Bacteremia Is a Risk Factor for Cerebrospinal Fluid Infection in Patients with Cerebrospinal Fluid Drains—A Retrospective Study

There is little evidence on the role of prior infection in patients with external ventricular drains (EVDs) and lumbar (LDs). In this study, our aim to investigate whether previous bacteremia a risk factor for cerebrospinal fluid drain (CSFDI) EVDs LDs describe microorganisms implicated. We designed retrospective, single-center cohort study. recorded patients’ demographic clinical characteristics, as well microbiology laboratory data. used non-parametric statistical methods identify possible factors CSFDI. found 799 neurosurgical admissions during study period, 70 which fulfilled inclusion criteria. Acinetobacter baumannii was most frequent single pathogen isolated (CSF). more common CSFDI (p = 0.01).
