Nigeria’s healthcare sector faces a chronic deficit in its doctor-to-patient ratio, estimated at nearly 1,000% below the World Health Organisation (WHO) recommendation. This shortage, driven by infrastructural decay and the persistent brain drain of health professionals, poses profound implications for attaining Sustainable Development Goal 3 on good health and well-being. While government policies, such as the 2024 National Policy on Health Workforce Migration, attempt to address the challenge, they largely overlook technology’s transformative role. This article examines how digital health tools, particularly telemedicine, artificial intelligence (AI), electronic health records (EHR), and medical robotics, can serve as innovative solutions to bridge Nigeria’s ratio gap. The article adopts a purely doctrinal approach, consulting statutes, journal articles, newspaper articles, books, etc. It finds that technology plays an immense role in better healthcare delivery, but several issues bordering on financing, data protection, patient privacy, medical liability, and institutional oversight pose a concern. It concludes that if embedded within robust legal safeguards, technology offers a sustainable pathway to enhancing healthcare delivery, protecting patients’ rights, and accelerating Nigeria’s Progress toward SDG 3. Drawing on comparative frameworks from other jurisdictions and international best practices, the article recommends that Nigeria establish a comprehensive legal and institutional framework for digital health, accompanied by deliberate policy and infrastructural reforms.
