A multi-centre, double-blind, randomised controlled study was conducted. A total of 164 patients were divided into the trial group (n = 82, treated with Bu-Fei Yi-Shen granules combined with Shu-fei Tie acupoint sticking therapy and oral sustained-release theophylline dummy) and the control group (n = 82, treated with oral sustained-release theophylline and Bu-Fei Yi-Shen granule dummy combined with Shu-fei Tie acupoint sticking therapy dummy). The COPD Self-Efficacy Scale (CSES) and the Effectiveness Satisfaction Questionnaire for COPD (ESQ-COPD) were employed during a 4-month treatment period and at the 6-month follow-up visit.
Of the 164 patients, 158 were included in the full analysis set (FAS); 145 were in the per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up, the scores of the trial group all continued to increase overtime, and the mean scores of the trial group were significantly higher than those of the control group in the following domains of the CSES: negative affect (P < 0.05), intense emotional arousal (P < 0.05), physical exertion (P < 0.05), weather/environmental (P < 0.05), and behavioural risk domain (P < 0.05). The trial group also exhibited significantly higher mean scores in the ESQ-COPD domains: capacity for life and work (P < 0.05), clinical symptoms (P < 0.05), effect of therapy (P < 0.05), convenience of therapy (P < 0.05), and whole effect domain (P < 0.05).
Bu-Fei Yi-Shen granule treatment combined with acupoint sticking therapy can improve the self-efficacy and satisfaction of COPD patients with its effectiveness.
