The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines for chronic obstructive pulmonary disease (COPD) recommend considering patient preference when choosing an inhaler device. However, few studies have assessed both inhaler satisfaction and factors associated with high inhaler satisfaction. Therefore, we assessed inhaler satisfaction and determinants of high satisfaction in Korean COPD patients.
COPD patients were prospectively enrolled from January 2018 to November 2019. The 308 inhalers used by the 261 participants in this study included dry powder inhalers (Turbuhaler, Breezhaler, Ellipta, Diskus, and Genuair), a soft mist inhaler (Respimat), and pressurized metered dose inhalers (pMDIs). Inhaler satisfaction was assessed by the Feeling of Satisfaction with Inhaler (FSI-10) questionnaire. High inhaler satisfaction was defined as an FSI-10 ≥ 43.
Among 261 COPD patients, 163 (62.5%) were highly satisfied with their inhaler device. The rates of high inhaler satisfaction for Turbuhaler, Breezhaler, Ellipta, Diskus, Genuair, Respimat, and pMDI usage were 40.0%, 67.2%, 66.7%, 50.0%, 55.6%, 63.4%, and 45.0%, respectively ( = 0.215). In univariate analyses, higher body mass index, non-current smoker, GOLD grades I and II, a modified Medical Research Council (mMRC) score < 2, lower inhaler puff burden, once daily usage of inhaler, and good inhaler adherence were associated with high inhaler satisfaction. In multivariate analyses, an mMRC score < 2, and good inhaler adherence were independently associated with high inhaler satisfaction.
High inhaler satisfaction was associated with dyspnea symptom and good inhaler adherence in COPD patients. Effective strategies are needed including appropriate inhaler device selection, consideration of patient preference, and repeated inhaler education to improve patient satisfaction of inhalers.
全球慢性阻塞性肺疾病倡议（GOLD）慢性阻塞性肺疾病（COPD）指南建议在选择吸入器设备时考虑患者的偏好。然而，很少有研究评估吸入器的满意度和与高满意度相关的因素。因此，我们评估了韩国 COPD 患者的吸入器满意度和高满意度的决定因素。
从 2018 年 1 月至 2019 年 11 月，前瞻性招募了 COPD 患者。在这项研究中，261 名参与者共使用了 308 个吸入器，包括干粉吸入器（都保、碟式、思力华、准纳器、奥克斯）、软雾吸入器（瑞普特）和压力定量吸入器（pMDI）。使用吸入器满意度量表（FSI-10）评估吸入器满意度。高吸入器满意度定义为 FSI-10≥43。
在 261 名 COPD 患者中，有 163 名（62.5%）对其吸入器设备非常满意。都保、碟式、思力华、准纳器、奥克斯、瑞普特和 pMDI 的高吸入器满意度率分别为 40.0%、67.2%、66.7%、50.0%、55.6%、63.4%和 45.0%（=0.215）。单因素分析显示，较高的体重指数、非吸烟、GOLD 分级 I 和 II、改良的医学研究委员会（mMRC）评分<2、较低的吸入器喷雾量、每日使用一次吸入器和良好的吸入器依从性与高吸入器满意度相关。多因素分析显示，mMRC 评分<2 和良好的吸入器依从性与高吸入器满意度独立相关。
COPD 患者的高吸入器满意度与呼吸困难症状和良好的吸入器依从性有关。需要采取有效的策略，包括选择合适的吸入器设备、考虑患者的偏好以及反复进行吸入器教育，以提高患者对吸入器的满意度。
