Outpatient management of selected young febrile infants without antibiotics.

Objective: To analyse the outpatient management of selected febrile infants younger than 90 days without systematic lumbar puncture and antibiotics.

Methods: A prospective registry-based cohort study including all the infants ≤90 days with fever without a source (FWS) who were evaluated in a paediatric emergency department (ED) over a 7-year period (September 2007-August 2014). We analysed the outcome of those infants with low-risk criteria for serious bacterial infection (SBI) managed as outpatients without antibiotics and without undergoing a lumbar puncture.
