  "abstract": "Background: In routine oncology practice, palliative care (PC) is commonly delivered through hospital-based consultation services integrated within existing workflows. Evidence describing real-world end-of-life (EOL) care patterns associated with consultation-based palliative care remains limited. We examined EOL care patterns associated with hospital-based palliative care consultation using linked clinical and nationwide data.\n\nPatients and methods: This retrospective cohort study used linked data from a tertiary hospital and the Korean National Health Insurance Service. We included 18,048 decedents with advanced lung, stomach, colorectal, liver, or pancreaticobiliary cancer between 2018 and 2022. To minimize selection bias, 1:2 propensity score matching was performed. Outcomes included advance care planning documentation completion, aggressive EOL interventions, hospice utilization, and medical costs.\n\nResults: After matching 4,102 patients with PC consultation and 7,910 controls, the consultation group showed significantly higher completion of advance statements (58.0% vs. 32.1%) and more patient-led decisions. During the final month of life, the consultation group had significantly fewer intensive care unit admissions (4.9% vs. 10.3%), emergency department visits (48.6% vs. 54.4%), and cardiopulmonary resuscitations (2.9% vs. 10.7%) (all P < 0.001). Hospice utilization was substantially higher in the consultation group (73.2% vs. 19.5%). Furthermore, PC consultations were associated with significantly lower medical costs during the final month and last two weeks of life.\n\nConclusion: Hospital-based palliative care consultation was associated with higher rates of advance care planning and hospice use, lower use of high-intensity EOL interventions, and modestly lower medical costs. These findings suggest that consultation-based palliative care within routine oncology workflows may meaningfully influence EOL care delivery.\n\nSupplementary Information: The online version contains supplementary material available at https://doi.org/10.1186/s12904-026-02215-9.",
