Abstract
OBJECTIVES: Surgical site infection [SSI] increases mortality, morbidity and length of hospital stay. Peri-operative 'care bundles' have reduced SSI in some fields of surgery. The aim of this study was to determine the impact of bundle compliance on SSI in patients undergoing a craniotomy. PATIENTS AND METHOD: Cohort study of patients [N=1253] undergoing a craniotomy over 17 months at a single centre. SSI was defined as arising within 30days of operation or 1year where an implant(s) remains. 'Bundle compliance' required administration of antibiotics <60min of induction, maintenance of intraoperative blood sugar (BM) <11mmol and temperature at >36°C. SSI incidence was compared between bundle compliant and non-compliant groups. Case mix adjustment was performed using binary logistic regression. RESULTS: Over the study period, 1253 procedures were carried out and 66 patients (5.3%) developed a SSI. The majority (38, 57.6%) of these cultured Staphyloccoccus species. Only the use of an implant was found to be an independent risk factor for SSI [AOR 2.5, p<0.005, 95%CI 1.4, 4.3]. The use of the bundle did not reduce the occurrence of SSI. CONCLUSIONS: An evidence-based bundle did not reduce SSI in this neurosurgical series. The use of an implant was an independent risk factor of its occurrence.
