Purpose. Blood culture contamination can compromise quality of care and lead to unnecessary antibiotic exposure and prolonged length of hospitalization. Microbiology laboratories typically track blood culture contamination rates and can provide data to assist in reducing contamination rates.
Apr 30, 2020 · We present a summary of performance improvement (PI) interventions provided by four hospital systems and common factors that contributed to decreased blood culture contamination (BCC) rates.
Various studies show that the contamination rate ranges between 0.6-6% (2-4); it depends upon the sample collection method and processing in the laboratory. The benchmark of blood contamination rate is <3%, as proposed by the Clinical Laboratory Standard Institute (CLSI) (5).
Dec 5, 2023 · Preventing adult blood culture contamination: a quality tool for clinical laboratory professionals protect patients during the diagnostic process by monitoring adult blood culture contamination (BCC) rates.
While the median adult inpatient contamination rate was 2.5%, some organizations had a rate of less than 1.0%, while for other organizations, more than 5.0% of their blood cultures were contaminated.
Sep 1, 2018 · On the basis of prevalence data, it has been recommended that BC contamination (BCC) rates should not exceed 3% of BCs performed, which is considered the standard benchmark [5].
Apr 3, 2018 · Blood culture (BC) remains the reference standard for the diagnosis of bloodstream infections (BSIs), but contaminations represent up to 50% of positive BCs [1,2].
Standards Institute (CLSI) overall blood culture contamination rates should not exceed 3% [1,2], however reported contamination rates in hospitals vary widely ranging from 0.6% to 12.5%, with the highest rates associated with emergency department settings [3,6–9,11,13–20]. One study reported a 26% contamination rate in pediatric outpatients ...
When only one blood culture set is collected out of the two - three recommended sets this is called a single-set blood culture. A single-set blood culture in a 24-hour period is not an adequate volume of blood to make a bacteremia diagnosis. (May lead to false negatives). Single-Set Blood Culture Rate The total number of single-set blood cultures
Peripheral blood culture contamination (BCC) can lead to an initiation of unnecessary antimicrobial treatment, further laboratory tests, increased length of stay, and increased costs. This study describes a 12-month quality improvement (QI) program to reduce the BCC rate in a neonatal unit by 50%.
