Acute bronchiolitis is common in young children, and some children develop chronic cough after their bronchiolitis. We thus undertook systematic reviews based on key questions (KQs) using the PICO (Population, Intervention, Comparison, Outcome) format. The KQs were: Among children with chronic cough (> 4 weeks) after acute viral bronchiolitis, how effective are the following interventions in improving the resolution of cough?: (1) Antibiotics. If so what type and for how long? (2) Asthma medications (inhaled steroids, beta2 agonist, montelukast); and (3) Inhaled osmotic agents like hypertonic saline? ⋯ The panel made several consensus-based suggestions and identified directions for future studies to advance the field of managing chronic cough post-acute bronchiolitis in children.
