[Nosocomial urinary tract infections in the geriatric hospital - pathogen spectrum and resistancies]

We examined 834 isolates of urinary cultures (26 fungi and 808 isolates from 28 bacteria) in an academic geriatric teaching hospital for microbial spectrum and resistance analysis. Of the bacteria, 90% were associated to ten species. Detection rate of MRSA and ESBL was 1%, detection rate for pseudomonas aeruginosa, proteus species, coagulase negative staphylococci and klebsiella species were higher than in an university clinic (p < 0.001). Resistency rates were high for the 10 most frequent bacteria: 53.3% of cross-tabulations between bacterium and antibiotic agent (sulfamethoxazol-trimethoprim, amoxicillin-clavulanate, ciprofloxacin, moxifloxacin, cefuroxim, imipenem) showed resistency rate higher than 10%. We assume that specific factors of geriatric sample taking have an impact to our 2-year resistogram results. It is necessary to combine data analysis from comprehensive geriatric assessment and microbiological methods.
