不同级别医院手术部位感染现患率调查

Survey on prevalence rate of surgical site infection in different levels of hospitals

目的调查某区不同级别医院外科手术患者手术部位感染(SSI)发生情况。方法设计统一的调查表,按照统一的调查方法,结合查阅病例、询问主管医生、参加医生查房等调查方法,对某区47所医院2012年5月16日0∶00—24∶00外科手术后的住院患者进行SSI情况调查。结果共调查5 977例外科术后患者,SSI现患率为1.76%。二级医院SSI现患率高于三级医院(χ2=9.337,P=0.002);二级医院的清洁—污染切口、污染切口的SSI现患率均高于三级医院(χ2值分别为4.315、8.129,均P<0.05);SSI现患率较高的科室为普通外科、骨科、神经外科;感染病原菌主要为大肠埃希菌、金黄色葡萄球菌、凝固酶阴性葡萄球菌。结论该地区不同级别医院不同切口类型、不同科室SSI现患率均存在差异,应根据相关情况采取有针对性的预防与控制措施。

Objective To explore the occurrence of surgical site infection（SSI）in patients in different levels of hospitals.Methods SSI among patients in 47 hospitals at 0：00-24：00of May 16,2012 were investigated by medical record reviewing,doctor inquiry,and bed-side visiting.Results A total of 5 977 surgical patients were investigated,SSI prevalence rate was 1.76%.SSI prevalence rate in secondary hospitals was higher than tertiary hospitals（χ^2=9.337,P=0.002）;SSI prevalence rates in clean-contaminated and contaminated incision in secondary hospitals were both higher than tertiary hospitals（χ^2=4.315,8.129,both P〈0.05）;departments with high SSI prevalence rates were general surgery,orthopedic,and neurosurgery;the major isolated pathogens were Escherichia coli,Staphylococcus aureus,and coagulase negative Staphylococcus.Conclusion SSI rates of different types of incision and different departments are varied,corresponding prevention and control measures should be taken.
