Catheter care statistics at a glance
Catheter care is one of those hospital topics where small process changes can move very large outcome numbers. The dataset behind these catheter care statistics shows a consistent pattern: catheter use is common, infection risk rises quickly with time, and targeted prevention programs can reduce harm materially.
Fast facts
- About 75% of hospital UTIs are associated with a urinary catheter (CDC Clinical Safety page).
- 15%-25% of hospitalized patients receive urinary catheters during their stay (CDC Clinical Safety page).
- In acute care hospitals, UTIs account for more than 30% of reported infections (CDC CAUTI Background).
- The incidence of bacteriuria with an indwelling urinary catheter is 3%-7% per day (CDC Indwelling Urinary Catheter Culture Stewardship).
- Nearly 100% of patients with urinary catheters will have bacteriuria after one month (CDC Indwelling Urinary Catheter Culture Stewardship).
Those five figures explain why catheter care is not a narrow clinical detail. It is a daily infection-prevention workflow that touches placement decisions, line maintenance, removal timing, documentation, and unit-level accountability.

What catheter care statistics say about risk
The strongest signal in the dataset is that catheter-associated infection risk rises fast and stays high if the device remains in place. That shows up in both prevalence-style measures and infection-rate measures.
Big number: Nearly 100% bacteriuria after one month (CDC Indwelling Urinary Catheter Culture Stewardship). That single figure makes duration one of the most important variables in catheter care.
Another key benchmark is the daily risk gradient. The dataset places bacteriuria incidence at 3%-7% per day with an indwelling urinary catheter (CDC Indwelling Urinary Catheter Culture Stewardship). Even without any additional assumptions, that range explains why day-by-day reassessment matters.
Why duration dominates the discussion
The data point below is the practical reason catheter care programs focus so much on early removal:
- 15%-25% of hospitalized patients receive urinary catheters during their stay (CDC Clinical Safety page).
- Once present, the device is associated with a growing infection burden over time rather than a flat risk profile (CDC Indwelling Urinary Catheter Culture Stewardship).
Put differently, catheter use is common enough to matter at the population level, but infection risk increases enough over time to matter at the bedside level too.
At a glance
| Measure | Statistic | Source label |
|---|---|---|
| Hospital UTIs linked to catheters | 75% | CDC Clinical Safety page |
| Hospitalized patients receiving catheters | 15%-25% | CDC Clinical Safety page |
| Daily bacteriuria incidence | 3%-7% per day | CDC Indwelling Urinary Catheter Culture Stewardship |
| Bacteriuria after one month | Nearly 100% | CDC Indwelling Urinary Catheter Culture Stewardship |
| UTI share among acute care infections | More than 30% | CDC CAUTI Background |
Hospital and long-term care catheter use
Catheter care statistics also show that this is not only an ICU problem. The dataset includes acute care hospitals, non-ICUs, and long-term care facilities, which is useful because the use pattern changes across settings but the prevention logic stays similar.
In long-term care facilities, urinary catheter prevalence is about 5% (CDC CAUTI Background). That 5% corresponds to approximately 50,000 residents with catheters at any given time (CDC CAUTI Background). So even a seemingly low prevalence rate still translates into a very large resident count.
Setting-level takeaways
- Acute care hospitals see a substantial share of infections tied to catheter use.
- Long-term care facilities have lower prevalence, but the resident count is still large because the underlying population is large (CDC CAUTI Background).
- Prevention needs to be operationalized differently by unit type, but the underlying risk logic remains the same.
The 2024 WHO catheter-use guidance also broadens the picture beyond urinary catheters. WHO estimated that up to 70% of all inpatients require a catheter inserted into a peripheral vein or artery during hospitalization (WHO 2024 catheter-use guidance). That does not replace urinary catheter data, but it does reinforce that catheter-related workflows are a core part of inpatient care rather than a niche specialty task.
CAUTI rates, pathogens, and burden
The dataset gives several ways to measure catheter-associated urinary tract infection burden, from infections per 1,000 catheter-days to pathogen mix and preventability. Together, those measures show both the scale of the problem and where interventions can make a difference.
Core rate benchmarks
A CDC background figure places pooled mean CAUTI rates in NHSN acute care hospitals in 2006 at 3.1-7.5 infections per 1,000 catheter-days (CDC CAUTI Background). That rate range is a useful reference point because it sits alongside later intervention studies and more recent surveillance figures.
