Objective: To assess the impact of guidelines of the consensus conference in September 2000 on the ambulatory management of acute bronchiolitis in infants.
Methods: Prospective multicenter study, in four hospitals in the North department in France, during three epidemic periods: the winter preceding the consensus conference and the two following winters. All the infants between 30 days and 2 years of age, admitted to an emergency care unit for a first or second episode of bronchiolitis were included. The infants' characteristics and ambulatory treatments prescribed were collected.
Results: Six hundred thirty-eight infants were included: 169 before the conference and 469 after. Seventy-seven percent had consulted previously and a prescription had been drawn-up for 77%. There was no difference in the frequency of drug prescriptions or physiotherapy between the three periods. After the conferences, inhaled beta(2) agonists were still prescribed in 21% of cases, inhaled corticosteroids in 15%, oral corticosteroids in 34%, antibiotics in 53% and mucolytics in 54%. Physiotherapy was prescribed for 58% of the infants.
Conclusion: Two years after the consensus conference, the ambulatory treatment of bronchiolitis has no changed, corticosteroids, beta(2) agonists, antibiotics and mucolytics are still prescribed in excess. Further studies, within a few years, are required to reassess the application of the guidelines, not only in outpatient but also in inpatient management.
