Table 5

Cost-benefit evaluation (restricted to direct hospital costs) of the silver-hydrogel catheter

Assumptions of analysis
Proportion of CAUTIs diagnosed clinically 65%
Cost of each diagnosed CAUTI ~$1000a
Added acquisition cost of a silver-hydrogel catheter ~$5
Incremental hospital costs, per 100 catheters:
Using standard urinary catheters
(26 CAUTIs, 17 diagnosed) $17,000
Using silver-hydrogel catheters
(15 CAUTIs, 10 diagnosed) $10,000
Added cost of catheters $500b
Total costs $10,500
Potential savings per 100 catheters $6,500

aBased on studies showing that a diagnosed nosocomial CAUTI adds approximately $1,000 to direct costs of hospitalization (14); CAUTI = catheter-associated urinary tract infection.
bCost of preventing a CAUTI: approximately $71.
