In this paper, an adaptation of the system-theoretic process analysis (STPA) approach to a sociotechnical system of monitoring and tracking diabetes mellitus (DM) is proposed. Several human controllers such as the patient, physicians, other healthcare providers, and people in the social environment were considered in the hierarchical safety control structure. During the identification of the causal factors (causal scenarios) for the unsafe control actions of the human controllers, the three-phase approach proposed by France (2017) as well as the interaction problems between the subsystems in the hierarchical safety control structure were considered, and the implementation of the basic safety design procedure was included in the methodology for the improvement of system. A dynamic STPA methodology is also proposed as an extension to the basic methodology.
本文提出了一种将系统理论过程分析（STPA）方法应用于监测和跟踪糖尿病（DM）的社会技术系统的方法。在分层安全控制结构中，考虑了几个人类控制器，如患者、医生、其他医疗保健提供者以及社会环境中的人。在识别人类控制器不安全控制行为的因果因素（因果场景）时，考虑了 France（2017）提出的三阶段方法以及分层安全控制结构中各子系统之间的相互作用问题，并将基本安全设计程序的实施纳入系统改进方法中。还提出了一种动态 STPA 方法作为基本方法的扩展。
