There are a lot of decision support tools out there when it comes to caring for children in the Emergency Department. Urinary tract infections are exceedingly common in febrile children who have not yet been potty trained. UTI Calculator, from the University of Pittsburgh, allows you to plug in risk factors for febrile UTI in children ages 2 to 23 months and get a probability of a urinary tract infection. The factors include:

  • Age < 12 months
  • Maximum temperature ≥ 39 °C (i.e., 102.2°F)
  • History of UTI
  • Female or uncircumcised male
  • Other fever source
  • Duration of fever ≥ 48 hrs

I find that pulling up this website when discussing getting a catheter-obtained urinalysis and culture is an extremely helpful way to discuss risk and probability with parents. I know that many of you are already familiar with how to use this tool – but I wanted to expand the audience as much as possible because it is wonderful.
