    Brief Resolved Unexplained Events (BRUE) Criteria for Infants

    Classifies unexplained events and replaces the Apparent Life Threatening Events (ALTE) classification.

    INSTRUCTIONS

    Use in infants <1 year old who are asymptomatic and in their normal state of health at the time of evaluation. Do not use in symptomatic patients (e.g. fever, respiratory distress) or those with obvious cause for prior symptoms.

    When to Use
    Pearls/Pitfalls
    Why Use

    Infants <1 year old presenting for evaluation after a brief, unexplained, and now resolved event consisting of ≥1 of the following:

    • Cyanosis or pallor.
    • Absent, decreased, or irregular breathing.
    • Marked change in tone.
    • Altered level of responsiveness.
    • Developed via expert consensus by the American Academy of Pediatrics (AAP).
    • The criteria require that an extensive history and physical examination have failed to reveal a cause of the episode.
    • Can be used in inpatient, outpatient, and emergency department settings.
    • Note that choking, gagging, and red color change, which were part of the ALTE definition, are not part of the BRUE Criteria.
    • Risk is defined by the likelihood of adverse recurrent events or eventual diagnosis of a serious underlying disorder.
    • BRUEs represent a separate entity from sudden infant death syndrome (SIDS).
    • Replaces the term ALTE, which is broader and does not identify patients who are lower risk.
    • May give providers comfort in discharging lower risk BRUE patients home.
    • May reduce the need for unnecessary diagnostic testing which may be invasive and expensive.
    Entry criteria
