Infection Control and Hospital Epidemiology

چکیده
Understanding the origins, treatment, prevention, and outcomes of nosocomial bloodstream infections (BSIs) is of utmost importance because they are one of the most frequent and severe infectious complications of hospitalization and medical care. The outcomes of BSIs may differ depending on patient factors including underlying conditions and immune status; organism factors including virulence and resistance; and treatment factors such as agent and dose used, delay in appropriate therapy, removal of hardware, and associated supportive therapy. This issue of Infection Control and Hospital Epidemiology includes four studies that examine different factors that affect the outcome of nosocomial BSIs. These studies present an opportunity to discuss some methodologic principles in measuring the outcomes of hospital-acquired infections and how methods used in such studies may affect study results.
