Age as an independent risk factor for surgical site infections in a large gastrointestinal surgery cohort in Japan
Journal of Hospital Infection
Volume 75, Issue 3, July 2010, Pages 183-187
Summary
A large scale survey was conducted to examine risk factors for surgical site infections (SSIs) among Japanese patients undergoing gastrointestinal surgery. The purposes of the study were: (i) to investigate age as a risk factor for SSIs in gastrointestinal surgery; and (ii) to examine the differences in risk factors for SSIs between laparoscopic cholecystectomy and open cholecystectomy. Surveillance data were prospectively collected from 20 participating hospitals in Japan between July 2003 and November 2007. SSIs were identified by use of the Centers for Disease Control and Prevention criteria. SSIs were identified in 1471 of 12 015 available cases, with an overall incidence of 12.2%. In the final logistic regression model, age was a risk factor in open cholecystectomy, gastrectomy and appendicectomy. Length of operation was a risk factor for SSIs for six surgical procedures, and wound class and drain use were also risk factors in most procedures. When comparing laparoscopic surgery against open procedure, use of silk sutures was a risk factor for SSIs in laparoscopic cholecystectomy. Drain use, wound class, operation duration, male gender and age were additional risk factors for SSIs in open cholecystectomy. In summary, patient age is a significant predictor for SSIs in some gastrointestinal procedures, although risk factors for SSIs in laparoscopic procedures appear quite different from those in open procedures.

摘要
一项大规模调查，是进行检查手术部位感染日本之间进行胃肠手术病人（SSI的）风险因素。这项研究的目的是：（一）调查作为在胃肠手术SSI的危险因素年龄;（二）研究腹腔镜胆囊切除术和开腹胆囊切除术SSI的危险因素的差异。前瞻性地收集监测数据，从2003年7月至2007年11月在20所参加调查的日本医院中。确定标准使用了由美国疾病控制和预防中心的使用标准。 SSI的确定在现有12 015中有 1471例，12.2％的总发病率。在最后的logistic回归模型，发现年龄是开腹胆囊切除术、胃切除术及阑尾切除术的危险因素。手术时间的长短是外科手术SSI的危险因素，并清理伤口类也是最危险的因素。对比腹腔镜手术，在腹腔镜手术时使用丝线也是在腹腔镜胆囊切除术SSI的危险因素。排泄用途，伤口类，手术时间，性别和年龄，尤其是男性和年龄为开腹胆囊切除术SSI的增加了额外的风险因素。总之，患者的年龄是在某些胃肠道手术SSI的显著的差异，尽管在腹腔镜手术中SSI的危险因素似乎有点与开放的规程不同。
