Hospice Enrollment, Future Hospitalization, and Future Costs Among Racially and Ethnically Diverse Patients Who Received Palliative Care Consultation.

Background: Palliative care consultation to discuss goals-of-care ("PCC") may mitigate end-of-life care disparities.
Objective: To compare hospitalization and cost outcomes by race and ethnicity among PCC patients; identify predictors of hospice discharge and post-discharge hospitalization utilization and costs.
Methods: This secondary analysis of a retrospective cohort study assessed hospice discharge, do-not-resuscitate status, 30-day readmissions, days hospitalized, ICU care, any hospitalization cost, and total costs for hospitalization with PCC and hospitalization(s) post-discharge among 1,306 Black/African American, Latinx, White, and Other race PCC patients at a United States academic hospital.
Results: In adjusted analyses, hospice enrollment was less likely with Medicaid (AOR = 0.59, P = 0.02). Thirty-day readmission was less likely among age 75+ (AOR = 0.43, P = 0.02); more likely with Medicaid (AOR = 2.02, P = 0.004), 30-day prior admission (AOR = 2.42, P < 0.0001), and Black/African American race (AOR = 1.57, P = 0.02). Future days hospitalized was greater with Medicaid (Coefficient = 4.49, P = 0.001), 30-day prior admission (Coefficient = 2.08, P = 0.02), and Black/African American race (Coefficient = 2.16, P = 0.01). Any future hospitalization cost was less likely among patients ages 65-74 and 75+ (AOR = 0.54, P = 0.02; AOR = 0.53, P = 0.02); more likely with Medicaid (AOR = 1.67, P = 0.01), 30-day prior admission (AOR = 1.81, P = 0.0001), and Black/African American race (AOR = 1.40, P = 0.02). Total future hospitalization costs were lower for females (Coefficient = -3616.64, P = 0.03); greater with Medicaid (Coefficient = 7388.43, P = 0.01), 30-day prior admission (Coefficient = 3868.07, P = 0.04), and Black/African American race (Coefficient = 3856.90, P = 0.04). Do-not-resuscitate documentation (48%) differed by race.
Conclusions: Among PCC patients, Black/African American race and social determinants of health were risk factors for future hospitalization utilization and costs. Medicaid use predicted hospice discharge. Social support interventions are needed to reduce future hospitalization disparities.