The CDC 2025 CAUTI training slide deck reported a CAUTI SIR of 0.62 across general acute care hospitals in 2023 (CDC CAUTI Training 2025). That same source says the 2023 SIR was 38% below the 2015 national baseline (CDC CAUTI Training 2025). It also reported 17,370 CAUTIs in general acute care hospitals in 2023 (CDC CAUTI Training 2025).
One useful way to read those figures is together:
- The ratio shows relative progress against baseline.
- The absolute count shows the remaining burden.
- The hospital context matters because the same rate can still generate a large case load at national scale.
Pathogen mix in reported CAUTIs
| Pathogen | Share of cases | Source label |
|---|---|---|
| Escherichia coli | 21.4% | CDC CAUTI Background |
| Candida spp | 21.0% | CDC CAUTI Background |
| Enterococcus spp | 14.9% | CDC CAUTI Background |
| Pseudomonas aeruginosa | 10.0% | CDC CAUTI Background |
| Klebsiella pneumoniae | 7.7% | CDC CAUTI Background |
| Enterobacter spp | 4.1% | CDC CAUTI Background |
The pattern here is important because it shows CAUTIs are not dominated by one organism. That means catheter care policies need to support broad infection prevention, not just narrow organism-specific concerns.
Preventability and cost
The dataset estimates that 17%-69% of CAUTIs may be preventable with recommended infection control (CDC CAUTI PDF). That is a wide range, but even the low end suggests a substantial opportunity if implementation is strong.
Cost is another reason these numbers matter. The CDC 2025 CAUTI training slide deck reported an average incremental cost of $9,807 per CAUTI (CDC CAUTI Training 2025). It also reported $7,337 for an ICU CAUTI and $5,439 for a non-ICU CAUTI (CDC CAUTI Training 2025).
Those values make catheter care a financial issue as much as a clinical one. Preventing even a small number of cases can avoid both direct treatment burden and the operational spillover that comes with preventable infection.
What prevention programs changed
The strongest part of the dataset is the before-and-after evidence. Several interventions reduced CAUTI rates, device use, or both. That matters because it shifts catheter care from a theoretical quality issue to a measurable operational lever.
National program results
A national CAUTI prevention program study collected data from 926 units across 603 hospitals in 32 states, the District of Columbia, and Puerto Rico (A Program to Prevent CAUTI in Acute Care). Of the 926 units, 59.7% were non-ICUs and 40.3% were ICUs (A Program to Prevent CAUTI in Acute Care).
The study found:
- Unadjusted CAUTI rate decreased from 2.82 to 2.19 infections per 1,000 catheter-days (A Program to Prevent CAUTI in Acute Care).
- Adjusted CAUTI rate decreased from 2.40 to 2.05 infections per 1,000 catheter-days (A Program to Prevent CAUTI in Acute Care).
- Adjusted incidence rate ratio was 0.86 with 95% CI 0.76-0.96 (A Program to Prevent CAUTI in Acute Care).
- Among non-ICUs, catheter use decreased from 20.1% to 18.8% (A Program to Prevent CAUTI in Acute Care).
- Among non-ICUs, CAUTI rates decreased from 2.28 to 1.54 infections per 1,000 catheter-days (A Program to Prevent CAUTI in Acute Care).
- Non-ICU CAUTI incidence rate ratio was 0.68 with 95% CI 0.56-0.82 (A Program to Prevent CAUTI in Acute Care).
The same study also found significant heterogeneity between ICU and non-ICU changes in catheter use (P=0.004) and CAUTI-rate changes (P=0.001) (A Program to Prevent CAUTI in Acute Care). That is a reminder that intervention effects are not uniform across care settings.
Single-program examples with large reductions
Another bundled critical-care model study reduced CAUTIs from 53 in 2013 to 9 in 2017 (Bundled care model study). That study reported an 83% reduction in CAUTIs and a 33.8% fall in Foley catheter utilization (Bundled care model study).
A computerized feedback and nurse-directed protocol study reported an 81% reduction in device use and a 73% reduction in nosocomial CAUTI (Prevention of nosocomial CAUTI study). In the same study, CAUTI rates fell from 36 to 11 per 1,000 catheter-days (Prevention of nosocomial CAUTI study).
An educational program plus daily checklist study provides another clear step-down pattern:
| Phase | Catheter utilization | CAUTI incidence density | Source label |
|---|---|---|---|
| Phase I | 73.1% | 14.9 per 1,000 catheter-days | Educational program study |
| Phase II | 74.1% | 7.3 per 1,000 catheter-days | Educational program study |
| Phase III | 54.9% | 3.8 per 1,000 catheter-days | Educational program study |
| Phase IV | 45.6% | 1.1 per 1,000 catheter-days | Educational program study |
That table is useful because it shows a dual effect: utilization fell and infection density fell. In other words, better catheter care was not just about cleaner maintenance. It also reflected less device exposure.
