title: Hospital-acquired neonatal bacterial meningitis: the impacts of cefotaxime usage on mortality and of amikacin usage on incidence.
abstract: All cases of bacterial meningitis in the neonatal unit at King Edward VIII Hospital, Durban for the period 1 January 1981 to 31 December 1987 were reviewed. In particular, we looked at the impact of cefotaxime on mortality rates and amikacin on the incidence of hospital-acquired Gram-negative bacillary (GNB) meningitis. Klebsiella was found to be the commonest cause of neonatal meningitis, followed by Escherichia coli and Streptococcus agalactiae. Eighty-four per cent of all cases of GNB meningitis presented more than 3 days after birth, with the vast majority being caused by gentamicin-resistant Klebsiella. A decline in the incidence of meningitis from 1.27/1000 live births in 1981 and 0.95/1000 for the period 1981-1986 to 0.22/1000 live births in 1987, with no cases of Klebsiella meningitis being seen in that year, coincided with the exclusive use of amikacin as the parenteral aminoglycoside in place of gentamicin in the unit after August 1986. The initial decline in the incidence of meningitis from 0.93/1000 in 1985 to 0.46/1000 in 1986 was attributed to the introduction in 1985 of strict hand disinfection measures to prevent cross-infection in the unit. The case mortality rate (CMR) fell from 0.65 for the period 1981-1984 to 0.42 for the period 1985-1987, and we believe this was largely a result of the introduction of cefotaxime in 1984 as first-line therapy for GNB meningitis, together with better patient care facilities.(ABSTRACT TRUNCATED AT 250 WORDS)
