The short answer
- Frailty is about reserve, not ageIt describes how well somebody recovers from an illness, an infection or a fall. Two people of the same age can be in very different places.
- The GP and the hospital use different scoresGP records use the electronic Frailty Index. Hospitals use the Clinical Frailty Scale, a nine-level scale scored by a clinician.
- A score should lead to a reviewFor severe frailty, GP practices are required to review medicines each year and ask about falls. Hospitals may offer a fuller assessment.
- Frailty can changeNHS and specialist sources say activity, good food and the right support can make it a little better.
This page explains the terms for a family. It is not a medical assessment, and your parent's GP or hospital team is the right place to ask about their own score.
What frailty is
Frailty describes how much reserve somebody has
Frailty is the word doctors use when somebody has less in reserve than they used to, so a small illness or a fall knocks them further and it takes longer to get back to where they were.
Age UK describes frailty as a person's ability to bounce back and recover from events like illness and injury. In somebody living with frailty, a problem that sounds minor, such as a urinary infection, can have a large and lasting effect on how they manage. NHS England says it raises the risk of falls, delirium and loss of independence.
It is more common as people get older, but Age UK is clear that it is not inevitable, and that somebody living with frailty can still lead a full life. It is also not one illness. It builds up from several things at once: weaker muscles, tiredness, long-term conditions, several medicines, poorer eating and less activity. That is why the response to it looks at the whole person rather than one condition. The mobility and falls care guide covers the wider picture of staying steady at home.
Words you may hear from the GP or hospital
- Frailty
- Having less reserve to recover from illness, injury or a stressful event. Described as mild, moderate or severe.
- eFI
- The electronic Frailty Index. A score worked out automatically from the GP record, used to spot people who may be living with frailty.
- Clinical Frailty Scale
- A nine-level scale a clinician uses to describe how somebody was managing before they became unwell. Sometimes called the Rockwood scale.
- CGA
- Comprehensive geriatric assessment. A thorough review by a team who look at health, medicines, mood, memory, mobility, home and what matters to the person.
- Medication review
- A GP or pharmacist going through every medicine to check it is still needed and not causing side effects such as dizziness.
The two scores
The frailty index in GP records and the frailty scale in hospital
Families hear about frailty in two places, and each one uses a different tool. Knowing which one was used tells you what the words mean.
| Electronic Frailty Index (GP) | Clinical Frailty Scale (hospital) | |
|---|---|---|
| Who uses it | GP practices, for patients aged 65 and over | Hospitals and community teams, for people aged 65 and over |
| How it is worked out | Automatically, by counting health problems already in the GP record | By a clinician, from talking to your parent and the family |
| What it gives | Fit, or mild, moderate or severe frailty | A level from 1, very fit, to 9 |
| What it is for | Finding people who should be offered a medication review and a falls check | Planning care and deciding who needs a fuller assessment |

