Objectives: Limited evidence investigates how knowledge, misconceptions, and beliefs about palliative care vary across patients with cancerous versus non-cancerous chronic disease. We examined the knowledge of and misconceptions about palliative care among these groups.
Methods: We used weighted data from the National Cancer Institute Health Information National Trends Survey 5 (Cycle 2) for nationally representative estimates and logistic regression to adjust for respondent characteristics. We identified respondents who reported having (1) cancer ([n = 585]; breast, lung, and colorectal), (2) chronic conditions ([n = 543]; heart failure, lung disease, or chronic obstructive pulmonary disorder), or (3) neither cancer nor other chronic conditions (n = 2,376).
Results: Compared to cancer respondents, chronic condition respondents were more likely to report being Black or Hispanic, report a disability, and have lower socioeconomic status. In the sample, 65.6% of cancer respondents and 72.8% chronic conditions respondents reported they had never heard of palliative care. Chronic condition respondents were significantly (p < 0.05) less likely to report high palliative care knowledge than cancer respondents (9.1% vs. 16.6%, respectively). In adjusted analyses, cancer respondents had greater odds of high palliative care knowledge (odd ratio [OR] = 1.70; 95% confidence interval [CI] = 1.01, 2.86) compared to respondents with neither cancer nor chronic disease; chronic condition respondents did not have increased odds (OR = 0.96; CI = 0.59, 1.54).
Significance of results: Disparities in palliative care knowledge exist among people with non-cancerous chronic disease compared to cancer. Supportive educational efforts to boost knowledge about palliative care remains urgent and is critical for promoting equity, particularly for underserved people with chronic illnesses.
