Trends, Sociodemographic and Hospital-Level Factors Associated with Palliative Care Utilization Among Metastatic Prostate Cancer Patients

Background: Several factors are reported to be associated with palliative care utilization among patients with various cancers, but literature is lacking on metastatic prostate cancer (MPC) specific factors. Early integration of palliative care in management of MPC patients could increase their quality of life and overall outcomes. Methods: Retrospective longitudinal analyses were conducted using the National Inpatient Sample (NIS) data (2010 - 2019). Prevalence trends in palliative care utilization were assessed, and sociodemographic and hospital-level factors associated with palliative care utilization in MPC patients were examined. Results: The overall prevalence of palliative care utilization was 13.1% with an increasing trend from 8490 to 15,231 per 100,000 MPC admissions (p-trend <.001). MPC patients aged 65 years and above had similar odds of receiving palliative care compared to younger patients. Relative to non-Hispanic Whites, other racial groups had similar likelihood to utilize palliative care services. Patients in higher median household national income quartiles had greater odds of utilizing palliative care relative to those in the first income quartile. Patients on Medicaid, private insurance and other insurance types had greater odds of palliative care use in comparison to those on Medicare. Other factors identified were hospital region, location and teaching status, patient disposition, admission type, length of stay, and number of comorbidities. Conclusion: Our findings underscore the significance of enhanced government policies and institutional support in improving palliative care use among hospitalized MPC patients. Health systems must be proactive in addressing barriers to optimization of palliative care utilization in this population.
