摘要
目的:构建口腔消毒供应不良事件知识图谱,设计智能化口腔医疗器械消毒供应不良事件风险评估模型与风险因素分析控制系统,通过系统应用提高口腔器械消毒供应质量.方法:通过数据接入服务实现口腔器械消毒供应数据自动化采集、转换和载入,采用失效模式与效应分析(FMEA)和动态风险评价理论构建口腔消毒供应不良事件知识图谱,采用递归神经网络(RNN)构建消毒供应不良事件风险预测模型及根因分析法,对口腔器械消毒供应不良事件进行风险评估及根因分析.结果:口腔器械清洗不良事件前4项风险因素分别为清洗参数设置错误、清洗后器械有污渍、清洗后管腔清洗未达标和清洗后器械存在水垢,系统预测概率分别为4.67%、2.33%、1.50%和1.39%,与事实发生概率的2.14%、1.85%、0.75%和0.50%总体保持一致.消毒器械表面存在水渍不良事件前4项风险因素为消毒设备温度设置过高、消毒设备消毒时长过久、消毒器械表面污物残留和加热管水垢残留,与实际统计结果前4项风险因素构成比顺序一致.结论:智能化口腔医疗器械消毒供应不良事件风险评估模型与风险因素分析控制系统应用,能够及时发现口腔器械消毒供应操作环节质量隐患并实施风险控制,提高口腔器械消毒供应质量.
Abstract
Objective:To construct a knowledge graph,to design an intelligent risk assessment model for adverse events and a risk factor analysis control system for the disinfection supply of stomatological medical devices,and improve the quality of disinfection supply of stomatology instruments through system application.Methods:The automatic collection,conversion and loading of stomatological medical devices disinfection supply data were realized by constructing data access services,the knowledge graph of adverse events of stomatology disinfection supply was constructed by using failure mode and effect analysis(FMEA)and dynamic risk assessment theory,and the risk prediction model and root cause analysis method of adverse events of disinfection supply were constructed by using recurrent neural network(RNN),and the risk assessment and root cause analysis of adverse events of stomatology medical devices disinfection supply were carried out.Results:The top four risk factors of the adverse events of"cleaning"in disinfection supply were incorrect cleaning parameter settings,stains on the instrument after cleaning,substandard lumen cleaning after cleaning,failure to meet the standard of luminal cleaning after cleaning,and scale presence in the instrument after cleaning,respectively,and the systematic prediction probabilities were 4.67%,2.33%,1.50%,and 1.39%,respectively,which were consistent with the actual probability of occurrence of 2.14%,1.85%,0.75%,and 0.50%.The top four risk factors for the adverse event of"water stains on the surface of disinfection equipment"were too high temperature setting of disinfection equipment,too long disinfection time of disinfection equipment,residual dirt on the surface of disinfection equipment and scale residue of heating pipe,which were consistent with the composition order of the first four risk factors in the actual statistical results.Conclusion:The application of the risk assessment model of adverse events and the risk factor analysis and control system of intelligent stomatological medical device disinfection supply can timely discover the quality hidden dangers in the operation of stomatology device disinfection supply and implement risk control,and provide reference for the construction of related business systems.
