Hospice care, cancer-directed therapy, and Medicare expenditures among older patients dying with malignant brain tumors

Abstract

Background

End-of-life care for older adults with malignant brain tumors is poorly understood. The purpose of this study is to quantify end-of-life utilization of hospice care, cancer-directed therapy, and associated Medicare expenditures among older adults with malignant brain tumors.

Methods

This retrospective cohort study included deceased Medicare beneficiaries age ≥65 with primary (PMBT) or secondary (SMBT) malignant brain tumor receiving care within a Southeastern cancer community network including academic and community hospitals from 2012-2015. Utilization of hospice and cancer-directed therapy and total Medicare expenditures in the last 30 days of life were calculated using generalized linear and mixed effect models, respectively.

Results

Late (1-3 days prior to death) or no hospice care was received by 24% of PMBT (n=383) and 32% of SMBT (n=940) patients. SMBT patients received late hospice care more frequently than PMBT patients (10% vs. 5%, p=0.002). Cancer-directed therapy was administered to 18% of patients with PMBT versus 25% with SMBT (p=0.003). Non-white race, male sex, and receipt of any hospital-based care in the final 30 days of life were associated with increased risk of late or no hospice care. The average decrease in Medicare expenditures associated with hospice utilization for patients with PMBT was $-12,138 (95% CI $-18,065 to $-6210) and with SMBT was $-1,508 (95% CI $-3,613 to $598).

Conclusions

Receiving late or no hospice care was common among older patients with malignant brain tumors and was significantly associated with increased total Medicare expenditures for patients with PMBT.
