背景：正确的吸入器技术可以提高用药效果，减少剂量和副作用。患者对吸入器设备的偏好尚未得到充分的探索，我们假设如果患者有偏好并可以选择他们的吸入器，他们可能更有可能正确使用它。我们的目的是确定哮喘患者对吸入器的偏好、态度和看法，并评估这些因素是否与吸入技术有关。方法：25例哮喘患者，平均年龄43.1岁。采用定性半结构化访谈和定量患者满意度和偏好问卷（PASAPQ）来探讨患者对吸入器的偏好、态度和看法。进行客观吸入技术评价。对数据进行三角分析，以确定可能表明吸入器技术、满意度、偏好和决策之间关系的特征。结果：定性访谈的主题如下：哮喘吸入器和期望；吸入器的偏好;一种理想吸入器的特性；感知吸入器的有效性；吸入器和病人的决策。PASAPQ评分表明，无论使用何种技术，所有患者至少对吸入器“有些满意”。只有12%的吸入器被正确使用，尽管试点PASAPQ数据表明大多数患者对他们的技术有信心。吸入器技术不太可能与满意度、吸入器装置的感知或设备选择的选择有关。使用正确的吸入器技术的患者对自己的哮喘有更多的认识，并表达了实现最佳哮喘控制的动机。结论：大多数哮喘患者没有正确使用吸入器，尽管大多数患者对自己的技术有信心。患者将对吸入器技术的信心归因于他们相信吸入器是有效的。大多数患者没有参与决定使用哪种吸入装置。这些发现强调缺乏对正确吸入器技术在哮喘管理中的重要作用的理解。
Background: Correct inhaler technique can increase medication efficacy, reducing both dose and side effects. Patient preference for inhaler device has not been fully explored, and we hypothesized that if patients have a preference and can choose their inhaler, they might be more likely to use it correctly. Our aim was to determine the preferences, attitudes, and perceptions of patients with asthma toward their inhalers, and to evaluate whether any of these factors were related to inhalation technique. Methods: Twenty-five patients with asthma (mean age 43.1 years) participated. Qualitative semi-structured interviews and quantitative patient satisfaction and preference questionnaires (PASAPQ) were used to explore patients' preferences, attitudes, and perceptions about their inhalers. Objective inhalation technique assessment was performed. Data were triangulated to identify characteristics that could indicate a relationship between inhaler technique, satisfaction, preference, and decision making. Results: Themes from qualitative interviews were as follows: asthma inhalers and expectations; inhaler preference; characteristics of an ideal inhaler; perceived effectiveness of inhalers; and inhalers and patient decision making. PASAPQ scores indicated that all patients were at least “somewhat satisfied” with their inhalers, regardless of technique. Only 12% of inhalers were used correctly, despite pilot PASAPQ data suggesting that most patients were confident with their technique. The inhaler technique was unlikely to be related to satisfaction, perception of inhaler devices, or choice in device selection. Patients with correct inhaler technique were more aware of their asthma and expressed motivation to achieve optimal asthma control. Conclusions: The majority of the asthmatic patients did not use their inhaler(s) correctly, despite most having confidence in their technique. Patients attributed confidence in their inhaler technique to their belief that their inhaler was effective. Most patients had not been involved in decision making about which inhalation device to use. These findings highlight the lack of understanding of the important role of correct inhaler technique in asthma management.
