ABSTRACT

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 000-2400 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.
