Abstract: | This article describes a two-year surveillance of neurosurgical site infections and an outbreak of infections in deep brain stimulation (DBS) cases. From April to December 2008, six patients had a DBS surgical site infection (SSI). Audits of hygiene practices, infection control of the healthcare environment, and preoperative antimicrobial prophylaxis characteristics were carried out. The results of surgical audits showed that skin preparation and antimicrobial prophylaxis were not being performed adequately. In 2008, the general SSI rate was 1.8% (27 SSIs/1471 patients). Length of preoperative stay was significantly longer among infected patients (2.7 ± 2.9 months) compared with uninfected patients (2.2 ± 4.6 months) (P=0.01). Based on these results, skin preparation and antimicrobial prophylaxis were reviewed with the neurosurgery team. In 2009, the general SSI rate was reduced to 1.1% (16 SSI in 1410 patients), a reduction from 2008 (P=0.12). Although the overall incidence of SSI in 2008 (1.8%) was within the range of published data, this surveillance of SSIs permitted identification of site operative infected patients surgically treated for DBS. A set of actions was then taken to reduce SSI risk. This work demonstrates how an active surveillance programme can successfully change clinical care practice. |
