Reducing Isolation and Loneliness in Patients With Critical Illness With Novel Engagement Strategies: a Pilot Randomized Trial

Patients with critical illnesses such as sepsis and acute respiratory failure (ARF) who require an ICU stay are at high risk of developing anxiety, depression, post-traumatic stress disorder, and cognitive deficits. Risk factors for emotional and cognitive impairments after ICU include underlying systematic illness, as well as consequences of life-saving therapies. In brief, patients are frequently restricted and even restrained to the bed, provided high dosages of sedatives, develop delirium, and are isolated from family and staff for extended periods of time. Moreover, the ICU environment including lights, noises, and the social isolation have a serious negative impact on cognitive function and emotional health status. Prospective data from the ICU demonstrate that critically ill patients in ICU spend two-thirds of their time completely alone.

Patients who have survived describe their ICU experience as a traumatic event similar to war, and testimonials for the ICU Recovery clinic frequently resemble: "I felt like I was being held captive in an unknown basement." Periods of social isolation in daily life as well as in the hospital have a significant negative impact on patient-centered outcomes including increased risk of disability, frailty, and mortality. Our study will examine the feasibility of delivering social engagement interventions using technology such as virtual reality (VR) to reduce feelings of isolation and loneliness. There have been a handful of projects to reduce anxiety and depression using a myriad of delivery techniques including journaling in a diary, emotional-behavioral therapy, face-to-face social engagement and family engagement using face-time and VR. These projects, however, have not examined the impact of social engagement on reducing periods of isolation and loneliness. We hypothesize that social engagement delivered using VR technologies will reduce periods of social isolation and thus improve anxiety, depression, and post-traumatic stress disorder (PTSD).
