Despite its strengths, the Katz Index has some limitations:
1. Limited Scope: It only evaluates basic ADLs and does not assess more complex activities, like instrumental activities of daily living (IADLs). 2. Subjectivity: The assessment can be subjective, depending on the nurse’s judgment and the patient’s cooperation. 3. Not Comprehensive: May not capture the full extent of a patient’s abilities or impairments, especially in cases of cognitive decline.
