CONTEXT: Early palliative care referral has demonstrated benefits in quality of life and end-of-life outcomes, yet results have been inconsistent across cancer types. Previous guidelines recommended time-based referrals, but optimal timing may vary by individual patient factors.
OBJECTIVES: Investigate factors associated with the timing of referral to palliative care and the impact of timing of referral and the number of appointments on end-of-life outcomes.
METHODS: We conducted a retrospective analysis of 779 patients with metastatic solid tumors referred to outpatient palliative care at two cancer center sites (2021-2023). We examined referral patterns and analyzed associations between timing, patient characteristics, and end-of-life outcomes. For bivariate analysis, "early" was defined as referral within three months of diagnosis.
RESULTS: Overall, 38.9% of patients received early referrals, with significant variation by cancer type (P < 0.001): patients with head and neck cancer had the highest early referral rate (53.3%) while those with breast cancer had the lowest (9.6%). Patients with Medicaid insurance were more likely to receive early referral (42.8% vs. 35.2%, P = 0.04). Among 321 patients who died during follow-up, earlier referral relative to death was associated with increased hospice enrollment (OR 1.016 per month, P = 0.01), reduced end-of-life chemotherapy (OR 0.964 per month, P = 0.002), lower hospital death rates (OR 0.988 per month, P = 0.04), and decreased ICU utilization (IRR 0.962, P = 0.02). The timing of referral proved more influential than visit intensity across all end-of-life outcomes.
CONCLUSION: Palliative care referral timing varies significantly by cancer type and insurance status. Earlier referral relative to death influenced end-of-life outcomes more than visit intensity, supporting stepped models, which have found noninferior outcomes to early palliative care despite fewer visits.
