End-of-life healthcare utilization and palliative care use among older adults with limited English proficiency.

Background: Little is known about end-of-life healthcare utilization and palliative care use among older adults with serious illness and limited English proficiency (LEP).

Methods: We conducted a retrospective analysis of seriously-ill older adults (65+) with and without LEP, from a large health system, who died between 2010 and 2018. Primary outcomes were measures of healthcare utilization in the last 30 and 180 days of life: hospitalization, emergency department (ED) visits, intensive care unit (ICU) admission, and 30-day readmission. Secondary outcomes were palliative care consultation and advance care planning documents. We used multivariate analyses adjusted for sociodemographic factors including race and ethnicity.

Results: Among 18,490 decedents, 1363 had LEP. Patients with LEP were older at time of death (median age 80 vs 77 years), more likely to be female (48% vs 44%), of Asian descent (64% vs 4%), of Hispanic ethnicity (10% vs 2%), with <12th grade education (38% vs 9%), and Medicaid (36% vs 6%). In the last 30 days of life, patients with LEP had higher odds of ED visits (33% vs 20%; aOR 1.41, 95% CI 1.26-1.72; p < 0.001), readmission (12% vs 8%; aOR 1.64, 95% CI 1.30-2.07; p < 0.001), and in-hospital death (45% vs 37%; aOR 1.24, 95% CI 1.07-1.44; p = 0.005) compared to patients without LEP. Findings were similar in the last 180-days of life. Only 14% of patients with LEP and 10% of those without LEP received palliative care consultation in the last month of life. Patients with LEP were less likely to have advance care planning documents than patients without LEP (36% vs 40%; aOR 0.68, 95% CI 0.50-0.80; p < 0.001).

Conclusions: Older adults with serious illness and LEP have higher rates of end-of-life healthcare utilization. Additional research is needed to identify drivers of these differences and inform linguistically- and culturally-appropriate interventions to improve end-of-life care in this population.
