“…However, the elements of urinalysis may change over time after catheterisation and at different rates in male and female patients [29]. Similar to our results, Gram-negative Enterobacteriaceae are the most common causes of CAUTIs as identified in other studies [8,10,[31][32][33]. Although Escherichia coli was the most isolated microorganism in most studies, K. pneumonia was the most common causative agent in our findings and in 132 another study on ICU patients in Tehran, Iran [34,35].…”

Introduction: Catheter-associated urinary tract infections (CAUTIs) are among the most common nosocomial infections with different clinical and microbiological characteristics. We studied these characteristics in critically ill patients. Methodology: This research was a cross-sectional study conducted on intensive care unit (ICU) patients with CAUTI. Patients’ demographic and clinical information and laboratory data, including causative microorganisms and antibiotic susceptibility tests, were recorded and analyzed. Finally, the differences between the patients who survived and died were compared. Results: After reviewing 353 ICU cases, 80 patients with CAUTI were finally included in the study. The mean age was 55.9 ± 19.1 years, 43.7% were male and 56.3% were female. The mean length of infection development since hospitalisation and hospital stay were 14.7 (3–90) and 27.8 (5–98) days, respectively. The most common symptom was fever (80%). The microbiological identification showed that the most isolated microorganisms were Multidrug-resistant (MDR) Enterobacteriaceae (75%), Pseudomonas aeruginosa (8.8%), Gram-positive uropathogens (8.8%) and Acinetobacter baumannii (5%). Fifteen patients (18.8%) died among whom infections with A. baumannii (75%) and P. aeruginosa (57.1%) were associated with more death (p = 0.005). Conclusions: Although A. baumannii and P. aeruginosa can be the most important pathogens for death, MDR Enterobacteriaceae are still a serious concern as causes of CAUTIs.
