| Abstract |
We retrospectively investigated the implementation status and outcomes of blood culture testing at our hospital, which serves as a designated cancer center. The study included 49,755 blood culture specimens submitted from January 2018 to December 2022 over a five-year period. The annual number of specimens during the study period was approximately 10,000. The positivity rate ranged from 8.9% to 10.7%, and the contamination rate ranged from 0.6% to 0.8%. The rate of multiple set collection (excluding the pediatric oncology unit and hematopoietic stem cell transplantation unit) was 92.2% to 94.7%. The breakdown of infections by type revealed catheter related blood stream infections (CR-BSI) as the most common at 23.7%, followed by biliary tract infections at 22.6%. The detection rates of major isolated pathogens were as follows: Coagulase-negative staphylococci (CNS) 24.0%, Escherichia coli 11.6%, Klebsiella pneumoniae 8.4%, Enterococcus spp. 7.8%, and Candida spp. 6.2%. Although data on blood culture testing in specialized cancer institutions are limited, our study highlighted characteristics such as the predominance of CNS and Candida spp. among isolated pathogens. |
