Prevention and control effect of core system key index intervention on nosocomial infection of inpatients in department of cardiology

目的探讨核心制度关键指标干预对心内科住院患者医院感染的防控效果。方法选择2013年7月-2014年12月于医院心内科住院治疗750例患者为对照组,另选择2015年1月-2016年6月于医院心内科住院治疗750例患者为干预组,对照组采用常规干预模式进行干预,干预组在此基础上采用核心制度关键指标干预模式进行干预,对比两组心内科住院患者的医院感染率、医院感染部位、感染病原菌分布与生活质量。结果干预组住院患者医院感染率为1.1%显著低于对照组4.8%,差异有统计学意义(P<0.01),对照组患者的主要感染部位包括呼吸系统、泌尿系统和消化系统,干预组主要感染部位包括呼吸系统和泌尿系统;心内科医院感染病原菌中革兰阴性菌占64.6%,以大肠埃希菌、肺炎克雷伯菌为主,分别占20.8%、16.7%;革兰阳性菌占29.2%,以金黄色葡萄球菌为主占12.5%;真菌占6.3%;干预组心内科住院患者的日常生活评分、活动评分、健康评分、总体精神评分、近期支持评分以及生活质量总指数评分均显著高于对照组,差异有统计学意义(P<0.05)。结论将核心制度关键指标干预应用于心内科住院患者医院感染的防控中,可以显著降低心内科住院患者医院感染率,改善患者生活质量。

OBJECTIVE To investigate the prevention and control effect of core system key index intervention on nosoeomial infections of ~npatients in department of cardiology. METHODS A total of 750 patients in department of cardiology of our hospital from Jul. 2013 to Dec. 2014 were selected as control group, and another 750 patients in department of cardiology of our hospital from Jan. 2015 to Jun. 2016 were selected as intervention group. Patients in control group were treated with routine intervention, and in intervention group were adopted the core sys- tem key index intervention mode on the basis of control group. The nosocomial infection rates, nosocomial infec- tion sites, infection pathogen distribution and the quality of life of the inpatients between the two groups in department of cardiology were compared. RESULTS The nosocomial infection rate of intervention group was 1. 1%, which was significantly lower than 4.8% of control group （P〈0.01）. The main infection sites of control group included the respiratory system, urinary system and digestive system, and the main infection sites of the interven- tion group included the respiratory system and urinary system. Department of cardiology, The nosocomial infection pathogens in department of cardiology included gram-negative bacteria of 64.6%, which were mainly Esche- richia coli and Klebsiella pneumoniae, accounting for 20.8 % and 16.7% gram-positive bacteria of 29.2%, which were mainly Staphylococcus aureus, accounting for 12.5%, and fungi of 6.3%. The daily living score, activity score, health score, general mental score, recent support score and general quality of life of intervention group were significantly higher than those of control group （P〈0.05）. CONCLUSION Application of the core system key index intervention in prevention and control of nosocomial infection of inpatients in department of cardiology, can significantly reduce the nosocomial infections rate of inpatients in department of cardiology, and improve the quality of life of patients.
