ANESTHESIA’S HIDDEN MOUNTAIN OF TRASH

In this episode, we explore the unexpected source of hospital waste: anesthesia practice. Dive into a newly published review that reveals how 25% of operating room waste comes from anesthesia and how addressing this can significantly reduce a hospital's environmental impact. Learn about the innovative strategies proposed to mitigate this issue, focusing on strategic placement of recycling bins and comprehensive staff education. Discover how these changes can save hospitals millions while promoting sustainability. Join us to uncover the untapped potential of greener anesthesia practices and how they can shape the future of medical waste management.

If the World practices with reusable circuits Safely, Why Don’t We?

This episode examines reusable anesthesia circuits as a practical, evidence-based strategy to reduce operating room waste, lower costs, and decrease the environmental footprint of perioperative care. We review the safety data, global adoption, and implementation considerations behind reusable breathing systems and challenge the long-standing “single-use” culture in anesthesia.

A Roadmap to Recognition: Unlocking the Joint Commission’s Green Certification

IIn this episode, we review the "who, what, and how" of the Joint Commission’s Sustainable Healthcare Certification (SHC). We explore the specific standards hospitals must meet, including the requirement to track emissions from anesthetic gases and energy use. Join us as we discuss whether this new framework is just a badge of honor or a necessary strategic tool for the future of sustainable perioperative care.

  • The official certification framework for U.S. hospitals to accelerate decarbonization. It requires hospitals to establish baseline greenhouse gas measurements (including anesthetic gases and energy) and develop an action plan to reduce emissions. The certification focuses on leadership, data collection, and performance improvement. Link: Sustainable Healthcare Certification - The Joint Commission

  • A comprehensive technical guide for hospitals undergoing the SHC review. It outlines the specific "SHC LD" (Leadership) and "SHC ME" (Measurement) standards, detailing how organizations must track data for volatile agents, nitrous oxide, and energy use to demonstrate measurable improvement. Link: Sustainable Healthcare Certification Review Process Guide - The Joint Commission

  • A resource from Practice Greenhealth, a leading industry partner, breaking down the certification's practical application. It discusses specific greenhouse gas reduction strategies required for the certification, such as anesthetic gas management, building energy efficiency, and fleet electrification.

  • Published by the International Hospital Federation in collaboration with JCI, this details the international version of the certification (HSC). It provides context for the global standard, which utilizes the "Sustainability Accelerator Tool" (SAT) for benchmarking hospital performance worldwide.

  • This session reviews the Joint Commission’s Sustainable Healthcare Certification (SHC), a framework designed to help hospitals minimize waste and reduce their carbon footprint. It highlights a case study from Seattle Children’s, which leveraged AdaptX data to cut anesthesia-related emissions by 87% and save over $175,000 annually—success that led to the creation of Project Spruce, a multi-institutional quality improvement consortium.
