Abstract

The clinical analysis of cases of bacteremia is valuable. However, limited data on bacteremia are available in Vietnam. We conducted a single-center retrospective surveillance study at the Bach Mai Hospital, Hanoi, Vietnam between 2009 and 2012. In total, 45,366 blood cultures were analyzed. The number of blood cultures per 1,000 patient-days was 9.59 sets. The percentage of solitary blood culture sets was 49.6%, and the rate of positive blood cultures was 13.9%. The major pathogens isolated in adults were coagulase-negative Staphylococcus species (16.7%), followed by Escherichia coli (6.8%), Streptococcus spp. excluding Streptococcus pneumoniae (3.8%), and Staphylococcus aureus (5.2%). Other major pathogens identified were Klebsiella spp. (4.2%) and Acinetobacter spp. (2.2%). The number of blood cultures per 1,000 patient-days was lower and the percentage of solitary blood culture sets higher than that of a Japanese study (9.6 vs. 25.2 and 49.6% vs. 32.8%, respectively). The distribution of microorganisms was unique in terms of the relative predominance of cases of Acinetobacter bacteremia. The percentage of cases of healthcare-associated bacteremia may be relatively high.
