[Effect of long-term asthma management on asthma patients from China-Japan Friendship Hospital]

Objective: To investigate the outcome of long-term asthma management of China-Japan Friendship Hospital. Methods: A face-to-face, questionnaire-based survey was carried out in outpatient department in 30 general hospital (including China-Japan Friendship Hospital) from Oct 2015 to May 2016. Data of demographic characteristics, asthma control, asthma management, asthma attacks and self-management, disease perception was collected. Results from China-Japan Friendship Hospital were compared to the national mean level within the same period. Results: Altogether 150 asthmatic outpatients were recruited from China-Japan Friendship Hospital. Asthma control level was significantly higher than the national asthma control level[56.7% (85/150) vs 28.5% (1 099/3 854), P<0.001]. The rate of hospitalizations due to asthma exacerbations was significantly lower than the national hospitalization rate[13.3% (20/150) vs 26.4% (1 017/3 858), P<0.001]. The rate of peak flow meter (PFM) usage was significantly higher than the national PFM usage rate[50.7% (76/150) vs 10.1% (388/3 837), P<0.001]. For reasons of not using PFM, the proportion of doctors never introduced was lower than the national level[43.3% (65/150) vs 65.2% (2 518/3 860), P<0.001]. As to the choice of anti-asthmatics when symptoms deteriorated, the proportion of inhaled corticosteroid (ICS)+ formoterol was significantly higher than the national level[70.0% (105/150) vs 45.8% (1 776/3 875), P<0.001]. The proportion of the patients that had right perception on disease nature was significantly higher than the national level[78.7% (118/150) vs 69.0% (2 660/3 857), P=0.011]. The proportion of the patients that had right perception on medication choice on daily-used first-line medication for chronic asthma was significantly higher than the national level[70.7% (106/150) vs 60.2% (2 321/3 857), P=0.010]. Conclusion: The level of asthma control, disease management and disease perception in China-Japan Friendship Hospital are much higher than national level due to the conduction of long-term asthma management.
