Direct Observed Therapy of Inhaled Corticosteroids for Asthma at School or Daycare

Abstract

Background: Poor adherence with inhaled corticosteroid (ICS) medication is common in the pediatric population and can result in poor asthma control with increased frequency of asthma-related complications. The purpose of this study was to determine whether or not the initiation of ICS administration twice per day at school/daycare in patients with poor medication adherence at home improves asthma health care outcomes. Methods: We retrospectively selected patients followed by our Pediatric Pulmonology Clinic who had poorly controlled asthma and had been assigned to receive ICS twice daily at school/daycare due to poor adherence with ICS therapy. We analyzed the number of short courses of oral corticosteroids, hospital admissions, emergency department visits, and intramuscular methylprednisolone administrations for asthma exacerbations for the year before and after the intervention. The Wilcoxon signed rank test with continuity correction was used in the primary analysis. Results: Forty-nine patients who met the inclusion criteria were identified, but only 40 actually started the intervention. The number of oral corticosteroid courses per year decreased from 1.35 ± 1.1 before the intervention to 0.68 ± 1.2 (P = 0.008) postintervention, hospital admissions per year decreased from 0.45 ± 0.7 to 0.10 ± 0.3 (P = 0.006), emergency department visits per year decreased from 0.55 ± 0.8 to 0.28 ± 0.6 (P = 0.084), and intramuscular repository methylprednisolone injections per year for asthma exacerbations decreased from 0.20 ± 0.4 to 0.10 ± 0.3 (P = 0.23). Conclusion: These results indicate that school/daycare administration of ICS may be an effective option to improve indicators of asthma exacerbations in children with poor adherence to ICS at home.
