AI to Bridge Specialist Gaps in Underserved Regions: Ex-WHO Official

The persistent shortage of medical specialists in the Global South has long been a primary barrier to achieving universal health coverage. At the India AI Impact Summit 2026, Soumya Swaminathan, the former Deputy Director-General of the World Health Organisation, articulated a vision where artificial intelligence serves as the primary bridge for this diagnostic divide. In regions across India and Africa, where the ratio of radiologists, pathologists, and psychiatrists to the general population remains critically low, AI-driven diagnostic tools are no longer viewed as experimental luxuries but as essential infrastructure for public health.

The most immediate and profound impact of AI in these resource-constrained environments lies in image and pattern recognition. Swaminathan pointed to the interpretation of X-rays and pathology slides as 'low-hanging fruit' for AI integration. By automating the initial screening of diagnostic imagery, AI can filter out normal results and flag anomalies for the few available human specialists to review. This triage capability effectively acts as a force multiplier, allowing a single radiologist to oversee a significantly larger patient volume without a proportional increase in burnout or diagnostic error. However, the efficacy of these systems is entirely dependent on the quality of the training data. Swaminathan emphasized that for AI to be effective in diverse populations, algorithms must be trained on high-quality, representative datasets that reflect the specific demographic and pathological nuances of the regions where they are deployed.

At the India AI Impact Summit 2026, Soumya Swaminathan, the former Deputy Director-General of the World Health Organisation, articulated a vision where artificial intelligence serves as the primary bridge for this diagnostic divide.

Perhaps the most significant takeaway from Swaminathan’s address is the call for a fundamental shift in how AI healthcare products are regulated. She argued that the current 'move fast and break things' ethos of the technology sector is incompatible with patient safety. Instead, she proposed that AI solutions should be subject to the same rigorous clinical trial standards as new pharmaceuticals or vaccines. This 'clinical-grade' approach to AI development would require developers to prove not just technical accuracy, but clinical efficacy and safety in real-world settings before scaling. By integrating AI into a formal regulatory pathway, governments can ensure that the deployment of these technologies does not inadvertently widen health disparities through algorithmic bias or technical failure.

The broader market implications of this shift are substantial. As India hosts the first global AI summit in the Global South, it signals a move toward localized innovation. Rather than relying on AI models developed in Western clinical environments, there is a growing push for 'sovereign AI'—tools built by and for the populations they serve. This trend is likely to attract significant investment into Health IT infrastructure across emerging markets, as companies like the Tata Group and global players like Meta and OpenAI look to tailor their offerings to the unique needs of the Indian and African healthcare sectors. The focus on regulatory compliance and clinical validation will likely favor established health-tech firms and research institutions over smaller, less-regulated startups.

Looking forward, the success of AI in transforming healthcare in specialist-scarce regions will depend on the successful convergence of three factors: high-quality local data, robust regulatory frameworks, and the seamless integration of AI into existing primary care workflows. If these hurdles are cleared, AI could decentralize specialist-level care, moving it from tertiary urban hospitals to rural clinics. This would not only improve patient outcomes but also significantly reduce the economic burden of late-stage diagnoses. The industry should watch for the emergence of new regulatory guidelines from the Indian government following this summit, as they may set a precedent for AI governance across other developing economies.
