Pathway analysis of medication belief, compliance and asthma control level in elderly patients with asthma / 中国实用护理杂志

ABSTRACT

Objective:To investigate the current situation of medication belief, compliance and asthma control level of elderly patients with asthma, and to analyze the influencing factors of asthma control level, so as to provide theoretical reference for improving asthma control level of elderly patients with asthma.Methods:Using the convenient sampling method, 325 elderly patients with asthma were selected from the respiratory clinic of Jilin Central Hospital and the Affiliated Hospital of Beihua University from June to December 2019. The general information, medication belief, compliance and the level of asthma control in elderly patients with asthma were evaluated by general information questionnaire, the specific medication beliefs scale (BMQ-S), Chinese bronchus Asthma medication adherence scale (MARS-A) and Asthma Control Test scale (ACT).Results:The scores of BMQ-S, MARS-A and ACT were (2.82±8.36), (3.67±0.85) and (17.96±5.10) respectively. Regression results showed that age, education level, medication belief and compliance were important influencing factors of asthma control level in elderly patients with asthma ( P<0.05 or 0.01), which could explain 77.9% of variation. The total score of asthma control level was positively correlated with the total score of belief in taking medicine and the total score of compliance ( r values were 0.704, 0.775, P<0.05). The structural equation model fit index between the necessity of medication belief, the concern of medication belief, the compliance and the level of asthma control was high, the path coefficient significantly ( P<0.05), compliance had a mediating effect between the necessity of medication belief and the level of asthma control. The direct and indirect effects of the necessity of medication belief on the level of asthma control in elderly asthmatics were 0.320 and 0.389 respectively, and the direct effect of medication belief concern on the level of asthma control was-0.089. Conclusions:The medication belief necessity and medication belief concern have a direct predictive effect on asthma control level in elderly patients with asthma, and compliance has a mediating effect between medication belief necessity and asthma control level.
