Sometimes. Delirium is common near the end of life. It also occurs in people who go on to recover. Delirium alone does not tell you whether someone is dying.
How to tell the difference
The team needs to look at the person’s overall condition. What is causing the delirium? Which problems can be treated? Is the person getting better, staying much the same, or becoming more unwell despite treatment? Sometimes the answer becomes clearer over several days.
Even when someone has an advanced illness, new delirium needs assessment. There may be something the team can treat, such as pain, an infection, a medicine causing problems, or a full bladder that the person is unable to empty.
Ask directly
You can ask: “Do you think they may be dying? What makes you think that? Is there still a chance they will recover from this illness?”
If the team is uncertain, ask what they will be watching for and when they will review the situation. Ask who you should contact if the person changes or seems distressed.

When to get help
If there is an agreed plan for care at the end of life, follow it and contact the named hospice, palliative care or primary care team urgently about new confusion or distress. In a hospital or care home, tell staff immediately.
If there is no such plan, delirium (acute confusion) at home needs emergency medical help: phone local emergency services. If there is a plan but you are unable to get urgent help through it, and the person is seriously unwell or getting worse, phone local emergency services and tell them about the plan.
