Introduction: Palliative care (PC) utilization remains low among pancreatic cancer patients. This study explores the association of PC with mental health service and pharmacotherapy utilization among pancreatic cancer patients. Methods: Retrospective analysis was conducted on a sample of patients in the United States with newly diagnosed pancreatic cancer using Electronic Health Record data from Optum’s Integrated Claims-Clinical data set. Subsequent diagnoses of anxiety and depression and PC consultation encounters were determined using ICD-9/10 codes. Adjusted associations of mental health treatments with PC and patient characteristics were quantified using multiple logistic regression. Results: Among newly diagnosed pancreatic cancer patients (n = 4029), those with PC consultations exhibited a higher prevalence of anxiety (33.9% vs. 22.8%) and depression (36.2% vs. 23.2%). Mental health service use and pharmacotherapy varied, with the highest utilization among patients having both anxiety and depression. Treatment pattern was also influenced by age (aOR 1.832 for age <55 vs. 65–70 years). Notably, PC consultations showed no significant effect on the likelihood of documented treatment. Discussion: Our study emphasizes underutilization of PC and MH treatment for pancreatic cancer patients. These findings imply a crucial need for further investigation into palliative care’s role in addressing mental health concerns among pancreatic cancer patients.

Introduction: Women with late-stage metastatic breast cancer are at an increased risk of pain and distress from symptoms and often struggle with associated emotional and financial burden of their disease. Palliative care is known to alleviate symptom burden in patients with end-stage, terminal diseases but is often underutilized in both inpatient and outpatient settings. The current study aims to investigate the prevalence of palliative care consultation on inpatients with metastatic breast cancer and examine the association between palliative care consultation and length of hospital stay and total hospital charges. Methods: Patients diagnosed with metastatic breast cancer between 1998–2017 were abstracted from the Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Database (NIS). The primary outcome was the presence of a palliative care consultation (PCC) during the inpatient stay. Secondary outcomes were hospital length of stay and total hospital charges. Multivariable logistic regression was used to examine factors associated with the presence of a PCC. The relationship between PCC and hospital length of stay and total hospital charges were investigated using linear regression. Results: 513,509 cases of metastatic breast cancer were identified, 5.7% had a documented in-hospital palliative care encounter. Of those who received PCC, total hospital charges were about USD 5452 less than those who did not receive consultation. Women who received PCC had higher odds of a longer hospital stay. Predictors of PCC were older age, non-White race, and residing in a lower-income ZIP code. Conclusions: Palliative care remains to be an underutilized resource among patients with end-stage metastatic breast cancer.
