Brief resolved unexplained event (BRUE) risk criteria
Classifies an infant BRUE as lower- or higher-risk.
Brief resolved unexplained event (BRUE) risk criteria
Age >60 days
Gestational age ≥32 weeks and postconceptional age ≥45 weeks
No CPR by a trained medical provider
Event lasted <1 minute
First event (no prior BRUE)
ResultHigher-risk BRUE
One or more lower-risk criteria not met — higher risk; further evaluation and observation are warranted.
- Lower-risk criteria met
- 0 of 5
When to use
- Classifying an infant <1 year after a brief, resolved, unexplained event to guide the extent of evaluation.
Formula
A BRUE is lower-risk only if ALL are true: age >60 days; gestational age ≥32 weeks and postconceptional age ≥45 weeks; no CPR by a trained provider; event <1 minute; and it is the first event. Any criterion not met makes it higher-risk.
Pearls and pitfalls
- A BRUE requires that no explanation is found after history and examination — an identified cause is not a BRUE.
