<qa>  What is the 11th most common reason for asthma visits?The prevalence of asthma continues to increase. Despite the large number of available therapies, many patients continue to require emergency deparment ED visits and intensive therapy. However, ED visits continue to be a major contributor to the healthcare cost of asthma treatment. In the United States alone, asthma is the 11th most common reason for ED visits, with ED visits and hospitalizations accounting for almost 50 of the healthcare cost for asthma. Additionally, while only 20 of asthmatics have had ED visits or hospitalizations, these patients account for over 80 of the direct costs for asthma treatment. Current National Asthma Education and Prevention Program NAEPP guidelines regarding management of acute asthma exacerbations in the ED setting include: oxygenation for most patients, inhaled short-acting β2-agonists and systemic corticosteroids.
