Event-based surveillance (EBS) systems have been implemented globally to support early warning surveillance across human, animal, and environmental health in diverse settings, including at the community level, within health facilities, at border points of entry, and through media monitoring of internet-based sources. EBS systems should be evaluated periodically to ensure that they meet the objectives related to the early detection of health threats and to identify areas for improvement in the quality, efficiency, and usefulness of the systems. However, to date, there has been no comprehensive framework to guide the monitoring and evaluation of EBS systems; this absence of standardisation has hindered progress in the field. The Africa Centres for Disease Control and Prevention and US Centers for Disease Control and Prevention have collaborated to develop an EBS monitoring and evaluation indicator framework, adaptable to specific country contexts, that uses measures relating to input, activity, output, outcome, and impact to map the processes and expected results of EBS systems. Through the implementation and continued refinement of these indicators, countries can ensure the early detection of health threats and improve their ability to measure and describe the impacts of EBS systems, thus filling the current evidence gap regarding their effectiveness.

用于监测和评估基于事件的监测系统的指标框架

基于事件的监测（EBS）系统已在全球范围内实施，以支持不同环境下人类、动物和环境健康的早期预警监测，包括在社区层面、卫生设施内、边境入境点以及通过媒体监测基于互联网的资源。应定期评估 EBS 系统，以确保它们满足与早期检测健康威胁相关的目标，并确定系统质量、效率和实用性方面需要改进的领域。然而，迄今为止，还没有一个全面的框架来指导EBS系统的监测和评估；标准化的缺乏阻碍了该领域的进展。非洲疾病控制和预防中心和美国疾病控制和预防中心合作开发了一个 EBS 监测和评估指标框架，该框架适合具体国家的具体情况，使用与投入、活动、产出、结果和影响相关的衡量标准绘制 EBS 系统的流程和预期结果。通过实施和不断完善这些指标，各国可以确保及早发现健康威胁，并提高衡量和描述 EBS 系统影响的能力，从而填补当前有关其有效性的证据空白。
