Abstract
Background
Systemic corticosteroids are vital to critical asthma management. While intravenous methylprednisolone is routinely used in the pediatric intensive care unit (PICU) setting, recent data supports dexamethasone as an alternative. Using the Pediatric Health Information System (PHIS) registry, we assessed trends and variation in corticosteroid prescribing among children hospitalized for critical asthma.
Methods
We performed a multicenter retrospective cohort study using PHIS data among children 3-17 years of age admitted for critical asthma from 2011 through 2019. Primary outcomes were corticosteroid prescribing rates by year and participating sites. Exploratory outcomes were corticosteroid-related adverse effects, rates of adjunctive pharmaceutical and respiratory interventions, mortality and length of stay.
Results
Of the 49 children's hospitals assessed, 26 907 encounters were included for study. Mean dexamethasone exposure rates were 18.1 ± 2.4% where 2.4 ± 1.2% represented dexamethasone-alone prescribing. Dexamethasone alone prescribing exhibited a linear trend (annual increase of 0.5 ± 0.1% annually R2 = 0.845) without correlation to cumulative site critical asthma admission rates. Compared to encounters prescribed solely methylprednisolone or a combination of dexamethasone and methylprednisolone, subjects provided dexamethasone alone had reduced asthma severity indices, length of stay, and exposure rates to adjunctive asthma interventions. Adverse events were rare and the dexamethasone-alone group less frequently experienced gastritis and hyperglycemia.
Conclusions
In this multicenter retrospective study from 49 children's hospitals, dexamethasone prescribing rates appear increasing for pediatric critical asthma. Observed variability in corticosteroid prescribing implies a continued need for controlled prospective comparative analyses to define ideal corticosteroid regimens for pediatric critical asthma.
