End-of-life Care, Comfort Care, and Hospice: Terms and Concepts.

Purpose: This study aims to clarify and standardize the terms and concepts associated with end-of-life care, specifically within the contexts of hospice and palliative care.

Methods: We reviewed references pertaining to hospice and palliative care, including definitions of end-of-life care and comfort care. Two meetings were held with members of the medical terminology committee of the Korean Society for Hospice and Palliative Care, along with experts in the field, to establish a consensus on the terms used. In the first round, six experts participated, and in the second round, eight experts engaged in online meetings to brainstorm, exchange opinions, and review and discuss reference materials concerning terms related to hospice and palliative care.

Results: Legal definitions do not always align with those used in clinical medical settings. Although it is challenging to define the period precisely, end-of-life care encompasses all diseases, including age-related infirmities, typically spanning 6 months to 1 year. Hospice care, in contrast, includes certain non-cancerous terminal diseases as well as terminal cancer, covering a period of 3 to 6 months. Comfort care generally refers to the care provided approximately 7 days before death.

Conclusion: A conceptual understanding of terms related to end-of-life care must be reached through cultural and social consensus. Furthermore, end-of-life care should not be limited to cancer but extended to all diseases. In the future, the scope of end-of-life care should expand to encompass care for bereaved families, evolving into a more comprehensive concept of comfort care.
