Building a FHIR-Native Health Data Platform to Overcome Data Silos
Building a FHIR-native health data platform on Databricks Lakebase
Summary
Health Samurai and Databricks provide a unified foundation by standardizing diverse clinical data (e.g., HL7v2, C-CDA) into FHIR. This enables access to trusted data for all tools, including AI/ML, without requiring complex ETL processes, accelerating digital transformation in healthcare.

This article addresses the challenge of fragmented and siloed healthcare data by proposing an integrated solution based on FHIR standards. Traditional approaches required separate FHIR servers for interoperability and data warehouses for analytics, leading to data duplication and bottlenecks. Health Samurai collects and standardizes legacy formats like HL7v2, C-CDA, and X12, creating a single 'golden record' using terminology systems such as LOINC and SNOMED CT into an FHIR-native foundation. By running this platform on Databricks, it achieves 'Zero ETL,' allowing reliable data to be accessed directly by Spark analytics and AI models without movement. This is particularly relevant for Japanese healthcare institutions needing to integrate data from EHRs and legacy systems while enabling advanced analysis.
