title: Hospital-associated bacterial meningitis.
abstract: Eighteen of 349 cases (5.2 per cent) of bacterial meningitis seen between 1949 and 1973 were hospital-associated (developed after admission to the hospital). The patients were adults, usually males, and developed symptoms and signs of meningitis from 2 to 23 days (mean, 10.1 days) after hospital admission. The diagnosis of bacterial meningitis was made from less than 1 day to 15 days (mean, 4.8 days) after the onset of symptoms. Fourteen of the 18 patients had received antibiotics during the week prior to developing meningitis. Nine (50 per cent) had a chronic, noninfection, underlying illness. Diagnostic or surgical procedures involving the neuraxis or adjacent structures preceded the development of meningitis in 10 of the 18 patients (56 per cent). Only 6 of the 18 patients survived their infection. Prompt recognition, diagnosis, and therapy of hospital-associated meningitis in high-risk patients may reduce the significant mortality.
