Improving Asthma Outcomes in an Urban Pediatric Population

Prospective, randomized clinical trial of a single visit to a specialized emergency department-based asthma follow-up clinic occurring 2-15 days after emergency department care for an acute exacerbation. All patients were followed for 6 months. Analysis was by intention-to-treat with adjustment for baseline differences. Our primary hypothesis was that this intervention would decrease subsequent unscheduled visits (both to EDs and other sources of urgent care) for asthma over a six-month follow-up period. We further hypothesized that the intervention would decrease hospitalizations for asthma, improve compliance with an individualized medical plan and with trigger control, increase scheduled primary care practitioner (PCP) visits for routine asthma care, and decrease asthma symptoms while improving asthma quality of life (QOL).
