CAUTI Cost Calculator
The CAUTI Cost Calculator estimates your hospital’s costs due to
catheter-associated urinary tract infections (CAUTI), which are the most common form of hospital-acquired infection.
It can be used to estimate both current costs and projected costs after a hypothetical intervention to reduce catheter use, a protocol that involves daily assessment of the need for a catheter.
Try estimating the CAUTI costs for your hospital:
Number of annual adult hospital admissions
Percentage of adult hospitalized patients with indwelling
urinary catheter on any given day (0-100)
Mean duration of urinary catheterization (in days)
Per-person cost of symptomatic urinary tract infection ($)
Per-person cost of bloodstream infection ($)
Percent decrease in catheterization duration caused by intervention (0-100)
Percent decrease in urinary catheter placement caused by intervention (0-100)
If you aren’t sure about your hospital’s numbers, you can leave the fields blank and the calculator will use suggested default values from the literature.
Here’s an example:
For a hospital using all the default values, we get the following results:
For this hypothetical hospital, the current yearly costs due to catheter-related infections are estimated to be $37,869.
After an intervention that reduces catheter duration by 37% and catheter placement by 29% (i.e., 10.7% catheterized instead of 15%), the projected savings are $19,126 (95% interval estimates: $4,626 – $79,075).
Projected savings are also shown for interventions that equally reduce duration and placement (across a range from 0% to 40%).
The CAUTI cost calculator works by combining relevant risk and cost estimates from past research on catheter-associated complications.
Saint (2000) provides estimates of the risk of bacteriuria, symptomatic urinary tract infection (SUTI), and bloodstream infection (BSI), as well as estimates of the costs associated with SUTI and BSI, computed via microcosting techniques. We combine these estimates to produce new estimates of hospital-specific savings across a range of hypothetical interventions that reduce (i) the duration of catheterization and (ii) the proportion of patients with catheters. This dual-component characterization of interventions to reduce CAUTI is similar to that taken in Fakih et al. (2012).
We focus specifically on savings after the estimated reductions in duration from Meddings et al. (2010) and in placement from Fakih et al. (2010).
