Data were extracted on history, disease severity, and timing of ED stabilization treatments with inhaled albuterol, ipratropium, corticosteroids, and magnesium. Primary outcome was the proportion of hospitalized children given magnesium in the ED. Secondary outcome was the ED use of \u201cintensive therapy\u201d in hospitalized children, defined as 3 albuterol inhalations with ipratropium and corticosteroids within 1 hour of triage.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>A total of 19 (12.3%) of 154 hospitalized children received magnesium (95% confidence interval 7.1, 17.5) versus 2 of 962 discharged patients. Children given magnesium were more likely to have been previously admitted to ICU (odds ratio [OR] 11.2), hospitalized within the past year (OR 3.8), received corticosteroids before arrival (OR 4.0), presented with severe exacerbation (OR 6.1), and to have been treated at 1 particular center (OR 14.9). Forty-two (53%) of 90 hospitalized children were not given \u201cintensive therapy.\u201d Children receiving \u201cintensive therapy\u201d were more likely to present with severe disease to EDs by using asthma guidelines (ORs 8.9, 3.0). Differences in the frequencies of all stabilization treatments were significant across centers.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS:<\/jats:title>\n                  <jats:p>Magnesium is used infrequently in Canadian pediatric EDs in acute asthma requiring hospitalization.
