What is a Frailty Index?

A Frailty Index is a tool used in geriatric medicine to quantify the health status of older individuals by measuring their vulnerability to adverse health outcomes. It is calculated by assessing a range of health-related variables, including physical and cognitive impairments, illnesses, and disabilities. The higher the score on the Frailty Index, the more frail the individual is considered to be, indicating a higher risk of mortality, hospitalization, and other negative health events.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Frailty Index:

\[ \text{FI} = \left( \frac{5}{40} \right) \times 100 = 12.5\% \]

The Frailty Index is 12.5%.
