某医院两次医院感染现患率调查分析

Survey on prevalence rate of hospital infection of two consecutive years in a hospital

目的了解医院住院患者医院感染现患率及感染管理状况,评估重要危险因素的变化及相关感染的控制效率。方法采取横断面调查方法,选择2012年和2013年10月某日对某医院所有住院患者进行医院感染现患率调查,并对结果进行评估。结果 2012年和2013年该医院住院患者医院感染现患率分别为3.32%和2.71%,医院感染部位以下呼吸道感染居首位。2012年和2013年抗菌药物使用率平均为52.96%;病原学标本平均送检率为32.97%,医院感染病原菌主要是革兰阴性杆菌。结论该医院住院患者医院感染现患率高于日常感染率监测结果,表明日常监测上报感染率可能存在漏报现象,应加强感染监测和提高病原学标本送检率。

Objective To investigate the prevalence rate of hospital infection and the current status of hospital infection management,evaluate the changes of risk factors and infection control efficiency. Methods cross-sectional survey was used to investigate the prevalence of hospital infection among hospitalized patients through medical records review in one day on October,2012 and 2013. Results The prevalence rate of hospital infection were 3. 32% and 2. 71% in 2012 and 2013,respectively. The main infection site was lower respiratory tract. The average antibiotics usage rate was 52. 96%, and the average microorganism inspection rate was 32. 97%. The main pathogens causing hospital infection was Gram-negative bacteria. Conclusion The hospital infection prevalence rate is higher than that of daily monitoring,indicating in-fection cases were underestimated in daily work. It is suggested that we should strengthen monitoring and improve the in-spection rate of microorganism were the effective measures.
