Background:
Liver cancer is the fourth cause of cancer death in the world. Hepatocellular carcinoma represents around 90% of all liver cancer, with an increase in incidence and a worsening survival rate over the years. Liver cirrhosis is the major risk factor for liver cancer development. Early involvement in palliative care/hospice care focusing on quality of life, is associated with improved physical and psychological symptoms and improvement in caregiver stress and bereavement. We examined as primary outcome the utilization and trend of palliative care (PC) among hospitalized patients with liver cancer and cirrhosis using the NIS.
Methods:
This is a retrospective study using NIS data from 2016 to 2021. We included patients aged 18 years or older who were admitted with a diagnosis of malignancy of the liver and the intrahepatic bile duct and who also had a diagnosis of fibrosis and cirrhosis of the liver. Patients who had a PC encounter during hospitalization were identified. The cohort was divided between patients with PC encounters and those without PC encounters. Cohorts were matched in a 1:1 ratio with no replacement using propensity scores. Total charges during hospitalization, length of stay (LOS), mortality, and disposition were measured as outcomes.
Results:
A total of 53,475 admissions with a diagnosis of liver malignancy and liver cirrhosis were identified. Of those, 20.8% had an encounter with a PC. The mean age of those with a PC encounter was 65.1 years (SD±7.86), while the mean age for those without was 64.5 years (SD±7.35). Sex and race were similar between both cohorts. Patients with PC encounters had a higher mean Elixhauser index (6.43 vs 5.58, p < 0.001) than those without a PC encounter. Patients with PC encounters had lower total hospital charges ($70,988 vs $94,518, p < 0.001), longer LOS (6.83 vs. 5.82 days, p < 0.001), and higher odds of mortality (aOR 7.20, CI 5.56- 9.32, p < 0.001) compared to those without a PC encounter. Patients with a PC encounter were more frequently discharged to a long-term facility (23.9% vs. 12.6%) or with home health care (36.1% vs. 18.4%) and less often had a routine hospital discharge (13.5% vs. 60.1%), compared to those without a PC encounter.
Conclusions:
This study highlights the impact of PC on patients hospitalized with liver malignancy and cirrhosis. Despite being underutilized, with only 20.8% of patients receiving PC, those who do experienced lower hospital charges, longer hospital stays, and higher in- hospital mortality. These findings suggest that PC focuses on symptom management and quality of life rather than extending life expectancy. Patients receiving PC are more frequently discharged to long-term care or home health care, indicating a shift towards supportive care. The results advocate for the broader and earlier integration of palliative care in treating liver cancer and cirrhosis to improve patient outcomes and support.
