Virtual Reality to Improve Sequelae of the Postintensive Care Syndrome: A Multicenter, Randomized Controlled Feasibility Study

Psychologic sequelae after critical illness, part of the postintensive care syndrome, significantly decrease quality of life. A robustly effective treatment intervention is currently lacking. Virtual reality has beneficial effects on several non-ICU-related psychologic disorders. The aim of this study was to explore patient-related determinants of ICU-specific virtual reality, such as the timing of patients' self-reported readiness to initiate virtual reality and the number of desired sessions and safety, and to explore the effects of ICU-specific virtual reality on mental health. DESIGN: A multicenter, randomized controlled feasibility study. SETTING: ICU at a university teaching hospital and a secondary care hospital in Rotterdam, The Netherlands. PATIENTS: Consecutive mechanically ventilated patients with sepsis or septic shock. INTERVENTIONS: Patients were randomly assigned (1:1) to receive ICU-specific virtual reality (ICU-specific virtual reality group) or exposure to a nature virtual reality environment (control virtual reality group). MEASUREMENT AND MAIN RESULTS: < 0.01). Six months after exposure, this effect was still present for posttraumatic stress disorder and depression, but not for mental quality of life. CONCLUSIONS: ICU-specific virtual reality is a feasible and acceptable novel intervention that could be used during recovery from an episode of critical illness in the ICU. A future, adequately powered study should confirm whether virtual reality is able to improve mental health and quality of life.
