Leaving the ICU is not the end
People who go through intensive care often leave with more than the illness that brought them in. Loose memories, dreams that felt real, trouble making sense of the days under sedation. Some of them develop anxiety, depression or post-traumatic stress symptoms in the following months. It is one side of what is called post-intensive care syndrome.
One idea being tested is to use virtual reality after discharge to explain what an ICU is: the ventilator, the monitors, the alarms, the team's routine. Understanding what happened may help put memories in order.
The trial
In July 2026 Critical Care published a three-arm randomised trial run in 11 hospitals in the Netherlands and Belgium (Drop and colleagues). It included 344 former ICU patients, median age 61.
- One group received usual care.
- Another watched a 14-minute 360° video, filmed in each hospital's own ICU, 7 to 15 days after leaving the ICU (one to three viewings).
- The third watched the same video once, about three months later, at the follow-up clinic.
The main outcome was the severity of post-traumatic stress symptoms at six months.
What they found
- No difference in post-traumatic stress between either video group and usual care.
- No difference in anxiety, depression or quality of life either.
- Comparing the two video groups, those who watched earlier had better quality of life scores at six months than those who watched later.
- Patients liked the video. They gave it a median of 8 out of 10 for helping them understand what had happened.
The authors write that these results should not be generalised to multi-session, therapist-guided or personalised interventions.
Why we publish a neutral result
Because that is how evidence works, and because people buying or using virtual reality in healthcare deserve to know what did not work as well as what did. A well-run trial with hundreds of patients saying that a short, informational intervention is not enough to change mental health six months later is valuable information.
There is also a practical reading. The video in this study was educational: it showed the ICU. It was not a calm moment, a conversation or a place chosen by the person. And it was watched one to three times. Much of the use of VR on the ward is something else: short, repeated sessions, led by carers, to ease difficult moments of the day. One neither proves nor disproves the other.
What stays
If the question is whether an explanatory video after discharge prevents post-traumatic stress, this trial says no. If the question is whether patients value understanding what happened to them, it says yes. And if the question is about VR during the hospital stay, that is a different topic, covered in delirium in intensive care and the cost of immobility in hospital.
RVer is used by clinical teams in contexts of anxiety and inpatient care, always led by a professional. It is not used or presented as a treatment for post-traumatic stress.
Frequently asked questions
Does virtual reality prevent post-traumatic stress after the ICU?
In a 344-patient trial, an informational 360° ICU video did not reduce symptoms at six months.
Did patients like it?
Yes. They gave it a median of 8 out of 10 for helping them understand their stay.
Does this result apply to any use of VR?
No. The authors say it should not be generalised to multi-session, guided or personalised interventions.
