Strategies to reduce external ventricular drain–related infections: a multicenter retrospective study

OBJECTIVEVarious strategies have been proposed to reduce the incidence of external ventricular drain (EVD)–related infections. The authors retrospectively studied the impact of EVD care management on EVD-related infections at 3 French university hospital intensive care units.METHODSBetween 2010 and 2014, 462 consecutive adult patients with no evidence of a preexisting CSF infection received EVDs as part of their care at one of the following sites: Grenoble (221 patients), Saint-Etienne (130 patients), and Marseille (111 patients). Written protocols describing the EVD placement procedure, management, and removal were implemented at the 3 sites. Daily CSF sampling and intraventricular administration of antibiotics prior to EVD removal were performed at the Grenoble site only. EVD-related infection was considered for any confirmed ventriculostomy-related infection (VRI) and ventriculitis. VRI was defined as one or more positive CSF cultures or Gram stain with CSF pleocytosis and biochemical abnormalities. Ve...
