Knowledge and beliefs about end-of-life care and the effects of specialized palliative care: a population-based survey in Japan.

To clarify the knowledge and beliefs of the Japanese general population related to legal options, pain medications, communication with physicians, and hydration/nutrition in end-of-life care, and to explore the associations between end-of-life care they had experienced and these beliefs, a questionnaire survey was conducted on two target populations: 5000 general population subjects and 866 bereaved family members of cancer patents who died in 12 palliative care units in Japan. The respondents were requested to report the legal knowledge about end-of-life options, pain-related beliefs, communication-related beliefs, and hydration/nutrition-related beliefs, and their experiences with end-of-life care. A total of 3061 responses were analyzed (effective response rate, 54%).
