With the rapid growth of healthcare waste and improvement of people’s environment awareness, the sustainability of healthcare waste management is becoming increasingly important. However, there is no research on the identification of key factors that influence sustainable healthcare waste management using the quantitative methods in the existing literature. Based on an in-depth analysis of the existing literature, we found out 15 factors influencing sustainable healthcare waste management. Then we used the interval-valued fuzzy DEMATEL (Decision Making Trial and Evaluation Laboratory) method to analyze these factors. Finally, we presented a case study to demonstrate the effectiveness of the proposed method. We found that sound legal framework supporting sustainability, strengthening sustainable management training or education programs and positive attitude and perception towards sustainable healthcare waste management are the top three most important factors. This study contributes to the literature on sustainable healthcare waste management and helps to improve the sustainability of healthcare waste management.

随着医疗废物的快速增长和人们对环境的认识的提高，医疗废物管理的可持续性变得越来越重要。然而，在现有文献中，尚无关于使用定量方法识别影响可持续医疗废物管理的关键因素的研究。在对现有文献进行深入分析的基础上，我们发现了影响可持续医疗废物管理的15个因素。然后，我们使用区间值模糊DEMATEL（决策试验与评估实验室）方法来分析这些因素。最后，我们提出了一个案例研究，以证明该方法的有效性。我们发现了支持可持续发展的健全法律框架，加强可持续管理培训或教育计划以及对可持续医疗废物管理的积极态度和看法是最重要的三大因素。这项研究为有关可持续医疗废物管理的文献做出了贡献，并有助于提高医疗废物管理的可持续性。
