In this main episode podcast on ED risk stratification and workup of the febrile infant, recorded at the CAEP 2022 Conference in Quebec City with Dr. Brett Burstein and Dr. Gary Joubert, we answer such questions as: Which febrile infants require lumbar puncture? How accurate is procalcitonin in identifying low risk febrile infants? What is the difference between serious bacterial infection (SBI) and invasive bacterial infection (IBI) and why is this important in the work up of the febrile infant? How do the PECARN, Step-by-Step and Aronson decision tools for identifying febrile infants at low risk for IBI and SBI? Can EM Cases incorporate all these decision tools and the upcoming Canadian Pediatric Society position statement on febrile infants recommendations into one concise algorithm? and many more…

There has been a major paradigm shift in how we work up the febrile infant in the ED recently. Validated decision tools that include procalcitonin have allowed us to safely avoid lumbar puncture, immediate empiric IV antibiotics , and admissions to hospital in a greater proportion of febrile infants than in the past. Gone are the days that every febrile infant less than 60 days of age reflexively get an LP, full septic workup, empiric antibiotics and pediatric consult/admission. We need to slow down and consider the decision tools and an algorithm based on the latest evidence and the upcoming Canadian Pediatric Society position statement on febrile infants that we present here.

Important definitions for the febrile infant

Fever: single temperature >38.0 ℃ rectal

Fever without a source in pediatrics: child <3 years old, who after initial history and physical, do not have an identifiable cause of their fever

SBI: Serious Bacterial Infection – includes urinary tract infection, bacterial meningitis and bacteremia

IBI: Invasive Bacterial Infection – includes only bacterial meningitis and bacteremia

ANC: Absolute Neutrophil Count

Febrile infant low risk decision tools for infants: PECARN, Step-by-Step and Aronson

The choice of which decision tool one uses depends on local availability of procalcitonin.
