Overdiagnosis of urinary tract infections in elderly patients leads to unnecessary use of antibiotics. Urinary tract infections are one of the most common diseases in the elderly and their incidence increases with age, especially from the age of 60 years[1][5]. According to the World Health Organization, senior age starts from 60 years and the risk increases due to involutional changes in the urinary tract and comorbidities[1]. Women are more frequently affected due to urinary tract anatomy, but from 60 years of age the incidence evens out between the sexes[1][6]. In the elderly, multidrug resistant bacteria such as Proteus, Klebsiella or Pseudomonas predominate, in contrast to the younger where E. coli predominates[1][4]. Complicated forms lead to ascending infection to the kidney and hospitalizations[1][3]. Asymptomatic bacteriuria is common, risk factors include catheters and urinary outflow disorders[4].
