The Unified Health Interface (UHI) of the Ayushman Bharat Digital Mission (ABDM) is an open network with common protocols, so that a patient and a provider need not be on the same app to interact.
- A request from any UHI enabled app goes through the ABDM Gateway, run by the National Health Authority (NHA), to registered providers, and discovery, booking and fulfilment use one common language.
- It uses the Ayushman Bharat Health Account (ABHA) to identify patients, the Healthcare Professionals and Health Facility Registries to verify providers, and the Health Information Exchange for consent based data sharing.
- Its four principles are interoperability, fair discoverability, verification and open protocols.
- The Drug Registry becomes ABDM's fourth core registry, using codes from the Systematized Nomenclature of Medicine Clinical Terms so the same medicine is not entered under different names across systems.
- Full hospital management systems are too costly for small clinics, which slows ABDM adoption.
ABDM's four registries
| Registry | What it identifies |
|---|---|
| Ayushman Bharat Health Account (ABHA) | Individuals |
| Healthcare Professional Registry | Doctors and other health professionals |
| Health Facility Registry | Hospitals, clinics and other facilities |
| Drug Registry | Medicines, by brand, generic, substance and manufacturer |
