Is a temperature of 103.9 degrees Fahrenheit (hyperthermia) too high for a 2-year-old child to be treated in an urgent care (UC) setting?

From the Guidelines

A fever of 103.9°F in a 2-year-old child can be managed in an urgent care setting, as long as the child is well-appearing and does not exhibit severe symptoms, according to the clinical policy for well-appearing infants and children younger than 2 years of age presenting to the emergency department with fever 1. When evaluating a child with a high fever, it is essential to consider the risk of serious bacterial infection (SBI), which can be as high as 13% in neonates and 7% in infants aged 90 days or younger 1. However, for a 2-year-old child, the risk of SBI is lower, and the focus should be on identifying the underlying cause of the fever, which could be a viral or bacterial infection. To manage the fever, the following steps can be taken:

• Give children's acetaminophen (Tylenol) at 10-15 mg/kg every 4-6 hours or children's ibuprofen (Motrin/Advil) at 5-10 mg/kg every 6-8 hours, but never exceed recommended dosages
• Keep the child hydrated with frequent small sips of water or electrolyte solutions
• Dress them in light clothing and maintain a comfortable room temperature It is crucial to monitor the child's condition closely and seek immediate medical care if the fever persists above 102.2°F for more than 2-3 days, worsens suddenly, or is accompanied by concerning symptoms such as difficulty breathing, extreme lethargy, or a rash that doesn't blanch when pressed 1. Key considerations in the management of febrile children include:
• Determining the accuracy or validity of the temperature obtained with a home measuring device
• Assessing the child's immunization status and the capacity of the parent or caregiver to continuously monitor the child
• Identifying localizing signs of infection, such as a source of infection or focal signs of infection 1.

From the Research

Fever Management in Children

• Fever is a common symptom in children, and its management is crucial to prevent complications 2.
• The American Academy of Pediatrics recommends treating fever in children with antipyretics such as acetaminophen or ibuprofen 3, 4.

Temperature Thresholds for Urgent Care

• A temperature of 103.9 degrees Fahrenheit is considered high and may require medical attention 5.
• Children with fever without source (FWS) and a temperature of 39.0 degrees C (102.2 degrees F) or greater may be at risk of occult bacterial infections 5.
• The risk of occult pneumococcal bacteremia increases with higher temperatures, and children with FWS and a temperature of 39.5 degrees C (103.1 degrees F) or greater may require further evaluation 5.

Treatment of Fever in Children

• Combined or alternating therapy with acetaminophen and ibuprofen may be more effective than monotherapy in reducing fever in children 3, 4.
• However, the evidence for improvements in measures of child discomfort remains inconclusive, and further research is needed to determine the safety and efficacy of combined and alternating antipyretic therapy 3.
• The choice of treatment should be based on the individual child's needs and medical history, and parents should consult with a healthcare professional for guidance on managing their child's fever 2, 6.

Urgent Care Setting

• While urgent care settings can provide treatment for fever in children, a temperature of 103.9 degrees Fahrenheit may require more comprehensive evaluation and management, especially if the child has other symptoms or underlying medical conditions 5, 6.
• Parents should seek medical attention immediately if their child exhibits severe symptoms, such as difficulty breathing, seizures, or severe headache, regardless of the temperature 5, 6.
