Any procedure carries the risk of a surgical site infection (SSI). Infections raise financial demands and have a detrimental effect on patient morbidity and mortality. The aim of this research was to look into SSI and the factors that contribute to it in patients who had thoracic or lumbar spine surgery.

A 6-year single-centre prospective observational cohort study monitored the incidence of SSI in 274 patients who received planned thoracic or lumbar spinal surgery for degenerative disease, trauma, or tumour. They were monitored for up to 30 days postoperatively and again after 1 year. All patients received short antibiotic prophylaxis and stayed in the eight-bed neurointensive care unit (NICU) during the immediate postoperative period. Risk factors for SSI were sought using multivariate logistic regression analysis.

--22 incidences of SSI (8.03%; superficial 5.84%, deep 1.82%, and organ 0.36%) were recorded .

--Comparing patients with and without SSI, there were no differences in age, gender, body mass index, spine diagnosis, number of vertebrae, spine localization, implant use, American Society of Anesthesiologists (ASA) Score, urine catheterization , drainage, corticosteroid use, transfusion, ulcer prophylaxis and diabetes mellitus.

--The SSI group had longer NICU stays and more non-infectious hospital wound complications.

--SSI risk factors according to our multivariate logistic regression analysis were hospital wound complications (OR 20.40) and warm season (OR 2.92).

Conclusively, this study did not identify corticosteroids, diabetes mellitus, or transfusions as risk factors for the development of SSI. Only wound complications and warm seasons were significantly associated with SSI development according to this multivariate regression analysis.
