This chapter examines ableism as a structural and often invisible form of discrimination embedded within healthcare systems. Using a concept analysis framework, ableism is defined through its attributes, antecedents, and consequences, including diagnostic overshadowing and exclusionary practices (Nami, Ableism: a concept analysis in nursing. Unpublished manuscript. University of Missouri–Kansas City, 2025; Buettner-Schmidt, Lobo, J Adv Nurs 68(4):948–958. https://doi.org/10.1111/j.1365-2648.2011.05856.x , 2012). This chapter contrasts the medical and social models of disability, emphasizing the importance of shifting toward disability justice and inclusivity in nursing care. Intersectionality is explored to highlight compounded inequities faced by disabled individuals across race, gender, and socioeconomic status. This chapter concludes by advocating for anti-ableist reforms in nursing education, policy, and practice to ensure equitable and patient-centered care.
