早期预警系统涉及例行监测和在专门设计的图表上记录生命体征或临床观察结果，并附有相关的逐步升级协议。符合异常生理参数的标准会触发颜色编码或加权评分系统，旨在指导监测频率、临床审查的需要和紧迫性。当红色区域记录到一个或多个异常观察结果或琥珀色区域记录到两个或多个轻度异常参数时，颜色编码系统触发临床反应。产妇专用预警系统对住院妇女进行监测的原则是直观的。然而，广泛使用和政策支持，包括在秘密调查后和国家卫生服务诉讼管理局提出的建议，目前没有强有力的证据基础。需要进行研究，以开发预测模型，并在一般产妇人群中验证基于证据的产妇专用预警系统。
Early warning systems involve the routine monitoring and recording of vital signs or clinical observations on specifically designed charts with linked escalation protocols. Meeting criteria for abnormal physiological parameters triggers a color‐coded or weighted scoring system aimed to guide the frequency of monitoring, need for, and urgency of clinical review. Color‐coded systems trigger a clinical response when one or more abnormal observation is recorded in the red zone or two or more mildly abnormal parameters in the amber zone. The principle of maternity‐specific early warning systems to structure surveillance for hospitalized women is intuitive. The widespread use and policy support, including recommendations following confidential enquiries and from the National Health Service Litigation Authority, is not, however, currently backed up by a strong evidence base. Research is required to develop predictive models and validate evidence‐based maternity‐specific early warning systems in the general maternity population.
