Translating Evidence Into Practice: Implementing Caregiver Burden Assessments in Palliative Care Clinic.

BackgroundCaregiver burden assessments lack clinical uniformity in palliative care. Existing evidence-based interventions often impose resource demands that are prohibitive for smaller programs.Objectives(1) Demonstrate the practical utility of routine caregiver screening paired with an interdisciplinary team (IDT) response protocol. (2) Identify patient and caregiver factors influencing burden.DesignSetting: Cross-sectional study in a US outpatient palliative care clinic.Measurements: The 12-item Zarit Burden Interview (ZBI-12) was administered by a nurse or social worker. Scores guided immediate, point-of-care IDT interventions.ResultsOf 81 approached caregivers, 74 completed the ZBI-12 (72% female; median age 56). Burden was stratified into mild (n = 37), mild-moderate (n = 22), and high (n = 15) tiers, with median scores increasing significantly (6 vs 16 vs 28; P < 0.001). General counseling was consistent across tiers (∼54%). However, high-intensity supportive interventions rose significantly with burden severity: social work telephone follow-ups increased (0% vs 13.6% vs 33.3%; P < 0.001), support group referrals rose (2.7% vs 31.8% vs 46.7%; P < 0.001), and psychotherapy referrals increased (0% vs 4.5% vs 13.3%; P = 0.030). Multivariable linear regression showed lower patient Palliative Performance Scale (PPS) scores independently predicted higher caregiver burden. Each 10-point decrease in PPS correlated with a 2.4-point increase in total ZBI-12 score (β = -0.240; 95% CI, -0.433 to -0.048; P = 0.015).ConclusionThis workflow provides a replicable roadmap to transition caregivers from "invisible patients" to actively supported extensions of the care unit, reinforcing dyadic assessments as standard practice in outpatient palliative medicine.