Catheter care benchmarks by study
The dataset includes several benchmark studies that can help readers compare intervention intensity and outcome size. These do not prove one intervention is universally best, but they do show the size of change that well-executed programs can generate.
Comparative snapshot
| Study or setting | Outcome | Result | Source label |
|---|---|---|---|
| National acute-care prevention program | Adjusted CAUTI rate | 2.40 to 2.05 per 1,000 catheter-days | A Program to Prevent CAUTI in Acute Care |
| Bundled critical-care model | CAUTI count | 53 to 9 | Bundled care model study |
| Computerized feedback and nurse-directed protocol | Nosocomial CAUTI | 73% reduction | Prevention of nosocomial CAUTI study |
| Educational program with daily checklist | CAUTI incidence density | 14.9 to 1.1 per 1,000 catheter-days | Educational program study |
| Silver-coated catheter study | CAUTI incidence | 6.4 vs 9.4 per 1,000 catheter-days | Silver alloy and hydrogel-coated catheter study |
Device and material findings
The silver-coated catheter study is useful because it isolates a product comparison rather than a broad process bundle. It recruited 306 patients and recorded 4,352 catheter-days in the silver-coated group and 7,474 catheter-days in the conventional group (Silver alloy and hydrogel-coated catheter study).
The study found CAUTI incidence of 6.4 per 1,000 catheter-days in the silver-coated group versus 9.4 per 1,000 catheter-days in the conventional group (Silver alloy and hydrogel-coated catheter study). It also reported a 31% reduction in CAUTI incidence per 1,000 catheter-days in the silver-coated group (Silver alloy and hydrogel-coated catheter study).
Additional subgroup results showed a 48% reduction in long-term users and a 42% reduction in female patients (Silver alloy and hydrogel-coated catheter study). Mean catheterisation time per person was 17.0 days with silver-coated catheters, 10.8 days with conventional catheters, and 13.6 days in patients who used both catheter types (Silver alloy and hydrogel-coated catheter study).
That spread suggests that material choice may matter, but it should be read alongside clinical context, patient mix, and protocol quality.
Bloodstream-infection-related catheter care evidence
The dataset also includes central-line catheter care findings, which are not urinary CAUTI data but still fit the broader catheter care theme. A multicenter intervention study found femoral vein CVC insertions fell from 12.9% to 9.4% and properly dated dressings increased from 26.6% to 34.4% (Multicenter intervention to prevent catheter-associated bloodstream infections). That study also reduced catheter-associated bloodstream infections from 11.2 to 8.9 infections per 1,000 catheter-days (Multicenter intervention to prevent catheter-associated bloodstream infections).
An 11-year chlorhexidine-dressing study reduced CABSI rates from 1.48 to 0.69 episodes per 1,000 catheter-days and then to 0.23 episodes per 1,000 catheter-days with CHG gel dressings (Sustained reduction study). The same study reported allergic skin reactions of 0.3 per 1,000 device-days for both CHG dressing types (Sustained reduction study).
That last point is important because it gives a more complete picture: prevention gains can coexist with manageable adverse-event rates.
Why the numbers matter operationally
The practical lesson in these catheter care statistics is not just that CAUTIs are harmful. It is that they respond to design choices.
A few themes stand out:
- Exposure matters. The daily bacteriuria range and the near-universal one-month bacteriuria figure show why time with a catheter is such a strong risk driver (CDC Indwelling Urinary Catheter Culture Stewardship).
- Setting matters. ICU and non-ICU results differ, and long-term care has a different prevalence profile than acute care (A Program to Prevent CAUTI in Acute Care; CDC CAUTI Background).
- Process discipline matters. Checklist, feedback, and bundle studies all show large declines in CAUTI rates or device use (Educational program study; Prevention of nosocomial CAUTI study; Bundled care model study).
- Cost matters. An average incremental CAUTI cost of $9,807 is large enough to justify sustained prevention effort (CDC CAUTI Training 2025).
- Prevention is still incomplete. Even with national progress, the 2023 acute-care count of 17,370 CAUTIs shows a meaningful remaining burden (CDC CAUTI Training 2025).
For anyone comparing catheter care benchmarks, the most useful pattern in the data is the repeated pairing of lower utilization with lower infection density. That combination is the clearest signal that catheter care improvements are not just documentation gains or abstract quality improvements. They are measurable shifts in patient exposure and infection outcomes.
