BackgroundEthnically Chinese adults in Canada and the United States face multiple barriers in accessing equitable, culturally respectful care at the end-of-life. Palliative care (PC) is committed to supporting patients and families in achieving goal-concordant, high-quality serious illness care. Yet, current PC delivery may be culturally misaligned. Therefore, understanding ethnically Chinese patients' use of palliative care may uncover modifiable factors to sustained inequities at the end-of-life.ObjectiveTo compare the use and delivery of PC in the last year of life between ethnically Chinese and non-Chinese adults.DesignPopulation-based cohort study.ParticipantsAll Ontario adults who died between January 1st, 2012, and October 31st, 2022, in Ontario, Canada.ExposuresChinese ethnicity.Main MeasuresElements of physician-delivered PC, including model of care (generalist; specialist; mixed), timing and location of initiation, and type of palliative care physician at initial consultation.Key ResultsThe final study cohort included 527,700 non-Chinese (50.8% female, 77.9 ± 13.0 mean age, 13.0% rural residence) and 13,587 ethnically Chinese (50.8% female, 79.2 ± 13.6 mean age, 0.6% rural residence) adults. Chinese ethnicity was associated with higher likelihoods of using specialist (adjusted odds ratio [aOR] 1.53, 95%CI 1.46-1.60) and mixed (aOR 1.32, 95%CI 1.26-1.38) over generalist models of PC, compared to non-Chinese patients. Chinese ethnicity was also associated with a higher likelihood of PC initiation in the last 30 days of life (aOR 1.07, 95%CI 1.03-1.11), in the hospital setting (aOR 1.24, 95%CI 1.18-1.30), and by specialist PC physicians (aOR 1.33, 95%CI 1.28-1.38).ConclusionsChinese ethnicity was associated with a higher likelihood of mixed and specialist models of PC delivery in the last year of life compared to adults who were non-Chinese. These observed differences may be due to later initiation of PC in hospital settings, and potential differences in unmeasured needs that suggest opportunities to initiate early, community-based PC to support ethnically Chinese patients with serious illness.© 2024.
