Assessment of Bacteremia in a Large Tertiary Care Hospital in Northern Vietnam: A Single-center Retrospective Surveillance Study.

The clinical analysis of cases of Bacteremia would be valuable. However, thus far, limited data on bacteremia are available in Vietnam. A single-center, retrospective surveillance study was conducted in Bach Mai Hospital, Hanoi, Vietnam from 2009 to 2012. In total, 45,366 blood culture cases 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%. The rate of positive blood culture 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 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 in the present study was higher than that of the Japanese study (9.6 vs. 25.2 and 49.6% vs. 32.8%). The distribution of microorganisms was unique in terms of the relative predominance of Acinetobacter cases. The percentage of cases of healthcare-associated bacteremia may be relatively high.
