RISK FACTORS ASSOCIATED WITH URINARY TRACT INFECTION IN GERIATRIC AND ITS MICROBIOLOGIC CHARACTHERISTICS

Abstract

Background : Urinary Tract Infections(UTI) is a general understanding to describe invasion of microorganism in urinary tract. The severity of any functional disability, nature of underlying illnesses, anatomic or physiologic abnormalities of the genitourinary (GU) tract, and use of indwelling bladder catheters determine the types of organisms and chronicity of bacteriuria. Purpose : To analyze factors which associated with Urinary Tract Infections in geriatric patients. Methods : Observational retrospective study conducted by reviewing medical record on 2004 of geriatric patients in Dr.Kariadi Hospital. Independent variables consist of sex, catheterization, initial antibiotics, DM and urine stasis. Dependent variable is geriatric patients who are diagnose as UTIs patients based on urine culture result. Statistic analysis is conducted with descriptive analysis and logistic regression using SPSS 13.00 for windows. Results : Sex and catheterization (p<0.05) associated as the risk factors of UTIs in geriatric patient. Intial antibiotics, diabetes mellitus and urine stasis (p≥0.05) were not significant as risk factor of UTIs in geriatric patients. The pattern of microorganism was as follows, Eschericia coli(46.9%), Enterobacter aerogenes(27.1%), Staphylococcus epidermidis(10.4%), Pseudomonas aeruginosa(9.4%), yeast cell(3.1%), Staphylococcus aureus(2.1%) and Candida sp(1.0%). E.coli still be the most prevalent microorganism. Staphylococcus epidermidis should be considered as contamination. The sensitivity test shown that E.coli had antibiotic sensitivity to meropenem(100%), vancomycin(100%) and cefepim(92.9%). Conclusion : Sex and catheterization associated with UTIs in geriatric patients. Initial antibiotics, DM and urine stasis do not associated with UTIs in geriatric patients. Keywords : Urinary Tract Infections, geriatric patients.
