We are glad to share out latest publication on Sustainability in Healthcare, in the framework of My City Labs project. The article, published by Molero et al. (2020) in the Annals of Laboratory Medicine, analyses the state of the art in research on healthcare and sustainability through exploring literature on different healthcare systems and their relations with the environment. The authors present the conceptual and practical developments regarding sustainability, as well as an overview of their evolution in the healthcare sector over time. Furthermore, they also discuss how sustainability could be applied to reduce the environmental impact of clinical laboratories by ensuring that resources are used efficiently and responsibly, and how laboratory medicine can contribute to a sustainable healthcare system through integration of innovation and emerging technologies while providing high-quality services to patients and caregivers.
