Risk factors for deep infection in the surgical site after spinal operations

Introduction Despite significant steps in prevention and treatment of infectious complications after surgical treatment on the spine, many issues remain unsolved. There is a sufficient number of scientific reports on the treatment of postoperative infection, however, only a few studies present multivariate analysis of risk factors of developing deep infection after surgical intervention. In the domestic literature, such reports are rare. According to most sources, the rate of infection after spinal interventions ranges from 0.7 to 11.9 %. Material and methods We conducted a retrospective multivariate analysis of the data collected to determine the risk factors of deep surgical infection after spinal surgery at various levels and volumes. To fully determine the risk factors, not only surgical factors were evaluated, but also individual characteristics of patients contributing to the increase in infection rates. The purpose of this study was to compare patients who developed local deep infection after spine surgery, with a randomly selected group of patients who did not develop this complication, to identify modifiable risk factors...
