Characteristics of Device-Associated Cerebrospinal Fluid Infection in Adults
- Abstract
- Objective:
Device-associated infections in the central nervous system are serious complications of procedures involving indwelling devices among neurosurgical patients. In this study, the clinical characteristics and outcome of microbiologically confirmed deviceassociated cerebrospinal fluid (CSF) infection were evaluated.
Methods:
We performed a retrospective analysis of adult patients found to have a positive CSF culture result during a hospital admission between 1 January 2005 through 2 October 2010 in Soonchunhyang University Hospital.
Results:
During the study period, all episodes (n=161 CSF specimens, 87 patients) involving a culture-positive CSF were enrolled. Thirty-two episodes of device-associated CSF infection were included in the analysis among the study group. Most device-associated infections were ventriculo-peritoneal shunt infections (14/32, 44%). Fever (>38°C) was present in 17 episodes (53%). Overall, the most common microorganism was coagulase-negative staphylococcus (7/32 [22%]). Gram-negative rods (Pseudomonas aeruginosa 6/32 [19%], Acinetobacter baumannii/haemolyticus 5/32 [16%]) were identified in culture in 16/32 (50%). Device was removed for the control of device-associated infection in 30/32 (94%). Cure rate was 69% (22/32). All patients with treatment failure (10/32, 34%) expired.
Conclusion:
It is difficult to diagnosis device-associated CSF infections early since those are frequently presented with nonspecific clinical signs and symptoms. In our study, gram-negative infections accounted for 50% of cases and the empiric antibiotics initially chosen were found to not be effective against the final identified pathogen in many cases. Device-associated CSF infections should be strongly considered a serious risk factor associated with CSF infections, and prompt initiation of broad coverage antibiotics should be started after appropriate assessment.
