Palliative care reduces emergency room visits and total hospital days among patients with metastatic HPB and GI cancers.

Palliative care services (PCS) have improved quality of life for patients across various cancer subtypes. Minimal data exists regarding PCSfor metastatic hepatopancreaticobiliary (HPB) and gastrointestinal (GI) cancers. We assessed the impact of PCS on emergency department visits, hospital admissions, and survival among these patients. Patients with metastatic HPB and GI cancer referred to outpatient PCS between 2014 and 2018 at a single institution were included. We compared the demographics, outcomes, and end-of-life indicators between those who did and did not receive PCS. The study included 183 patients, with 118 (64.5%) having received PCS. There were no significant differences in age, gender, race, marital status, or insurance. Those receiving PCS were more likely to have colorectal cancer (p = 0.0082) and receive chemotherapy (p = 0.0098). On multivariate analysis, PCS was associated with fewer ED visits (p = 0.0319), hospital admissions (p = 0.0002), and total inpatient hospital days (p < 0.0001) per 30 days of life. Overall survival was greater among patients receiving PCS (HR: 0.65 (0.46-0.92)). Outpatient PCS for patients with metastatic HPB and GI cancer is associated with fewer emergency department visits, hospital admissions, and inpatient hospital days, and improved overall survival.
