Governed Data Foundation for a Regional Health System
Unified clinical and operational data under a single governance model ahead of a system-wide analytics rollout.
The Problem
A regional health network had clinical data spread across multiple EHR instances and operational systems with inconsistent access controls, blocking a planned analytics initiative until governance could be proven to auditors.
The Architecture
We implemented Unity Catalog as the single governance layer across all Databricks workspaces, standardizing access policies, column-level masking for PHI, and full lineage tracking from source to report — so any column's provenance can be traced instantly.
The Solution
Analytics and data science teams can now discover and request access to governed datasets through a single catalog, with automatic PHI masking applied based on role rather than manual review for each request.
Business Value
The health system passed its compliance audit with zero findings and cut new-analyst onboarding time by half.
