Brief Summary

Sepsis is a disruption of homeostasis in the human body in response to bloodstream infection and is associated with a high risk of mortality.

Worldwide, sepsis is affecting approximately 30 million people and resulting in six million deaths.

Blood culture is a specific blood sample used to identifying microbial agent (bacterium or yeast) and determine the sensitivity of these microorganisms to antibiotics and antifungals.

Any delay in identifying the microorganism and/or determining the AST (antibiotic susceptibility testing) has a direct impact on the administration of appropriate antibiotic treatment and, consequently, on mortality of the patient. The faster the diagnosis, the faster the antibiotic treatment will be adapted, the higher the survival rate/probability of patients, and the lower the ecological impact.

In routine, clinical microbiology laboratories currently use 2 automatized techniques: MALDI-TOF MS® for microorganisms identification and VITEK2® method for AST determination.

Based on a proteomic approach, the IDBIORIV method is a rapid method (90 minutes) in comparison of current methods (24/48 hours) able to identifying a large panel of 113 pathogens and determine the antibiotic resistance profile of 49 species for 4 classes of antibiotics (Beta-lactams, Aminosides, Glycopeptides, Colistin).

The main objective of this study is to evaluate the performance of the IDBIORIV method in pathogen identification and antibiotic susceptibility testing in comparison with current methods of analysis of positive blood cultures used at the microbiology laboratory of the Hospices Civils de Lyon, in a real clinical situation, over a 2-year period.

Primary Outcome Measures
NameTimeMethod
The IDBIORIV method will be compared with the current routine methods present in the Hospices Civils de Lyon. The sensitivity and specificity of the IDBIORIV method will be evaluated using AST results. Reference technique = Vitek 2® bioMérieux24 Hours to 48 Hours after inclusion

The performance of the IDBIORIV method for in vitro diagnosis of antibiotic-resistant/susceptible status will be evaluated for each "species-antibiotic" pair and "species-antibiotic group" of interest.

Sensitivity will be calculated as the proportion of pairs diagnosed as resistant using the IDBIORIV method among pairs diagnosed as resistant using AST.

Specificity will be calculated as the proportion of pairs diagnosed as sensitive with the IDBIORIV method among pairs diagnosed as sensitive with AST.

The IDBIORIV method will be compared with the current routine methods present in the Hospices Civils de Lyon. The sensitivity and specificity of the IDBIORIV method will be evaluated using the Identification (ID) results of a positive blood culture for a24 Hours to 48 Hours after inclusion

Reference technique used = Vitek MS ® (MALDI-ToF) bioMérieux.
