ABSTRACT: Introduction
Comparison of rates of ventriculostomy-related infections (VRIs) across institutions is difficult due to the lack of a standard definition. We sought to review published definitions of VRI and apply them to a test cohort to determine the degree of variability in VRI diagnosis.Materials and methods
We conducted a PubMed search for definitions of VRI using the search strings "ventriculostomy-related infection" and "ventriculostomy-associated infection." We applied these definitions to a test cohort of 18 positive cerebrospinal fluid (CSF) cultures taken from ventriculostomies at two institutions to compare the frequency of infection using each definition.Results
We found 16 unique definitions of VRI. When the definitions were applied to the test cohort, the frequency of infection ranged from 22 to 94% (median 61% with interquartile range (IQR) 56-74%). The concordance between VRI diagnosis and treatment with VRI-directed antibiotics for at least seven days ranged from 56 to 89% (median: 72%, IQR: 71-78%).Conclusions
The myriad of definitions in the literature produce widely different frequencies of infection. In order to compare rates of VRI between institutions for the purposes of qualitative metrics and research, a consistent definition of VRI is needed.
