Klimabewusste Verordnung von Inhalativa – Umsetzung in der hausärztlichen Praxis

The healthcare sector is responsible for 5.2% of CO₂ emissions in Germany. The prescribing of medicines is a significant contributor. Among the prescribed medicines, metered dose inhalers (MDIs) play a decisive role due to the propellant gases they contain. A relevant reduction in emissions is possible by switching to dry powder inhalation systems (DPI).

The guideline “Climate-conscious prescribing of inhalants” is intended to provide assistance in the prescribing of inhaled medicines by summarising the available evidence on the decision between DPI and MDI and explicitly addressing the aspect of climate damage caused by propellants. It addresses everyone involved in prescribing and counselling those affected.

The S2k guideline was drawn up under the joint leadership of DEGAM (German College of General Practitioners and Family Physicians) and the German Society for Pneumology and Respiratory Medicine (DGP) under moderation of the AWMF (Association of the Scientific Medical Societies in Germany). The main contents from a practical perspective are presented in this paper.

Overall, MDIs account for a high proportion of inhaler prescriptions in Germany. The aspects of climate damage should be considered when prescribing MDIs. In order to facilitate implementation in practice, several decision aids were developed.

The guideline is the first to address the importance of prescribing a group of medicines in relation to climate change. The degree of implementation of the guideline recommendations can be determined by future analyses of prescription data. A planned practical test is required to check the acceptance of the decision aids.
