Preventable asthma-related morbidity and mortality has not improved in 20 years. The commonest reason for treatment failure is poor medication adherence, often caused by incorrect inhaler use. Up to 90% of people with asthma and a similar proportion with COPD use inhalers incorrectly. Frequent technique checks improve clinical outcomes but are costly. We propose an App to help patients identify their inhalers and to check their technique. This will require an AI model using machine learning in a training cohort to learn different inhaler types, correct technique and common errors. This could be used by any patient with a smartphone.
