Despite being a collection of holistic assessment tools, the comprehensive geriatric assessment primarily focuses on the social category of age during the assessment and disregards for example gender. This article critically reviews the standardized testing process of the comprehensive geriatric assessment in regard to diversity-sensitivity. I show that the focus on age as social category during the assessment process might potentially hinder positive outcomes for people with diverse backgrounds of older patients in relation to other social categories, such as race, (...) gender or socio-economic background and their influence on the health of the patient as well as the assessment and its outcomes. I suggest that the feminist perspective of intersectionality with its multicategorical approach can enhance the diversity-sensitivity of the comprehensive geriatric assessment, and thus improve the treatment of older patients and their quality of life. By suggesting an intersectional-based approach, this article contributes to debates about justice and diversity in medical philosophy and advocates for the normative value of diversity in geriatric medicine.
