Bottom line:  Best available evidence suggests that tap water can be used to effectively clean genitalia; daily cleaning of the meatal area and early removal of catheters are associated with reduction in CAUTIs.  Some evidence suggests silver-impregnated catheters associated with decreased incidence of bacteriuria.  Evidence does not support use of sealed drainage systems (as a single strategy), adding antibacterial solutions to drainage bags, or routinely changing drainage bags (as opposed to changing only when clinically necessary.)

Review of studies retrieved from Medline and CINAHL and that included adult patients using urinary catheters 1 to 14 days.  Methodologies included first RCTs.  If no RCTs available, then non-randomized studies and before and after studies were included.  Results section describes findings for various types of intervention strategies.
