The Social Stratification of Older Adults’ Preparations for End-of-Life Health Care

Life-sustaining medical care of patients with advanced cancer at the end of life (EOL) is costly. Patient-physician discussions about EOL wishes are associated with lower rates of intensive interventions. Funded by the National Institute of Mental Health and the National Cancer Institute, Coping With Cancer is a longitudinal multi-institutional study of 627 patients with advanced cancer. Patients were interviewed at baseline and were followed up through death. Costs for intensive care unit and hospital stays, hospice care, and life-sustaining procedures (eg, mechanical ventilator use and resuscitation) received in the last week of life were aggregated. Generalized linear models were applied to test for cost differences in EOL care. Propensity score matching was used to reduce selection biases. Of 603 participants, 188 (31.2%) reported EOL discussions at baseline. After propensity score matching, the remaining 415 patients did not differ in sociodemographic characteristics, recruitment sites, illness acknowledgment, or treatment preferences. Further analyses, adjusted by quintiles of propensity scores and significant confounders, revealed that the mean (SE) aggregate costs of care (in 2008 US dollars) were $1876 ($177) for patients who reported EOL discussions compared with $2917 ($285) for patients who did not, a cost difference of $1041 (35.7% lower among patients who reported EOL discussions) (P =.002). Patients with higher costs had worse quality of death in their final week (Pearson production moment correlation partial r = -0.17, P =.006). Patients with advanced cancer who reported having EOL conversations with physicians had significantly lower health care costs in their final week of life. Higher costs were associated with worse quality of death.

We reviewed the research literature on racial or ethnic diversity and end-of-life decision making in order to identify key findings and provide recommendations for future research. We identified 33 empirical studies in which race or ethnicity was investigated as either a variable predicting treatment preferences or choices, where racial or ethnic groups were compared in their end-of-life decisions, or where the end-of-life decision making of a single minority group was studied in depth. We conducted a narrative review and identified four topical domains of study: advance directives; life support; disclosure and communication of diagnosis, prognosis, and preferences; and designation of primary decision makers. Non-White racial or ethnic groups generally lacked knowledge of advance directives and were less likely than Whites to support advance directives. African Americans were consistently found to prefer the use of life support; Asians and Hispanics were more likely to prefer family-centered decision making than other racial or ethnic groups. Variations within groups existed and were related to cultural values, demographic characteristics, level of acculturation, and knowledge of end-of-life treatment options. Common methodological limitations of these studies were lack of theoretical framework, use of cross-sectional designs, convenience samples, and self-developed measurement scales. Although the studies are limited by methodological concerns, identified differences in end-of-life decision-making preference and practice suggest that clinical care and policy should recognize the variety of values and preferences found among diverse racial or ethnic groups. Future research priorities are described to better inform clinicians and policy makers about ways to allow for more culturally sensitive approaches to end-of-life care.
