Abstract
Objective: To determine if adherence to an asthma treatment pathway is associated with a decrease in hospitalizations.
Methods: A prospective cohort design was conducted of Thai children aged 2–15 years who visited the emergency department with severe asthma exacerbations, defined as a Buddhasothorn Asthma Severity Score ≥ 8. Patients who received systemic corticosteroids and nebulized short-acting beta-2 agonists combined with ipratropium bromides were classified as the adherence group. The timing of steroid and bronchodilator administration, length of hospital stay, and hospitalization rate were examined in relation to adherence to the asthma pathway. Multivariable logistic regression models and adjusted odds ratios were used to assess associations.
Results: A total of 118 episodes of asthma exacerbations (EAEs) from 59 participants were included. Patients who adhered to the pathway had a significantly higher rate of systemic corticosteroid administration within 1 h of arrival at triage (88.6% vs. 41.9%, adjusted Odds Ratio: aOR 10.21; 95%CI 3.52–29.62). A higher proportion of the patients who adhered to the pathway also received inhaled ipratropium bromide ≥ 2 doses within 1 h of arrival at triage (72.7% vs. 12.2%, aOR 23.51; 95%CI 7.73–71.54) and it was administered significantly faster by 31 min (5 min vs. 36 min, p < 0.001) compared to non-adherence group. The hospitalization rate was significantly lower by almost half of EAEs for adherence group (36.4% vs. 63.5%, aOR 0.41; 95%CI 0.18–0.93).
Conclusions: Accurate assessment of severity and adherence to the clinical pathway can reduce hospitalization in pediatric patients with severe asthma exacerbations.
