The major modifiable risk factor for catheter-associated urinary tract infection (CAUTI) that is addressed by the 'bladder bundle' intervention is:

• A Systemic antibiotic prophylaxis during catheter insertion
• B Daily urinalysis surveillance with empiric antibiotic treatment of bacteriuria
• C Early removal of urinary catheter when no longer clinically indicated ✓
• D Use of antimicrobial-coated catheters in all ICU patients

Explanation

The most effective CAUTI prevention strategy is avoiding unnecessary catheterisation and removing catheters as soon as they are no longer clinically required. Bladder bundles include: maintaining a closed drainage system, securing the catheter properly, daily review of catheter necessity, and insertion using aseptic technique. Treating asymptomatic bacteriuria (ASB) in catheterised patients is not recommended (except pre-urological surgery and pregnancy) as it does not reduce symptomatic UTI and promotes antibiotic resistance. Antimicrobial catheters show modest benefit only in specific high-risk populations.
