Asthma Control: Improving Quality of Life and Reducing Costs

Despite evidence that asthma death rates are leveling off and asthma hospitalization rates are declining, asthma’s impact on health, quality of life, and the economy remain substantial. Rates of severe asthma continue to disproportionately affect poor and minority populations. For example, African Americans visit emergency departments, are hospitalized, and die due to asthma at rates three times higher than rates for white Americans.

The initial onset of asthma cannot yet be prevented and asthma cannot be cured. However, asthma can be controlled, and people who have asthma still can lead quality, productive lives. Asthma can be controlled by following a medical management plan and by avoiding contact with environmental "triggers." These environmental triggers include cockroaches, dust mites, furry pets, mold, tobacco smoke, and certain chemicals.
