Quality for All: Clinical Trial Enrollment and End-of-Life Care in Solid and Hematologic Malignancies

Background

Patients with incurable cancer deserve quality end-of-life (EOL) care. Despite established EOL quality metrics, many patients receive aggressive EOL care with limited goals of care (GOC) documentation. Concurrently, clinical trials are critical for advancing cancer care. We aim to identify associations between trial enrollment in the last year of life (YOL) and EOL quality metrics for adults with cancer to identify opportunities to advance goal-concordant care.

Methods

This is a retrospective review of adult patients with cancer at a single academic institution who died between January 2018 and October 2022. Outcomes included: initiation of a new anticancer therapy, intensive care unit (ICU) admission, hospitalization, or emergency department (ED) encounter in the last 30 days of life (DOL), reception of anti-cancer treatment in the last 14 DOL, referral to hospice, referral to palliative care, and GOC documentation.

Results

Among 9817 patients, 577 (5.9%) enrolled in clinical trials in the last YOL. Patients enrolled in trials were more likely to initiate new anticancer treatments in the last 30 DOL (p = < 0.001), less likely to have a palliative care referral (p = < 0.001) or GOC documentation (p = < 0.001), but were less likely to have an ED encounter in the last 30 DOL (p = 0.04) or die in an acute care setting (p = 0.015).

Conclusions

Enrollment in clinical trials in the last YOL was associated with metrics of aggressive EOL care, with low rates of GOC documentation to determine if this care is goal-concordant. Low rates of palliative care and hospice engagement across the study population suggest opportunities for improvement for all patients, regardless of trial enrollment.
