Patient Perspective on Climate Impact of Inhalers

Summary

The effects of climate change on population health have considerably increased as the planet warms and is thus subjected to more heat waves, extreme weather events and food insecurity. Paradoxically, healthcare systems are major contributors to carbon emissions.

Within the field of respirology, choice of inhaler is a low-hanging fruit to address this issue. Metered dose inhalers (MDI) contain potent greenhouse gases and have been shown to have a significantly larger carbon footprint than dry powder inhalers (DPI).

The goal of the study is to assess asthma patients' willingness to change inhalers for environmental reasons as well as prescribers' willingness to prescribe a different inhaler for environmental reasons at the patient's request. The study will also be assessing patient awareness of the climate impact of inhalers and the importance that they attribute to this issue as well as other issues (cost and ease of use).

BEHAVIORAL

Educational intervention

The consented patients will be given an information packet containing an infographic about the climate impact of inhalers, a letter explaining the option of changing inhalers (which clearly outlines that the Bricanyl Turbuhaler will not cost them more money than the Ventolin) and a pre-filled prescription for Bricanyl Turbuhaler.
