Clinical Frailty Scale (CFS)

The Clinical Frailty Scale grades an older person’s overall fitness or frailty from 1, very fit, to 9, terminally ill. It’s a clinical judgment of how they moved, managed daily life, thought, and felt in the two weeks before an illness, not a questionnaire.

What the score means. 1 to 9, level.

1 to 3: Not frail

Very fit, fit, or managing well: independent, with any conditions under control. The person has reserve to recover; plan care around the illness itself.

4: Living with very mild frailty

Not dependent on others, but slowed down or limited by symptoms. Review medicines, activity, and falls, and rescore after any illness.

5 to 6: Mild to moderate frailty

Needs help with some daily activities. Expect more complications, delirium, and a slower recovery; consider a geriatric assessment and talk about goals of care early.

7 to 9: Severe frailty to terminally ill

Dependent for personal care, near the end of life, or terminally ill. Recovery from a major illness is less likely, so goals of care and comfort lead the conversation, with the level as one input, never the decision.
  • The CFS is a clinical judgment, not a sum of answers. Choose the one level that best fits the person, using the descriptions and pictures on the official version 2.0.
  • Score the baseline: how the person was about two weeks before the acute illness began, not how they look today. Level 9 is the only exception; it’s scored on the current state.
  • The levels in plain words: 1 very fit, 2 fit, 3 managing well, 4 living with very mild frailty, 5 mild frailty, 6 moderate frailty, 7 severe frailty, 8 very severe frailty, and 9 terminally ill.
  • Most studies and guidelines count a level of 5 or more as frail. Some use 4 or more, and 7 or more is usually called severe frailty; say which grouping your service uses, and record the level itself.
  • Level 9 is for people with a life expectancy under about 6 months who aren’t otherwise severely frail. A severely frail person who is dying is scored on their frailty, usually 7 or 8.
  • In dementia, the level usually follows the stage: mild dementia fits level 5, moderate level 6, and severe level 7.
  • The CFS was built and validated in people 65 and older. It isn’t validated in younger adults, and it’s not meant for disability from one stable condition, such as a spinal cord injury, cerebral palsy, or a learning disability. Describe function there instead of giving a level.
  • Higher levels predict death, moving into long-term care, complications, and longer hospital stays. In the original 2005 study, each step up the scale raised the medium-term risk of death by about 21%.
  • Version 2.0, from 2020, renamed some levels: level 2 from “well” to “fit,” level 4 from “vulnerable” to “living with very mild frailty,” and levels 5 to 8 to “living with” mild, moderate, severe, and very severe frailty. Older records may use the old names.

How to give it, score it, and read it.

Finding the baseline

Score the person as they were about two weeks before they became unwell. Acute illness makes fit people look frail, and few people recover beyond where they were then.

  • Ask how the person was doing two weeks before this started, or ask someone who knows them
  • When the person can’t tell you, speak with a partner, a son or daughter, care home staff, or a home care worker
  • Use records too: recent clinic letters, home care hours, and therapy notes
  • For a planned visit with no acute illness, score the current usual state

Avoid: Scoring the person in the bed. A confused, bedbound patient with pneumonia may have been walking to the shops two weeks ago.

Asking about four things

The developers’ guidance asks how the person moved, managed daily activities, thought, and felt about their health over those two weeks.

  • Mobility: walking aid, how far, stairs, getting out of a chair, and falls
  • Function: housework, shopping, money, medicines, and transport, then bathing, dressing, and toileting
  • Cognition: memory, a dementia diagnosis and its stage, and any recent confusion
  • Health: the main conditions, how well symptoms are controlled, the medicine list, how active the person is, and how they rate their health against people their age

Avoid: Counting a task the person never did as a loss. Someone whose spouse has always done the banking isn’t dependent for it now.

Choosing the level

Match what you’ve learned to the official descriptions and pick the one level that fits best. It takes judgment, not arithmetic.

  • Mobility, function, and cognition decide most levels from 4 to 7
  • Most people fit one level well; when two fit equally, choose the higher
  • In dementia, let the stage guide the level: mild 5, moderate 6, severe 7
  • Keep level 9 for terminal illness with a life expectancy under about 6 months in someone not otherwise severely frail
  • When unsure, ask a colleague whose judgment you trust

Avoid: Writing down whatever the patient says. The level combines what you hear, what you see, and what people who know the person tell you.

Who it fits

The CFS measures the frailty that builds up with age. It was developed and validated in people 65 and older.

  • Use it for older adults on admission, before surgery, and in emergency and geriatric care
  • In adults under 65, use it with caution and never on its own; it’s largely unvalidated there
  • Don’t give a level for disability from one stable condition, such as a spinal cord injury, cerebral palsy, or an intellectual disability; describe function instead
  • Record why you did or didn’t score it

Avoid: Turning a lifelong disability into a high frailty level. It doesn’t carry the prognosis that frailty from aging does.

Using the level

The level informs prognosis, goals of care, and planning, together with how sick the person is now and what they want.

