Algorithm-Based Palliative Care in Patients With Cancer: A Cluster Randomized Clinical Trial

Paciente / Población Intervención / Exposición Comparación Desenlace

In 562 patients with advanced lung or non-colorectal gastrointestinal cancer identified by an EHR algorithm at 15 community oncology clinics in Tennessee, default palliative care orders in the EHR with opt-out and accountable justification, added to peer-comparison reports increased completed palliative care consultations within 12 weeks compared with peer-comparison reports with referral at clinician discretion.

ResultadoCompleted PC visit 130/296 (43.9%) vs 22/266 (8.3%) (aOR 8.9, 95% CI 5.5–14.6; P<0.001). Among 179 decedents, systemic therapy within 14 days of death 6.5% vs 16.1% (aOR 0.3, 95% CI 0.1–0.7; P=0.05). No differences in quality of life, feeling heard and understood, or late hospice referral.

Discusión y crítica

A scalable implementation strategy for guideline-recommended early palliative care in community oncology, where access lags: defaults with accountable justification lifted consultation rates from 8.3% to 43.9% and cut systemic therapy near death. The 'algorithm' is a guideline-derived EHR rule rather than a learned model, quality of life and hospice timing did not change, and the trial sits within a single oncology network. Shares its behavioural-economics lineage with Manz ML nudges (SIC).
