What does maintaining a closed system in catheter management help prevent?

Maintaining a closed system in catheter management is crucial in preventing infections, specifically catheter-associated urinary tract infections (CAUTIs). A closed system minimizes the exposure of the catheter and its insertion site to environmental pathogens, significantly reducing the risk of microorganisms entering the urinary tract.

When a catheter is in place, it provides a direct pathway for bacteria to enter the bladder, which can lead to infection. By keeping the system closed, barriers are established that hinder bacterial migration. This practice includes using sterile techniques during insertion and ensuring that drainage bags remain closed and secure at all times.

While the other factors listed are important to consider in catheter management, the primary focus of a closed system is indeed infection prevention, as it directly relates to the pathogenic risks associated with catheter use.
