This episode discusses the implications of the PECARN Febrile Infant Rule for managing febrile infants in the emergency department.

Traditionally, a fever in this age group has meant an automatic “full septic workup,” including the dreaded lumbar puncture (LP). But times are changing. We sit down with experts Dr. Nate Kuppermann and Dr. Brett Burstein to discuss a landmark JAMA study that suggests we might finally be able to safely skip the LP in many of our tiniest patients. The Study: A Game Changer for Neonates Our discussion centers on a massive international pooled study evaluating the PECARN Febrile Infant Rule specifically in infants aged 0–28 days. While previous guidelines were conservative due to a lack of data for this specific age bracket, this study provides the evidence we’ve been waiting for. The Cohort: A large pool of infants across multiple countries. The Findings: The PECARN rule demonstrated an exceptionally high negative predictive value for invasive bacterial infections. The Big Win: The rule missed zero cases of bacterial meningitis. Defining the Danger: SBI vs. IBI The experts break down why we are shifting our terminology and our clinical focus…
