Abstract:

Objective To construct and apply a multidrug-resistant bacteria information management system，and evaluate its effectiveness and accuracy in the management of patients with multidrug-resistant bacteria infection. Methods A system construction team was established to develop a multidrug-resistant bacteria information management system，which includes 4 modules：early warning，execution，monitoring，and statistical decision-making. Patients with positive detection of multidrug-resistant bacteria admitted to a tertiary A obstetrics and gynecology hospital in Zhejiang Province from January to December 2022，members of the system construction team，and clinical medical staff were selected as the research subjects. The execution efficiency of multidrug-resistant bacteria management，as well as the system’s accuracy，usability，and satisfaction were compared before（January to June 2022） and after（July to December 2022） the application of the system. Results After the implementation of the system，the immediate feedback rate of multidrug-resistant bacteria early warning information increased from 62.87% to 89.78%；the rate of issuing isolation medical orders rose from 61.07% to 93.33%；the accuracy of the implementation of isolation measures for patients increased from 66.67% to 98.01%；all differences are statistically significant（P<0.001）. The accuracy rate of the system in making decisions is 88.44%；the usability score given by medical staff for the system is 44.04 points，and the satisfaction score of the system construction team members and medical staff to the system is 121.25 points，both at a high level. Conclusion The multidrug-resistant information management system is equipped with features such as immediate alerts，multi-channel notifications，infection control department supervision，and auxiliary decision-making，which can provide medical staff with accurate decision reports. Preliminary application results show that the system has a high level of accuracy and good usability.

摘要：

目的 构建多重耐药菌感染信息管理系统并初步应用，评价其在多重耐药菌检出阳性患者管理过程中的有效性及准确性。 方法 成立系统构建小组，构建多重耐药菌感染信息管理系统，包括预警、执行、监测、统计决策4个模块。选取2022年1月—12月浙江省某三级甲等妇产科医院的多重耐药菌检出阳性住院患者、系统构建小组成员、临床医务人员作为研究对象，系统应用后（2022年7月—12月）与应用前（2022年1月—6月），对多重耐药菌感染管理的执行效率及系统的准确性、可用性、满意度进行评价。 结果 系统应用后，多重耐药菌感染预警的即刻反馈率由62.87%上升至89.78%，隔离医嘱开具率由61.07%上升至93.33%，隔离措施执行准确率由66.67%上升至98.01%，差异具有统计学意义（P<0.001）。系统产生决策报告的准确率为88.44%，医务人员对于系统的可用性评价平均得分为44.04分，系统构建小组成员、临床医务人员对系统的满意度平均得分为121.25分，均处于高水平。 结论 构建的多重耐药菌感染信息管理系统具备即刻提醒、多途径通知、多方监管、辅助决策等功能，能够为医务人员提供较准确的决策报告。初步应用结果显示，该系统的准确性较高、可用性良好。
