Review shows substantial variations in the use of medication for infant bronchiolitis between and within countries.

AIM: Meta-analyses of randomised controlled trials on infant bronchiolitis do not support medication. We summarised the current data and evaluated the real-life use of medication for infants treated for bronchiolitis in hospitals, including paediatric wards, emergency departments and paediatric intensive care units (PICU).

METHODS

We searched PubMed for studies published from 2009 to 2018 that provided data on the real-life use of adrenaline, salbutamol, corticosteroids or antibiotics for infants hospitalised for bronchiolitis.

RESULTS

The review identified 10 such studies and showed substantial variations in medication for infant bronchiolitis between different countries and even between different hospitals in the same country. A multi-centre study including 38 hospitals in eight countries reported that a mean of 29% infants admitted for bronchiolitis received drugs without any research-based evidence on their effectiveness, ranging from 9% in Australia and New Zealand to 58% in Spain and Portugal. In addition, an American prospective multi-centre study of 16 PICUs reported that bronchodilators were used by a mean of 60%, corticosteroids by 33% and antibiotics by 63%. Other studies reported that higher ages and a history of wheezing increased the use of medication.

CONCLUSION

There were substantial variations in bronchiolitis treatment between, and within, different countries.
