End-of-life research is a field of study that focuses on understanding and improving the experiences and care of individuals approaching death. This research area encompasses a wide range of topics, including palliative care, hospice services, advance care planning, end-of-life decision making, grief and bereavement, and cultural and ethical considerations related to death and dying. Researchers in this field work to identify and address the physical, emotional, and spiritual needs of individuals at the end of life, as well as to improve the support and resources available to their families and caregivers. Ultimately, the goal of end-of-life research is to enhance the quality of care and support provided to individuals at the end of life and their loved ones.
