P-825: Peculiarities of urinary tract infections in hospitalized older patients

摘要

Introduction: Previous studies showed link between certain pathogens of urinary tract infection (UTIs) and gender in hospitalized older patient's. [1]. Effective treatment of UTIs may prevent complications (chronic kidney failure, urosepsis, lethal outcomes) [2]. Methods: In retrospective study we analyzed data of 101 hospitalized older patients in Geriatric department. The inclusion criteria were a positive urine microbiological culture and ICD-10 codes N10, N11, N30. Results: In 101 patients group (the average age was 82 (± 7) years) with UTIs 51.1% of patients suffered from chronic pyelonephritis, 23.8% from chronic kidney disease, 28.7 from stroke, 26.7% from diabetes mellitus and 42.6% from dementia. Urinary incontinence was diagnosed in 62.4% patients. Catheterization of urinary bladder was performed in 30.3% of the patients. Microbiological culture determined 14 different causative agents of UTIs: E. coli was found in 54.5%, K. pneumoniae in 25.7%, E. faecium in 12.9%, P. mirrabilis in 10.9%, E. faecalis in 7.9%, E. cloacae in 5.0%, P. aeruginosa in 4.0%, C. albicans, K. oxytoca each in 2.0%, C. urealyticum, S. liquefaciens, S. aureus, C. freundii, C. diversus each in 1.0% of the samples. In females UTIs are statistically significantly more often caused by E. coli (= 23.348, 2 = 23.348, p = 0.001). In males UTIs are statistically significantly more often caused by P. mirabilis (p = 0.027) and E. cloacae (p = 0.017). Key conclusions: UTI in the Geriatric department is more prevalent in women. The most common risk factors among the patients with UTI were chronic pyelonephritis, dementia, urinary incontinence. Females more often suffer from UTIs caused by E. coli, males—P. mirrabilis ir E. cloacae.
