Diagnosis and management of bacterial meningitis in adult Sudanese patients: a six years hospital based, retrospective, cross-sectional study.

ABSTRACT

PURPOSE: To evaluate the diagnosis and management of bacterial meningitis in adult Sudanese patients in accordance with the Infectious Diseases Society of America (IDSA) guidelines for bacterial meningitis management. PATIENTS AND METHODS: A cross-sectional, retrospective study design was used to recruit all patients aged > 18 years who were diagnosed with or suspected of having bacterial meningitis and admitted to Wad Medani Teaching Hospital, Gezira State, Sudan, between January 2017 and October 2022. RESULTS: In total, 201 patients were included in the analysis. The mean age of the participants was 44.1 ± 21.4 years, and 107 (53.2%) were male. Community-acquired bacterial meningitis accounted for 193 (96%) of the studied patients, and only 8 (4%) of the patients had healthcare-associated meningitis. Neuroimaging was utilized appropriately in 148 (73.6%) patients, blood cultures were not performed entirely, and lumbar puncture was seldom performed in 1 (0.5%) patient. Corticosteroids were appropriately administered to 65 (32.3%) patients, and antibiotics were administered appropriately to only 5 (2.5%) patients. Ceftriaxone 185 (76.1%) was the most frequently utilized antibiotic, followed by vancomycin 23 (9.5%). In terms of overall adherence, this study demonstrated that the IDSA guidelines were not followed at all in the treatment of patients with suspected bacterial meningitis. CONCLUSION: The results of this study contradict the IDSA guidelines for the standard of care for bacterial meningitis. Antibiotic regimens are often incorrect, corticosteroids are administered appropriately in approximately one-third of patients, and neuroimaging is reasonably utilized. This study raises attention to several important issues regarding the diagnosis of bacterial meningitis, including the lack of confirming microbiological tests and the reliance of the diagnosis primarily on CT and clinical examination.
