This document provides an overview of palliative care, including: 1) Palliative care aims to relieve suffering and improve quality of life for patients facing serious illnesses, and involves addressing physical, emotional, and spiritual needs. 2) As the population ages and chronic diseases increase, more patients will benefit from palliative care services to improve end-of-life experiences and outcomes. 3) Prognostication, or predicting a patient's life expectancy, is an important but challenging skill for physicians, and palliative care aims to improve care based on patient preferences near the end of life.
