Palliative care is a specialized approach within healthcare research and practice focused on improving the quality of life for patients and their families facing life-limiting illnesses. As an academic concept and interdisciplinary field, it investigates the complex physical, psychosocial, and spiritual needs of individuals with serious conditions, emphasizing symptom management, communication, shared decision-making, and support systems. Its significance lies in addressing the holistic well-being of patients beyond curative treatment, aiming to relieve suffering and enhance comfort throughout the illness trajectory.
