Palliative care is the provision of service with an approach that is aimed at improving quality of life of patients and families through prevention and relief of suffering from physical, psychosocial, and spiritual distress. Palliative care, as used here, refers to ongoing patient management by healthcare providers who have expertise in this approach. Palliative care may be provided by interdisciplinary teams who work together to provide a holistic set of interventions to integrate the physical, psychosocial, and spiritual aspects of care.
