Asthma control and future asthma-related morbidity in inner-city asthmatic children

Background Asthma guidelines recommend routine evaluation of asthma control, which includes measurements of impairment and risk. It is unclear whether rigorous asthma control changes risk of asthma morbidity. Objective To examine whether the degree of asthma control in inner-city asthmatic children results in differential risk reduction of future asthma-related morbidity. Methods This retrospective observational study examines 960 inner-city children with asthma who were highly engaged in an asthma-specific disease management program for a minimum of 2 years. Degree of asthma control was determined during the first year of enrollment and was categorized as well controlled (≥80% of visits in control), moderately controlled (50%-79% of visits in control), or difficult to control (
