Surgical associated factors — preoperative radiation/postoperative blood transfusion , combined anterior/posterior approach , surgical invasiveness , or levels of instrumentation were associated with increased SSI .
There is mixed evidence of age , duration of surgery , surgical team , intraoperative blood loss , dural tear , and urinary tract infection/urinary catheter in association with SSI .
Conclusion : SSIs are associated with many risk factors that can be patient or surgically related .
Objective : To perform a review of SSI risk factors and more specifically , categorize them into patient and surgical factors .
Prospective multicenter surveillance and risk factor analysis of deep surgical site infection after posterior thoracic and/or lumbar spinal surgery in adults
Background Surgical site infection is a serious and significant complication after spinal surgery and is associated with high morbidity rates , high healthcare costs and poor patient outcomes . Accurate identification of risk factors is essential for developing strategies to prevent devastating infections . The purpose of this study was to identify independent risk factors for surgical site infection among posterior thoracic and /or lumbar spinal surgery in adult patients using a prospect i ve multicenter surveillance research method . Methods From July 2010 to June 2012 , we performed a prospect i ve surveillance study in adult patients who had developed surgical site infection after undergoing thoracic and /or lumbar posterior spinal surgery at 11 participating hospitals . Detailed preoperative and operative patient characteristics were prospect ively recorded using a st and ardized data collection format . Surgical site infection was based on the definition established by the Centers for Disease Control and Prevention . Results A total of 2,736 consecutive adult patients were enrolled , of which 24 ( 0.9 % ) developed postoperative deep surgical site infection . Multivariate regression analysis indicated four independent risk factors . Preoperative steroid therapy ( P = 0.001 ) , spinal trauma ( P = 0.048 ) and gender ( male ) ( P = 0.02 ) were statistically significant independent patient-related risk factors , whereas an operating time ≥3 h ( P < 0.001 ) was a surgery-related independent risk factor . Conclusion Preoperative steroid therapy , spinal trauma , male gender and an operating time ≥3 h were independent risk factors for deep surgical site infection after thoracic and /or lumbar spinal surgery in adult patients . Identification of these risk factors can be used to develop protocol s aim ed at decreasing the risk of surgical site infection
