[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.

[Analysis of short-term respiratory adverse events in 183 bronchial thermoplasty procedures].

Objective: To analyze the short-term (3 weeks) adverse respiratory events after bronchial thermoplasty(BT) in patients with severe asthma. Methods: The China-Japan Friendship Hospital recruited 62 patients with severe asthma for BT treatment from March 2014 to July 2016, with a total of 183 BT procedures. The data of adverse respiratory events within 3 weeks after procedure were collected to analyze the factors that might potentially influence the occurrence of adverse events. Results: Forty-three patients (69.4%) experienced adverse respiratory events within 3 weeks after treatment. Totally 153 adverse respiratory events occurred after 87 procedures(47.5%). The main adverse events were cough (15 events, 8.20%), sputum production (37 events, 20.22%), temporary PEF reduction (37 events, 20.22%), chest distress (12 events, 6.56%), blood in sputum (11 events, 6.01%), asthma exacerbation (10 events, 5.46%), and pneumonia(6 events, 3.28%). Most events were relieved or resolved with standard therapy in 1 week. No severe adverse events including tracheal intubation, malignant arrhythmias or death occurred within 3 weeks after procedure. The baseline eosinophil percentage in induced sputum and blood, operation times, and preoperative FEV(1) (% predicted) might influence the occurrence of adverse events after treatment. Patients with preoperative FEV(1) (% predicted) ≥60% had lower risk of adverse events. Conclusion: BT showed a good security profile in treating patients with severe asthma within 3 weeks after procedure.
