论文摘要
医疗保健中普遍存在的不可持续的带有可持续的线性经济为全球温室气体排放贡献了4.4％。一种流行的但尚未广泛的解决方案是再制造常见的一次性医疗设备，例如电生理导管，通过启用圆形生命周期来大大延长其寿命。为了支持采用导管再制造，我们提出了一个全面的排放框架，并通过生命周期分析（LCA）对处女制造和再制造的碳排放进行了整体评估。我们遵循ISO建模标准和NHS报告指南，以确保行业相关性。我们得出的结论是，再制造可能导致每回合最多减少60％（-1.92 kg CO2EQ，无负担）和每人57％（-1.87 kg CO2EQ，负担）。我们广泛的敏感性分析和行业知识的回购计划模拟显示，每次再制造导管寿命（-1.73 kg CO2EQ）的长期排放减少高达48％。我们的全面结果鼓励采用电生理导管再制造，并强调了除传统排放指标外，估计长期排放的重要性。
The unsustainable take-make-dispose linear economy prevalent in healthcare contributes 4.4% to global Greenhouse Gas emissions. A popular but not yet widely-embraced solution is to remanufacture common single-use medical devices like electrophysiology catheters, significantly extending their lifetimes by enabling a circular life cycle. To support the adoption of catheter remanufacturing, we propose a comprehensive emission framework and carry out a holistic evaluation of virgin manufactured and remanufactured carbon emissions with Life Cycle Analysis (LCA). We followed ISO modelling standards and NHS reporting guidelines to ensure industry relevance. We conclude that remanufacturing may lead to a reduction of up to 60% per turn (-1.92 kg CO2eq, burden-free) and 57% per life (-1.87 kg CO2eq, burdened). Our extensive sensitivity analysis and industry-informed buy-back scheme simulation revealed long-term emission reductions of up to 48% per remanufactured catheter life (-1.73 kg CO2eq). Our comprehensive results encourage the adoption of electrophysiology catheter remanufacturing, and highlight the importance of estimating long-term emissions in addition to traditional emission metrics.
