Nosocomial meningitis in a university hospital between 1993 and 2002.
The aim of this study was to establish the relationship between nosocomial meningitis (NM) and surgical interventions, type of pathogens and other hospital infections (HIs). Fifty-one patients diagnosed with NM, according to the criteria of the Centers for Disease Control and Prevention, in the Neurosurgery Department of Ibn-i Sina Hospital of Ankara University between 1993 and 2002 were evaluated retrospectively. All individuals with NM were hospitalized in the intensive care unit. Third-generation cephalosporins were used for surgical prophylaxis and broad-spectrum antibiotics were used for treatment. NM occurred in 0.34% of all admissions and accounted for 0.53% of all HIs. Fourteen cases (28%) had at least one concurrent HI, mainly originating from surgical wounds and related secondary bacteraemia. Four cases had NM following surgical site infection with the same causative agent and three cases had bacteraemia. All the individuals had surgical interventions and 26 (51%) had operations concerning ventriculoperitoneal shunt. A positive microbiological cause was found in the cerebrospinal fluid of 49 patients, with 16 cases having a polymicrobial cause. Of all 67 micro-organisms isolated, 41 (61%) were Gram-negative bacilli, 23 (34%) were Gram-positive cocci and the remaining three (5%) were Candida spp. Staphylococci were the most common pathogens (30%), followed by non-fermentative Gram-negative bacilli (22%).
