Staphylococcus aureus bloodstream infection in a Chinese tertiary-care hospital:A single-center retrospective study

To the Editor:Despite major advances in medical care,the incidence and mortality of bloodstream infection(BSI)remain high,which is still a global public health challenge.BSI can be caused by various microorganisms,and the most common organisms are Escherichia coli,Klebsiella pneumoniae,and Staphylococcus aureus(S.aureus),according to the China Antimicrobial Surveillance Network(CHINET).[1]S.aureus is the third most common cause of BSI,which is associated with shortterm mortality rates of 15–30%,long-term excess mortality,and increased healthcare costs.At present,there are many studies on Gram-negative bacteremia but relatively few on S.aureus bloodstream infection(SA-BSI),especially in China.With the occurrence of new treatments and clinical conditions,such as aging and extensive antibiotic resistance,it is necessary to reanalyze the clinical characteristics and prognosis of SA-BSI.
