Аннотация:A total of 4021 patients were included and 359 were diag- nosed with meningitis resulting in an incidence of 8.9% (95% CI: 8.45–9.38). The incidence of meningitis decreased from 15.6% to 6.5% during the study period (Figure 1). The mortality rate in patients with meningitis was 23.4% (95% CI: 22.2–243.6) that did not change over time. The etiological spectrum was dominated by CoN Staphilococcus (30%) followed by Acinetobacter baumannii (23%) and Klebsiella pneumoniae (23%). The mortality rate was higher in patients infected with Acinetobacter baumannii.
