As a result of these findings, the corresponding author began systematically applying concentrated bacitracin powder directly to wounds during shunt surgery more than 5 years ago. The object of this study was to evaluate the effectiveness of concentrated bacitracin powder applied directly to wounds prior to closure during cranial shunt surgery and to evaluate the association between shunt infection and other risk factors. A single surgeon\u2019s cranial shunt surgery experience, equally divided between periods during which antibiotic powder was and was not applied, was studied to assess the effect of concentrated bacitracin powder application on shunt infection rates.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>This retrospective cohort study included all patients who underwent a cranial shunting procedure at All Children\u2019s Hospital performed by a single surgeon (G.F.T.) from 2001 to 2013. The surgeon applied bacitracin powder to all shunt wounds prior to closure between 2008 and 2013, whereas no antibiotic powder was applied to wounds prior to 2008. Both initial and revision shunting procedures were included, and all procedures were performed at a large children\u2019s hospital (All Children\u2019s Hospital). The primary outcome measure was shunt infection, which was defined using clinical criteria previously used by the Hydrocephalus Clinical Research Network. The association between bacitracin powder use and shunt infection was estimated using hazard ratios (HRs) and 95% CIs from Cox proportional hazard regression models.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>A total of 47 infections out of 539 shunt operations occurred during the study period, resulting in an overall infection rate of 8.7%. Procedures performed before the use of concentrated bacitracin powder was instituted resulted in a 13% infection rate, whereas procedures performed after systematic use of bacitracin powder had been adopted experienced a 1% infection rate. Bacitracin powder use was associated with a reduced risk of shunt infection in univariate analysis (HR 0.11, 95% CI 0.03\u20130.34, p = 0.0002) and also in multivariate analysis (HR 0.12, 95% CI 0.04\u20130.41, p = 0.0006) when controlling for covariates that were associated with infection from the univariate analysis. The presence of a tracheostomy or a gastrostomy tube was also found to be independently associated with shunt infection in multivariate analysis (HR 3.15, 95% CI 1.05\u20139.50, p = 0.04, and HR 2.82, 95% CI 1.33\u20135.96, p = 0.007, respectively).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>This study suggests, for the first time, that the systematic application of concentrated bacitracin powder to surgical wounds prior to closure during shunt surgery may be associated with a reduction in cranial shunt infection. This initial finding requires validation in a large prospective study before widespread application can be advocated.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2014.12.peds13675","type":"journal-article","created":{"date-parts":[[2015,9,18]],"date-time":"2015-09-18T13:59:13Z","timestamp":1442584753000},"page":"648-661","source":"Crossref","is-referenced-by-count":22,"title":["Reduction in CSF shunt infection over a 10-year period associated with the application of concentrated topical antibiotic powder directly to surgical wounds prior to closure"],"prefix":"10.3171","volume":"16","author":[{"given":"Joshua M.","family":"Beckman","sequence":"first","affiliation":[{"name":"Department of Neurosurgery and Brain Repair, Morsani College of Medicine, University of South Florida, Tampa, Florida;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ernest K.","family":"Amankwah","sequence":"additional","affiliation":[{"name":"Department of Clinical and Translational Research and"},{"name":"Department of Pediatrics, Johns Hopkins School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa L.","family":"Tetreault","sequence":"additional","affiliation":[{"name":"Department of Clinical and Translational Research and"},{"name":"Neuroscience Institute, All Children\u2019s Hospital\/Johns Hopkins Medicine, St. Petersburg, Florida; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerald F.","family":"Tuite","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Brain Repair, Morsani College of Medicine, University of South Florida, Tampa, Florida;"},{"name":"Neuroscience Institute, All Children\u2019s Hospital\/Johns Hopkins Medicine, St. Petersburg, Florida; and"},{"name":"Department of Pediatrics, Johns Hopkins School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-peds13675","series-title":"Acta Neurochir (Wien)","doi-asserted-by":"publisher","first-page":"1259","DOI":"10.1007\/s00701-009-0317-2","article-title":"Antibiotic-impregnated ventriculoperitoneal shunts in patients at high risk of infection","volume":"151","author":"Albanese","year":"2009"},{"key":"b2-peds13675","series-title":"Surg Neurol Int","doi-asserted-by":"publisher","first-page":"22","DOI":"10.4103\/2152-7806.64966","article-title":"Topical antibiotics and neurosurgery: Have we forgotten to study it?","volume":"1","author":"Alves","year":"2010"},{"key":"b3-peds13675","series-title":"J Bone Joint Surg Am","first-page":"1415","article-title":"Comparison of soap and antibiotic solutions for irrigation of lower-limb open fracture wounds.
