Objective
Poor adherence to NIH Asthma Guidelines may result in unnecessary admissions for children presenting to the emergency department (ED) with exacerbations. We determine the effect of implementing an evidence-based ED clinical pathway on corticosteroid and bronchodilator administration and imaging utilization, and the subsequent effect on hospital admissions in a US ED.
Methods
Prospective, interventional study of pediatric (≤21 years) visits to an academic ED between 2011 and 2013 with moderate-severe asthma exacerbations. A multidisciplinary team designed a one-page clinical pathway based on NIH guidelines. Nurses, respiratory therapists, and physicians attended educational sessions prior to pathway implementation. Adjusting for demographics, acuity, and ED volume, we compared timing and appropriateness of corticosteroid and bronchodilator administration, and chest radiograph (CXR) utilization with historical controls from 2006–2011. Subsequent hospital admission rates were also compared.
Results
379 post-intervention visits were compared with 870 controls. Corticosteroids were more likely to be administered during post-intervention visits (96% vs. 78%, adjusted OR 6.35; 95%CI 3.17–12.73). Post-intervention, median time to corticosteroid administration was 45 minutes faster (RR 0.74; 95%CI 0.67–0.81) and more patients received corticosteroids within 1 hour of arrival (45% vs 18%, OR 3.5; 95%CI 2.50–4.90). More patients received >1 bronchodilator dose within 1 hour (36% vs 24%, OR 1.65; 95%CI 1.23–2.21) and fewer received CXRs (27% vs 42%, OR 0.7; 95%CI 0.52–0.94). There were fewer admissions post-intervention (13% vs. 21%, OR 0.53; 95%CI 0.37–0.76).
Conclusion
A clinical pathway is associated with improved adherence to NIH guidelines and, subsequently, fewer hospital admissions for pediatric ED patients with asthma exacerbations.
