Epistemic Injustice in Marginalised Patient Populations: Reconceptualising Health Inequities Through the Lens of Social Epistemology

This paper examines epistemic injustice in healthcare settings and its implications for health services research and clinical practice. Epistemic injustice, the systematic devaluation of patients' knowledge and experiences, particularly affects marginalized populations. Drawing on empirical studies and theoretical literature, we analyse how this phenomenon manifests in clinical encounters, impacts health outcomes, and perpetuates health disparities. Our findings indicate that epistemic injustice contributes to misdiagnosis, delayed treatment, and reduced patient engagement, ultimately affecting healthcare quality and effectiveness. We explore the implications for patient-centred care, health equity, and quality improvement, discussing how recognizing epistemic injustice can inform research methodologies, clinical guidelines, and healthcare policy. Potential mitigation strategies are identified, including enhanced clinician training and more inclusive approaches to medical knowledge production. This work provides health services researchers, clinicians, and policymakers with insights into the dynamics underlying health inequities and suggests pathways for creating more equitable healthcare systems.
