目的分析六西格玛管理法对留置导尿管患者医院感染发生率的影响。方法选取2012年7月~2014年7月我院收治的200例留置导尿管患者，依据随机数字表法将这些患者分为两组，即观察组(100例)和对照组(100例)。给予对照组患者常规护理，给予观察组患者六西格玛管理法护理，然后对两组患者的医院感染发生率进行统计分析。结果观察组患者第1、3、5、7d医院感染发生率分别为0、4%(4/100)、10%(10/100)、20%(20/100)，对照组患者第1、3、5、7d医院感染发生率分别为4%(4/100)、12%(12/100)、22%(22/100)、33%(33/100)。观察组患者各时间点医院感染发生率均明显低于对照组(P<0.05)。结论六西格玛管理法能够有效降低留置导尿管患者医院感染发生率，值得在临床推广。“,”Objective Influence of Six Sigma Management Act of indwel ing catheter in patients with nosocomial infection incidence.Methods Select from July 2012 to July 2014 in our hospital 200 cases of patients with indwel ing catheter,according to a random number table These patients were divided into two groups,namely the observation group(100 cases)and control group(100 cases).Routine care given to patients in the control group,the observation group were given Six Sigma Care Management Act,and then the two groups of patients with hospital infection rates for statistical analysis.Results The first group of patients observed incidence of nosocomial infection 1,3,5,7d 0,4%respectively (4/100),10%(10/100),20%(20/100),the control group of patients 1,3,5,7d hospital infection rate of 4%(4/100),respectively,12%(12/100),22%(22/100),33%(33/100).The observation group were nosocomial infections occur each time point were significantly lower than the control group ( <0.05).Conclusion Six Sigma management method can ef ectively reduce the indwel ing catheter in patients with hospital infection rates,worthy of promotion.
