Abstract

Insights

Adherence to Dutch fever without an apparent source (FWS) guidelines was low in infants under 3 months. Nonadherence was common, suggesting guidelines may need revision to improve recognition and treatment of serious infections.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Clinical Guidelines

Background:

  • Dutch fever without an apparent source (FWS) guidelines aim for early recognition and treatment of serious infections in infants.
  • Assessing adherence to these guidelines is crucial for optimizing pediatric care.

Purpose of the Study:

  • To determine adherence rates to Dutch FWS guidelines in infants younger than 3 months.
  • To identify the prevalence of serious infections within this cohort.
  • To pinpoint factors associated with nonadherence to the guidelines.

Main Methods:

  • Retrospective cohort study of 231 infants with FWS across two Dutch teaching hospitals.
  • Comparison of clinical decisions against published Dutch FWS guidelines.
  • Categorization of infants into adherence and nonadherence groups based on guideline compliance.

Main Results:

  • 51.5% of infants adhered to the Dutch guidelines; 16.0% had serious infections.
  • Serious infections were more frequent in the adherence group compared to the nonadherence group.
  • Abnormal white blood cell count was linked to nonadherence (OR 0.4, P=0.049); common nonadherence reasons included omitting urine/blood cultures and IV antibiotics.

Conclusions:

  • Significant nonadherence to Dutch FWS guidelines was observed in infants under 3 months.
  • Current guidelines may require modification to enhance adherence and improve management of fever without source cases.

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Types of Fever

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.

Temperature Measurement Sites01:14

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Increased Body Temperature01:25

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...
