Abstract Background Fever without a source in well appearing young infants remains a challenge in pediatric emergency departments (PEDs). Although evidence-based decision rules exist, limited data are available on how these patients are managed in daily clinical practice. Methods We conducted a multicenter cross-sectional survey among pediatricians working in 20 Italian PEDs. The 22-item questionnaire explored the definition of “well appearing”, clinical assessment, diagnostic workup, use of standardized protocols, antibiotic prescribing, and self-reported competence in managing well-appearing febrile young infants aged 29–90 days. Descriptive statistics and Chi-square tests were used to compare responses by geographic area and physician seniority. Results A total of 273 (response rate 84%) participated in the study. Half of them worked in Northern Italy, and 47% had < 5 years of experience. Standardized protocols were used by 56%, most commonly the Step-by-Step approach (28%) or local institutional guidelines (32%). Criteria used to define “well appearing” were highly heterogeneous. Urine dipstick testing was routinely performed by 80%, with culture obtained based on dipstick positivity in 66%. Inflammatory markers were routinely tested by 58%, and lumbar puncture was reserved for neurologic signs or clinical deterioration (63%). When inflammatory markers were within normal ranges, 67% discharged patients with close follow-up, while 83.5% reported using a conditional approach to antibiotic initiation guided by diagnostic findings (inflammatory markers and/or viral testing), mainly amoxicillin-clavulanate. Regional and seniority-related variability was significant. Conclusions Italian PED physicians show moderate adherence to standardized protocols for managing well-appearing febrile young infants, but there is no shared definition of “well appearing”. These findings underscore the need for harmonized national guidelines and shared definitions to promote evidence-based care.
