A new "risk index" could help physicians predict which adult patients with asthma will have attacks during the next year.
In a study presented last month at the American Lung Association/American Thoracic Society International Conference in Chicago, Ill, researchers from The Johns Hopkins University School of Medicine and School of Public Health offered several predictors of poor outcomes. The most accurate predictors, they reported, are visiting the emergency department in the past 2 years and canceling activities in the past month.
