Virtual reality for relaxation in intensive care unit patients: feasibility, acceptability and intervention adaptation.
Article in Pilot and feasibility studies, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLess sedation has become the standard regimen in patients admitted to an intensive care unit. Consequently, conscious patients experience discomfort and anxiety during their admission. Virtual reality is used in other hospital settings to distract patients and reduce discomfort and anxiety; however, its acceptability in intensive care has yet to be explored. This study aimed to identify and adapt a virtual reality intervention for relaxation and distraction to meet the specific needs of patients admitted to an intensive care unit, focusing on patients' and nurses' acceptability of the intervention.
methodsThis exploratory study was guided by the Medical Research Council's framework for developing or identifying, evaluating and implementing complex interventions. In the initial phase, combined knowledge from existing literature and experts in virtual reality for healthcare guided the preliminary identification process. Findings from think-aloud interviews with stakeholders guided the final adaptations. The data was analysed using the framework method.
resultsThe combined findings from the literature, stakeholder audit trails and interviews showed consensus that nature films with auditory stimuli were acceptable for inducing relaxation and distraction in critically ill patients, with few or no adverse effects. A key uncertainty regarding virtual reality's effect on delirium or its potential role in delirium development affected nurses' acceptability of virtual reality, highlighting a need to consider this risk.
conclusionsThis intervention identification, adaptation, acceptability and feasibility study concludes that virtual reality for relaxation and distraction is an acceptable intervention in the intensive care unit setting. The identified and adapted virtual reality software intervention was a 10-min 360-degree natural beach film combined with nature sounds and calming music. The identified hardware intervention was a headset connected to a tablet, enabling nurses to control the software. A subsequent study should examine the preliminary short effectiveness and adapt the intervention according to the further findings.
