What is a key infection-prevention strategy for patients with indwelling catheters?

• A. Minimize catheter use.
• B. Use aseptic technique during insertion.
• C. Remove catheter as soon as clinically possible.
• D. Minimize catheter use, aseptic technique during insertion, and remove catheter as soon as clinically possible.

Answer: (D)

Preventing infections from indwelling catheters hinges on reducing exposure and avoiding introduction of bacteria from the start. The best approach combines three practices: minimize catheter use so the bladder is never exposed longer than needed; use aseptic technique during insertion to prevent introducing organisms into the urinary tract; and remove the catheter as soon as it’s clinically possible to limit the duration of foreign-body colonization. Together, these reduce the overall risk of catheter-associated infections more effectively than any single measure alone. While each element matters, applying all three consistently yields the strongest protection.
