The problem

Slow data

FHIR server here, warehouse there, ETL pipelines in between.

Split governance

Each system has its own access controls, audit trails, and compliance.

Stalled AI

Models can't reach clean, trusted data at the point of need.

Before: two separate systems with ETL/CDC between FHIR server and warehouse

After: single Databricks Lakebase environment with FHIR and analytics unified

One dataset, every tool, no data movement

Aidbox runs natively on Databricks Lakebase, a serverless Postgres inside the Data Intelligence Platform.

FHIR data standardized at entry

No transformation after the fact.

Immediately available everywhere

Spark, ML, AI agents, BI dashboards.

Zero data movement

No ETL, no copy, no delay.

How it works

Three steps to a unified FHIR-native data platform on Databricks.

Step 1. Aggregate and standardize

Health Samurai's open-source converters (HL7v2, C-CDA, X12) transform legacy data into FHIR. A terminology server normalizes codes across vocabularies. MDM/MPI deduplicates patients into a single golden record. Quality is enforced at the point of entry, not after the fact.

Step 2. Store on Lakebase, access everywhere

Aidbox runs on Lakebase. Data replicates through Moonlink with zero ETL, so operational FHIR data flows into the analytical layer without pipelines, without transformation, without delay. Two access patterns from a single dataset: Databricks-native (Spark, SQL, ML, AI/BI) and standards-based (FHIR API, SMART on FHIR, SQL on FHIR ViewDefinitions).

Step 3. Govern once with Unity Catalog

The same access controls, audit trails, and policies apply across both the clinical application layer and the analytics layer. No governance gaps. No reconciliation. One policy framework for all data.

Full platform architecture

Data Sources → Health Samurai Ingestion → Aidbox on Lakebase → dual access (FHIR + Databricks) → Use Cases, with Unity Catalog spanning everything and Moonlink as the zero-ETL bridge.

What you can build

A FHIR-native foundation unlocks three high-value use cases, without the usual data plumbing.

EHR optimization and value-based care

Clinical and administrative decision support powered by Databricks AI, connected back to EHR workflows through SMART on FHIR and CDS Hooks.

Member engagement at scale

Build meaningful relationships with patients and members through standards-compliant infrastructure.

Compliance: built in, not bolted on

Build on FHIR and open standards, and CMS/ONC requirements are met by design.

Use cases

See what teams are already building, from clinical research to CMS compliance.

Aggregate data from multiple sources, validate it, and improve its quality on the way in. Everything is normalized to FHIR, so analytics runs on one clean dataset.

Data Platform reference architecture — multi-source ingest, validation and quality control, normalization to FHIR, and downstream analytics on top of the aggregated data on Databricks Lakebase.

Provider-facing applications aggregating data from EHRs, medical devices, and external sources for AI/ML analytics and CDS recommendations. Results are delivered back to EHRs in a standard way via SMART on FHIR apps and CDS Hooks.

CDS tools reference architecture — provider-facing apps aggregate data from EHRs, medical devices, and external sources, run AI/ML analytics, and deliver CDS results back to EHRs via SMART on FHIR apps and CDS Hooks.

Aggregate data from multiple sources, collect additional patient-reported data (FHIR SDC), and create a 360 patient view. Enables scheduling, consent management, and other patient engagement improvements.

Patient portals reference architecture — aggregate data from multiple sources, collect patient-reported data via FHIR SDC, and build a 360 patient view enabling scheduling, consent management, and engagement.

Patient Access API, Provider Directory API, Provider Access API, Prior Authorization API (CMS 9115, 0057, 0062, ONC g10, G9). FHIR data access and sharing, SMART on FHIR app store.

CMS / ONC compliance reference architecture — Payerbox as the CMS-0057-F layer on Databricks Lakebase. Data flows from payer internal systems through Payerbox to Patient Access APIs, healthcare providers, and other payers, with Lakebase feeding Databricks Lakehouse, Agent Bricks, and BI/AI.

Why this matters now

Three forces are reshaping how healthcare data platforms are built.

Regulatory deadlines are accelerating

CMS and ONC timelines won't wait for your ETL pipelines to catch up.

AI needs governed data

Models are moving from pilots to production, but only on trusted, standardized foundations.

Open standards, no lock-in

FHIR + Lakebase + Unity Catalog means you own the architecture.

Platform at a glance

Eight building blocks that make up a FHIR-native health data platform on Databricks.

Ingestion

HL7v2, C-CDA, X12 converters (open-source).

Terminology

FHIR-native server, cross-vocabulary normalization.

Patient matching

MDM/MPI: one golden record per patient.

FHIR server

Aidbox on Databricks Lakebase (serverless Postgres).

Zero ETL

Moonlink replication to the analytical layer.

Access patterns

FHIR API, SMART on FHIR, SQL on FHIR ViewDefinitions, Spark, SQL, ML.

Governance

Unity Catalog across clinical + analytics layers.

Standards

FHIR R4 / R5 / R6, HL7 Implementation Guides.

Already running Aidbox outside Lakebase?

You don't need Lakebase to start. Aidbox can stream FHIR data into a Databricks lakehouse today through the AidboxTopicDestination subscription — no custom ETL pipelines required.
