Executive Summary & Architectural Takeaways

A comprehensive architectural guide to building ABDM-aligned healthcare information systems, LOINC/SNOMED diagnostic interfaces, and fast cloud PACS DICOM viewers.

The ABDM Digital Health Mandate #



Under India's Ayushman Bharat Digital Mission (ABDM), healthcare institutions must eliminate manual paper prescriptions and implement standardized, interoperable electronic health records.

Divanex builds end-to-end ABDM M1, M2, and M3 aligned hospital platforms enabling: - Instant patient registration using **ABHA QR code scanning**. - Cryptographically signed electronic health records (EHR) pushed to national health lockers. - Consent-driven clinical data exchange between hospitals, clinics, and diagnostic labs.

HL7 FHIR v4 Clinical Data Modeling #



All patient summaries, lab investigations, and discharge notes are represented as standard **HL7 FHIR v4 JSON resources** tagged with LOINC diagnostic test codes and SNOMED-CT clinical terminology.

Zero-Footprint Browser DICOM Imaging #



By converting 500MB+ CT and MRI imaging files into edge-tiled WebP fragments, radiologists and consulting doctors can review 4K scans on tablet browsers with smooth pan-and-zoom in under 150ms.
