Patient selection. BC, blood culture; FUBC, follow-up BC. If a microorganism of the same species as the initial one was detected in at least one pair of FUBCs, the case was classified as FUBC positive. Conversely, if disparate species were identified in the FUBC, the episode of bacteremia was deemed to be a novel occurrence. The single counts represent the number of BCs itself, and the episodes represent a series of bloodstream infection episodes. ※1663 single counts, including second and subsequent positive BCs in cases of persistent bacteremia and second and subsequent positive BCs in cases in which FUBC detected a different strain than the first BC.
