Bringing AI to India’s digital health infrastructure

India’s National Health Authority (NHA) took a major step forward in strengthening the country’s digital public infrastructure today, launching the new Aarogya Setu 2.0 app. After playing an important role in India’s response to the global COVID-19 pandemic, the app has evolved into a unified platform that securely aggregates personal health records and government digital health services.

We’re thrilled that this new application has leveraged Gemma 4, our most capable open models yet, and open Medical Data Toolkit.

Making sense of medical records

The NHA has utilized the Medical Data Toolkit and Gemma 4 as part of the new app to help process health records, which are often complex and unstructured, preventing patients and doctors from easily accessing and understanding health information.

The combined strength of Google’s open Medical Data Toolkit and Gemma 4, built into the Aarogya Setu 2.0 app, helps address this challenge. The toolkit and Gemma 4 models intelligently identify the specific type of health record, and extract critical information - like lab test names, methods and results - from text and images. The Medical Data Toolkit then maps and structures the information into standard Fast Healthcare Interoperability Resources (FHIR) data, a universal format that supports different healthcare systems to seamlessly share health records digitally. Overall, this supports NHA’s efforts to enable smoother transitions of health information when patients move across hospitals and healthcare providers.

The Medical Data Toolkit uses a set of defined rules to structure the extracted information. All health records and health information are controlled by the user within the Aarogya Setu 2.0 app.

Open-sourcing AI for India’s health ecosystem

We want to bring the benefits of this technology to the broader digital health ecosystem. The Medical Data Toolkit is now open sourced to developers and health organizations at no cost. It can support development of health applications that require digitization and standardization of legacy health records, while supporting compliance with India’s interoperability standards under Ayushman Bharat Digital Mission (ABDM). The initial release of this toolkit is optimized for supporting some of the most common types of health records, such as laboratory reports and observations.

This release also builds on our previous measures to open source a wrapper that helped Indian developers integrate their health apps with the ABDM architecture.

We are proud to deepen our commitment to India’s inspiring AI ambition and the digital health developer community.
