目的 评价手卫生健康教育对重症监护病房（ICU）患者家属手卫生依从性的影响。 方法 选取2012年3月－5月ICU患者家属558人，对其进行手卫生健康教育。将健康教育前的1个月定义为第1阶段(基线调查阶段），健康教育当月定义为第2阶段，健康教育结束后的第1个月定义为第3阶段。对ICU患者家属开展手卫生健康教育，第1和第3阶段均采用张贴展板和宣教图片，床旁准备速干手消毒液；第2阶段在此基础上，每周示范六步洗手法3次，由责任护士督促并指导家属使用速干手消毒液进行手卫生。观察3个阶段患者家属手卫生依从性变化情况。 结果 在对“接触患者前”、“接触患者后”和“接触患者周围环境后”3个手卫生时机的依从率比较中，第2阶段明显高于第1阶段（P＜0.01）；第3阶段较第2阶段有明显下降（P＜0.01）；在3个阶段中，使用速干手消毒液进行手卫生的人数均高于使用洗手液的人数。 结论 手卫生健康教育普及了手卫生相关知识，提高了ICU患者家属对手卫生的依从性。
Objective To explore the role and significance of full-time infection control nurses in the prevention and control of nosocomial infection in Intensive Care Unit (ICU). Methods Before Februry 2013, there was no full-time infection control nurses in ICU in West China Hospital of Sichuan University (before implementation); since March 2013, with a comprehensive evaluation of bed numbers and infection control nurses workload, the job of full-time infection control nurses were initiated (after implementation). The management of infection control was achieved through clarifying the responsibility of full-time infection control nurses, the implementation of infection monitoring and other related measures. Results Comparing to the condition before implementation, the hand hygiene compliance among nurses, doctors, workers and cleaners in ICU elevated from 49.8% to 74.9%, the infected rate decreased from 15.3% to 9.3%, the positive rate of multiple resistant bacteria decreased from 18.3% to 13.5%, the incidence of ventilator-associated pneumonia decreased from 13.02‰ to 6.63‰, and central venous catheter-related bloodstream infection rate decreased from 6.559‰ to 2.422‰; the differences were all significant (P<0.05). The incidence of urinary tract infection decreased from 1.21‰ to 1.07‰, and the difference was significant (P>0.05). Conclusions Full-time infection control nurses can introduce continuous and effective training to medical staffs, supervise the execution of hospital infection prevention and control measures, and examine all steps involved and relevant feedbacks. Therefore, the full-time infection control nurses play an important role in the prevention and control of nosocomial infection in ICU.
