不同级别医院手术部位感染现患率调查

摘要

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 0:00-24:00 of May 16,2012 were investigated by medi-cal record reviewing,doctor inquiry,and bed-side visiting.Results A total of 5 977 surgical patients were investiga-ted,SSI prevalence rate was 1 .76%.SSI prevalence rate in secondary hospitals was higher than tertiary hospitals (χ2 =9.337,P =0.002);SSI prevalence rates in clean-contaminated and contaminated incision in secondary hospi-tals were both higher than tertiary hospitals (χ2 =4.315,8.129,both P <0.05);departments with high SSI preva-lence 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.%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5977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。
