Summary

Staphylococcus aureus is a frequent cause of primary or secondary bacteremia. It is also responsible for many cases of infective endocarditis, for which the therapeutic management is specific. The frequency of infective endocarditis among Staphylococcus aureus bacteremias varies between 2.7% and 23.4%. Many factors associated with the risk of developing endocarditis in patients with S. aureus bacteremia have been described. Two parameters of potential interest remain excluded from this work: blood culture growth time, a marker of bacterial inoculum, and the presence of bacteriuria, which is common during bacteremia. The objective of this study is to evaluate the interest of these two parameters in the prediction of the presence of endocarditis during S. aureus bacteremia. Investigators will conduct a retrospective study including all patients managed for Staphylococcus aureus bacteremia and in whom a urine culture was performed. The primary objective is to describe the factors associated with the occurrence of endocarditis in patients managed for S. aureus bacteremia and who received a urine cytobacteriological examination (UCE). The secondary objectives are: to evaluate the factors associated with the occurrence of S. aureus bacteriuria in patients with S. aureus bacteremia and to evaluate the risk factors for mortality in patients managed for S. aureus bacteremia.
