肺功能检查导致医院感染的调查分析

Nosocomial infections induced by lung function examination

目的分析引起肺功能检查医院感染的原因,为临床降低肺功能检查医院感染提供参考。方法选取2011年1月-2011年12月医院诊治行肺功能检查的患者作为研究对象,根据患者肺功能检查时间分为观察组154例和对照组146例;对照组肺功能检查按常规进行,观察组加强医院感染控制;对两组患者检查期间感染控制及医院感染发生情况进行观察,分析引起肺功能检查医院感染的原因。结果对照组患者发生医院感染21例,感染率14.4%,观察组患者无医院感染发生,两组感染率差异有统计学意义;导致医院感染的相关因素,主要为检测环境、规范操作、仪器设备清洗消毒和工作人员卫生等方面;观察组环境、设备表面、工作人员手部和防护服菌检分别为(3.6±1.7)CFU/m3、(5.6±2.7)CFU/cm2、(7.4±2.6)CFU/cm2和(27.8±12.8)CFU/cm2。结论加强肺功能检查医院感染控制,能够有效减少医院感染发生;对可能引起患者医院感染的各个环节加强控制,对于防止肺功能检查医院感染和保证医患健康有重要意义。

OBJECTIVE To analyze the causes of nosocomial infections induced by lung function examination so as to provide guidance for the reduction of incidence of nosocomiaI infections induced by the lung function examination. METHODS The patients who underwent the lung function exarrlination in the hospital from Jan 2011 to Dec 2011 were enrolled in the study and divided into the observation group with 154 cases and the control group with 146 cases according to the time of lung function examination, then the control group was treated with the routine examination method, the observation group was received the intensified control of nosocomial infections, the control of infections and the incidence of infections were observed and compared between the two groups during the examination, and the causes of the lung function examination-related infections were analyzed. RESULTS The nosocomial infections occurred in 21 cases in the control group with the infection rate of 14.4% and did not occur in the observation group, with statistical significance in the infection rate between the two groups. The major related factors for the nosocomial infections included the detection environment, operation, cleaning and disinfection of instruments, and hygiene of staff. In the observation group, the bacterial colony counts in the environment was （3.6±1.7）CFU/m3 , surfaces of equipment （5.6±2.7）CFU/cm2 , staff＇s hands （7.4±2.6）CFU/ cm2 , protective clothes （27. 8 ±12.8）CFU/ cm2. CONCLUSION It is an effective way to strengthen the control of nosocomial infections during the lung function examination and focus on the links of control that may result in the nosocomial infections so as to prevent the lung function examination-related infections and ensure the health of patients.
