The role of actuaries within the health sector varies considerably from one country to another, due to differences in the local evolution of health systems and the funding models for health services. There has historically been little involvement of actuaries in the UK's health sector but the skillset of actuaries is highly relevant to many of the challenges being faced within the NHS today, such as with moves towards embedding population health management approaches and the development of Integrated Care Systems in England. Additionally there is growing interest in new and expanding roles that IFoA members could play in the health sector around the world. The webinar will present an overview of the latest work of two IFoA Working Parties that cover the UK and global perspectives. It will include the outputs and preliminary findings from a member survey and from interviews with key stakeholders. It will then describe case studies in which actuaries have pioneered their skills to address challenges in the UK and in Singapore.
