Blood culture contamination was significantly reduced through use of the initial specimen diversion device (ISDD) compared to standard procedures: (2\/904 (0.22%) ISDD vs 16\/904 (1.78%) standard practice, P=0.001).\u00a0 Sensitivity was not compromised: true bacteremia was noted in 65\/904 (7.2%) ISDD vs 69\/904 (7.6%) standard procedure, P=0.41. No needle stick injuries or potential blood borne pathogen exposures were reported. Seventy-three percent of phlebotomists completed a post-study anonymous survey and widespread user satisfaction was noted.<\/p>\n<p>Blood culture contamination is a common and clinically significant problem. False positive blood cultures increase laboratory costs by approximately 20%, are associated with nearly 40% increase in antibiotic charges, are treated with antimicrobials up to one-half of the time, extend the length of hospital stay up to five days and subject patients to the real harms associated with antibiotic exposures such as toxicity, side effects, interactions and emergence of resistance.\u00a0 It is estimated that a contaminated blood culture costs somewhere between $1,000 (1998) and $8,700 (2009) per case.\u00a0 Approximately 30,000,000 blood cultures are performed in the United States each year. If our findings were extended to all blood cultures in the United States, and a midpoint cost of $4,850 was applied, it would result in approximately 467,000 fewer contaminated blood cultures and a cost saving of $2,270,000,000-that\u2019s real money!<\/p>\n<p>Citation:<\/p>\n<p>Rupp ME, Cavalieri RJ, Marolf C, Lyden E.
