Interoperable Health Terminology API for India

Harsh Bhade^1*

Abstract

Healthcare information systems often face challenges related to fragmented Electronic Health Records (EHRs), inconsistent medical terminology, and poor semantic interoperability. These issues reduce the efficiency of healthcare communication, reporting, and clinical decision-making. This study presents the design and development of an Interoperable Health Terminology API for India that integrates ICD-11 and HL7 FHIR standards into a unified API-based framework. The proposed system provides terminology search, translation, autocomplete, and value set retrieval services through REST APIs. The framework is developed using Python, Flask, React, SQLite, and Docker technologies. It also supports ABHA-linked FHIR records with role-based access control and consent-aware workflows. By centralizing terminology management, the system improves semantic consistency, healthcare data exchange, and interoperability between Electronic Health Record systems. The proposed solution can support healthcare providers, researchers, hospitals, and digital health platforms in building standardized and scalable healthcare applications.
