Session 34. Oral Abstracts in Diagnostic Microbiology. No. 132. Detection of Bloodstream Infections in Adults: How Many Blood Cultures are Needed? Session 67. Late Breaker Symposium, Session 86. Oral Abstract Session, Epidemiology
Lee, Weinstein, Mirrett, and Reller reviewed all positive blood cultures (BC) obtained from adult inpatients from November 1, 2004 through December 31, 2005 at Robert Wood Johnson University Hospital and Duke University Medical Center. Medical records of those inpatients were analyzed, and BC, which were felt to represent true infection, were included in the study. Of 248 unimicrobial episodes with at least 4 BC obtained in 24 hours, 73.4 of bloodstream infections (BSI) were detected with the first BC, 89.9 were detected with the first 2 BC, 96.4 were detected with the first 3 BC, and 99.6 were detected with the first 4 BC. Of 181 unimicrobial episodes with 3 BC obtained over 24 hours, 77.3 were detected with 1 BC, 93.9 were detected with 2 BC, and 100 were detected with 3 BC. Of 37 polymicrobial episodes, 94 were detected with 2 BC and 100 were detected with 3 BC. The authors conclude that 4 BC in 24 hours seem to be necessary to detect greater than 99 of BSI.
