基于Kaiser模型的灾害脆弱性分析在CT-Sim定位中的应用
Application of Hazard Vulnerability Analysis Based on Kaiser Model in CT-Sim Localization
摘要
Abstract
Objective:Hazard vulnerability analysis was used to identify the patient's safety risk factors in computed tomography simulation(CT-SIM)localization,and to identify the key factors and preventive measures.Methods:A total of 21 experts in CT-Sim from radiotherapy centers in China were invited to conduct an investigation and study.Using Kaiser model,the safety risk factors of patients during CT-Sim were identified by brainstorming among the experts.Factors were en-tered into the Kaiser model and assessed from both the probability and the harmfulness of the risk factors.With the probabili-ty of occurrence weighted and the severity score statistically processed,calculate the relative risk coefficient of each risk fac-tor.Results:The top 5 safety risk factors during CT-Sim were fracture risk coefficient of bone metastasis patients(47.18％),scan failure risk coefficient of non-cooperation of children pa-tients(43.56％),image error risk coefficient of irregular breathing of patients(43.47％),asphyxia risk coefficient of high-risk patients(39.15％),and asphyxia risk coefficient of anaphylaxis of patients during enhanced scan(37.13％).Conclusion:The application of hazard vulnerability analysis to evaluate the risk factors of CT-Sim is helpful for CT-Sim lo-calization workers to understand the key risk factors,carry out coping exercises and improve medical safety.关键词
