Google Releases Kotlin FHIR: Accelerating Healthcare Data Processing Across Multiple Platforms

Kotlin FHIR: desarrollo sanitario multiplataforma con una sola base de código

October 1, 2025Google

Summary

Google has announced 'Kotlin FHIR,' an open-source library. This tool enables the development of applications based on the FHIR standard to run simultaneously across multiple platforms, including Android, iOS, and Web.

Details

Google's Kotlin FHIR significantly improves development efficiency for healthcare data exchange by utilizing the international standard FHIR (Fast Healthcare Interoperability Resources). A major challenge in many regions is developing and maintaining separate applications for various operating systems like Android and iOS. This library leverages Kotlin Multiplatform (KMP) to allow developers to build logic adaptable across platforms from a single codebase. It implements the FHIR data model directly, generating code based on official specifications (R4, R4B, R5, etc.) using a tool called KotlinPoet, ensuring data integrity. This allows development teams to provide data management solutions that work across various environments—for example, from hospital systems to mobile apps used by healthcare workers with iPhones—using one single logic base. This approach accelerates digital health initiatives, particularly in resource-limited areas, contributing to the realization of global interoperability based on FHIR.
