EMPOWER: A Multi-Site Pilot Trial to Reduce Distress in Surrogate Decision-Makers in the ICU

Context: Efforts to reduce the psychological distress of surrogate decision-makers of critically ill patients have had limited success, and some have even exacerbated distress.

Objectives: The aim of this study was to determine the feasibility, acceptability, and preliminary efficacy of EMPOWER (Enhancing and Mobilizing the POtential for Wellness and Resilience), an ultra-brief (∼2-hour), 6-module manualized psychological intervention for surrogates.

Methods: Surrogates who reported significant anxiety and/or an emotionally close relationship with the patient (n=60) were randomized to receive EMPOWER or enhanced usual care (EUC) at one of three metropolitan hospitals. Participants completed evaluations of EMPOWER's acceptability and measures of psychological distress pre-intervention, immediately post-intervention, and at 1- and 3-month follow-up assessments.

Results: Delivery of EMPOWER appeared feasible, with 89% of participants completing all 6 modules, and acceptable, with high ratings of satisfaction (mean=4.5/5, SD = .90). Compared to EUC, intent-to-treat analyses showed EMPOWER was superior at reducing peritraumatic distress (Cohen's d = -0.21, small effect) immediately post-intervention and grief intensity (d = -0.70, medium-large effect), posttraumatic stress (d = -0.74, medium-large effect), experiential avoidance (d = -0.46, medium effect), and depression (d = -0.34, small effect) 3 months post-intervention. Surrogate satisfaction with overall critical care (d = 0.27, small effect) was higher among surrogates randomized to EMPOWER.

Conclusions: EMPOWER appeared feasible and acceptable, increased surrogates' satisfaction with critical care, and prevented escalation of posttraumatic stress, grief, and depression 3 months later.
