Background: Skin colonization of microorganisms in blood cultures (BCs) are generally considered clinically non-significant and can be the source of a true infection, particularly in immunosuppressed patients.
Objectives: To study the epidemiology and risk factors for bacteremia caused by contaminants.
Methods: This retrospective, descriptive study is based on adult BCs collected (2004-2013) and categorized as positive (True bacteremia [TrueB] or contamination) or negative.
