A Pilot Randomized Controlled Trial Assessing the Feasibility and Acceptability of Family-Partnered Delirium Prevention, Detection, and Management in Critically Ill Adults: The Activating Family Caregivers in the Identification Prevention and Management of Delirium (ACTIVATE) Study.

OBJECTIVES BACKGROUND

Delirium remains frequently undetected by healthcare providers; partnering with family may be a novel way to identify and manage delirium. This study explores the feasibility of a family-administered intervention for delirium prevention, detection, and management.

DESIGN

Pilot randomized controlled trial.

SETTING

Two Canadian ICUs.

SUBJECTS

Patient-family pairs (dyads) were included. Eligible patients had no primary brain injury, a Richmond Agitation-Sedation Scale score of greater than or equal to -3, and were expected to remain in the ICU for at least 24 hours to complete all study assessments.

INTERVENTIONS

Dyads were randomly assigned to either standard care (control) or the intervention, which included delirium education and family-administered checklists with prevention/management strategies and a detection tool ("Sour Seven").

MEASUREMENTS AND MAIN RESULTS

Outcomes included feasibility indicators, enrollment and completion rates, and psychological outcomes (Generalized Anxiety Disorder-7, Patient Health Questionnaire-9, and the Kessler Psychologic Distress (K-10) scales in the ICU and at 1- and 3-month follow-ups. Between January 2020 and June 2023, during the height of the COVID pandemic, 197 patient-family pairs were approached, with 64 (32%) consenting to participate; participation required both the patient and a family member. Despite recruitment challenges, 75% of families completed in-ICU questionnaires, and 38% completed all follow-ups. The family members in the intervention group demonstrated increased delirium knowledge compared with baseline delirium knowledge, and engagement in prevention strategies, with 8 of 19 (42%) family members identifying delirium using the Sour Seven. At the 3-month follow-up, seven family members showed significant anxiety, and five showed significant depression. Observations of ICU rounds revealed limited delirium discussions.

CONCLUSIONS

This pilot study demonstrated the feasibility of family-administered delirium care in ICU settings. However, the likely impact of the COVID-19 pandemic cannot be overlooked. The study faced recruitment challenges and demonstrated the difficulties of family involvement in delirium care, particularly during restricted family presence. A full evaluation of effectiveness requires a hypothesis-testing trial with procedural adjustments to streamline data collection and strengthen family-care team partnerships.
