Introduction: pneumococcal meningitis is a critical public health problem with a high rate of morbidity and mortality and serious sequelae. Objectives: identify some risk factors associated with mortality due to pneumococcal meningitis. Methods: a case-control study was conducted of 45 patients aged 0-86 with confirmed pneumococcal meningitis cared for in seven Havana hospitals from January 2002 to December 2011. Of the 45 patients studied, 15 had died (cases) and 30 had survived (controls). The study was based on national bacterial neurological syndrome surveillance data, medical records, hospital movements, notifiable disease cards and laboratory records. Association (bivariate and multivariate analysis) of some factors with death was measured through odds ratio with a confidence interval of 95 %, considering it an association if greater than or equal to 2. Results: overall case-fatality rate was 33.3 %. Mean time between the onset of symptoms and medical consultation was 2.4 days; between consultation and admission 0.5 day; between admission and diagnosis 0.4 day; and between diagnosis and treatment 0.2 day. Mean hospital stay was 12.2 days. Bivariate and multivariate analysis revealed a significant association between unconsciousness at admission and death. Other variables were associated with death as well, but they were not significant. Conclusions: being unconscious at admission is a risk factor for death due to pneumococcal meningitis in patients with this disease in the Havana hospitals studied.
