  • Disease severity and comorbidities of outpatients with asthma from urban area in China

    ObjectiveTo investigate the disease severity and comorbidities in outpatient with asthma from urban area in China.MethodsA face-to-face, questionnaire-based survey was carried out in outpatient department in 30 general hospitals from 30 provinces in China mainland except for Tibet during October 2015 to May 2016, and asthma patients who meet the including criteria were enrolled. Data of demographic characteristics, smoking status, disease severity, and comorbidities were collected.ResultsA total of 3 875 cases were included. According to GINA criteria, the proportion of diseases severity was as following: intermittent status 52.5% (2 033/3 875), mild persistent 24.5% (951/3 875), moderate persistent 16.9% (656/3 875), and severe persistent 6.1% (235/3 875). The overweight rate was 32.9% (1 274/3 875), the rate of obesity was 10.3% (401/3 875), and the smoking rate was 20.1% (777/3 875). Obesity and smoking were related to poor asthma control. 75.9% (2 941/3 875) of the patients had comorbidities: allergic rhinitis 43.4% (1682/3 875), hypertension 16.4% (634/3 875), nasosinusitis 8.7% (338/3 875), chronic obstructive pulmonary disease 7.3% (283/3 875), bronchiectasis 3.0% (118/3 875), and rhinopolypus 2.9% (114/3 875).ConclusionsThe majority of asthma patients from outpatient department are mild asthma patients. The proportion of allergic rhinitis and bronchiectasis in asthma patients is higher than mean level. Asthma patients with comorbidities of obesity and smoking is related to poor asthma control.

  • Correlation of treatment compliance analysis with lung function and control level in asthma

    ObjectiveTo analyze the relationship between medication compliance of patients with uncontrolled asthma and lung function,airway inflammation level, asthma control level and quality of life so as to obtain important references for improving patient compliance and asthma control level in the future. MethodsQuestionnaires were performed in asthma patients who did not achieve asthma control and had poor compliance in 32 third-class hospitals in 28 provinces of China mainland. All patients were tested for lung function and airway inflammation levels. So the relevant data of asthma compliance was investigated and analyzed. ResultsA total of 923 patients were investigated and the questionnaire recovery rate was 100%. Two hundred and forty-three (26.33%) answered cognitive related questions about asthma completely correctly. Treatment compliance in asthma patients was positively correlated with lung function and significantly negatively correlated with exhaled nitric oxide. Better treatment compliance in asthma has higher level of asthma control and quality of life. Poor compliance in asthma patients will lead to decreased lung function and elevated levels of airway inflammation, resulting in decreased asthma control and quality of life. ConclusionAsthma treatment compliance is related to lung function, airway inflammation, asthma control level and quality of life.
