Urinary tract infection (UTI) is one of the most prevalent diseases in clinical practice and increases in patients older than 65years compared to middle-aged patients. In order to improve empirical treatment, the etiology and antibiotic sensitivity profile of the most frequent bacteria that produce UTIs in older people have been studied.
Cross-sectional, descriptive and retrospective study in which isolated micro-organisms with significant counts in urine samples from patients with UTI were included. The global etiology and according to sex were analyzed. Only one urine sample per patient and UTI episode was considered.
Regarding the origin of the sample, the highest proportion was in primary care with 4853 urine cultures (51.6% of positive urine cultures), followed by hospital care with 3565 urine cultures (46.4% of positive urine cultures) and 94 urine cultures in nursing homes elderly (2% positive urine cultures). Escherichia coli was the most isolated micro-organism both in the population as a whole (54%) and in each of the analyzed groups. It was observed that E.coli isolated in women was significantly higher than in men (χ, P=.044). Their sensitivity was: 80% fosfomycin and 75% amoxicillin-clavulanic acid.
E.coli continues to be the most frequently isolated micro-organism in UTI. Empirical treatment of UTI in our environment should include fosfomycin or amoxicillin-clavulanic acid, regardless of the health care unit and gender.
