Screening circumstances and bacteriology of urinary tract infections in the elderly, Vierzon, France

Abstract

Introduction: Urinary tract infections are a major concern mainly in the elderly. This study focused on the circumstances of screening and the bacteriology of urinary tract infections in the elderly.

Study method: This was a cross-sectional, descriptive and analytical study which concerned subjects aged at least 65 years with a urinary tract infection and hospitalized in Vierzon hospital. The variables studied were related to the general characteristics of the patients, the circumstances of screening for the urinary tract infection, the nature of the pathogens and their susceptibility to antibiotics.

Results: The study population consisted of 150 subjects. A female predominance was observed with a sex ratio of 2. The mean age was 84.21 ± 10.20 years. Fever (66%) and pollakiuria (22%) were the main circumstances for screening for urinary tract infection. Escherichia coli was the main cause of infection and was found in 80% of cases. Ampicillin, amoxicillin and ticarcillin were not active on Escherichia coli in 15%, 7.5% and 15% of cases respectively.

Conclusion: Escherichia coli is the main cause of urinary tract infection most often revealed by fever in the elderly and in most cases has good sensitivity to antibiotics.
