Optimal Asthma Control = Fewer Trips to the ED


How can repeated visits to the emergency department (ED) for asthma exacerbations best be avoided?

Q: How can repeated visits to the emergency department (ED) for asthma exacerbations best be avoided?

A: The goals of management of chronic persistent asthma are to eliminate symptoms and to achieve maximum functioning. We now have the knowledge and the pharmacologic agents to help attain these goals.1

Most patients who have asthma exacerbations use short- and long-acting bronchodilators for control of symptoms. But these "rescue" medications do not address the fundamental pathology of asthma, which involves inflammation of the airways. Because it drives bronchospasm, inflammation must be suppressed. Inhaled corticosteroids are the mainstay therapy for managing airway inflammation. These agents, such as fluticasone (which does not increase the risk of osteopenia2), have an excellent safety profile.

Nevertheless, a recent study showed that at follow-up visits, primary care physicians infrequently added inhaled corticosteroids to the regimen of asthmatic patients discharged from the ED after an exacerbation.3 Even if these agents were prescribed, their impact was not evident during subsequent visits. This is probably because the prescription was not filled or was not used as intended.

Asthma guidelines stress the long-term use of inhaled corticosteroids because this strategy reduces morbidity.4 A new study suggests a possible alternative for titration of corticosteroid doses in patients with mild to moderate disease (Box). Approximately two thirds or more of patients who have chronic persistent asthma with exacerbations can achieve complete control with step therapy that involves inhaled corticosteroids, leukotriene modifiers, and long-term b2-agonists.5,6

It is a challenge for many clinicians to succeed in having patients adhere to an effective maintenance management program.7 Yet we have the ability to control symptoms--and thus to improve quality of life--in most patients with asthma.
