Environmental and patient safety outcomes of a health-system Green Anesthesia Initiative (GAIA): a retrospective observational cohort study.

ABSTRACT:

Background

Inhaled anaesthetics are greenhouse gases. However, changes in the delivery of inhaled anaesthetics can mitigate environmental impact. We hypothesised that system-wide changes to the delivery of anaesthesia care would reduce environmental harm without compromising patient outcomes.

Methods

We launched the Green Anesthesia Initiative (GAIA) in March, 2022, with the aims of reducing the use of nitrous oxide, using less environmentally harmful inhaled fluorinated ethers, and increasing intravenous anaesthetic use. In this retrospective cohort study, we used electronic health record data from general anaesthetics performed on all patients older than 1 year between March 1, 2021, and Feb 28, 2023, at a single US academic medical centre across multiple sites, collecting
