Abstract
Objective. To determine the outcomes of bacterial meningitis in school-age survivors. Design. Prospective cohort study. Setting. Teaching pediatric hospital. Children. During 1983 through 1986, 158 meningitis survivors, ages 3 months to 14 years, treated at a single center were enrolled. Between 1991 and 1993, 130 children, 82% of the original cohort, were evaluated at a mean age of 8.4 years and a mean of 6.7 years after their meningitis. Outcome measures. Blinded neurologic, neuropsychologic, audiologic, behavior, and socio-demographic assessments were compared with those from grade- and sex-matched control children. Multivariate analyses adjusted for age at testing and socio-demographic variables. Results. There was a systematic increase in risk of abnormality or poorer functioning for children with meningitis, compared with control children, across all categories tested, which was significant for fine motor function, Intelligence quotient (IQ) scores, and tests of school behavior, neuropsychologic function, and auditory figure-ground differentiation. Eleven children who had experienced meningitis (8.5%) had major deficits (IQ Conclusions. One in four school-age meningitis survivors has either serious and disabling sequelae or a functionally important behavior disorder, neuropsychologic or auditory dysfunction adversely affecting academic performance. As a group, survivors function less well than their classroom peers, and risk is greatest for, but not confined to, those who had acute neurologic complications. All survivors require careful follow-up, at least until school age.
