Acute bacterial meningitis: where do children die?
Insights
Childhood bacterial meningitis has a high fatality rate. Treatment location significantly impacts survival, with general hospitals showing higher mortality rates than infectious-disease or teaching hospitals.
Area of Science:
- Pediatrics
- Infectious Diseases
- Epidemiology
Background:
- Childhood acute bacterial meningitis remains a significant cause of mortality.
- High case-fatality rates necessitate investigation into treatment and outcomes.
Purpose of the Study:
- To analyze the relationship between hospital treatment location and case-fatality rates in childhood bacterial meningitis.
- To identify factors contributing to mortality in pediatric meningitis cases.
Main Methods:
- Retrospective review of 687 childhood acute bacterial meningitis cases with 72 deaths.
- Analysis of patient treatment location (infectious-disease, teaching, general hospitals) and timing of death.
- Comparison of case-fatality rates across different hospital types.
Main Results:
- General, non-teaching hospitals had a significantly higher case-fatality rate (11%) compared to infectious-disease (3%) and teaching hospitals (3%).
- Excluding early deaths post-admission reduced but did not eliminate the disparity between hospital types.
- 22% of deaths occurred before reaching hospital care or upon admission, indicating a critical pre-hospitalization phase.
Conclusions:
- Improving treatment facilities in some hospitals may reduce overall mortality from childhood bacterial meningitis.
- A substantial proportion of deaths occur before or shortly after hospital admission, highlighting the need for timely access to specialist care.
- Hospital type plays a role in outcomes, but pre-hospital factors are also critical in pediatric meningitis mortality.
Abstract:
The case-fatality rate for acute bacterial meningitis in childhood is still disappointingly high. A review of 687 cases of acute bacterial meningitis including 72 deaths, identified in a defined population of children under ten years of age, was done to determine where patients were treated and where they died. Ten per cent of all hospital admissions were to infectious-disease hospitals, 16 per cent to teaching hospitals, and 74 per cent to general, non-teaching ("regional-board") hospitals. The case-fatality rates associated with these hospitals were three per cent, three per cent and 11 per cent respectively. The difference between regional-board and other hospitals was smaller, although still present, when children who died within a few hours of hospital admission were excluded from the analysis. Twenty-two per cent of all deaths (10 children who died outside hospital and six who were certified dead on admission) occurred before specialist care was reached. It may be possible to reduce the mortality from this disease by improving facilities for treatment in some hospitals. There is, however, an important residue of deaths--those which occur before hospital care is reached and, no doubt, some of those which occur soon after hospital admission--which would be unaffected by such improvements.
