MDMbox

MDMbox is a master data management service for healthcare organizations. It identifies duplicate records across FHIR resources using probabilistic matching and provides tools to merge and manage them.

Core capabilities

Probabilistic matching. Configurable Fellegi-Sunter models compare records across multiple dimensions (name, date of birth, address, phone) and produce a match score. Handles typos, incomplete data, and transpositions.

Merging. FHIR R5-aligned $merge operation with a client-driven approach — the client builds the merge plan as a FHIR transaction Bundle, giving full control over which fields survive and how related resources are reassigned. Full audit trail and preview mode.

Bulk matching. Find all duplicate pairs across millions of records in parallel. Download results as CSV.

Admin UI. Server-rendered interface for managing matching models and running bulk match jobs.

FHIR R4 to R6. Matching, merging, and referencing operations work with any FHIR resource type — Patient, Practitioner, Organization, or any other. Configure a matching model for the resource type you need.

Deployment modes

MDMbox runs as a single Docker container with an embedded FHIR engine. It connects to a PostgreSQL database.

Standalone — MDMbox manages its own database. Deploy MDMbox and PostgreSQL, and you are ready to go.

Shared with Aidbox — MDMbox connects to an existing Aidbox database. Both services share the same PostgreSQL instance and FHIR data. Pass the same BOX_* environment variables to both services.
