Abstract
OBJECTIVES
This study aimed to determine if there is a difference in health care use in pediatric asthma exacerbations with dexamethasone at a standardized dose compared with a weight-based approach.
METHODS
This was a single-center, retrospective study of patients ages 2 to 17 years presenting to the pediatric emergency department (ED) with an asthma exacerbation between July 1, 2018, and June 30, 2021. Patients who received at least 1 dose of dexamethasone and had an International Classification of Diseases, 10th revision (ICD-10) code for asthma were included. The primary end point was the rate of return visits to the ED within 30 days and 31 to 90 days. Secondary end points included incidence of hospitalization and intubation, length of stay, dexamethasone dosing discrepancies, other corticosteroids or adjunctive therapies used, and medication escalation at discharge. The incidences of vomiting, hyperglycemia, and hypertension were also evaluated. Descriptive statistics were used for categoric variables and a Kaplan-Meier survival curve and Cox regression evaluated the primary outcome.
RESULTS
A total of 252 patients were included, 162 in the standardized dosing group and 90 in the weight-based group. There was no difference in return visits at 30 days and 31 to 90 days (3.1 vs 4.4, p = 0.58; and 3.7 vs 7.8, p = 0.16). The standardized group had a statistically significant shorter length of stay and lower ipratropium and magnesium use compared with the weight-based group. However, hospitalization rates were lower overall in the weight-based group. The incidences of vomiting, hyperglycemia, and hypertension were similar.
CONCLUSIONS
A standardized dosing strategy for dexamethasone in pediatric asthma exacerbations showed favorable outcomes and may lead to improved adherence.
