Hur förhåller sig Region Uppsalas klimatavtryck från inhalatorer till andra regioner?

Sammanfattning: Background: Pressurized metered dose inhalers (pMDI) use propellants for pulmonary drug delivery. The propellants used in pMDI:s are strong greenhouse gases. The Powder dose inhaler (PDI) doesn’t use any propellants and contributes less to the carbon footprint. Aim: The purpose of this project is to present data on inhaler use in the Uppsala County Council in Sweden. This project aims to answer questions regarding pressurized metered dose inhalers (pMDI) carbon footprint, how prescriptions of inhaler types with lower carbon footprint compare with pMDI and how the Uppsala County Council compares with other county councils in Sweden. Methods: This cross-sectional study uses prescription data for collected inhalers in Uppsala County Council and similar county councils in Sweden. Calculations of carbon footprint of the propellants in pMDI:s and for the lifecycle of pMDI and PDI. Results: The study showed that the climate load from the greenhouse gases norflurane and apaflurane in pMDIs are 981 477kg CO2e in Uppsala County Council year 2020. Of all the county councils studied, the county council with the highest percentage of pMDIs use was Stockholm County Council, the Uppsala County Council was close second.  Conclusion: Uppsala County Council might need to review if there is a way to lower the amount of pMDI prescriptions to reduce its carbon footprint deviating from the rest of County Councils in Sweden. This project ties into Uppsala County Council goal of reducing the climate impact of medical anesthesia greenhouse gases with 10% by 2022 from 2018.
