A 15-year retrospective analysis of prognostic factors in childhood bacterial meningitis

Area of Science:

• Pediatrics
• Infectious Diseases
• Neurology

Background:

• Childhood bacterial meningitis remains a significant cause of morbidity and mortality worldwide.
• Identifying predictors of disease severity and long-term sequelae is essential for timely intervention and improved patient outcomes.

Purpose of the Study:

• To identify factors predicting disease severity and long-term outcomes in childhood bacterial meningitis.
• To utilize intensive care unit (ICU) admission as a marker for disease severity in a low-mortality cohort.

Main Methods:

• Retrospective chart review of 112 microbiologically confirmed bacterial meningitis cases in children (3 days to 15 years).
• Data collected from a Singapore hospital between 1998 and 2013.
• Analysis of factors associated with ICU admission and long-term sequelae.

Main Results:

• The mortality rate was 6%, with 44% requiring ICU admission.
• Predictors for ICU admission included pneumococcal meningitis, leukopenia, and a low cerebrospinal fluid (CSF):serum glucose ratio.
• Haemophilus influenzae type b (Hib) meningitis, inpatient seizures, and septic shock were associated with long-term sequelae in 32% of survivors.

Conclusions:

• Pneumococcal and Hib meningitis are significant risk factors for severe disease and long-term complications.
• Early identification of predictive factors can guide management and improve prognoses.
• The findings highlight the critical importance of pneumococcal and Hib vaccination programs in preventing severe childhood meningitis.
