Conditions of vulnerability to the inadequate treatment of bronchiolitis.

Non-recommended prescriptions were frequent. Corticosteroid and antibiotic therapy were associated with signs of severity, as expected, but interestingly, they were more frequently used in infants above 3m, which suggested less safety in the diagnosis of viral bronchiolitis in these patients. The use of bronchodilators was even more worrying since they were indiscriminately used, without association with another variable related to the severity or characteristics of the host. The use of the inhaled hypertonic solution, although not associated with severity, seems to have implied a longer hospitalization time. The identification of these conditions of greater vulnerability to the prescription of inappropriate therapies contributes to the implantation of protocols for the bronchiolitis treatment, for continuing education and for analysis of the effectiveness of the strategies employed.
