Medical assistance in dying (MAiD) is a globally polarising topic which often sparks debate surrounding the ethical and moral dilemmas that arise with a life-ending intervention. To gain a better understanding of this intervention, it is important to explore the experience of those most intimately affected by MAiD. Family caregivers of those with a terminal illness are the backbone of the healthcare and support team, often providing a substantial amount of informal care while at the same time coping with their own distress and anticipatory grief. However, we know the least about how MAiD impacts the psychosocial well-being of these same individuals. The aim of this article is to explore the experience of MAiD from the family caregiver perspective, namely their beliefs and opinions about the intervention, how the process of MAiD impacts them, how the intervention shapes their view of their loved one’s quality of death, and the psychosocial outcomes after the passing of their loved one. Beyond the literature, challenges within both the clinical and research realms will be discussed and future directions will be offered. While MAiD is currently legal in only a small number of countries, a better understanding of the impact of MAiD will help inform policy and legislation as they are developed in other jurisdictions. Further, this article aims to inform future research and clinical interventions in order to better understand and support those seeking MAiD and their families.
