ObjectiveTo study the present situation of hospital orthopedic surgery incision infection, in order to provide the basis for further intervention. MethodsProspective investigation combined with retrospective investigation method was adopted in our study to perform a statistical analysis on orthopedic surgery incision infections among 545 patients in our hospital between January and December 2012. ResultsDuring the one year of follow-up, there were 10 cases of surgical incision infection among all the 545 patients, with an infection rate of 1.83%. The infection rate of class-Ⅰ incision was 0.46%, of class-Ⅱ was 5.13%, and of class-Ⅲ/Ⅳ was 12.12%, and the Cochrane-Armitage trend chi-square test showed significant trend among them (χ2=28.273, P<0.001). Based on different operation risk index, patients with index 1, 2, 3 had a surgical site infection rate of 0.82%, 2.60%, and 18.75%, respectively. The higher the index, the higher the surgery incision infection rate, and the trend was statistically significant (χ2=12.916, P<0.001). The infection rate was 1.43% for elective surgical procedures, and was 3.15% for emergency surgery, but there was no significant difference (P>0.05). ConclusionOrthopedic surgery has a high-risk surgical site infection rate, and incision classification and surgical risk index have statistical correlation with the incidence of hospital infection. In order to ensure the security of patients and reduce medical disputes, we should pay close attention to orthopedic surgery infection.
