2D.5.2D.7.Further research is needed on the benefit of spatial separation of patients withurinary catheters to prevent transmission of pathogens colonizing urinary drainagesystems. (No recommendation/unresolved issue)When performing surveillance for CAUTI, consider providing regular (e.g., quarterly)feedback of unit-specific CAUTI rates to nursing staff and other appropriate clinicalcare staff. (Category II)Q3: What are the best practices for preventing UTI associated withobstructed urinary catheters?The available data examined the following practices:1. Methods to prevent/reduce encrustations or blockage2. Catheter materials preventing blockageFor this question, available relevant outcomes included blockage/encrustation. We did not finddata on the outcomes of CAUTI. The evidence for this question consists of 1 systematic review, 2772 RCTs, 278,279 and 2 observational studies. 280,281 The findings of the evidence review and thegrades for all important outcomes are shown in Evidence Review Table 3.Q3.1. Methods to prevent/reduce encrustations or blockageLow-quality evidence suggested a benefit of acidifying solutions or oral acetohydroxamic acid inpreventing or reducing catheter encrustations and blockage in long-term catheterizedpatients. 277,278,280,281 No differences were seen with daily catheter irrigation with normal saline.Q3.2. Catheter materials preventing blockageLow-quality evidence suggested a benefit of silicone over latex or Teflon-coated catheters inprevention or reducing catheter encrustations in long-term catheterized patients who were proneto blockage. No differences were seen with different materials in patients considered “nonblockers.”279Evidence Review Table 3. What are the best practices for preventing UTI associatedwith obstructed urinary catheters?3.1. Further research is needed on the benefit of irrigating the catheter with acidifyingsolutions or use of oral urease inhibitors in long-term catheterized patients who havefrequent catheter obstruction. (No recommendation/unresolved issue)3.2. Silicone might be preferable to other materials to reduce the risk of encrustation inlong-term catheterized patients who have frequent obstruction.
