2018 NCI's Health Information National Trends Survey, which
asked adults ages 18 and older to describe how much they knew about palliative care. Among 3,450 respondents participating in the survey, 89 percent felt that they had an inadequate knowledge level. Participants with at least two encounters with the healthcare system over the past year and/or a regular source of healthcare were three times more likely to have adequate knowledge of palliative care compared with those with fewer encounters or no regular healthcare provider. Other factors associated with greater knowledge included being female (approximately twice the odds), being married (approximately twice the odds), and having a college degree or higher (almost 14 times greater odds).
