Background: RESPIMAT® re-usable enables patients to re-use the inhaler and its availability therefore reduces the number of inhalers and associated wastage.
Objective: The objective of this study was to perform an economic evaluation that incorporates the ecological impact of adopting RESPIMAT re-usable into the healthcare system in Germany.
Methods: Inhaler costs and environmental impact over 5 years in Germany in a scenario with RESPIMAT re-usable compared to a scenario without RESPIMAT re-usable were estimated using a budget impact model. The carbon emissions were derived for each treatment pattern considering the whole life cycle (cradle-to-grave) of the inhaler product. The cost of carbon emissions was estimated using a societal cost per ton of carbon emission.
Results: By introducing RESPIMAT re-usable in Germany, it was estimated that by 2023, the number of inhalers used would have decreased by 5,748,750 compared to a scenario without RESPIMAT re-usable. In addition, this measure would reduce the environmental burden of inhaler use while at the same time reducing medical cost of inhalers.
Conclusions: Adopting RESPIMAT® re-usable to the national healthcare services may be a cost-saving option, which has the additional benefit of reducing the societal cost of carbon emissions.
