Sepsis is a serious health problem with a very high mortality in the ICU. The most important treatment for sepsis is the fastest possible antibiotic therapy. The identification of the pathogen responsible for sepsis is essential to propose an appropriate antibiotic treatment. However, the diagnosis of bacteremia by blood culture requires an average delay of 48 to 72 hours. The new test proposed by OCEAN Dx makes it possible to identify a bacteremia in a few hours. The main objective of the study is to evaluate the performance of the rapid identification test for bacteremia proposed by OCEAN Dx compared to a classic diagnostic strategy using blood cultures.

Sepsis is a worldwide problem. The World Health Organization estimates that around 49 million people suffer from sepsis each year. It is responsible for an unacceptable number of deaths, estimated at around 11 million. The severity of sepsis is not only related to the infection itself, but often to a too late diagnosis and an important heterogeneity in the management of patients. The identification of the pathogen responsible for sepsis is currently based on the positivity of bacteriological samples, particularly blood cultures. However, the diagnosis of bacteremia by blood cultures requires an average delay of 48 to 72 hours, which is not conducive to rapid adaptation of antibiotic therapy. The test proposed by OCEAN Dx offers the identification of a bacteremia in a few hours thanks to the recognition of the bacterial DNA in the patient's blood. The main objective of the study is to evaluate the performance of the rapid identification test for bacteremia offered by OCEAN Dx in comparison with a classical diagnostic strategy using blood cultures.
