Steroids in Children Hospitalized With Asthma

Corticosteroids are the first-line therapy for managing acute asthma exacerbations. Studies have shown that systemic steroids effect decrease relapse and hospital admission. Due to its short half-life, Prednisone is usually given daily or twice daily for 3-5 days. It has been associated with poor compliance due it the prolonged course. Dexamethasone half-life is 36 - 72 hours. Several studies have shown no difference in outcomes between 3-5 days of prednisone and different forms of dexamethasone, including single intramuscular dose or single oral dose or two oral doses 1 day apart. However, those studies were done in the emergency department (ED). Lack of response to initial asthma treatment in ED results in admission to the hospital, implying more severe exacerbation than those able to be discharged. Some clinician shift to oral prednisone once admitted to the floor for patients who have received Dexamethasone or not. Others have begin to complete the Dexamethasone course with one more dose of Dexamethasone 24 hour after the first dose. Dexamethasone has the advantage of compliance and tolerability, however, no studies investigated its efficacy in hospitalized patients. Such knowledge will improve patient's compliance and outcomes. * Sample size calculation: Primary outcome of return to normal activities within 3 days of discharge. Based on previous studies, it is estimated that 70% of the control group will achieve this goal. Based on a minimum absolute difference of 15%, and a power of 0.80, the sample size calculated to be 117 in each arm. Assuming 20% lost to follow up, it is intended to recruit 150 in each arm (total 300 subjects). * Statistical Analysis: Demographics will be analyzed to ensure the experimental and control groups are equivalent at baseline. All proportions will be tested with Chi-square or Fisher exact test and two-sample T-test will be used for continuous variables. α = 0.05 will be used for all hypothesis tests. Interim analysis will be performed monthly and the study will be halted if any safety concerns arise. The Center for Health Equity and Quality Research (CHEQR) will help with statistical analysis * Data Safety and Monitoring Plan: The study PI and co-investigator will meet and review the collected data on a monthly basis and identify any interim results that may require a change of study protocol. Information that may affect subjects' safety will be communicated to appropriate parties in a timely fashion.
