Achieving and maintaining asthma control in inner-city children

BackgroundDespite guidelines-defined care, inner-city children of low socioeconomic status have poor asthma control.ObjectiveThis study evaluated time to achieve control, maintenance of control, and factors associated with well controlled asthma for pediatric patients receiving specialty-based asthma care in mobile asthma clinics designed to reduce barriers to delivering effective asthma care (the Breathmobile Program).MethodsExisting clinical data collected from January 1998 to June 2008 for 7822 pediatric patients with asthma (34,339 visits) enrolled in similarly structured mobile asthma programs across the United States evaluated the effect of asthma control on the reduction of asthma-related morbidity, time to achieve asthma control, maintenance of asthma control, and factors associated with well controlled asthma.ResultsComparison of pre and post year data for subjects enrolled in the program for at least 1 year revealed reductions in the percentage of patients reporting emergency department visits (mean, 66%), hospitalizations (mean, 84%), and missed school days ≥5/year (mean, 78%). Well controlled asthma was achieved by visit 3 for an estimated 80% of patients. Factors contributing to well controlled asthma include non-African American race, visit interval <90 days, and adherence to prescribed therapy.ConclusionThis study demonstrates the ability to achieve and maintain asthma control in high-risk populations in association with intensive, accessible, guidelines-defined care with close follow-up.
