Which factor is associated with higher mortality risk in CAUTI?

• A. Short Duration Of Catheterization
• B. Prolonged Catheterization
• C. No Comorbidities
• D. Younger Age

Answer: (B)

Prolonged catheterization raises mortality risk in CAUTI because the longer the catheter stays in place, the greater the opportunity for bacterial colonization and biofilm formation on the catheter surface. Biofilms harbor pathogens and protect them from antibiotics and the immune system, allowing infection to ascend from the bladder and potentially enter the bloodstream, increasing the chances of sepsis and death. Each additional day of catheterization adds exposure to resistant organisms and intensifies inflammatory damage, so reducing dwell time and removing the catheter as soon as it’s no longer needed minimizes mortality risk.
