目的了解医院重症监护病房(ICU)高频接触物体表面的洁净度情况,规范医务人员清洁方法,防控多重耐药菌的传播。方法对ICU环境的高频接触物体表面进行采样,应用ATP生物荧光法进行检测,计算出合格率,运用鱼骨图分析结果,找出缺陷的主要因素。结果干预前共采样140件,99件不合格,合格率仅为29.3%。其中移动护理站、电脑键盘和鼠标的合格率最低。不合格的99件中,50件应用医用消毒巾立即进行擦拭消毒后检测,合格率为96%;49件应用75%酒精纱布擦拭,合格率为79.6%,两组消毒效果差异有统计学意义(P<0.05)。结论ATP生物荧光法进行ICU高频接触物体表面检测洁净度较差,存在交叉感染的风险,需进一步强化护理人员医院感染防控的意识,规范擦拭方法,使用清洁消毒一步法的消毒湿巾效果更佳。
Objective To understand the cleanliness of high-frequency contact objects in intensive care unit (ICU) in hospitals and to standardize the cleaning methods of medical staff to prevent and control the spread of multi-resistant bacteria. Methods The surface of high frequency contact object in ICU environment was sampled and detected by ATP biofluorescence method. The pass rate was calculated and the result of fishbone analysis was analyzed to find out the main factors of defect. Results Before the intervention a total of 140 samples were collected, 99 were unqualified, with a pass rate of only 29.3%. Including mobile nursing station, computer keyboard and mouse pass rate is the lowest. Of the 99 cases that failed, 50 were disinfected immediately with wipes and disinfected, and the pass rate was 96%. 49 of them were cleaned with 75% alcohol gauze and the pass rate was 79.6%. There was significant difference in disinfection effect between the two groups (P <0.05). Conclusion The ATP biofluorescence method has a poor cleanliness and high risk of cross-infection. It is necessary to further strengthen awareness of prevention and control of nosocomial infections among nursing staffs, to standardize the wiping method, and to use the disinfection wet-wipe effect of one-step cleaning and disinfection Better.
