The overarching objective of this Staff Exchanges (SE) program is to form an international network of organizations from Spain, Germany, Slovenia, and China, working on a joint research program in the fields of health, development economics, and anthropology. Population medicine is a new medical paradigm that aims to improve the aggregate and long-term population health by mobilizing available resources through various care responsibilities. The principles of population medicine are aimed at forcing doctors and physicians to shift from a reactive model that treats ill individuals to a proactive model that focuses on the population's health. This SE Program focuses on how economics, as a collection of theories, models, techniques, and values, might enable practitioners in providing better and more efficient treatment to the population they serve. The People’s Republic of China has become a global leader in large-scale preventive screening and the digitalization of healthcare, making essential strides towards a population medicine paradigm. 23 researchers will conduct 144 PMs of secondments in Training, Data Collection, and Research Work in the four countries to Develop an economic framework for population medicine, estimate the causal impact of renewable energy and digital telecommunications infrastructure on sustainable development outcomes, and conduct a social and cultural analysis of the effects of health and sustainable development policies on European immigrants in China. The results will enable European and international medical training institutions to develop better programs and solutions to target and improve the aggregate health of their respective societies. It will bring together these existing collaborating partnerships into an interdisciplinary consortium that synergizes the intersections of their complementary research lines of health, sustainable development, and cultural integration through the training and staff exchange programs.
