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 .
Surgical-site infection in spinal injury: incidence and risk factors in a prospective cohort of 518 patients
Purpose To investigate the incidence of surgical-site infection ( SSI ) and determinate the risk factors of SSI in the context of spinal injury . Methods From February 1 , 2011 to July 31 , 2011 , for a multicentre cohort of patients with acute spinal injury , we prospect ively censored those with SSI for at least 12 months . We recorded epidemiologic characteristics and details of surgical procedure and postoperative care for each patient . We calculated the incidence of SSI at 1 , 3 and 12 months after surgery . Univariate and multivariate analysis were used to establish the association of risk factors and SSI . We studied clinical outcomes by a visual analog scale for pain and physical and mental component summaries ( PCS and MCS ) of the Medical Outcomes Survey 36-Item Short Form ( SF-36 )  . Results At 1 year , among 518 patients , we recorded 25 SSI events , with median occurrence at 16 days ( 25–75 % quartile : 13–44 days ) . Incidence of SSI was 3.2 % ( 95 % confidence interval [ 1.9–5.3 % ] ) at 1 month , 3.7 % ( 95 % [ 2.2–5.8 % ] ) at 3 months and 4.6 % ( 95 % CI [ 3–6.9 % ] ) at 12 months . On multivariate analysis , age , presence of diabetes and surgical duration were predictors of SSI ( p = 0.009 , p = 0.047 , and p = 0.015 respectively ) . At 12 months , infected and non-infected patients did not differ in pain ( p = 0.58 ) or SF-36 PCS ( p = 0.8 ) or MCS ( p = 0.68 ) . Conclusions In this large prospect i ve multicentre study in the context of spinal injury , we obtained an equivalent incidence rate and risk factors of SSI as found in the literature for elective spinal surgery
