Insights
Most infants hospitalized for brief resolved unexplained events (BRUE) do not receive a diagnosis during their hospital stay. Further research is needed to identify which infants benefit most from hospitalization for BRUE evaluation.
Area of Science:
- Pediatrics
- Emergency Medicine
- Neonatology
Background:
- Hospitalization is common for young infants presenting with brief resolved unexplained events (BRUE) to the emergency department (ED).
- The diagnostic yield of hospitalization for BRUE in infants without an initial explanatory diagnosis is not well-established.
Purpose of the Study:
- To determine the rate of explanatory diagnoses identified during hospitalization for infants with BRUE.
- To investigate factors associated with identifying an explanatory diagnosis during hospitalization.
Main Methods:
- Multicenter retrospective cohort study of infants hospitalized with BRUE.
- Inclusion criteria: infants without an explanatory diagnosis at admission.
- Data collected on diagnostic testing, consultations, and observed events during hospitalization.
Main Results:
- 37.0% of 980 infants received an explanatory diagnosis during hospitalization.
- Diagnostic testing, consultations, or observed events contributed to diagnosis in only 17.9% of cases.
- Serious diagnoses were identified in 1.5% of infants, most commonly seizures.
Conclusions:
- The majority of hospitalizations for BRUE do not yield an explanatory diagnosis.
- Most identified diagnoses are benign or self-limited.
- Further research is required to optimize hospitalization criteria for BRUE evaluation.
Background And Objectives:
Most young infants presenting to the emergency department (ED) with a brief resolved unexplained event (BRUE) are hospitalized. We sought to determine the rate of explanatory diagnosis after hospitalization for a BRUE.
Methods:
This was a multicenter retrospective cohort study of infants hospitalized with a BRUE after an ED visit between October 1, 2015, and September 30, 2018. We included infants without an explanatory diagnosis at admission. We determined the proportion of patients with an explanatory diagnosis at the time of hospital discharge and whether diagnostic testing, consultation, or observed events occurring during hospitalization were associated with identification of an explanatory diagnosis.
Results:
Among 980 infants hospitalized after an ED visit for a BRUE without an explanatory diagnosis at admission, 363 (37.0%) had an explanatory diagnosis identified during hospitalization. In 805 (82.1%) infants, diagnostic testing, specialty consultations, and observed events did not contribute to an explanatory diagnosis, and, in 175 (17.9%) infants, they contributed to the explanatory diagnosis (7.0%, 10.0%, and 7.0%, respectively). A total of 15 infants had a serious diagnosis (4.1% of explanatory diagnoses; 1.5% of all infants hospitalized with a BRUE), the most common being seizure and infantile spasms, occurring in 4 patients.
Conclusions:
Most infants hospitalized with a BRUE did not receive an explanation during the hospitalization, and a majority of diagnoses were benign or self-limited conditions. More research is needed to identify which infants with a BRUE are most likely to benefit from hospitalization for determining the etiology of the event.
