To identify factors associated with relapse following treatment for acute asthma among adults presenting to the emergency department (ED). ⋯ Among patients sent home from the ED following acute asthma therapy, 17% will have a relapse and PEFR does not predict who will develop this outcome. By contrast, several historical features were associated with increased risk. Further research should focus on ways to decrease the relapse rate among these high-risk patients. The clinician may wish to consider these historical factors when making ED decisions.
