Increasing workload in the ED is a national worry after the last 20 years. Between October and April, this phenomena is seen each year due to cold and influenza season. From an economic perspective along with a lack in human resources, new strategies have to be implemented to reduce duration and costs in office visits in the emergency department. Since mild bronchiolitis does not require a specific treatment, we hypothesize that patients liberated from triage with mild acute viral bronchiolitis would have the same rate of office re-visits than those with mild acute bronchiolitis in the emergency department.
