International skilled heath worker migration is a key feature of the global economy, a major contributor to socio-economic development and reflective of the transnationalization of health and elder care that is underway in most OECD nations. The distribution of care and health workforce planning has previously been analysed solely within national contexts, but increasingly scholars have shown how care deficits are being addressed through transnational responses. This Element examines the complex processes that feed health worker migrants into global circulation, the losses and gains associated with such mobility and examples of good practices, where migrants, sending and destination communities experience the best possible outcomes. It will approach this issue through the lens of problems, and solutions, making connections across the micro, meso and macro within and across the sections.
