Insights
New American Academy of Pediatrics guidelines offer evidence-based approaches for febrile infants. These guidelines aim to reduce variability in managing fever in infants aged 8 to 60 days.
Area of Science:
- Pediatrics
- Neonatology
- Evidence-Based Medicine
Background:
- Fever evaluation in infants is historically variable.
- The American Academy of Pediatrics released updated guidelines in August 2021.
- Guidelines address previously healthy, term infants (≥37 weeks gestation) with fever (≥100.4°F or 38°C).
Purpose of the Study:
- To provide evidence-based clinical guidelines for febrile infants.
- To decrease variability in the management of febrile infants.
- To improve outcomes for febrile infants.
Main Methods:
- Focus on management and treatment guidelines for three age groups: 8-21 days, 22-28 days, and 29-60 days.
- Incorporates shared decision-making with families.
- Highlights changes in practice for infants aged 22-28 days and 29-60 days.
Main Results:
- Significant changes in management for infants aged 22-28 days and 29-60 days.
- Cerebrospinal fluid studies may be avoided if initial laboratory work is reassuring.
- Options for monitoring include home or hospital-based care.
Conclusions:
- Updated guidelines aim to standardize febrile infant care.
- Shared decision-making is encouraged for management plans.
- The guidelines promote a more nuanced approach to diagnostic testing and monitoring.
Abstract:
Evaluation and management of the febrile infant has long been an area of variability. Recent guidelines were released by the American Academy of Pediatrics in August 2021 to help provide evidence-based clinical guidelines to decrease variability and improve outcomes.1 These guidelines largely focus on management and treatment guidelines for 3 age groups: 8 to 21 days, 22 to 28 days, and 29 to 60 days. The inclusion criteria for these guidelines are previously healthy, term infants born at 37 weeks gestation or later, with a temperature of 100.4°F (38°C) or higher. The most significant changes to historical practice are in the 22- to 28-day and 29- to 60-day age groups. If initial laboratory work is reassuring, patients may not need cerebrospinal fluid studies, and patients may be monitored at home or at the hospital using shared decision-making with the family.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
