Consent-Based Health Record Exchange, Done Right

The real power of ABDM is interoperability — a patient's records flowing securely between every hospital, lab, and clinic they visit. That exchange runs on two roles: the Health Information Provider (HIP), which shares records it creates, and the Health Information User (HIU), which fetches records with patient consent. Medi4u builds both capabilities into your existing software and gets them NHA certified (M2 & M3).

Frequently Asked Questions

What is a HIP (Health Information Provider)?
A HIP is any facility that generates health data — hospitals, clinics, labs, pharmacies — and shares it on the ABDM network with patient consent. As a HIP, your software links care contexts to the patient’s ABHA and responds to consented data requests. Full explainer: HIP & HIU Explained.
What is a HIU (Health Information User)?
A HIU requests and views patient records from other providers — for example, a hospital fetching a patient’s previous lab reports before surgery. All access is consent-based through the ABDM consent manager (HIE-CM).
What is care context linking?
Every visit, prescription, or report is a "care context" linked to the patient’s ABHA. Linking care contexts is the core HIP responsibility — we automate it inside your OPD/IPD workflow so records link without extra staff effort.
How does consent management work in ABDM?
Patients grant, deny, or revoke access to their records via consent artefacts managed by the HIE-CM. Our integration handles consent notifications, artefact validation, data encryption, and expiry automatically. Read: ABHA Consent Management Guide.
Do I need HIP before HIU?
Yes, NHA certification is sequential: Milestone 1 (ABHA), then Milestone 2 (HIP), then Milestone 3 (HIU). Medi4u takes you through all three — see our complete ABDM integration service.
