CRBSI stands for which of the following?

• A. Catheter-Related Bloodstream Infection
• B. Catheter-Related Bacteremia and Sepsis
• C. Central Retention of Bloodstream Infection
• D. Catheter-Related Bloodstream Illness

Answer: (A)

CRBSI stands for Catheter-Related Bloodstream Infection, the term used for a bloodstream infection in a patient with an intravascular catheter where the catheter is the most likely source. This wording precisely reflects the relationship between the catheter and the infection, which is why it’s the correct expansion. The other options either change the standard terminology or use terms that aren’t recognized in this context (for example, suggesting bacteremia and sepsis, or a non-existent “central retention” phrase). In practice, recognizing this term helps guide management, including evaluating the catheter as the source and determining appropriate antibiotic therapy.
