How We Built ABDM Integration Across a Multi-Module HIMS Suite

Every HIMS and EMR vendor selling into Indian hospitals is getting the same question from procurement teams right now: "Are you ABDM-integrated?" Nirmitee.io was the engineering partner that built and certified that integration for Pace Softronix — across all three ABDM certification milestones.

The Challenge

ABDM readiness has moved from a compliance checkbox to a shortlist requirement. Hospitals evaluating a HIMS or EMR vendor now ask "are you ABDM-integrated?" before they ask almost anything else.

For a single-product startup, that's one integration. For Pace Softronix, it's five. Pace's hospital and clinic customers run HIS, lab (Patho Expert), pharmacy (Pace RX), radiology (Radio Relief), and blood bank management as connected modules — and ABDM doesn't let a vendor certify one module at a time and call it done. Every module needs to resolve back to a single patient identity, register its own care contexts, and route through one consent layer.

On top of that, the certification path itself is sequential and technical:

• M1 requires a working identity layer — ABHA creation, verification, and Health Facility Registry (HFR) registration.
• M2 requires the system to serve FHIR R4 records on consent, encrypted with Fidelius, in NRCeS-conformant bundles.
• M3 requires the system to request, decrypt, and correctly display records coming in from other hospitals' HIP systems — each of which structures its FHIR bundles slightly differently.

Building this in-house meant either pulling core product engineers off Pace's roadmap for months, or hiring specialized ABDM expertise the team didn't have on staff — while hospitals already live on Pace's platform kept running day to day.

Why Pace Softronix Brought In Nirmitee as Its ABDM Integration Partner

• Healthcare-only. No ramp-up time spent explaining what a care context, an HFR ID, or a consent artefact is.
• Pattern already built. Nirmitee has open-sourced an ABDM Node.js SDK, so the integration patterns behind M1–M3 weren't being built from zero.
• Designed for Pace's multi-module reality. Instead of a separate integration per module, the ABDM layer was built once — a single bridge URL and a shared patient master index that every module (HIS, lab, pharmacy, radiology) resolves through.
• No rip-and-replace. The integration sits on top of Pace's existing HIMS/EMR architecture rather than forcing a rebuild.

What Nirmitee.io Built, Milestone by Milestone

M1 · Identity & Facility Registration — Can the system identify patients digitally?

• ABHA (Ayushman Bharat Health Account) creation, verification, and linking — Aadhaar OTP, mobile OTP, demographic methods, and QR scan-and-share
• Health Facility Registry (HFR) registration, giving Pace's hospital deployments their HIP identity inside the ABDM network
• Care-context linking so visits, admissions, lab orders, and pharmacy records all tie back to one ABHA

M2 · HIP — Serving Records — Can the system serve FHIR records when asked?

• Consent-artefact validation against ABDM's Consent Manager
• Conversion of records from each Pace module into FHIR R4 bundles conforming to NRCeS profiles
• Fidelius encryption and delivery to the requesting HIU through a single bridge URL

M3 · HIU — Consuming Records — Can the system request and display external records?

• Consent-request initiation and bridge-URL handling for incoming ABDM notifications
• Decryption and parsing of external FHIR bundles arriving from other hospitals' HIP systems
• Display of external patient records inside Pace's existing HIMS/EMR interface — no separate screen, no workflow disruption for clinicians already using the system

Results

• ABDM-certified end-to-end across M1, M2, and M3.
• Every module — HIS, lab, pharmacy, radiology, blood bank — runs on one ABDM identity and consent layer instead of five separate integrations.
• The integration was layered onto Pace's existing product architecture — no rebuild, no disruption to hospitals already live on the platform.

For context: hospital software vendors layering ABDM onto an existing HIS typically see a 4–6 month path from sandbox to production, versus 6–9 months for a greenfield build — per Nirmitee.io's ABDM certification guide. Actual timelines vary by module count and existing architecture.

“Nirmitee.io provided prompt and reliable consulting support throughout our ABDM implementation journey. Their team successfully guided us through ABDM Milestones M1, M2, and M3, demonstrating strong technical expertise and a clear understanding of the National Health Authority guidelines.

Their valuable assistance and hands-on support helped our team navigate the integration process efficiently and successfully.”
