Community Care for Croup (RCT)

Study Overview
=================
Brief Summary
-----------------
This randomized clinical trial was to compare the effectiveness of prednisone 2mg/kg/day for 3 days vs. dexamethasone 0.6mg/kg for 1 day for treatment of children with mild or moderate croup. It was conducted in a practice-based research network of community pediatricians in the St. Louis area. Outcomes included additional health care for croup, duration of symptoms, nights of disturbed sleep, parental stress, missed work days, and adverse events. Our hypothesis was that community-based treatment of children with mild or moderate croup with multiple doses of prednisone is superior to a single dose of dexamethasone.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Additional Health Care | The primary outcome was the % of participants who had additional health care for croup within 11 days of randomization assessed by self-report. This dichotomous variable was positive if any of the following occurred: office visit, ED visit or hospitalization for croup care. | 11 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Duration of Croup Symptoms |  | 12 days | 
| Nights With Disturbed Sleep |  | 12 days | 
| Parental Stress | Parental stress due to the child's illness was rated using a 4-point categorical scale (ranging from 3-very stressed to 0-not stressed). We report days until the stress rating was 0. | 12 days | 
| Time Missed From Work |  | 12 days | 
| Number of Participants With Reported Side Effects |  | 12 days |
