Nurse-led intervention to improve surrogate decision making for patients with advanced critical illness.

Background: Problems persist with surrogate decision making in intensive care units, leading to distress for surrogates and treatment that may not reflect patients' values.

Objectives: To assess the feasibility, acceptability, and perceived effectiveness of a multifaceted, nurse-led intervention to improve surrogate decision making in intensive care units.

Study Design: A single-center, single-arm, interventional study in which 35 surrogates and 15 physicians received the Four Supports Intervention, which involved incorporating a family support specialist into the intensive care team.
