Reevaluation of diagnosis in adults with physician-diagnosed asthma.

Aaron SD, Vandemheen KL, FitzGerald M, et al. JAMA. 2017;317:269-279.

Misdiagnosis can contribute to overuse of unnecessary medication and treatments as well as a delay in appropriate treatment, placing patients at increased risk of harm. This prospective cohort study suggests that asthma may be frequently misdiagnosed in the community setting as a result of inadequate testing for airflow limitations. In 2% of the cases analyzed, a serious underlying cardiorespiratory condition was misdiagnosed as asthma.
