目的探讨强化ICU环境卫生对医院感染控制的效果。方法通过多种措施改进ICU环境卫生状况并结合调查方法,将环境卫生改善前后3次与医院感染发生率进行比较分析。结果 ICU内微生物检测结果显示,医护人员手和物体表面均是混合污染条件致病菌的载体,从ICU环境、物体表面、医护人员手检出细菌多为芽孢、革兰阳性等非致病菌,但不动杆菌、肺炎克雷伯菌、沙雷氏菌和肠球菌等条件致病菌亦广泛存在。医院感染与环境监测结果表明,3次的环境卫生学监测合格率逐次增加(P<0.05),病房感染率也是逐次降低(P<0.05),说明强化干预措施取得了较好效果。结论 ICU感染率与环境监测合格率不存在相关关系,但这只说明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 ICU sanitation on hospital infection control. Methods By means of various measures to improve the condition of ICU’s sanitation and the method of investigation, the incidence of nosocomial infection was compared with that of nosocomial infection three times before and after the improvement of sanitation. Results The results of microbiological tests in ICU showed that the surface of hands and objects of medical staff were carriers of pathogenic bacteria mixed with contaminated conditions. Most of the bacteria were spore and gram positive in ICU environment, , But Acinetobacter, Klebsiella pneumoniae, Serratia and enterococci and other conditions of pathogens are also widespread. Hospital infection and environmental monitoring results showed that three times the environmental hygiene monitoring pass rate increased successively (P <0.05), ward infection rate is also decreased (P <0.05), indicating that enhanced interventions have achieved good results. Conclusion There is no correlation between ICU infection rate and environmental monitoring pass rate. However, this only shows that environmental health monitoring is not the main concern index for evaluating hospital infection management. Both of them are not unrelated, and hospital infection management can not be done simply by environmental disinfection monitoring Complete control of the occurrence of nosocomial infections.
