Despite its utility, the KPS has some limitations:
1. Subjectivity: The assessment can be somewhat subjective, as different clinicians may interpret levels of functioning differently. 2. Non-Specific: It does not provide information on specific functional abilities or symptoms, focusing instead on overall performance status. 3. Static Nature: The scale may not capture rapid changes in a patient’s condition, as it is often used at single points in time rather than continuously.
