Association Between Anesthesia Provider Education and Carbon Footprint Related to the Use of Inhaled Halogenated Anesthetics
Authors' conclusion
The setup of the sustainable anesthesia groups was associated with a dramatic reduction in the carbon footprint related to halogenated anesthetics.
Study context
- Population
- Anesthesia providers in 4 university hospitals of the Hospices Civils de Lyon, France, 2015–2020
- Participants
- 641 anesthesia providers
- Exposure
- Sustainable anesthesia groups vs Specific information campaign
- Outcome
- Estimated monthly carbon footprint from desflurane- and sevoflurane-related perioperative emissions (slope, tons.month −1)
Methodological detailsinterrupted time-series, segmented regression, multicentre
- Interrupted time-series
- Segmented regression
- Multicentre
Main finding
As reported in the abstract
Slope of carbon footprint of sevoflurane and desflurane
Before sustainable anesthesia groups
−0.27
95% CI −1.08–0.54 · tons.month −1
After sustainable anesthesia groups
−14.16
95% CI −16.67–-11.65 · tons.month −1
After information campaign
−7.58
95% CI −13.74–-1.41 · tons.month −1
After sustainable anesthesia groups vs Before sustainable anesthesia groups: P < 0.01 · After information campaign vs After sustainable anesthesia groups: P = 0.07
Observational data: associations, not effects.
