Association between Reusable Anesthesia Circuits and Hospital Waste Reduction, Cost Savings, and Environmental Impact: A Quality Improvement Study.
Article in Perioperative care and operating room management, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Anesthesia services are a major contributor to healthcare sector greenhouse gas emissions. Interventions aimed to reduce waste are necessary. Reusable anesthesia circuits offer a sustainable alternative to single-use circuits. Their adoption in the United States remains limited. The objective of this project was to evaluate the feasibility, cost-effectiveness, and environmental impact of using FDA-approved reusable anesthesia circuits. Methods: Supported by the SMART QI framework, we evaluated the impact of switching to reusable circuits on elective electroconvulsive therapy (ECT) procedures. We measured waste generation, room preparation times, material costs, and projected system wide financial and greenhouse gas emissions impact. Greenhouse gas emissions were estimated using the Practice Greenhealth Scope 3 Emissions Accounting Tool. Descriptive statistics compared pre- and post-intervention outcomes, with statistical significance at p < 0.05. Results: We compared 185 ECT procedures: 98 single-use from pre-intervention and 87 reusable circuits from post-intervention. Preparation times did not change. Daily waste from reusable circuits was significantly lower than single-use circuits (99.2g vs. 357.2g, p < 0.001). Cost analysis revealed 40% reduction in median per-case expenditures with reusable circuits ($4.30 vs. $8.50 per patient, p < 0.001).Scope 3 greenhouse gas emissions per procedure decreased nearly 50% (1.09 kgCO Discussion: Reusable anesthesia circuits can significantly reduce hospital waste, lower costs, and decrease carbon emissions without compromising procedural efficiency.
