Abstract

Background: The diagnosis of urinary tract infection (UTI) in the pediatric field remains a topic of debate. In 2011, the American Academy of Pediatrics (AAP) introduced new guidelines for the diagnosis of UTI in patients 2–24 months old. However, concerns were raised regarding these guidelines. Methods: This is a retrospective data extraction study that included patients 0–6 months of age who were examined in the pediatric emergency department between 2016 and 2021 and had a urine culture. For each patient, we recorded the diagnosis documented in the medical records, the diagnosis based on the AAP and Israeli guidelines, and the diagnosis according to our 2 proposed protocols. We then compared the percentage of UTI diagnoses according to each diagnostic guideline. Results: A total of 1432 patients under the age of 6 months underwent urine culture testing during the study period. A total of 83 (5.81%) of these patients were diagnosed with UTI according to the AAP guidelines, 184 of the patients (12.8%) were diagnosed with UTI according to the Israeli guidelines, 102 (7.1%) and 109 (7.6%) of the patients were diagnosed with UTI according to our first and second proposed guidelines, respectively. Conclusions: We propose a new diagnostic method (guidelines II) that is suitable for patients older than 2 months, with obligatory criteria of abnormal urine test and a lower threshold for the colony count required for diagnosis compared to the AAP guidelines.
