This study systematically investigated the extent and application of sustainability practices in the healthcare system by thoroughly examining existing research conducted on healthcare-related issues within the framework of sustainability. The review primarily focuses on three key conceptual aspects: the social, economic, and ecological dimensions of sustainability. PLS-SEM (partial least squares structural equation modeling) and MGA (multigroup analysis) for private and state healthcare organizations were applied in the study. The results show that there exists a robust positive relationship between the environmental dimension and the social dimension of health organizations’ outcomes, and the environmental dimension of the sustainability of healthcare organizations achieves a positive relationship with the economic dimension, while this relatedness is absent in the case of private healthcare organizations, for two perspectives: internal processes and learning. Moreover, the social dimension is identified as a factor that strengthens the impact of the environmental dimension on the economic dimension of health organizations’ outcomes. The results can be used in the development of policies and regulations, and for defining the strategies of healthcare organizations.
