About this study

This observational study will examine the effects of thickened feeds on clinical outcomes and healthcare utilization in infants with brief resolved unexplained event (BRUE).

Read the detailed description

Brief resolved unexplained events (BRUE) are frightening episodes characterized by the appearance of life-threatening choking, pallor, cyanosis, and limpness in infants. These common events are resource-intensive and current management approaches inadequately address persistent symptoms. Infants with BRUE commonly have oropharyngeal dysphagia with aspiration, which is a modifiable risk factor for persistent symptoms, but there are no studies determining the mechanism behind this swallowing dysfunction and if swallowing interventions reduce morbidity. This is a prospective, longitudinal cohort study of infants who experienced brief resolved unexplained event receiving thickened feedings compared to those not receiving thickened feedings over 1 year.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Frequency of persistent symptoms and repeat hospitalizations over 6-month follow-up period

    Frequency of persistent symptoms and repeat hospitalizations over the 6 months after enrollment, with a comparison between those receiving and not receiving thickened feeds.

    Measured: 6 months

Secondary outcomes (1)
  1. Frequency of persistent symptoms and hospitalization risk over the full 12-month follow-up period

    Symptoms and hospitalization risk over the full 12-month follow-up period, optimal period of time needed for thickening, parent-reported anxiety levels, cost of care at Boston Children's Hospital, potential adverse effects of thickening, and urine arsenic levels, all compared between subjects receiving and not receiving thickened feeds.

    Measured: 12 months
