Abstract

Background and objectives: Medical risks are considered to endanger patients and impact the health care system. Such iatrogenic risks necessitate hospitals taking a more proactive method to quantitatively analyze medical risk, and then to implement more targeted precautions. To address this problem, a novel quantitative risk assessment framework is proposed and further applied in radiotherapy risk assessment.

Methods: A framework combining DMAIC (Define, Measure, Analyze, Improve, Control) and bow-tie model is used to assess health care risk. The uncertainty of medical risks is quantified with fuzzy set theory. The impact and the priority of medical risks were classified based on the risk matrix, and then the precautions were implemented to mitigate their impact. A case study of radiation treatment is provided.

Results: The probabilities and impacts of risk events for radiation treatment were quantified based on the proposed framework, and risk protection measures were proposed to mitigate the undesired consequence.

Conclusion: The proposed framework showing an effective method of quantitative risk assessment of health care. The study also enriches the risk assessment methods in health care by providing a conductive and normalized framework.

将 DMAIC 理念和 Bow-Tie 模型整合到医疗保健的定量风险评估中。

背景和目标：医疗风险被认为会危及患者和影响医疗系统。这种先天性风险要求医院采取更积极的方法对医疗风险进行定量分析，然后实施更有针对性的预防措施。针对这一问题，本文提出了一个新颖的定量风险评估框架，并将其进一步应用于放射治疗风险评估：方法：采用 DMAIC（定义、测量、分析、改进、控制）框架和领结模型来评估医疗风险。采用模糊集理论量化医疗风险的不确定性。根据风险矩阵对医疗风险的影响和优先级进行分类，然后实施预防措施以减轻其影响。结果：结果：根据提出的框架，量化了放射治疗风险事件的概率和影响，并提出了风险防护措施，以减轻不良后果：结论：所提出的框架展示了定量评估医疗风险的有效方法。结论：所提出的框架展示了一种有效的医疗保健定量风险评估方法，该研究还提供了一种可传导的规范化框架，从而丰富了医疗保健风险评估方法。

期刊介绍： Quality Management in Health Care (QMHC) is a peer-reviewed journal that provides a forum for our readers to explore the theoretical, technical, and strategic elements of health care quality management. The journal''s primary focus is on organizational structure and processes as these affect the quality of care and patient outcomes. In particular, it: -Builds knowledge about the application of statistical tools, control charts, benchmarking, and other devices used in the ongoing monitoring and evaluation of care and of patient outcomes; -Encourages research in and evaluation of the results of various organizational strategies designed to bring about quantifiable improvements in patient outcomes; -Fosters the application of quality management science to patient care processes and clinical decision-making; -Fosters cooperation and communication among health care providers, payers and regulators in their efforts to improve the quality of patient outcomes; -Explores links among the various clinical, technical, administrative, and managerial disciplines involved in patient care, as well as the role and responsibilities of organizational governance in ongoing quality management.
