Abstract

Background: good inhaler technique and medication concordance is important for symptom and disease control in chronic airways disease. Objectives: establish the prevalence of inhaler use; the main inhaler devices used by older people at home; their ability to use the inhalers they have been prescribed; and the relationship between perceived ease of use and actual performance. Design: cross-sectional population based study. Subjects: subjects aged 70 years and over living at home. Methods: 500 subjects were randomly selected from 5,002 subjects aged 70 years and over living at home. Inhalers used over the previous 24 hours were identified by a nurse on home visit. Those with cognitive impairment were excluded. Inhaler system was assessed and graded by a doctor as acceptable (perfect or minor errors) or unacceptable (major errors), using previously published criteria. Perceived ease of use of the device was rated as easy, moderate or difficult. Results: 423 subjects participated in the study. The population prevalence of inhaler use was 15.8% (12.0, 19.7). Of the 91 inhaler devices used, 39 (42.8%) were metered dose inhalers, 34 (37.4%) were metered dose inhalers with large volume spacers, and 18 (19.8%) were breath-actuated devices. Thirty-two subjects (82.1%) using metered dose inhalers had an acceptable technique compared with 33 (97.1%) of those using metered dose inhalers with large volume spacers and 13 (72.2%) of those using breath-actuated devices (P < 0.05). Up to three quarters of inhalers were considered easy to use but 12% of subjects who rated their inhaler device as being easy to use made major errors. Conclusion: metered dose inhaler was the most frequently prescribed inhaler and was used correctly by most subjects especially in combination with large volume spacers. Major errors were more common with breath-actuated devices. Inhaler technique should be checked as patients’ perception of their inhaler skills correlates poorly with actual performance.
