Podcast # 432: Hunting for UTIs

Author: Michael Hunt, MD

Educational Pearls:

  • As many as 20% of women in assisted living have asymptomatic bacteriuria
  • This can present a diagnostic conundrum when seeing these patients in the emergency department, particularly for altered mental status and deciding whether to treat
  • True diagnosis of UTI in the emergency department is difficult as true diagnoses required culture results and repeated positive samples
  • Procalcitonin is an emerging biomarker that may be helpful in determining the presence of infection
