Goals-of-Care Consultations Are Associated with Lower Costs and Less Acute Care Use among Propensity-Matched Cohorts of African Americans and Whites with Serious Illness.

Background: African Americans receive more aggressive end-of-life care than Whites. Little is known about how palliative care consultation to discuss goals-of-care ("PCC") is associated with acute care utilization and costs by race. Objective: To compare future acute care costs and utilization between propensity-matched cohorts of African Americans with and without PCC, and Whites with and without PCC. Design: Secondary analysis of a retrospective cohort study. Setting/Subjects: Thirty-five thousand one hundred and fifty-four African Americans and Whites age 18+ admitted for conditions other than childbirth or rehabilitation, who were not hospitalized at the end of the study, and did not die during index hospitalization (hospitalization during which the first PCC occurred). Measurements: Accumulated mean acute care costs and utilization (30-day readmissions, future hospital days, future intensive care unit [ICU] admission, future number of ICU days) after discharge from index hospitalization.
Results: No significant difference between African Americans with or without PCC in mean future acute care costs ($11,651 vs. $15,050, p = 0.09), 30-day readmissions (p = 0.58), future hospital days (p = 0.34), future ICU admission (p = 0.25), or future ICU days (p = 0.30). There were significant differences between Whites with PCC and those without PCC in mean future acute care costs ($8,095 vs. $16,799, p < 0.001), 30-day readmissions (10.2% vs. 16.7%, p < 0.0001), and future days hospitalized (3.7 vs. 6.3 days, p < 0.0001). Conclusions: PCC decreases future acute care costs and utilization in Whites and, directionally but not significantly, in African Americans. Research is needed to explain why utilization and cost disparities persist among African Americans despite PCC.
