ObjectivesTo investigate whether asthma coaching decreases emergency department (ED) visits and hospitalizations and increases outpatient asthma monitoring visits.DesignRandomized controlled trial.SettingUrban tertiary care children's hospital.ParticipantsPrimary caregivers (hereafter referred to as parents) of children aged 2 to 10 years with asthma who have Medicaid insurance coverage and are urban residents who were attending the ED for acute asthma care.InterventionEighteen months of participating in usual care (control group) vs receiving coaching focused on asthma home management, completion of periodic outpatient asthma monitoring visits, and development of a collaborative relationship with a primary care provider (intervention group).Main Outcome MeasuresThe primary outcome was ED visits. Secondary outcomes were hospitalizations and asthma monitoring visits (nonacute visits focused on asthma care). Outcomes were measured during the year before and 2 years after enrollment.ResultsWe included 120 intervention parents and 121 control parents. More children of coached parents had at least 1 asthma monitoring visit after enrollment (relative risk [RR], 1.21; 95% confidence interval [CI], 1.04-1.41), but proportions with at least 4 asthma monitoring visits during 2 years were low (20.0% in the intervention group vs 9.9% in the control group). Similar proportions of children in both study groups had at least 1 ED visit (59.2% in the intervention group vs 62.8% in the control group; RR, 0.94; 95% CI, 0.77-1.15) and at least 1 hospitalization (24.2% in the intervention group vs 26.4% in the control group; 0.91; 0.59-1.41) after enrollment. An ED visit after enrollment was more likely if an ED visit had occurred before enrollment (RR, 1.46; 95% CI, 1.16-1.86; adjusted for study group), but risk was similar in both study groups when adjusted for previous ED visits (1.02; 0.82-1.27).ConclusionThis parental asthma coaching intervention increased outpatient asthma monitoring visits (although infrequent) but did not decrease ED visits.Trial Registrationclinicaltrials.gov Identifier: NCT00149500.
