TSimon TD, et al. - Researchers aimed at assessing the variation in patient and treatment characteristics for children with first cerebrospinal fluid (CSF) shunt infection, stratified by infecting organism subgroups outlined in the 2017 Infectious Disease Society of America’s (IDSA) guidelines. In this prospective cohort of 145 children <18 years of age, infections were diagnosed by CSF culture and addressed by IDSA guidelines, including 47 with Staphylococcus aureus, 52 with coagulase-negative Staphylococcus, 37 with Gram-negative bacilli, and 9 with Propionibacterium acnes. They noted no differences in many patient and treatment characteristics between infecting organism subgroups, including age at initial shunt, gender, race, insurance, indication for shunt, gastrostomy, tracheostomy, ultrasound, and/or endoscope use at all surgeries before infection, or numbers of revisions before infection. When antibiotic-impregnated catheters were used, differences in the organism profile encountered at infection was noted, with a higher proportion of Gram-negative bacilli.
