Abstract
The literature reports that Asthma Inhaler technique has not improved during the last forty years, despite improvement strategies focused on educating users to improve their technique and compliance. This is particularly critical for reliever inhaler users when ‘use error’ may result in a full asthma attack and possible death. This paper presents a pilot study Human Factors design review of the standard UK reliever inhaler, commonly referred to as ‘the blue puffer’. The results indicate a mismatch between ‘work as done’ and ‘work as imagined’ and that this mismatch appears to be influenced by the design of the inhaler. Conceptually it appears possible to improve the design of technical components of the inhaler system to reduce use errors and hence improve patient safety. This would require appropriate scenario and user testing, with any changes being integrated into the system as a whole.
