BACKGROUND: Few Japanese hospitals can perform in-house cerebrospinal fluid (CSF) polymerase chain reaction (PCR) to screen for herpes simplex virus, leading to patients being administered acyclovir (ACV) for several days. The FilmArray Meningitis/Encephalitis Panel (ME Panel) is a multiplex PCR test that can identify 14 major pathogens within 1 h. We aimed to investigate the efficacy of the ME Panel in children admitted with central nervous system infections in Japan.
METHODS: We conducted a single-center, quasi-experimental study. The ME panel was introduced in April 2020. We outsourced the CSF samples to a laboratory during the pre-intervention period (April 2016 to March 2020) and performed the ME panel at our hospital during the post-intervention period (April 2020 to December 2021). Duration and dose of ACV and antibiotic use, length of stay (LOS) in the pediatric intensive care unit (PICU), and total LOS after testing were compared using the Mann-Whitney U test.
RESULTS: The number of cases in the pre- and post-intervention periods was 67 and 22 cases, respectively. The median duration of ACV decreased significantly from 6 days to 0 day (p < 0.001), and the median dose of ACV use decreased significantly from 14 vials to 0 vial (p < 0.001). No significant differences were noted in the total duration and dose of antibiotic use, LOS in PICU, and the total LOS after testing.
CONCLUSION: The introduction of ME panel may contribute to appropriate ACV use; however, there was no significant change in the duration and dose of antibiotic use or LOS.