  • Prognosis: recovery depends on both the baseline level and the severity of the acute illness; the bigger the drop from baseline, the harder the way back
  • Goals of care: use it to open an honest talk about what recovery may look like and what matters most to the person
  • Surgery: a level of 5 or more flags a higher risk of complications, delirium, and discharge to a care facility; plan prehabilitation, geriatric input, and discharge early
  • Discharge: compare the level at discharge with the baseline to plan rehabilitation and support at home
  • Rescore after recovery, or whenever function changes

Avoid: Using the level as the only reason to withhold treatment, intensive care, or resuscitation. It’s one input to a decision made with the person, never the decision.

CFS result: level 6 on admission with pneumonia, guiding goals of care

Medical ward, first day of admission from the emergency department

Baseline

Her usual state two weeks before the cough began. Information from her daughter, who visits most days, and the home care agency’s care plan. The patient is drowsy and confused today and couldn’t give a history.

Level

CFS 6, living with moderate frailty, on version 2.0. Group: mild to moderate frailty. Today she looks like an 8: in bed, needing help to turn and to drink, with delirium. That is the pneumonia, not her baseline.

Reasons for the level

84-year-old woman living alone in a ground-floor apartment. Daily activities: her daughter does the shopping and banking, meals are delivered, and an aide helps her shower twice a week; she dresses and uses the toilet on her own. Mobility: walker indoors, no longer goes out alone, one fall in the summer. Cognition: mild Alzheimer’s disease for 2 years, on donepezil. Conditions: heart failure with preserved ejection fraction, atrial fibrillation on apixaban, and knee osteoarthritis; 9 regular medicines.

Use in the plan

Talked through with her daughter, her named decision-maker, alongside a CURB-65 of 3 and what she told her family doctor last year about not wanting life support. Agreed: IV antibiotics, oxygen, and fluids on the ward; no intensive care, intubation, or CPR. Delirium care started. Physical and occupational therapy from day 2. Rescore before discharge; more home support likely.

Common mistakes, and how to avoid them.

Scoring today instead of the baseline

An acute illness can make a level 3 look like a level 7. Score how the person was two weeks before it began, and say where that information came from.

Skipping the people who know them

A confused or very ill patient can’t give a reliable baseline. Ask family, carers, or care home staff, and check the records.

Using it outside the group it was built for

In younger adults and in people with one stable disability, a high level doesn’t carry the prognosis it does in age-related frailty. Describe their function instead.

Letting the level make the decision

The CFS informs prognosis and goals of care. Decisions about intensive care, surgery, or resuscitation also need the acute illness, the options, and what the person wants.

Recording only the number

A bare “CFS 6” can’t be checked or compared later. Note the baseline date, the source, and the function, mobility, and cognition behind the level.

Frequently asked questions.

What is the Clinical Frailty Scale?

It’s a 9-level scale that sums up an older person’s overall fitness or frailty, from 1, very fit, to 9, terminally ill. A clinician chooses the level after assessing the person, using judgment and what the person and their family report. Dr. Kenneth Rockwood and colleagues at Dalhousie University published it in 2005; the current version, 2.0, came out in 2020.

How do you score the Clinical Frailty Scale?

There’s nothing to add up. Find out how the person moved, managed daily activities, thought, and felt about their health about two weeks before any acute illness, from them and from someone who knows them. Then pick the level on the official scale that fits best; if two fit equally well, choose the higher one. Level 9 is the only level scored on the person’s current state.

What CFS score means frail?

Levels 1 to 3 are not frail, level 4 is living with very mild frailty, and 5 or more is the usual cutoff for frailty: 5 mild, 6 moderate, 7 severe, 8 very severe, and 9 terminally ill. Some studies and services count 4 or more as frail, so record the level itself, not only “frail” or “not frail.”

Can the Clinical Frailty Scale be used in people under 65?

It was developed and validated in people 65 and older, and it’s largely unvalidated in younger adults, so use it there with caution and never on its own. It shouldn’t be used for disability from one stable condition, such as a spinal cord injury, cerebral palsy, or a learning disability, because a high level wouldn’t mean the same thing for prognosis.

How do you score the CFS in someone with dementia?

The level usually follows the stage of dementia: mild dementia fits level 5, moderate level 6, and severe level 7. Use the stage at baseline, not the confusion of a delirium from a new illness, and still check function and mobility, which can place the person higher.

How is the CFS different from a frailty index or the frailty phenotype?

A frailty index counts health problems from a long list and divides by the number checked, for a score from 0 to 1. The frailty phenotype measures five things: weight loss, exhaustion, low activity, slow walking, and weak grip. The CFS is quicker than both: one clinical judgment with no equipment, which is why emergency and hospital teams use it.

Who can score the CFS?

The developers’ guidance says any licensed or registered health care professional who has assessed the person, such as a physician, nurse, occupational or physical therapist, social worker, or psychologist. New raters can check their scores with the classification tree on the official site, and with an experienced colleague when unsure.

Is the Clinical Frailty Scale free, and where do I get it?
