The practice of healthcare management is essential for the efficient operation of health services, encompassing leadership, management, and direction within healthcare organisations. ‘Health management’ extends beyond healthcare management by integrating principles of public health and health policy. As health management is commonly practised but not cohesively recognised, the European Health Management Association (EHMA) conducted this study to develop a cohesive definition of health management. Developed through a qualitative methodology comprising focus group discussions and validation through quantitative expert interviews, this study proposed a holistic definition of health management, incorporating social, environmental and economic determinants of health, cross-sector collaboration, and the ‘One Health’ approach. The publication of this unified definition has important implications for professional training, policy development, and health outcomes. It provides a standardised framework for curricula, informs precise policy formulation, and promotes sustainable, efficient, and equitable healthcare delivery.
