Evaluating inhaler technique, patient preferences and opportunities for improvement in hospitals in the UK

Abstract

Inhalers are a key aspect of managing airways disease. With effective use, they can reduce symptoms, reduce the frequency of exacerbations and thus reduce usage of healthcare services. Inhalers are associated with a significant carbon footprint, accounting for 3% of NHS' carbon emissions. We aimed to audit inhaler technique, patient preferences and inhaler prescribing and disposal to identify areas for improving the sustainability of respiratory care. An audit tool was created, and patient interviews conducted across eight different sites. Our data demonstrate that inhaler users, while self-reporting high levels of confidence in their inhaler technique, frequently make errors in inhaler technique. Additionally, the majority of patients considered the carbon footprint of their inhalers important and would consider changing to a lower carbon alternative. The majority of patients surveyed were not disposing of their inhalers correctly. This short audit has identified key areas for improvement in the quality and sustainability of respiratory care.
