Respiratory Scores as a Tool to Reduce Bronchodilator Use in Children Hospitalized With Acute Viral Bronchiolitis.

Abstract

Adoption of clinical respiratory scoring as a quality improvement (QI) tool in bronchiolitis has been temporally associated with decreased bronchodilator usage. We sought to determine whether documented use of a clinical respiratory score at the patient level was associated with a decrease in either the physician prescription of any dose of bronchodilator or the number of doses, if prescribed, in a multisite QI collaborative. We performed a secondary analysis of data from a QI collaborative involving 22 hospitals. The project enrolled patients aged 1 month to 2 years with a primary diagnosis of acute viral bronchiolitis and excluded those with prematurity, other significant comorbid diseases, and those needing intensive care. We assessed for an association between documentation of any respiratory score use during an episode of care, as well as the method in which scores were used, and physician prescribing of any bronchodilator and number of doses. Covariates considered were phase of the collaborative, hospital length of stay, steroid use, and presence of household smokers. A total of 1876 subjects were included. There was no association between documentation of a respiratory score and the likelihood of physician prescribing of any bronchodilator. Score use was associated with fewer doses of bronchodilators if one was prescribed (P = .05), but this association disappeared with multivariable analysis (P = .73). We found no clear association between clinical respiratory score use and physician prescribing of bronchodilators in a multicenter QI collaborative.
