Poor pressurised metered-dose inhaler (pMDI) technique remains a challenge in the management of airway diseases.
To assess pMDI technique among respiratory outpatients and identify the main indications for pMDI use and factors associated with improper use.
This was a prospective, quantitative descriptive study conducted at the adult respiratory clinic of Universitas Academic Hospital in Bloemfontein, South Africa. A convenience sample of 100 participants was used. Each participant was interviewed and required to demonstrate the use of a placebo pMDI, either alone or with a large-volume spacer. Inhaler technique was evaluated according to the UK Inhaler Group standard for inhaler therapy.
Chronic obstructive pulmonary disease and asthma were the most common indications for pMDI use. Of the 100 participants, 97 preferred a pMDI without a spacer (pMDI alone) and three preferred using the inhaler with a spacer. In the pMDI-alone group, 13 participants (13.4%) demonstrated correct technique and 65 (67%) made more than one error.
Poor inhaler technique is common among respiratory outpatients. Every contact with the patient should be an opportunity to reinforce correct pMDI technique.
压力定量吸入器（pMDI）使用技术欠佳仍是气道疾病管理中的一项挑战。
评估呼吸科门诊患者的pMDI使用技术，并确定pMDI使用的主要适应证以及与使用不当相关的因素。
这是一项在南非布隆方丹大学学术医院成人呼吸科门诊进行的前瞻性定量描述性研究。采用了100名参与者的便利样本。对每位参与者进行访谈，并要求其演示使用安慰剂pMDI，可单独使用或与大容量储雾罐一起使用。根据英国吸入器治疗组的吸入器技术标准对吸入器使用技术进行评估。
慢性阻塞性肺疾病和哮喘是pMDI使用最常见的适应证。100名参与者中，97人更喜欢使用不带储雾罐的pMDI（仅使用pMDI），3人更喜欢使用带储雾罐的吸入器。在仅使用pMDI的组中，有13名参与者（13.4%）演示了正确的技术，65名（67%）出现了不止一处错误。
吸入器使用技术欠佳在呼吸科门诊患者中很常见。每次与患者接触都应成为强化正确pMDI使用技术的机会。
