The healthcare system emits greenhouse gas emissions and produces waste that in turn threatens the health of populations. The objective of our study was to measure the ecological threat related to intravitreal injections.
Emissions were separated into scope 2 corresponding to Heating, Ventilation and Air Conditioning (HVAC) of the building, and scope 3 corresponding to travels (patients and staff), and life cycle assessment (LCA) of medical devices (MD) and pharmaceutics. Greenhouse gas (GHG) emissions and waste for a single injection were first measured through a waste audit, and secondly anticipated theoretically with a calculator.
The average GHG emissions and waste measured were 277kgCO2eq/IVI and 0.5kg/IVI, respectively. Pharmaceuticals were responsible for 97% of total emissions. Emissions unrelated to pharmaceuticals counted for 8.4kgCO2eq/IVI. GHG emissions and waste estimated with the calculator were 276kgCO2eq/IVI and 0.5kg/IVI, respectively, showing that the calculator was accurate.
Our study provides a puzzle piece to carbon footprint and waste assessment in the field of ophthalmology. It may help provide concrete data for future green vs. vision discussions.
医疗体系会排放温室气体并产生废物，而这些反过来又会威胁到人群的健康。我们的研究目的是衡量与玻璃体内注射相关的生态威胁。
排放被分为 2 个范围，分别对应建筑物的供暖、通风和空调（HVAC）以及 3 个范围，对应患者和员工的旅行以及医疗器械和药物的生命周期评估（LCA）。首先通过废物审计测量单次注射的温室气体（GHG）排放和废物，其次使用计算器进行理论预测。
平均 GHG 排放量和废物测量值分别为 277kgCO2eq/IVI 和 0.5kg/IVI。药品占总排放量的 97%。与药品无关的排放占 8.4kgCO2eq/IVI。计算器预测的 GHG 排放量和废物分别为 276kgCO2eq/IVI 和 0.5kg/IVI，表明计算器是准确的。
我们的研究为眼科领域的碳足迹和废物评估提供了一个拼图。它可能有助于为未来的绿色与视觉讨论提供具体数据。
