Effect of monitor during preventive process on the control of indwelling urinary catheterassociated urinary tract infection FREE

摘要:

目的在“过程监控”基础上提出“预防性过程监控”概念及可行的监控方法，实验性应用于留置导尿相关泌尿系感染的控制中，评价监控方法的有效性。方法将某院神经内科2007年1—7月留置导尿的155例患者设为对照组，2007年8月—2008年2月留置导尿的141例患者设为实验组；对照组执行留置导尿常规护理，实验组除进行常规护理外，采用评估督促和宣传教育等方法进行预防性过程监控。结果实验组留置导尿相关泌尿系感染率为4.26%，明显低于对照组的16.13%（χ2=11.10，P＜0.01）；两组患者留置导尿的时间比较，实验组70%的患者留置导尿时间在13.10 d内，明显低于对照组的18 d；留置导尿11～30 d、＞30 d时，实验组导尿相关泌尿系感染率分别为6.67%、16.67%，明显低于对照组的30.77%、57.89%（分别χ2=8.27，P＜0.01；χ2=5.13，P＜0.05）。结论评估督促和宣传教育等预防性过程监控可有效预防医院感染。

Abstract:

ObjectiveTo establish the concept of “monitor during preventive process” as well as  the feasibility of surveillance and control method, and apply the method on the control of indwelling urinary catheterassociated urinary tract infection(UTI). Methods155 inpatients who received indwelling urinary catheter in a neurology department between January and July, 2007 were as control group, 141  inpatients who received indwelling urinary catheter between August, 2007 and February, 2008 were as trial group; Control group received routine nursing for indwelling catheter, trial group received monitor during preventive process (such as evaluation, supervision and education) in addition to routine nursing.ResultsIndwelling urinary catheterassociated UTI in trial group and control group was 4.26% and 16.13%, the former was significantly lower than the latter (χ2=11.10, P<0.01); In trial group, the duration of catheterization in 70% patients was within 13.10 days, which was significantly lower than 18 days in control group; When duration of catheterization were 11-30 days,>30 days, urinary catheterassociated UTI in  trial group was 6.67% and 16.67% respectively, which was obviously lower than 30.77% and 57.89% in control group(χ2=8.27, P<0.01; χ2=5.13, P<0.05).ConclusionMonitor during  preventive process can prevent nosocomial infection effectively.
