What is a catheter-related risk factor for bloodstream infections?

The duration of catheter use is a significant risk factor for catheter-related bloodstream infections (CRBSIs). Prolonged catheterization increases the likelihood of biofilm formation on the catheter's surface, which can harbor bacteria and lead to infections. The longer a catheter is in place, the greater the chance that it may become contaminated and consequently lead to an infection.

While factors such as antibiotic usage, length of hospital stay, and the presence of fever may influence patient outcomes or reflect underlying issues, they do not directly relate to the mechanical and biological factors associated with catheter use as clearly as duration does. Thus, understanding that the length of time a catheter is in place can directly contribute to the development of bacteria and infections underscores the importance of catheter management protocols that aim to minimize catheter duration wherever possible to reduce the incidence of CRBSIs.
