4.4 Indwelling urinary catheters: catheter selection
For patients using a long-term indwelling urinary catheter, what is the clinical and cost effectiveness of impregnated versus hydrophilic versus silicone catheters in reducing symptomatic urinary tract infections, encrustations and/or blockages?
Why this is important
Long-term indwelling catheters (both urethral and suprapubic) are commonly used in both hospital and community care settings. Long-term catheterisation carries a significant risk of symptomatic urinary tract infection, which can lead to more serious complications. Several different types of impregnated and hydrophilic long-term indwelling catheters on the market claim to be more effective than non-coated catheters, but are also more expensive.
The clinical evidence review for the guideline revealed an absence of evidence for the effectiveness of indwelling catheters over the long term. A comparison of impregnated (for example, with silver), hydrophilic and silicone catheters is needed. The primary outcome measures should be symptomatic urinary tract infections, encrustations, blockages, cost/resource use and quality of life. Secondary outcome measures should include the mean number of days the catheter remains in situ (mean dwell time) and patient comfort
I think that this is really saying that the cost / benefit of coated catheters is yet to be shown. Given the are considerably more expensive than the hydrophilic sort. You would be better off with the supra-pubic sort generally, Dave.
