In an attempt to reduce costs, the role of Bactec anaerobic blood culture in the detection of bacteraemia and fungaemia in children was evaluated. Results from 3 167 sets of aerobic and anaerobic blood cultures from children admitted to the University Hospital, Kuala Lumpur during a one year period, were analysed. Four hundred and eight (12.9%) sets of blood cultures were positive, of which 348 sets (1 1.0%) from 201 patients were clinically significant. Of the 348 significant positive sets, organisms were isolated on 177 (50.9%) occasions from both aerobic and anaerobic bottles, on 136 (39.1%) occasions from the aerobic bottle only and 35 (10.0%) occasions from the anaerobic bottle only. No strict anaerobes were isolated, but clinically significant isolates recovered from the anaerobic bottle only included Klebsiella pneumoniae, Salmonella species, Enterobacter cloacae, Staphylococcus aureus, coagulase negative staphylococci, Streptococcus pneumoniae and Group B streptococcus. Patients with bacteraemia diagnosed solely by anaerobic culture were distributed evenly across the various paediatric subspecialities. When results from the anaerobic bottles were excluded, the overall isolation rate was reduced from 11 % to 9.9%. Potential financial savings resulting from omission of anaerobic cultures must be balanced against the small number of bacteraemic episodes that could be missed. Undiagnosed bacteraemia may result in increased morbidity and mortality with its own attendant financial implications.
