Why teams connect Citus and eClinicalWorks

Mirror eClinicalWorks's data into Citus 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 Citus.

Stacksync mirrors Documents, Diagnostic reports, Patients, Appointments from eClinicalWorks into Views, Sequences, Distributed tables, Reference tables in Citus 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

  • Push referral or intake data captured in external forms into the EHR via HL7 interfaces.
  • Sync patient demographics and appointments into a CRM so patient outreach and intake teams work from current data.
  • Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
  • Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.

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.

Read eClinicalWorks with a query

Records from eClinicalWorks are ordinary rows in Citus; join them, index them, and use them in application logic without touching the vendor API.

Automate eClinicalWorks from your codebase

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

What you can sync between Citus 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.

Citus objects eClinicalWorks objects
Sequences Key generators that matter when external writes must not collide with application inserts. Observations Labs and vitals, delivered via FHIR resources or HL7 ORU result messages.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Medications Prescription and medication-list data within the patient record.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Allergies Allergy and intolerance entries in the clinical record.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Immunizations Vaccination history exposed for registries and patient apps.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Documents Clinical notes and attachments referenced from the chart.
Views Curated projections over distributed data, often used as read-only sync sources. Diagnostic reports Structured result reports grouping observations for a study or panel.

How the Citus and eClinicalWorks connectors work

Citus

Integration surface
PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
Authentication
Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
Change detection
PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
Capabilities
read · write · CDC

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
read · write
Rate limits
Subject to the platform's API rate limits and interface throughput agreements
