Background: Although palliative care services are increasing in the United States, disparities exist in access and utilization. Hence, we explored these factors in hospitalized patients with advanced cancers using the National Inpatient Sample (NIS). Methods: This was a retrospective analysis of NIS data, 2005 to 2014, and included patients 18 years with advanced cancers with and without palliative care consultations. Both w 2 and independent t tests were used for categorical and continuous variables. Multivariate logistic regressions were used for identifying factors associated with palliative care consultations. Results: Palliative care consultations were recorded in 9.9% of 4 732 172 weighted advanced cancer hospitalizations and increased from 3.0% to 15.
