ContextPersons from underrepresented racial and ethnic groups experience disparities in access to and quality of palliative and end-of-life care.ObjectivesTo summarize and evaluate existing palliative and end-of-life care interventions that aim to improve outcomes for racial and ethnic underrepresented populations in the United States.MethodsWe conducted a systematic review of the literature in the English language from four databases through January 2020. Peer-reviewed studies that implemented interventions on palliative care, advance care planning, or end-of-life care were considered eligible. Data were extracted from 16 articles using pre-specified inclusion and exclusion criteria. Quality was appraised using the modified Downs and Black tool for assessing risk of bias in quantitative studies.ResultsFive studies were randomized controlled trials, and the remainder were quasi-experiments. Six studies targeted Latino/Hispanic Americans, five African Americans, and five, Asian or Pacific Islander Americans. The two randomized control trials reviewed and rated "very high" quality, found educational interventions to have significant positive effects on advance care planning and advance directive completion and engagement for underrepresented racial or ethnic groups.ConclusionThe effectiveness of advance care planning, end-of-life, and palliative care interventions in improving outcomes for underrepresented racial and ethnic populations remains uncertain. Randomized controlled trials and educational interventions indicate that interventions targeting underrepresented groups can have significant and positive effects on advance directives and/or advance care planning-related outcomes. More high-quality intervention studies that address racial and ethnic health disparities in palliative care are needed, particularly those that address systemic racism and other complex multilevel factors that influence disparities in health.Copyright © 2021 American Academy of Hospice and Palliative Medicine.
