Epidemiology and outcomes of bacterial meningitis in the neonatal intensive care unit.

OBJECTIVE: Examine pathogen distribution, antibiotic resistance patterns, and hospital outcomes of infants with bacterial meningitis in neonatal intensive care units (NICUs) in the US from 2013-2018. STUDY DESIGN: Infants were divided into 2 groups based on age at the time of meningitis: early-onset (0-3 days) and late-onset (>3 days). We compared demographics, clinical characteristics, epidemiology, hospital outcomes, distribution of organisms and resistance, and blood culture timing relative to cerebrospinal fluid culture. RESULTS: From 345 NICUs, 659 infants were diagnosed with bacterial meningitis. The cumulative incidence was 1.1-1.3 cases/1000 NICU discharges. Median gestational age was 33 weeks, median birth weight was 1910 grams, 12% failed hearing screening, and 9% died prior to discharge. Of 141 cases of E. coli meningitis, 53% were resistant to ampicillin. CONCLUSIONS: Significant morbidities occur in infants with culture-proven meningitis in NICUs. Culture and subsequent discernment of sensitivity are crucial to guide definitive therapy.
