Objective To evaluate the risk factors for surgical site infection(SSI)following limb fracture surgery, and provide basis for making prevention and control measures.Methods Clinical data of 1 453 patients undergoing limb fracture surgery in 16 hospitals between January 1,2014 and June 30,2014 were collected,risk factors for SSI were analyzed by univariate and multivariate logistic regression analysis.Results Among 1 453 patients undergoing limb fracture surgery,12 developed SSI(0.83%).Univariate analysis showed that risk factors for SSI following limb fracture surgery were infection at the other sites 7 days before operation,time from injury to operation,opera-tion opportunity, duration of operation,open fracture, wound type, and anesthesia type ( all P < 0.05 ). Multivariate logistic regression analysis showed that independent risk factors were wound type,anesthesia type, open fracture,time from injury to operation,and duration of operation,OR(95% CI)were 12.47(2.78-15.88), 11.55(2.84 - 17.02),10.79 (2.72 - 11.13 ),2.35 (2.12 - 6.81 ),and 3.07 (1.88 - 4.13 )respectively. Conclusion Risk factors for SSI following limb fracture surgery are multiple,the key to the prevention and control of SSI are identifying risk factors and strengthening the management of key points.

Objective To understand characteristics and research status of literatures related to surgical site infec-tion(SSI)in China.Methods Literatures about SSI published between January 2000 and March 2016 were retrieved from China National Knowledge Infrastructure(CNKI),VIP database,Vanfang Database,and China Biology Medi-cine(CBM)database. Bibliometric method was adopted to analyze external and internal characteristics of literatures. Results A total of 1036 articles in Chinese were included,40(3.86% ),189(18.24% ),and 807(77.90% )were published in 2000-2005,2006-2010,and the first quarter of 2011-2016 respectively. Articles were mainly pub-lishedinChineseJournalofNosocomiology(n= 226,21.81% ),ChineseJournalofInfectionControl(n= 53, 5.12% ),andChineseJournalofDisinfection(n= 27,2.61% ). The research fields included risk factors(n= 277, 26.74% ),infection rates (n= 261,25.19% ),antimicrobial application (n= 208,20.08% ),and pathogens (n=153,14.77% );the infection rates were higher in general surgery and neurosurgery,the main pathogens were Esch-erichiacoli,Staphylococcusaureus,and Pseudomonasaeruginosa,risk factors mainly included the types of incision, duration of surgery,diabetes,age,and body mass index.Conclusion In recent years,articles about SSI research in-creases significantly,research in etiology and epidemiology has gained substantial achievement,but in the interven-tion and economics is still weak,suggesting that SSI research in economics,risk management,and behavioral aspects should be strengthened.
