Objective To analyze misdiagnosis of other lung diseases as asthma to avoid medical error. Methods Sixty-nine cases who were misdiagnosed as asthma between February 2012 and February 2014 were recruited. Clinical data was collected and analyzed including characteristics of symptoms, induced sputum, pulmonary function and blood tests. Results There were 13 diseases misdiagnosed as asthma, and eosinophilic bronchitis(21.74%), upper airway cough syndrome(20.29%), chronic obstructive pulmonary disease(13.04%), allergic bronchopulmonary aspergillosis(7.25%) and hyperventilation syndrome (7.25%) were the top five diseases in these cases. Some rare diseases were also found such as idiopathic hypereosinophilic syndrome and vocal cord dysfunction. Conclusions A variety of diseases have the similar clinical symptoms with asthma. The key to avoid and reduce misdiagnosis is to strengthen the understanding of asthma and similar diseases.
