Palliative care is an approach to medical care that prevents and relieves suffering associated with serious or life-threatening illness. Its central purpose is to improve quality of life for patients and their families through assessment and treatment of physical symptoms, psychological distress, social difficulties, and spiritual concerns. It is relevant to adults and children and can accompany treatment intended to cure, control, or prolong life; it is not restricted to the final days of life. (who.int)
Scope and timing
Palliative care addresses the effects of illness on the whole person rather than focusing exclusively on a particular organ or disease. It may begin at diagnosis or later, depending on the person’s circumstances and needs. Receiving it does not necessarily mean that disease-directed treatment has stopped or that death is imminent. Its services can include symptom management, coordination of care, discussion of treatment choices, and support for care partners. (nia.nih.gov)
Conditions associated with palliative needs include cancer, heart failure, chronic respiratory disease, kidney failure, neurological disorders, and dementia. The approach is also relevant to some people experiencing acute trauma, severe burns, extreme prematurity, or advanced frailty. The World Health Organization (WHO) places relief of serious health-related suffering within integrated, person-centred health services, rather than treating it solely as a service for one diagnostic group.

Symptoms and dimensions of suffering
Physical problems addressed in palliative care commonly include pain, breathlessness, fatigue, nausea, vomiting, poor appetite, and sleep disturbance. Care also encompasses mental health concerns, including anxiety, fear, and depression associated with illness and its treatment. Spiritual support can involve exploration of meaning, beliefs, and values. Practical assistance may concern employment, insurance, financial pressures, or the responsibilities borne by caregivers. The combination of services varies with individual circumstances. (cancer.gov)
Palliative treatment is not limited to comfort measures that are separate from conventional medical treatment. In cancer care, for example, chemotherapy, radiation therapy, or surgery may be used to reduce a painful tumour or relieve pressure on nerves. Such treatment has a palliative purpose when its intended benefit is relief of symptoms, although similar interventions may also be used for disease control. (cancer.gov)
Teams and care settings
Palliative care commonly involves an interdisciplinary team working with the patient, family, care partners, and clinicians treating the underlying condition. Professionals may include physicians, nurses, social workers, nutrition specialists, and chaplains. Their combined roles cover medical treatment, emotional support, practical assistance, and communication. Team composition depends on the person’s needs and the level of care required. (nia.nih.gov)
Services may be delivered in hospitals, outpatient clinics, or patients’ homes. Palliative clinicians can work alongside the existing treatment team, addressing discomfort and treatment-related side effects without replacing disease-directed care. The setting does not by itself determine whether care is palliative: the defining feature is its focus on relieving suffering and maintaining quality of life during serious illness.

Relationship to hospice and end-of-life care
Hospice care and palliative care share a focus on comfort and quality of life, but they are not interchangeable. Hospice is a particular form of care associated with the final weeks or months of life. End-of-life care, hospice services, and bereavement support can form part of the broader palliative approach, whereas palliative care can also be provided much earlier in an illness. (nia.nih.gov)
In the United States, the National Cancer Institute describes hospice as beginning when cure is no longer the goal and care centres on quality of life. Palliative care, by contrast, may accompany ongoing cancer treatment. Discussion of goals can include advance directives and communication among patients, caregivers, and clinicians about future care. These conversations are one component of care, not a substitute for symptom treatment. (cancer.gov)
Health systems and access
WHO identifies palliative care as part of universal health coverage and recognizes its relationship to the human right to health. Within a health system, provision extends beyond specialist units to primary health care, community services, and home-based care. In 2014, World Health Assembly resolution WHA67.19 called for stronger integration of palliative care throughout health services. (who.int)
Access is uneven. Documented barriers include insufficient professional training, limited funding, exclusion from national health policies, and inadequate availability of essential symptom-relieving medicines. Restrictions affecting opioid analgesics can impede pain relief. Misconceptions that palliative care applies only to cancer or only to the last weeks of life also obstruct access. These issues make service organization, workforce development, and medicine availability important public health dimensions of palliative care. (who.int)
