Clinical Frailty Score

1Very fitPeople who are robust, active, energetic, and motivated. These people commonly exercise regularly. They are among the fittest for their age.
2WellPeople who have no active disease symptoms but are less fit than category 1. Often, they exercise or are very active occasionally, for example, seasonally.
3Managing wellPeople whose medical problems are well controlled, but are not regularly active beyond routine walking.
4VulnerableAlthough not dependent on others for daily help, often symptoms limit activities. A common complaint is being “sloped up” and/or being tired during the day.
5Mildly frailThese people often have more evident slowing and need help in high-order instrumental activities of daily living (finances, transportation, heavy housework, medications). Typically, mild frailty progressively impairs shopping and walking outside alone, meal preparation, and housework.
6Moderately frailPeople need help with all outside activities and with keeping house. Inside, they often have problems with stairs and need help with bathing and might need minimal assistance (cuing, standby) with dressing.
7Severely frailCompletely dependent for personal care, from whatever cause (physical or cognitive). Even so, they seem stable and not at high risk of dying (within ~6 months).
8Very severely frailCompletely dependent, approaching the end of life. Typically, they could not recover from a minor illness.
9Terminally illApproaching the end of life. This category applies to people with a life expectancy <6 months, who are not otherwise evidently frail.
