不同级别医院手术部位感染现患率调查

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P0.05);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。

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

ObjectiveTo explore the occurrence of surgical site infection(SSI) in patients in different levels of hospitals.MethodsSSI among patients in 47 hospitals at 0:00-24:00 of May 16,2012 were investigated by medical record reviewing, doctor inquiry, and bed side visiting.ResultsA 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(χ2=9.337, P=0.002);SSI prevalence rates in clean contaminated and contaminated incision in secondary hospitals were both higher than tertiary hospitals (χ2=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.ConclusionSSI rates of different types of incision and different departments are varied, corresponding prevention and control measures should be taken.
