Clinical Frailty Scale.

Level	Definition
1	Very fit. People who are robust, active, energetic, and motivated. These people commonly exercise regularly. They are among the fittest for their age
2	Well. People who have no active disease symptoms but are less fit than those with level 1. Often they exercise or are very active occasionally (e.g., seasonally)
3	Managing well. People whose medical problems are well controlled but who are not regularly active beyond routine walking
4	Vulnerable. Although these people are not dependent on others for daily help, often their symptoms limit activities. A common complaint is being “slowed up” and/or being tired during the day
5	Mildly frail. These people often have more evident slowing, and need help with high-order instrumental activities of daily living (e.g., finances, transportation, heavy housework, and medications)
6	Moderately frail. People who need help with all outside activities and with housekeeping. Inside, they often have problems with stairs and need help with bathing and might need minimal assistance with dressing
7	Severely frail. Completely dependent for personal care because of any cause (physical or cognitive).
