目的 探讨风险矩阵评估在介入导管室防控新型冠状病毒肺炎中的应用效果。 方法 对16名专家进行2轮专家咨询,确定了传染源、传播途径、易感人群、防控能力4个一级指标、14个二级指标;将二级指标以感染发生可能性为纵坐标,感染发生所引发后果严重性为横坐标,建立介入导管室发生新型冠状病毒肺炎院内感染二维风险矩阵模型;针对5个高风险和3个中风险指标制订并实施应急防控措施。 结果 2020年1月23日—2月26日介入导管室顺利完成107例患者的介入手术,患者及医护人员均无发生院内感染。 结论 运用风险矩阵评估,发现主要潜在风险因素,采取针对性防控措施,避免了介入导管室发生新型冠状病毒肺炎院内感染。

Objective To explore the effects of risk matrix assessment in prevention and control of COVID-19 in interventional catheterization room. Methods Two rounds of expert consultations were conducted with 16 experts. Four primary indicators including infection sources,transmission routes,susceptible populations,and prevention and control capabilities were identified. Besides,14 secondary indicators were also determined. A two-dimensional risk matrix was established with the infection possibility as the vertical ordinate and outcome severity as the abscissa for all secondary indicators. Emergency prevention and control measures were developed for 5 high-risk and 3 medium-risk indicators. Results From 23 January to 26 February in 2020,107 interventional procedures were successfully completed in the interventional catheterization room. No patients and medical staffs caught the infection. Conclusion The risk matrix assessment can help identify the main potential risk factors. Targeted prevention and control measures can therefore be taken to prevent COVID-19 infection in the interventional catheter room.
