💡 Why Fabric for Healthcare¶

Unified platform for diverse clinical data. Healthcare organizations typically operate dozens of siloed systems — EHR, lab, pharmacy, claims, devices. Fabric's OneLake eliminates data copies by providing a single storage layer that Lakehouse, Warehouse, and Eventhouse all read from, reducing data sprawl and governance risk.

Built-in compliance primitives. Row-level security, column-level security, sensitivity labels, customer-managed keys, and SQL audit logs map directly to HIPAA technical safeguards — without bolting on third-party tools.

Real-time clinical alerting without custom code. Medical device telemetry flows through Eventstreams into Eventhouse, where Data Activator can trigger alerts on abnormal vitals — no Kafka clusters or custom stream processing required.

Direct Lake for clinical dashboards. Clinicians and administrators need sub-second dashboard performance. Direct Lake reads Parquet files directly from OneLake into Power BI, eliminating import refresh windows and keeping PHI in a single governed location.

Predictive analytics at scale. AutoML model endpoints can score readmission risk, sepsis probability, or length-of-stay predictions on Gold-layer data without moving data to a separate ML platform.

🚀 Getting Started¶

1. Stand up the medallion architecture — Follow Tutorial 01: Bronze Ingestion and Medallion Deep Dive to create lh_bronze, lh_silver, lh_gold Lakehouses.
2. Map FHIR resources to Silver schemas — Normalize FHIR R4 Bundles (Patient, Encounter, Observation, Condition) into Silver Delta tables with schema enforcement.
3. Apply security controls — Configure OneLake Security RLS/CLS, enable Customer-Managed Keys, and turn on SQL Audit Logs.
4. Stream device telemetry — Set up Eventstreams from IoT Hub to Eventhouse for real-time vitals monitoring.
5. Build Direct Lake reports — Create a semantic model over Gold tables and connect Direct Lake to Power BI for Patient 360 dashboards.
6. Deploy predictive models — Use AutoML to train and deploy a readmission risk model on the Gold layer.
