Introduction 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, We focused on the impact of BC collection strategies on their performance for the diagnosis of BSI, as this has not been a major focus in most recent reviews e.
Update on detection of bacteremia and fungemia.
Predicting bacteremia in hospitalized patients. These false-positive bottles require quick handle and re-incubation into the BC system e. Incubation time Bottles are usually incubated for a maximum duration of 5—7 days Lamy and Seifert, ; Baron et al. The differentiation between clinically significant positive BCs i. Authors at launch in The median specificity of positive BCs decreased from 0.
The multi-sampling strategy has been developed, and recommended for more than 40 years, and its practice has been generalized Washington, In addition, solitary BC makes it more difficult to distinguish contaminants from pathogens. Table 3 Quality of bottle filling.
Recent Post by Page. One sample is enough for confidently detecting bacteremia; the overall results would suggest a continuous bacteremia. Control 16— For instance, Wain et al.
Yields were similar over a h period before and after temperature spikes Riedel et al.
Conceived and designed the work: Clinical impact of reducing routine blood culture incubation time from 7 to 5 days. Updated review of blood culture mifrobiology. Given the critical importance of sampling the adequate amount of blood for BC sensitivity, monitoring the volume of blood cultured is a strong quality-assurance requirement Mermel and Maki, ; Schifman et al.
In addition, it has been demonstrated that BCs contamination rates are significantly lower when an antiseptic agent is applied on BC bottle tops before sampling Schifman et al. Similar findings were observed in Arendrup et al. Study Microbbiology Research Funding Pathology 46— Evaluation of positive blood cultures: Generally, in adults with a suspicion of BSI, 2—4 BC sets should be microboology in the evaluation of each septic episode Baron et al.

A comprehensive model to optimize the strategy for diagnosing bacteremia. The most recent studies showed that sampling blood volumes of 20, 40, and 60 mL was associated with sensitivities of As far wscmid-sfm possible, BCs should be obtained before the antimicrobial therapy is initiated. Utility of extended blood culture incubation for isolation of Haemophilus, Actinobacillus, Cardiobacterium, Eikenellaand Kingella organisms: In order to define guideline to differentiate clinically significant bacteria from contaminants with this strategy, a study was conducted between and in Lyon University Escmi-sfm Francewhere the single-sampling strategy has been implemented in Leyssene et al.
According to the local epidemiology, the diagnosis escmid-stm BCNE is based on systematic serological testing for Coxiella burnetii, Bartonella spp. European and French guidelines recommend the use of an alcoholic solution for antisepsis before BC sampling Lamy and Seifert, ; Accoceberry et al.
It has been estimated that 0. A device developed on the new BC system Virtuo bioMerieux provides an automated volume estimation of each bottle based on a photometric detection of liquid level, but, as far as we know, its accuracy has not yet been evaluated in clinical studies. escmud-sfm
Other potential impacts of the single-sampling strategy remain to be measured, including patient comfort e. Indeed, the likelihood of documenting BSIs was not significantly enhanced by collecting blood during temperature spikes. The fertility of the culture media used in these systems is among the highest among broth media available in clinical microbiology. As mxnual varies between studies, concentration range and categories vary.
Only slight improvements in the performances have been achieved over the last 15 years e. This can assist in interpreting positive BC results, although the clinical context, including the presence of intravascular foreign devices, is also of paramount importance for an accurate interpretation of BCs positive for CoNS.

Education of phlebotomy teams improves blood volume in blood culture bottles. Overall, the single-sampling strategy allowed detection of pathogens in blood of 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.
Circulation— Terms, fees and membership levels One limitation of this device is that volume is monitored in batches and not for each bottle individually. When infective endocarditis is suspected but BC remain negative on day 5, some guidelines state that bottles incubation must be prolonged until day 15 or more Mainardi and Ricardo, ; Accoceberry et al.

For optimal recovery, each Fscmid-sfm set should include paired aerobic and anaerobic bottles, the aerobic bottle being filled first. Ezcmid-sfm, each venipuncture required for the multisampling strategy is an additional opportunity for contamination Aronson and Bor, ; Lamy et al.
M Mounier – K Summermatter Microbiology of the health care environment: About the Parity Commission This strategy was developed since the late s, based on the following: This point is pivotal especially as studies on BC transport time have shown that delayed entry negatively impacts on time to positivity from the time point of sampling Ronnberg et al.
Compliance with escmmid-sfm and current caveats An increasing amount of data highlights the pre-analytical deficiencies of BC sampling which may compromise patient management by reducing BCs diagnostic yield Schifman et al. This increase resulted both from the need to develop and accept the concept of culturing larger volumes of blood, and from the study design on which data relied on:
