Surgery for Older Adults: Frailty, Delirium and Goals of Care
Surgery for Older Adults: Protecting Mind and Body
Age alone is a poor guide to surgical risk. Two people of the same age can have very different reserves. The more useful question is frailty: how well your body and mind can withstand the stress of an operation and recover afterward. This guide is for older patients and the families who support them. Its promise, in the words of the book: we plan around what matters most to you and your family, and we work hard to protect your mind as well as your body.
Frailty, Not Just Age
- Before planned surgery, the team assesses frailty, memory and thinking, day-to-day function, and nutrition, and asks about your own goals. A simple scale grades fitness from 1 (very fit) to 9 (terminally ill), based on what you can do, not on your diagnoses.
- Expect questions like: tell me about a typical day; what do you do for yourself, what help do you need, and how do you get around? Have you had confusion, memory problems, or falls recently? What matters most to you about this operation and your recovery?
- Many risks can be reduced with preparation: treating poor nutrition, reviewing medicines, and planning the ward care before you arrive.
Delirium: The Confusion That Can Follow Surgery
Sometimes after an operation, older patients become confused for a while: muddled, seeing things that are not there, or unusually sleepy or agitated. This is called delirium. It is common, frightening to watch, and almost always temporary. It is not the same as dementia, though it is more likely in someone who already has memory problems. It can affect up to about 1 in 5 frail patients after major surgery, and more often with greater frailty. Family members often notice the change first, because they know the patient's usual self. Tell the nurses at once if your relative seems different from usual.
Preventing Delirium: What Helps
- Glasses and hearing aids: make sure they travel with the patient and are worn, not left at home.
- Familiar things and people: family presence, photographs, and familiar objects help. Families are welcome; your presence is part of the treatment.
- Orientation: gently remind the person of the day, time, and where they are.
- Movement: getting out of bed early, with support, protects both mind and body. Falls risk is managed by supporting movement, not by preventing it.
- Sleep and routine: a normal day-night routine, with sleep protected at night.
- Food and fluids: encourage regular meals and enough to drink.
- Treating triggers quickly: pain, constipation, difficulty passing urine, and infection can each trigger or worsen delirium, so report them early.
- Medicines review: sedating medicines, especially benzodiazepines, and bladder catheters and physical restraints are minimised, because each increases delirium risk.
Your Wishes Come First: Family and Goals of Care
Family involvement is welcome and protective, but the patient's own wishes come first. If you have capacity, you decide who is involved and how much is shared, even if your family is present and vocal. Some older patients prefer their children to decide; others wish to decide themselves. The team will ask you directly.
For major or high-risk surgery, a goals-of-care conversation is part of good consent: what matters most to you, such as living as long as possible, remaining independent, avoiding intensive care or a breathing machine, or comfort. Tell the team if you have an advance directive or a preferred decision-maker, and what should happen if a major complication occurs. These conversations happen before surgery, calmly, so that everyone can act according to your wishes.
Recovery After Surgery: What to Expect
- Recovery may be slower than for a younger person; this is normal. Strength and independence are rebuilt gradually, with support if needed.
- Mild tiredness or slower thinking can happen for a few days and should improve.
- Most people who develop delirium recover fully over days to weeks, though recovery can take longer in people who already had memory problems.
- At home: keep walking aids, glasses, and hearing aids close by; clear rugs and clutter to prevent falls; eat regular meals and drink enough; take medicines exactly as prescribed.

Questions Patients and Families Ask
Is my relative too old for this operation?
Age alone does not decide this. We look at fitness, independence, and other health problems, and we will be honest about the risks and benefits for this specific person.
Why did my mother become confused after the operation?
This is called delirium. It is common after surgery in older adults, is usually temporary, and the team is treating the cause and supporting her through it.
Will the confusion be permanent?
Usually not. Most people recover fully over days to weeks, though recovery can take longer in people who already had memory problems.
Can I stay with my relative in hospital?
Yes, where possible. Family presence helps prevent and ease delirium, and we welcome it.
Should we decide as a family, or should Mum decide?
We follow what your mother wants. If she has capacity, the decision, and how much to involve you, are hers to make.
