing organisations with the aim of maintaining readiness within the healthcare sector for the many challenges these incidents bring. This readiness is delivered through a combination of discussion-based and operation-based exercises that are targeted to the needs of both the individuals delivering care and the needs of the overall system of patient flow and treatment. Although exercising for disaster preparedness is resource intensive, it is the repetitive, iterative nature that allows for wide staff capture and exposure along with continual improvement of plans. Having been recently involved in exercising is also likely to increase the confidence of staff and makes them feel better prepared. Exercising should be tailored to the needs and likely challenges of each healthcare system. A cycle of design, challenge, and redesign should target areas of greatest need and greatest benefit. The conventional advice, when introducing exercising, is to start small and build up over time with repeated exercises that demonstrate increasing response capability. However, some organisations would benefit from an exercise that lays bare shortcomings and acts to galvanise change.

管理组织要求针对大规模伤亡事件进行演习，目的是保持医疗保健部门为应对这些事件带来的许多挑战做好准备。这种准备是通过基于讨论和基于操作的练习的组合来实现的，这些练习针对提供护理的个人的需求以及患者流动和治疗的整体系统的需求。尽管为备灾而进行的演练是资源密集型的，但它是重复性、迭代性的，允许广泛的工作人员捕获和接触，同时不断改进计划。最近参加过锻炼也可能会增加员工的信心，让他们感觉准备得更好。锻炼应根据每个医疗保健系统的需求和可能面临的挑战进行调整。设计、挑战和重新设计的循环应该针对最需要和最大利益的领域。在引入锻炼时，传统的建议是从小处着手，随着时间的推移通过反复锻炼来增强反应能力。然而，一些组织将从暴露缺陷并采取行动激发变革的练习中受益。
