The primary logistic model included only admission characteristics; ICU stay/catheter duration was descriptive because exact CAUTI onset dates were unavailable. Skewed biomarkers were summarized with medians, interquartile ranges, and Mann-Whitney tests.</p> <p>Results</p><p>Bacterial CAUTI occurred in 301 patients (9.3%; 95% CI 8.4%−10.4%). Mean ICU stay/catheter duration was 28.3 versus 13.6 days (difference 14.8 days; 95% CI 11.7–17.8), but duration was not interpreted as an independent risk estimate.

Mortality was 49.2% versus 45.9% (risk difference 3.2 percentage points; 95% CI −2.7 to 9.1), and bacterial CAUTI was not associated with death after adjustment for admission characteristics (OR 0.95; 95% CI 0.75–1.22). Female sex (OR 1.48; 95% CI 1.15–1.90), obesity (OR 1.62; 95% CI 1.20–2.19), and COVID-19 (OR 2.16; 95% CI 1.55–3.00) were independently associated. At least one resistance phenotype was recorded in 200 patients (66.4%).</p> <p>Conclusions</p><p>Bacterial CAUTI was associated with a distinct admission profile and longer observed ICU stay/catheter exposure, although causal direction could not be determined.

It was not associated with adjusted in-hospital mortality.</p></div>
