目的：優質醫療與環境永續密不可分。本研究旨在建立評估醫療照護環境績效的指標架構。

方法：透過Web of Science數據庫，檢索相關主題(Topic)：「environmental sustainability in healthcare」、「impact of environmental sustainability on healthcare quality」、「healthcare quality improvement through sustainability initiatives」，從2015至2024年間發表的18篇英文研究中，整理出四大類別指標，涵蓋上游、現場、下游以及總體，以評估醫療照護對環境的影響。

結果：醫療機構對環境永續的關注多集中於現場營運的能源管理和設施設計，然而，上游供應鏈的環境影響，特別是食品、藥物和設備的採購，以及下游廢棄物處理對病人長期健康和社區的影響，仍需加強。總體指標雖反映機構的環境策略，但缺乏具體的量化指標。

結論：環境永續已成醫療品質的重要組成分，未來應發展更完善的指標體系，擴大評估範圍，涵蓋醫療價值鏈的各環節，以全面評估醫療照護的環境影響。

Objective: High-quality healthcare and environmental sustainability are intrinsically linked. This study developed a comprehensive framework for assessing healthcare services in terms of their environmental sustainability.

Methods: In a systematic literature review, we searched the Web of Science database for articles on the following topics: environmental sustainability in healthcare, impact of environmental sustainability on healthcare quality, and healthcare quality improvement through sustainability initiatives. A total of 18 studies published between 2015 and 2024 were included. The indicators of environmental sustainability in these studies were categorized into the following four types: upstream, on-site, downstream, and overall.These indicators were used to assess the environmental impact of healthcare.

Results: In terms of environmental sustainability, health-care institutions currently primarily focus on on-site energy management and facility design. However, greater attention should be given to the environmental impact of the upstream supply chain, particularly in terms of procuring food, drugs, and equipment, as well as the downstream impact of waste on patients’ long-term health and on the community. Moreover, although overall indicators reflect an institution’s environmental strategy, specific quantitative indicators remain to be established.

Conclusion: Environmental sustainability is an integral component of healthcare quality. Studies should develop more comprehensive indicator systems that expand the scope of assessment to encompass the entire healthcare value chain.This would enable a comprehensive evaluation of the environmental impact of healthcare services.
