BackgroundFew trials have examined long-term outcomes of advance care planning (ACP) interventions. We examined the efficacy of an ACP intervention on preparation for end-of-life decision making for dialysis patients and surrogates and for surrogates' bereavement outcomes.Study DesignA randomized trial compared an ACP intervention (Sharing Patient's Illness Representations to Increase Trust [SPIRIT]) to usual care alone, with blinded outcome assessments.Setting & Participants420 participants (210 dyads of prevalent dialysis patients and their surrogates) from 20 dialysis centers.InterventionEvery dyad received usual care. Those randomly assigned to SPIRIT had an in-depth ACP discussion at the center and a follow-up session at home 2 weeks later.Outcomes & MeasurementsPrimary Outcomespreparation for end-of-life decision making, assessed for 12 months, included dyad congruence on goals of care at end of life, patient decisional conflict, surrogate decision-making confidence, and a composite of congruence and surrogate decision-making confidence.Secondary Outcomesbereavement outcomes, assessed for 6 months, included anxiety, depression, and posttraumatic distress symptoms completed by surrogates after patient death.ResultsPrimary Outcomesadjusting for time and baseline values, dyad congruence (OR, 1.89; 95% CI, 1.1-3.3), surrogate decision-making confidence (β=0.13; 95% CI, 0.01-0.24), and the composite (OR, 1.82; 95% CI, 1.0-3.2) were better in SPIRIT than controls, but patient decisional conflict did not differ between groups (β=-0.01; 95% CI, -0.12 to 0.10).Secondary Outcomes45 patients died during the study. Surrogates in SPIRIT had less anxiety (β=-1.13; 95% CI, -2.23 to -0.03), depression (β=-2.54; 95% CI, -4.34 to -0.74), and posttraumatic distress (β=-5.75; 95% CI, -10.9 to -0.64) than controls.LimitationsStudy was conducted in a single US region.ConclusionsSPIRIT was associated with improvements in dyad preparation for end-of-life decision making and surrogate bereavement outcomes.Copyright © 2015 National Kidney Foundation, Inc.
