Today, evidence-based clinical data to document the yield of this strategy deserve to be improved and a large multicenter randomized trial is required to decipher the pro and cons of both strategies of BC collection for the diagnosis of BSIs and infective endocarditis.
Guidelines for evaluation of new fever in critically ill adult patients: Bottles are usually incubated for a maximum duration of 5—7 days Lamy and Seifert, ; Baron et al.

It should be surveyed through systematic program, either internal or external to the microbiology lab, and should at least include the proportions of solitary BC, and of adequately filled BC bottles Schifman et al.

The contamination rate per draw has been estimated at 0. In most cases of positive BCs due to contaminants, only one or two of the four bottles turned positive, and the interpretation of positive BCs with a microorganism of questionable significance was not more difficult than with the multi-sampling strategy Arendrup et al.
Terms, fees and membership levels Hence, the median total volume of blood inoculated will necessarily be greater; vi the single-sampling strategy should enable early initiation of empirical antibiotic treatment when indicated e. The consequences of BC contamination and false positives, although poorly studied, are not trivial, as they may lead to longer hospital stays, useless prescription of antibacterial or antifungal agents, additional investigations e. Bloodstream infections BSIs represent a growing public health concern, with an estimated burden of 1, episodes of BSI each year in Europe, andattributable deaths Goto and Al Hasan, The types and compositions of resins, the type of antibiotics and the MICs of the test strains may account for the differences in neutralization performance Mitteregger et al.
We performed a systematic literature review on clinical and technical issues related to blood collection, as well as interpretation of BCs, in adult patients suspected of BSI. Effects of volume and periodicity on blood cultures. Improvement of BCs bottle filling would require enhanced training of phlebotomists, including systematic visual inspection of bottle filling at the bedside van Ingen et al.
On the opposite, a 6 bottle-collection of blood at once totalizing 35—42 mL ensured an efficient diagnosis of bacterial BSI with an optimized specificity Lamy et al.
While both sampling strategies i. The new manual is based upon the original French manual, but has been updated and adapted for Europe. Only slight improvements in the performances have been achieved over the last 15 years e. Although studies have shown that contamination rates are lower for BCs drawn from newly inserted catheter using a sterile manusl protocol Levin et al.
The main parameter associated with false-negative signal is the pre-incubation delay, which is the time difference between the time point of bottle loading in the BC incubator and the time point of bottles filling. Find out mmanual ESCMID’s organizational structure, its governing regulations as well microbilogy collaborations with other organizations.
Chest— Overall, three continuous-monitoring automated BC systems are available in Published online May On the other hand, BC bottles are inoculated with more than 10 mL of blood in 7. In such a procedure, the detection depends on the bacterial density at time of samplings, and not all samples will turn positive.
Other escjid-sfm impacts of the single-sampling strategy remain to be measured, including patient comfort e. Limitations Firstly, getting a sufficient volume of blood to fill 6 bottles from a single venipuncture may be difficult, particularly in the elderly, and in patients with shock.

Prolonged incubation and escmid-ssfm subculturing do not increase recovery of clinically significant microorganisms from standard automated blood cultures. Optimal testing parameters for blood cultures.
Sections of this page. A multi-interventional study that included education of healthcare workers to avoid the sampling of BCs from central intravenous lines, documented simultaneous decreases in i the proportion of BCs obtained from central lines from Rules for interpretation of positive BC results, and distinction between BSI and contamination, differ with the single-sampling strategy, as the information given by the proportion mlcrobiology positive BC sets at different times cannot be used.
Of note, since Washington’s seminal works Washington,the recommended volume of esmid-sfm to be cultured gradually increased over decades.

D Raoult, G Cornaglia The principles of microbiological work and good laboratory practices: In addition, solitary BC makes it more difficult to distinguish contaminants from pathogens.
Several studies reported rates of solitary BC per center between 10 and Generally, in adults with a suspicion of BSI, 2—4 BC sets should be obtained in the evaluation of each septic episode Baron et al.
