The nursing workforce is facing significant change; it is ageing and the demand for part-time working is increasing. More of its traditional entrants are choosing alternative careers. Facing these recruitment and retention issues while simultaneously trying to improve productivity and the quality of care is challenging. Traditionally popular solutions that involve recruiting nurses from the international marketplace can clearly help but they bring their own human resources management challenges (Buchan and Seccombe, 2011). In this Policy+, we focus on nurse migration into the UK from other EU countries. The evidence was collected as part of the PROMeTHEUS study (tinyurl.com/EOHSP-prometheus). It is one of the first using a survey and interviews to explore the HR management challenges and the factors influencing decision making at different stages, specifically of the EU migration process of health professionals.
