Insertion of an antimicrobial catheter, either silver alloy or antimicrobial coated, is recommended for patients with short-term indwelling catheterization. There is insufficient evidence to recommend their use in patients managed by long-term indwelling catheterization. Selection of smaller French sizes for short- or long-term catheterization is thought to improve comfort and reduce CAUTI risk, but further research is needed to substantiate these best practice recommendations.
