Abstract Rehabilitation of people who are critically ill has received increased attention in recent years, although this has not extended to specifically facilitating family involvement. Engaging families in the rehabilitation arc has the potential to optimize outcomes. Likely benefits include redirecting family psychological distress into an active participatory role, humanizing the patient illness and recovery experience, and supporting staff and the health care system beyond the constraints of therapy time. This viewpoint explores why families should be engaged in critical care rehabilitation, gives an overview of the evidence for family participation in bedside care, and provides practical implementation strategies and signpost areas for future research.
