In healthcare, most accidents occur as a result of inadequate interactions between system components rather than component failures. In such cases traditional risk analysis methods are of limited use for analysing system safety, so methods such as Systems Theoretic Process Analysis (STPA) and the Functional Resonance Analysis Method (FRAM) have been developed. This study uses STPA to assess risks in the sepsis treatment process, discusses the potential value STPA adds and compares the results of STPA with the results of another study that used FRAM. The findings indicate that STPA and FRAM have different strengths which reflect the different scientific approaches behind these two methods. FRAM facilitates an in-depth understanding of a system, while STPA allows for more comprehensive risk analysis by identifying more risks, scenarios and safety recommendations. Nevertheless, it is reasonable to say that not only does STPA provide more comprehensive risk analysis; its terminology and philosophy are also closer to the current safety management applications employed in complex systems.

在医疗保健领域，大多数事故是由于系统组件之间交互不足而不是组件故障造成的。在这种情况下，传统的风险分析方法在分析系统安全方面的用途有限，因此开发了系统理论过程分析 (STPA) 和功能共振分析方法 (FRAM) 等方法。本研究使用 STPA 来评估脓毒症治疗过程中的风险，讨论 STPA 增加的潜在价值，并将 STPA 的结果与使用 FRAM 的另一项研究的结果进行比较。研究结果表明 STPA 和 FRAM 具有不同的优势，这反映了这两种方法背后的不同科学方法。FRAM 有助于深入了解系统，而 STPA 允许通过识别更多风险进行更全面的风险分析，场景和安全建议。尽管如此，可以说 STPA 不仅提供了更全面的风险分析；它的术语和理念也更接近于当前在复杂系统中使用的安全管理应用程序。
