Abstract

Background: Poor pressurised metered-dose inhaler (pMDI) technique remains a challenge in the management of airway diseases.

Objectives: To assess pMDI technique among respiratory outpatients and identify the main indications for pMDI use and factors associated with improper use.

Methods: 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.

Results: 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.

Conclusion: Poor inhaler technique is common among respiratory outpatients. Every contact with the patient should be an opportunity to reinforce correct pMDI technique.

Keywords: inhalers; metered dose inhaler; spacers; technique.
