[目的]探讨强化ICU病房环境卫生的管理,对入住ICU的患者医院感染控制的效果。[方法]某院多次通过多种措施改进ICU环境卫生状况,并回顾性结合调查方法,将环境卫生改善前后5次与医院感染发生率比较分析。[结果]5次的环境卫生学监测合格率,逐次增加(P﹤0.05);病房的感染率也是逐次降低(P﹤0.05);环境监测合格率与医院感染发病率做二元变量相关分析,r=-0.39495,P=0.25872,二者不存在相关关系。[结论]该院的强化措施取得了较好的成果,但是环境卫生效果监测不是评价医院感染管理的主要关注指标,二者不是无关的,单纯通过环境消毒效果监测进行医院感染管理,并不能完全控制住医院感染的发生。 [Objective] To explore the effect of strengthening the management of ICU ward sanitation and hospital infection control in ICU patients. [Methods] A hospital adopted many measures to improve the environmental health status of ICU on many occasions, and retrospectively combined with the survey method to compare and analyze the incidence of hospital infection 5 times before and after the improvement of environmental health. [Results] The qualified rate of environmental hygiene monitoring in five times increased successively (P <0.05), and the infection rate in ward decreased successively (P <0.05). The environmental monitoring qualified rate and incidence of nosocomial infection were analyzed by binary variables. r = -0.39495, P = 0.25872, there is no correlation between the two. [Conclusion] The strengthening measures of this hospital have achieved good results, but the monitoring of environmental health effects is not the main indicator of evaluation of hospital infection management. Both of them are not unrelated to the hospital infection management simply by monitoring the effect of environmental disinfection and can not be completely Control the occurrence of nosocomial infections.
