Despite its widespread use, the KPS has limitations: - Subjectivity: The assessment can be subjective, varying between different evaluators. - Non-specificity: The KPS does not account for the specific types of functional impairments or the reasons behind them. - Static Nature: The scale does not capture changes over short periods, which can be crucial in rapidly progressing diseases. - Patient Perspective: It lacks the patient’s perspective on their own quality of life and functional status.
