Trends and disparities in place of death among patients with cholangiocarcinoma: A two-decade analysis.

Objectives: Cholangiocarcinoma (CCA) is the second most lethal primary hepatic malignancy. It has been well-reported that most cancer patients prefer to die at home or in a hospice facility. However, there is limited data on the place of death for CCA patients. We evaluated trends and disparities in place of death for patients with CCA from 1999 to 2020.

Methods: Using the CDC WONDER database (1999-2020), we calculated the frequency of CCA deaths at home/hospice and the average annual percentage change (AAPC) over this period stratified by race, age, gender, and region. We employed logistic regression to assess for associations between these variables and place of death for patients whose death was attributed to CCA.

Results: Among 140,422 deaths, a rise in deaths occurred in home/hospice facilities compared to inpatient medical or nursing facilities across all variables examined. Blacks and individuals ≥ 85 had the highest proportion of deaths outside of home/hospice. However, Blacks showed the highest AAPC (8.56%) in home/hospice deaths, followed by Asians (AAPC 8.44%). In contrast, individuals aged 45-54 saw the lowest AAPC (4.27%). Non-whites were less likely to die at home/hospice, with Blacks demonstrating the lowest adjusted odds ratio (aOR 0.64). Those ≥ 85 were less likely to die in home/hospice (aOR 0.78), whereas individuals aged between 55-64 (aOR 1.11) and 65-74 (aOR 1.12) had increased odds of dying in these settings. Patients from the Western region were the most likely to die at home/hospice (aOR 1.04).

Significance Of Results: Our study highlights disparities in place of death of patients with CCA amongst races, regions, and ages. Non-whites, extremes of ages, and patients from the Northeast have disproportionately poor outcomes in terms of end-of-life care in the US. These findings emphasize the need for efforts to address sociodemographic disparities in end-of-life care to improve patient-centered health outcomes.
