应用品管圈降低多重耐药菌医院感染及定植发生率的效果分析

Implementation of quality control circle reduces nosocomial infections and multidrug-resistant organism colonization

目的探讨品管圈(QCC)活动在降低多重耐药菌(MDROs)医院感染发生率和院内定植发生率,从而减少MDROs院内交叉传播中的效果。方法针对医院内MDROs感染及定植发生情况,实施QCC活动,并通过医院信息系统及医院感染预防与控制全流程管理系统对相关数据进行采集。将2023年1月—3月作为QCC改善前阶段,2023年4月—6月作为QCC改善阶段,2023年7月—9月作为QCC改善后阶段,统计改善前后MDROs医院感染发生率和院内定植发生率以及重点科室、重点措施落实情况,并进行结果对比。结果实施QCC活动以来,MDROs医院感染发生率和院内定植发生率分别从0.38%和0.35%下降至0.13%和0.09%,差异具有统计学意义(P<0.05),针对MDROs的防控措施执行率以及重点科室的执行情况明显好转。结论QCC活动有利于降低MDROs医院感染的发生率和院内定植发生率,减少MDROs在院内的交叉传播风险,提高医疗质量,保障患者生命安全。

Objective To assess the effectiveness of quality control circle(QCC)in diminishing the occurrence of nosocomial infections and the colonization of multidrug-resistant organisms(MDROs),thereby mitigating nosocomial transmission of MDROs.Methods QCC was initiated in our hospital in response to MDRO infections and colonization,and data were collected from the hospital's information system and the comprehensive management system for infection prevention and control.The pre-QCC period(January-March,2023),QCC period(April-June,2023),and post-QCC period(July-September,2023)were compared in terms of the incidence of nosocomial infection and colonization of MDROs as well as the implementation of key measures in major departments.Results Following the implementation of QCC,the incidence of nosocomial infection and in-hospital colonization of MDROs significantly decreased from 0.38%and 0.35%to 0.13%and 0.09%,respectively(both P<0.05).Additionally,the implementation rate of prevention and control measures for MDROs and the implementation in major departments have markedly improved.Conclusion QCC is effective in reducing the incidence of nosocomial infections and colonization of MDROs,mitigate the risk of cross-transmission of MDROs within hospitals,enhance the quality of healthcare delivery,and improve patient safety.
