Objective To study the characteristics of patients hospitalized for asthma exacerbation during 2013-2014 in China-Japan friendship hospital.Methods This was a retrospective study involving patients hospitalized for asthma exacerbation in China-Japan friendship hospital during 2013–2014. Information about the demographic features, conditions before the admission, the treatment, the complications and the outcome were collected using the pre-designed case report form.Results The patients hospitalized for asthma exacerbation accounted for 7.5% (250/3 326) of the total patients admitted to the respiratory department. September was the peak month when the most asthmatic patients were admitted to the hospital. A total of 99 asthma patients were included for further analysis and consisted of 12 mild-onset, 22 moderate-onset, 62 severe-onset and 3 life threatening-onset. There were 49.5% (49/99) patients who had a history of previous hospitalization or emergency department visits during the last year. There were up to 54.5% (54/99) of patients who didn't use inhaled corticosteroids before the admission. Only one patient died during the hospitalization. The mortality was 1.0%.Conclusions The number of asthmatic patients admitted to the hospital fluctuates with seasons, and September is the peak month. Only a small part of patients use asthma controllers regularly before the admissions.
