Letica-Kriegel AS, et al. - In this retrospective cohort study, researchers investigated how the risk for catheter-associated urinary tract infections (CAUTI) changes over time and assessed whether the time from catheter insertion to CAUTI event varied depending on risk factors (ie, age, sex, patient type [surgical vs medical]) and comorbidities. The study sample consisted of all patients catheterized between 2012 and 2016, including those who did and did not develop CAUTIs. Also included were pediatric and adult patients. Investigators showed the incremental risk of CAUTI associated with each additional day of catheterization using a very large data set, as well as the risk factors that increase the hazard for CAUTI. They found that about 12% of patients who have a catheter inserted for 30 days will develop a CAUTI. Paraplegia, cerebrovascular disease, and female sex increased the chances of CAUTI statistically. Patients with these risk factors, such as women or those with mobility problems, should be given special attention.
