Objectives: To explore the experiences of people involved in UK palliative care day services (PCDS) and identify the important outcomes of this service. Methods: Focus groups were carried out separately with patients, informal carers and volunteers from four purposively selected palliative care day units and with day unit managers from 11 units. Results: Patients benefited from both the support of PCDS professionals and social support of fellow PCDS patients, which contributed to a perceived improvement in their quality of life.
