Palliative care aims to improve quality of life and reduce suffering for seriously ill patients by providing extra support from diagnosis onward. It can be given at any point during illness alongside other treatments. A team of healthcare professionals addresses patients' physical, emotional, social, psychological and spiritual needs. Three key pillars combine these needs and manage pain and symptoms. Evidence shows broad improvements to end-of-life care are possible through better medical and social services for patients and families, which could enhance quality of life and contribute to a more sustainable healthcare system.
