2009年医院感染发病率及其病原体分布

Incidence rate of nosocomial infection and distribution of pathogenic bacteria in 2009

目的了解2009年医院感染发病率及病原体分布。方法采用前瞻性调查为主,回顾性调查为辅的方法,对2009年医院33 547例住院患者进行调查。结果 956例发生医院感染,其中1例发生3次医院感染,24例发生2次感染,共982例次,例次感染率2.93%;主要感染部位为上呼吸道感染649例,占66.09%,下呼吸道感染115例占11.71%,消化道感染152例占15.48%,切口感染32例占3.26%;病原微生物培养送检764例,送检率为77.80%;主要病原体有肺炎链球菌152株,酵母样真菌62株,轮状病毒54株,大肠埃希菌45株,屎肠球菌10株,铜绿假单胞菌8株;医院感染发生日期中位数为入院后6 d。结论医院感染监测与抗菌药物应用策略应作为感染控制的重点工作。

OBJECTIVE To describe the incidence rate of nosocomial infection and the distribution of pathogenic micro-organisms of Children′s Hospital of Shanxi Province and Maternal and Child Health Care of Shanxi Province in 2009.METHODS All the hospital patients of 33 547 were investigated with prospective study mainly and retrospectively study.RESULTS Totally 956 hospital patients acquired HAI,of which 1 occurred three times and 24 occurred two times,the total cases were 982 and an overall case-time rate of 2.93%.The infection sites were upper respiratory tract 649 cases（66.09%） and lower respiratory tract 115 cases（11.71%） and gastrointestinal tract152 cases（15.48%） and incision tract 32 cases（3.26%）.764 specimens which accounted for 77.80% were detected.The main pathogenic microorganisms were 152 Streptococcus pneumoniastrains,62 yeast-like fungi,54 rotavirus antigen-positive and 45 Escherichia coli,10 cases of Enterococcus faces,8 Pseudomonas aeruginosa.The median date of HAIs was 6 days after admission,quartile range was 6 days too.CONCLUSION HAI surveillance and the strategies for application of antibiotics should be used as the focus of the work.