The electronic Frailty Index looks for 36 kinds of problem in the GP record, such as conditions, symptoms, disabilities and test results. The more it finds, the more likely it is that somebody is living with frailty. Because it only reads the record, it is a flag for the GP to look more closely rather than a diagnosis. Since 2017, the GP contract has asked practices to identify patients aged 65 and over living with moderate and severe frailty each year, and the eFI is one of the tools they can use.
The Clinical Frailty Scale was developed by Kenneth Rockwood and colleagues at Dalhousie University in Canada. In England, NHS England's guidance for hospital frailty services asks for a score within 30 minutes of arrival for people aged 65 and over. The scale is meant to describe how your parent was two weeks before they became unwell, not how they look in a hospital bed, so the staff will ask you what they could do at home. Your answer matters, so be specific about what they managed alone and what they needed help with.
The levels
What each level of the Clinical Frailty Scale broadly means
The scale runs from 1, very fit, to 9. The descriptions below are in our words, and the help beside each one is a general guide for families rather than part of the scale.
- Levels 1 to 3
Very fit, fit, or managing well
What it looks like
Gets on with life without help. Any health conditions are under control, even if they are less active than they were.
Help that tends to fit
No care needed. Staying active and keeping up with check-ups helps keep things this way.
- Level 4
Living with very mild frailty
What it looks like
Still does everything for themselves, but feels slowed up or tired in the day, and some things take longer.
Help that tends to fit
Strength and balance exercise, a check of their medicines, and a family member keeping an eye on how they are doing.
- Level 5
Living with mild frailty
What it looks like
Needs help with the bigger jobs outside the home: money matters, getting to places, heavy housework, and sometimes shopping.
Help that tends to fit
Lifts to appointments, help with the shopping and the heavier chores, and perhaps a few hours a week of company or practical help.
- Level 6
Living with moderate frailty
What it looks like
Needs help with everything outside the home and with keeping house. Stairs may be hard, and they may need help with bathing and some prompting with dressing.
Help that tends to fit
Regular visits for shopping, meals and housework, help with washing, and a falls assessment. Ask whether a fuller assessment by an older people's team is right.
- Level 7
Living with severe frailty
What it looks like
Needs help with washing, dressing and other personal care, whether the cause is physical or memory and thinking, but is otherwise settled.
Help that tends to fit
Help at home every day, which may mean more than one visit a day, with equipment advice from an occupational therapist. Live-in care is worth weighing up if visits stop covering the day.
- Levels 8 and 9
Very severe frailty, or a serious illness
What it looks like
Needs help with everything, or has an illness that is expected to shorten life.
Help that tends to fit
The GP or hospital team plans care with the family, and it can include community nurses and specialist support alongside care at home.
A general guide only. Only a clinician who has assessed your relative can give them a score, and it describes how they were before any recent illness. The help that fits depends on the person, and on what matters to them.
Hospitals use the level alongside everything else they know about your parent. It helps staff plan the right care on the ward, and it is one of the things doctors weigh up when they talk with you about treatment. The scale's authors say scoring it needs clinical judgement, and NHS England's hospital guidance asks staff to help patients understand the options, risks and benefits of their care. If you are unsure how a score is being used, ask the doctor to explain it. It is a reasonable question, and a good team will welcome it.
If your parent has made an advance decision or advance statement about their care, tell the ward, because what matters to them is part of the plan.
What happens next
The reviews and help a frailty score should lead to
A score on its own does nothing. What matters is the help that follows it, and the steps below are the ones the NHS guidance names.
- 1
A review of their medicines
GP or pharmacistFor patients with severe frailty, GP practices are required to review medicines every year. Some medicines add to dizziness and falls, and the NHS advises speaking to a GP or pharmacist if you think a medicine is affecting balance. - 2
A check on falls
GP, then a falls serviceThe practice should ask whether your parent has fallen in the last year. A fall, or being worried about falling, is a reason to ask for a referral to the local falls service. - 3
A fuller assessment for some
Older people's teamNHS England says people with moderate frailty benefit from a comprehensive geriatric assessment, and its hospital guidance asks for one for people who score 6 or more. - 4
A look at eating and weight
GP or dietitianLosing weight without trying is a sign of malnutrition, and the NHS says it is not an inevitable part of getting older. The GP can check it and refer to a dietitian. - 5
A care and support plan
With your parentNHS England describes a plan built around what is important to the person, drawing on the family, carers and community services as well as the NHS.
The medication review and falls question come from the GP contract requirements for severe frailty. For moderate frailty, coding and review are left to the clinician. Cambridge University Hospitals explains what a comprehensive geriatric assessment involves for patients and carers: the team gathers information from your parent and the family and looks at all of their health problems together.
If the council has not yet looked at what help your parent needs day to day, ask for a care needs assessment. It is separate from the NHS reviews and is free to ask for.
What helps
Frailty can improve with activity, food and the right support
A frailty score describes where somebody is now, and it can change. North Tees and Hartlepool NHS Foundation Trust says frailty may get worse, but the right support can often make it a little better.
Moving every day

Eating enough, with enough protein

Questions to take to the GP
Write them down
The British Geriatrics Society's guidance on managing frailty reports that exercise at home or in groups improves mobility and everyday ability, and North Tees and Hartlepool's frailty advice covers the everyday steps. The NHS activity guidelines for older adults say strength and balance work helps somebody feel steadier and more confident. Physiotherapy at home explains how to get a referral and keep exercises going between visits. If your parent has started doing less because they are afraid of falling, breaking the cycle of fear of falling covers what helps. For food, what happens when older people do not eat enough sets out the signs, and the NHS page on malnutrition explains when to see the GP.
Help at home can support all of this: somebody to walk with, to cook a proper lunch, and to notice if things change. If the score has made you think about what your parent is managing alone, the signs your parent needs help at home are worth reading. When you are ready, you can search for carers near you and compare their rates. Carers on PrimeCarers charge £18 to £25 an hour with our fee included, and agencies charge £28 to £35. Every carer's identity, right to work and enhanced DBS on the Update Service are checked and they are interviewed online, and every visit booked through PrimeCarers is insured. We do not check training or qualifications, so ask a carer about their experience directly.
Questions
Questions families ask about frailty scores
On the Clinical Frailty Scale, moderate frailty is level 6. It usually means somebody needs help with everything outside the home and with housework, may find stairs hard, and may need help with bathing. In GP records, moderate frailty is one of the eFI categories. Either way, it is a reason to ask about a medication review, a falls check and a fuller assessment.
Yes, it can change. With regular activity, enough to eat and the right support, somebody can become stronger and manage more, and a later assessment would reflect that. An NHS trust leaflet puts it plainly: frailty may get worse, but the right support can often make it a little better.
No. The score is one of the things doctors take into account alongside the illness itself and what matters to your parent. The scale's authors say scoring needs clinical judgement. If you are unsure how it has been used, ask the doctor to explain, and tell them about any wishes your parent has recorded.
Ask the GP surgery or the hospital team. Your parent can ask directly, or you can ask with their permission. It helps to know which tool was used, because an eFI category and a Clinical Frailty Scale level are worked out differently.
The eFI counts health problems in the GP record, so it can flag somebody who manages well day to day. It is a prompt for the GP to look more closely rather than a diagnosis. Ask the GP what it was based on and whether a review is needed.
