The Katz ADL Scale is a tool used to assess an individual's ability to perform basic daily activities. It evaluates six key functions: bathing, dressing, toileting, transferring, continence, and feeding. Each activity is scored as either independent or dependent, helping healthcare professionals understand a person's level of independence. This scale is particularly useful in settings like hospitals and nursing homes, where understanding a patient's functional abilities is crucial for care planning. By identifying areas where assistance is needed, caregivers can tailor support to improve the individual's quality of life and promote greater autonomy.
