2010—2014年某妇幼保健院医院感染现患率调查

目的了解某妇幼保健院医院感染现状及抗菌药物使用情况，为更好地预防和控制医院感染提供依据。方法采用横断面调查，以及查阅电子病历与床旁调查相结合的方法，对 2010-2014年该院住院患者进行医院感染现患率调查。结果2010-2014年医院感染现患率分别为3.29%、5.20%、3.97%、3.93%、3.73%。医院感染现患率居首位的科室为儿科(9.09%～12.96%)，感染部位以上呼吸道居首位(50.00%~69.56%)。住院患者抗菌药物使用率分别为50.19%、41.40%、23.40%、25.47%、23.92%，逐年下降（χ2=133.40，P<0.001）；预防用药率高达57.38%~75.47%；单一用药率均＞95%。结论2010-2014年该院住院患者抗菌药物使用率总体呈下降趋势，但预防用药比例高，医院应加强抗菌药物使用的管理。

Prevalence rates of healthcare associated infection in a maternal and child health hospital in 2010-2014

Objective To investigate the prevalence rates of healthcare-associated infection（HAI）and antimicrobial use in a maternal and child health hospital,so as to provide reference for preventing and controlling HAI.Methods A cross-sec-tional survey on HAI prevalence of all hospitalized patients from 2010 to 2014 was conducted by combination of bedside ex-amination and medical record review.Results The prevalence rates of HAI in 2010—2014 was 3.29%,5.20%,3.97%, 3.93% and 3.73% respectively.HAI mainly occurred in patients at department of pediatrics （9.09%-12.96%）,the major infection site was upper respiratory tract （50.00%-69.56%）.Antimicrobial usage rate was 50.19%,41.40%, 23.40%,25.47% and 23.92% respectively,which decreased year by year （χ^2 = 133.40,P 〈0.001 ）;antimicrobial prophylactic usage rate was as high as 57.38%-75.47%;single usage rate were all〉95%.Conclusion Antimicrobial a-gents used by hospitalized patients showed a overall downward trend from 2010 to 2014.,but antimicrobial prophylactic us-age rate is high,management of antimicrobial agents should be strengthened.
