Episodes of (Dis)Connected Consciousness Among Patients Who Survived a Critical Illness

What this trial studies

This is a single-center observational study at CHU de Liège enrolling adults who survived at least seven days in the ICU and experienced at least one pharmacological or non-pharmacological loss of consciousness. Participants complete the Near-Death Experience Content (NDE-C) scale, a threat perception measure, and an interview about memories of their ICU stay. Investigators will describe the incidence of connected and disconnected consciousness episodes, analyze clinical risk factors, and perform a six-month follow-up to explore longer-term psychological outcomes. Data collection is descriptive and hypothesis-generating rather than interventional.

Who should consider this trial

Good fit: Adults who speak French, survived at least seven days in an intensive care unit, and experienced at least one pharmacological or non-pharmacological coma episode are the ideal candidates.

Not a fit: Patients with chronic disorders of consciousness, ongoing confusion or delirium, significant deafness, blindness, aphasia, or those who refuse participation are unlikely to benefit from this observational project.

Why it matters

Potential benefit: If successful, the findings could help clinicians recognize and address psychological distress and long-term mental-health needs in ICU survivors who report near-death or out-of-body experiences.

How similar studies have performed: Previous observational reports have described near-death and out-of-body experiences after cardiac arrest and critical illness, but systematic data specifically after prolonged ICU stays remain limited.
