Earlier ENT review in recurrent croup went with shorter illness and fewer emergency visits

Design

Retrospective single-centre cohort (level III)

Population

70 children evaluated by ENT for recurrent croup, 2011–2024

Primary outcome

Disease duration, emergency visits, steroid prescriptions, age at resolution

Effect

Shorter time to ENT review correlated with shorter disease (r 0.51), fewer ED visits and steroid courses (r 0.28 each)

This retrospective cohort reviewed 70 children seen by paediatric otolaryngology at a US tertiary hospital for recurrent croup between 2011 and 2024, examining comorbidities, social circumstances (measured by the Childhood Opportunity Index) and the timing of referral.

Household tobacco smoke exposure and gastro-oesophageal reflux were associated with earlier onset of croup. Children from areas with better wealth, health and educational resources had shorter disease, fewer emergency visits and resolved younger. A shorter interval from first emergency visit to ENT evaluation correlated with fewer emergency visits (r 0.28), fewer steroid courses (r 0.28) and shorter disease duration (r 0.51).

Recurrent croup — typically defined as two or more episodes a year, or croup outside the usual age range — can signal subglottic stenosis, a haemangioma or reflux-related airway disease. The practical message for paediatricians and GPs is to ask about smoke exposure and to refer rather than keep re-treating. The correlations are modest and cannot show that early referral itself shortened the illness.

• Refer a child with recurrent croup (two or more episodes a year, or onset outside age 6 months to 3 years) for ENT airway assessment.
• Ask about household smoking, including bidis and chulha smoke, and advise on removing exposure.
• Look for reflux disease and manage it according to paediatric GERD guidance.
• Suspect a structural cause — subglottic stenosis or haemangioma — when croup occurs in infancy or without a viral prodrome.
• Record each emergency visit and steroid course; the count supports the case for referral.

Why it matters

Recurrent croup is often managed episode by episode, while the underlying airway problem goes unexamined.

Don't overread it

Seventy children at one centre with modest correlations; it does not show early referral causes faster resolution.

The statistics, in plain English

A correlation coefficient (r) of 0.28 is weak and 0.51 moderate. These describe how closely two measures move together, not how much one changes the other, and sicker children may simply have been referred differently.
