A recent study presented during the annual meeting of the American Society of Anesthesiologists showed that hospitals are capable of significantly reducing their climate impact and surgery costs without any impact on patient safety, by making simple changes to daily anesthesia practices and reducing reliance on high-emission gases.
The healthcare sector is a major contributor to greenhouse gas emissions, and operating rooms are considered among the most resource-intensive departments. The study indicated that some inhaled anesthetic gases, particularly desflurane and nitrous oxide, represent potent greenhouse gases that trap heat in the atmosphere and increase the carbon footprint of surgical procedures.
Practical steps to reduce the carbon footprint
Etta Hanlon, the lead researcher of the study, confirmed that the results demonstrate the ability of hospitals to take feasible steps to reduce the environmental impact of surgery while maintaining quality of performance and safety. The measures taken by an academic health system comprising several sites included encouraging the use of environmentally safer anesthesia alternatives, reducing fresh gas flow rates to minimize waste, and providing physicians with periodic reports on emissions to support clinical decision-making.
Officials from medical departments participated to help establish feedback efforts for physicians. The researchers compared usage rates, emissions, costs, and patient outcomes across thousands of anesthesia cases before and after implementing the operational changes.
Financial and environmental results without compromising safety
The comparison showed a sharp decline in average total emissions per anesthesia case, exceeding the established targets for reducing emissions by a significant margin. The use of high-emission anesthetic gases decreased in favor of other alternatives, and spending on anesthetic drugs dropped noticeably.
Sustainability leaders in health institutions emphasized that patients should not have to choose between environmentally responsible healthcare and safe, high-quality care, as data proved there was no negative impact of the changes on recovery time or length of hospital stay, allowing for the benefit of sustainable care without affecting the patient experience.
