Why teams connect DuckDB and eClinicalWorks

Mirror eClinicalWorks's data into DuckDB so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like eClinicalWorks through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in DuckDB.

Stacksync mirrors Medications, Allergies, Immunizations, Documents from eClinicalWorks into Views, External files (Parquet/CSV/JSON), Attached databases, Database files in DuckDB and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into eClinicalWorks, so the tool and the database never disagree.

Common use cases

  • Feed appointment events to reminder and messaging platforms to reduce no-shows.
  • Keep provider directories consistent between eClinicalWorks and scheduling or marketing systems.
  • Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.

Automate eClinicalWorks from your codebase

Write to the synced tables in DuckDB and Stacksync propagates the change into eClinicalWorks, replacing custom integration code.

React to changes as they happen

Updates in eClinicalWorks arrive as row changes in DuckDB, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

What you can sync between DuckDB and eClinicalWorks

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

DuckDB objects eClinicalWorks objects
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Medications Prescription and medication-list data within the patient record.
Schemas Namespaces within a database used to organize tables in sync outputs. Allergies Allergy and intolerance entries in the clinical record.
Tables Columnar tables created via SQL; the destination for materialized sync data. Immunizations Vaccination history exposed for registries and patient apps.
Views SQL views used to shape or filter data for downstream consumers. Documents Clinical notes and attachments referenced from the chart.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Diagnostic reports Structured result reports grouping observations for a study or panel.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Patients Demographic records exposed via FHIR Patient resources and HL7 ADT feeds; the anchor for all clinical syncs.

How the DuckDB and eClinicalWorks connectors work

DuckDB

Integration surface
In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default
Authentication
None built in; access control is file-system level (MotherDuck adds token auth for its hosted service)
Change detection
Polling or full re-reads; no change feed or transaction log API
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by local compute and I/O

eClinicalWorks

Integration surface
FHIR R4 REST API plus HL7 v2 interfaces (ADT, SIU, ORU) through an interface engine
Authentication
OAuth 2.0 / SMART on FHIR for the FHIR API; site-configured credentials for HL7 interface connections
Change detection
HL7 interface feeds push event messages as they occur; the FHIR API is polled
Capabilities
