本研究は、英国NHSにおける非複雑な膝関節鏡検査を対象に、ナノニードル関節鏡検査（NA）と従来の関節鏡検査（CA）の温室効果ガス排出量をハイブリッド炭素足跡分析で比較した。CAは77.0 kgCO2e/件に対し、NAはMRIありで45.0、なしで35.3 kgCO2eと、それぞれ42%と54%の削減を示した。患者移動と医療機器が主要な排出源であり、NAの普及により年間208〜834トンのCO2e削減が可能と推定された。

This study compares greenhouse gas emissions of NanoNeedle arthroscopy (NA) versus conventional arthroscopy (CA) for non-complex knee procedures in the UK NHS using hybrid carbon footprint analysis. CA emitted 77.0 kgCO2e per procedure, while NA with MRI emitted 45.0 and without MRI 35.3 kgCO2e, representing reductions of 42% and 54%. Patient travel and medical devices were major contributors. Adoption modeling suggests annual savings of 208-834 tons CO2e for 5,000-20,000 procedures.

日本のGX文脈において
日本の医療分野でも脱炭素化が進む中、本研究成果は医療プロセスの効率化と排出削減の両立可能性を示す。日本ではSSBJ開示が始まり、医療機関もサステナビリティ情報の開示が求められる可能性があり、本分析手法は参考になる。
In the global GX context
Globally, healthcare contributes ~4-5% of GHG emissions. This study provides a robust methodology for assessing carbon footprints of medical procedures, relevant to ISSB-aligned disclosure and net-zero commitments in healthcare. It highlights how alternative care models can reduce emissions, offering insights for policymakers and providers.

📄 Abstract（原文）
Objective To evaluate greenhouse gas (GHG) emissions from procedure room NanoNeedle arthroscopy (NA) and its associated clinical pathway, compared with conventional arthroscopy (CA) delivered in an operating room, focusing on non-complex knee arthroscopy procedures. Design Hybrid carbon footprint analysis using process-based life-cycle methods combined with economy-wide input-output data that include environmental impact factors for medical devices and components of patient care pathways. Three care pathways were evaluated: (1) CA in an OR with preoperative MRI, (2) NA in a procedure room with MRI and (3) NA in a procedure room without MRI. Emissions were calculated for all pathway components, including patient and staff travel, diagnostic imaging, medical devices, the procedure itself and postoperative care. Setting UK National Health Service-based care pathway model for non-complex knee arthroscopy procedures. Primary and secondary outcome measures The primary outcome was GHG emissions (kgCO2e) per procedure pathway. Additional analyses assessed emissions by pathway component, adoption scenarios, conversion rates from NA to CA and sensitivity analyses for selected assumptions and input parameters. Results The CA pathway generated 77.0 kgCO₂e per procedure, whereas the NA with MRI produced 45.0 kgCO2e and NA without MRI 35.3 kgCO2e, representing reductions of 42% and 54% of kgCO2e, respectively. Major emission contributors for CA were patient travel, consumable items and general anaesthesia; for NA pathways, patient travel and the device itself were the leading contributors. Adoption modelling indicated that using NA without MRI for 5000–20 000 knee arthroscopy procedures could yield annual CO2e savings ranging from 208 tons to 834 tons. Conclusion Knee arthroscopy delivered via the NA procedure room pathway has the potential to substantially reduce environmental impact compared with conventional OR-based care. As healthcare providers and policymakers increasingly consider environmental sustainability, technologies that enable alternative care models, such as NA in a procedure room setting, may represent a promising approach for reducing the carbon footprint of selected procedures.
