INTRODUCTION: Acute bacterial meningitis (ABM) continues to be a challenge from a diagnostic and therapeutic point of view. Identifying severity risk factors and predictive scores may guide interventions to reduce poor outcome.

METHODS: Data from a retrospective study for ABM in children admitted to the Institute of Tropical Medicine in Paraguay was analyzed. ABM was defined as positive cerebrospinal fluid culture, positive latex agglutination, or identification of microorganism by real time-polymerase chain reaction. Univariate and multivariate analyses of risk factors at hospital admission that predicted major morbidity or death during hospitalization were performed. A point-based scoring system that included variables, which were clearly different among those who passed away, was constructed.

RESULTS: One hundred fourteen children hospitalized with ABM were eligible for the study. The mean age was 46 ± 57 months (range, 1-192 months). The observed mortality was 33% (38/114 patients). When a point-based scoring system was used, for score of 0 (n = 29) and 1 (n = 12), no death was observed. Among patients with a score of 2 (n = 14), 3 (n = 10 patients), 4 (n = 12 patients), and 5 (n = 13 patients), the mortality rate was 14.3%, 40%, 50%, and 53.8%, respectively. When the score was 6 or higher, the mortality rate was at least 63.6%.

CONCLUSIONS: The present score accurately discriminated the probability of death in children hospitalized with ABM, and it could be a useful tool to select candidates for admission to the intensive care unit and for adjunctive therapy in clinical trials.
