ABSTRACT
BACKGROUND:
Language barriers in healthcare are often framed as communication challenges or auxiliary service gaps rather than core public health concerns. In multilingual, resource-constrained public health systems, limited language access undermines informed consent, patient safety, dignity, and trust, contributing directly to inequitable maternal health outcomes. There is growing recognition that language access is not peripheral to care delivery but central to ethical and effective health systems.
METHODS:
This study presents a realist-informed synthesis of empirical studies, policy documents, and ethical analyses published between 1995 and 2025. The review examines how language-access interventions, including professional interpreter services, language-concordant care models, and enforceable language policies, function within public-sector maternal health systems. Evidence from low and middle-income countries and comparable under-resourced settings was synthesised to identify key mechanisms and contextual conditions influencing effectiveness. The Dora Nginza Hospital context in South Africa was used as a case lens to interpret findings within a multilingual, resource-constrained public health system.
RESULTS:
The synthesis demonstrates that language-access interventions improve maternal health equity by activating key mechanisms, including enhanced patient comprehension and agency, reduced clinical error, and strengthened ethical practice through meaningful informed consent. However, these benefits were sustained only where language access was institutionalised through policy enforcement, protected budgets, and leadership commitment. In settings where language services relied on ad hoc arrangements or individual clinician goodwill, impacts were inconsistent and vulnerable to systemic pressures such as staff shortages and time constraints.
CONCLUSIONS:
Language access should be recognised as a core public health intervention essential to ethical, safe, and equitable maternal healthcare. Health systems that fail to institutionalise language services risk perpetuating structural inequities and ethical harm. Public health policy and planning must therefore integrate language access into health system design, financing, and accountability frameworks to advance maternal health equity in multilingual societies.
