目的:基于工作链和可拓物元模型构建安全运行管理路径,探讨其在磁共振成像(MRI)设备临床管理中的应用效果.方法:从MRI设备工作链角度,制定人员、设备、环境及制度层面的安全风险评价指标,采用可拓物元模型进行设备安全特征指标的等级评定并制定风险控制管理策略.选取2019年1月至2021年12月舒城县人民医院影像科在用的1台MRI设备,2019年1月至2020年6月的MRI设备运行期间采用标准流程管理模式(简称标准流程模式)进行管理,2020年7月至2021年12月的MRI设备运行期间采用风险评估控制模式(简称风险控制模式)进行管理,对比两种不同管理模式下MRI设备的安全风险事件控制率、安全运行管理规范度及工作人员业务能力水平.结果:采用风险控制模式管理MRI设备的62例安全风险事件中,极其危险、高度危险和显著危险事件控制率分别为1.61%(1/62)、4.84%(3/62)、8.06%(5/62),均低于标准流程模式,其差异有统计学意义(x2=5.613、4.567、9.241,P＜0.05);采用风险控制模式管理开展的480例安全运行检查中,患者接诊、设备使用、运行环境和管理制度的规范度分别为96.25%(462/480)、98.96%(475/480)、99.17%(476/480)和97.50%(468/480),均高于标准流程模式,其差异有统计学意义(x2=18.631、17.563、7.353、8.789,P＜0.05);采用风险控制模式管理的影像科MRI检查技师、护士及医学工程处工程师的年度考核成绩分别为(91.87±4.56)分、(94.54±3.27)分和(91.45±4.95)分,均高于标准流程模式,其差异有统计学意义(t=3.291、4.277、4.292,P＜0.05).结论:基于工作链和可拓物元模型的风险控制管理模式可全面挖掘MRI设备安全运行影响因素,有效控制高风险事件发生率,提高MRI设备临床运行质量和操作管理规范.
Abstract
Objective:To construct a safe operation management path based on work chain and extension matter-element model,and to explore its application effect in clinical management of magnetic resonance imaging(MRI)equipment.Methods:The safety risk evaluation indicators was developed from the perspective of MRI equipment work chain at the levels of personnel,equipment,environment and system.The rating of safety characteristic indicators of equipment was carried out and risk control management strategy was formulated by adopting extensible matter element model.The MRI equipment in clinical use in the Imaging Department of Shucheng People's Hospital from January 2019 to December 2021 was selected,and the standard process management mode(referred to as standard process mode)and risk assessment control mode(referred to as risk control mode)were adopted respectively for equipment operation management.The safety risk event control rate,safety operation management standardization and professional capability of staff of MRI equipment under two different management modes were compared.Results:Among 62 safety risk events of MRI equipment managed by risk control mode,the control rates of extremely dangerous,highly dangerous and significant dangerous events were 1.61%(1/62),4.84%(3/62)and 8.06%(5/62),respectively,which were lower than those of the standard process mode,the difference was statistically significant(x2=5.613,4.567,9.241,P<0.05).Among 480 cases of safety operation inspection carried out by risk control mode management,the standardization of patient reception,equipment use,operating environment and management system were 96.25%(462/480),98.96%(475/480),99.17%(476/480)and 97.50%(468/480),respectively,which were higher than those of the standard process mode,the difference was statistically significant(x2=18.631,17.563,7.353,8.789,P<0.05).The annual assessment scores of MRI technicians,nurses and medical engineering engineers of the imaging department adopting risk control mode were(91.87±4.56)points,(94.54±3.27)points and(91.45±4.95)points,respectively,which were higher than those of the standard process mode,the difference was statistically significant(t=3.291,4.277,4.292,P<0.05).Conclusion:The risk control management mode based on work chain and extension matter-element model can comprehensively explore the factors affecting the safe operation of MRI equipment,effectively control the incidence of high-risk events,improve the quality of clinical operation and operation management of MRI equipment.
