この研究は、タイにおける虫垂炎治療における低価値医療の削減が、炭素排出量と医療費の節約にどの程度寄与するかを推定した。パンデミック前後のデータを用いて、CTスキャンの増加が炭素排出を悪化させる一方、症例数減少により全体の炭素排出は減少した。社会的炭素コストを用いた経済的節約は約45万8千バーツと試算された。低価値医療の削減は環境と経済の両面で有益であると結論付けている。

This study estimates carbon and economic savings from reducing low-value appendicitis treatments in Thailand. Using data from pre-pandemic, lockdown, and post-lockdown periods, it finds that carbon emissions decreased by 13.9% by 2021 despite a 71.8% increase in CT scans. Total healthcare costs fell by 4.5%, and economic savings from the social cost of carbon were about $13,000. The study supports reducing low-value care for environmental and economic co-benefits.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも医療分野の脱炭素化は進んでいるが、本論文はタイの事例であり日本の政策に直接つながらない。ただし、低価値医療削減が炭素削減に貢献するという考え方は、日本での医療機関の環境負荷低減策の参考になる可能性がある。
In the global GX context
This study provides empirical evidence from Thailand linking healthcare quality improvement (reducing low-value care) with carbon emissions reduction. While context-specific, it contributes to the global discussion on sustainable healthcare, which is increasingly relevant under ISSB's social and environmental reporting.

📄 Abstract（原文）
Background: Health sector is responsible for around 5–10% of the global greenhouse gas (GHG) emissions. World Health Organization (WHO) estimates 20–40% of current medical care is low value. Reducing such care can result in health, economic, and environmental co-benefits. The objective of this study is to estimate carbon and economic savings from reducing low-value appendicitis treatment in Thailand. Methods: Data on potentially low-value appendicitis treatments in Thailand were extracted from our previous study across three periods: pre-pandemic (March–June 2019), lockdown (March–June 2020), and post-lockdown (March–June 2021). Carbon emissions related to appendicitis treatment were extracted from published literature: computed tomography (CT) scans [9.2 kg carbon dioxide equivalent (CO 2 e)], ultrasound (0.5 kg CO 2 e), open surgery (22.7 kg CO 2 e), and laparoscopic surgery (27.4 kg CO 2 e). Economic impact was estimated using the social cost of carbon at $0.185 per kg CO 2 e. Results: Appendicitis cases dropped by 13.4% and 16.4% during lockdown and post-lockdown, respectively. As a result, carbon emissions decreased by 11.6% during lockdown and 13.9% by 2021. However, CT scan use increased by 71.8% by 2021, creating 18.4 times more emissions than ultrasound. While treatment costs per case increased by 14.2% in 2021, total healthcare costs fell by 4.5% due to reduced appendicitis cases. Economic savings from averted social cost of carbon were estimated to be 458,921 Thai baht (THB) (~$13,000) from 2019 to 2021. Conclusions: Reducing low-value appendicitis care can save money and reduce carbon emissions. Effective use of the updated World Society of Emergency Surgery (WSES) Jerusalem guidelines can help optimize diagnosis and treatment of appendicitis.
