eClinicalWorks FHIR $export Sprint — Production-Ready in 6 Weeks
The $export operation in eClinicalWorks FHIR is the bulk-data API that lets you pull patient cohorts as NDJSON files using SMART Backend Authorization. It is required for ONC (g)(10) certification and for population-health and quality-reporting workflows. Most eCW deployments hit two failure modes: SMART Backend Auth setup, and timeout/file-size limits on large cohorts. We resolve both — typically in a 4–6 week fixed-price sprint starting at $13,500.

Why Teams Do This Sprint
ONC (g)(10) certification
$export is required for ONC's g10 single-patient and multiple-patient API criteria. Without it, you can't certify your application for ONC submission.
Population health workflows
Quality reporting (HEDIS, MIPS) and population-health cohort building need bulk patient data, not one-by-one resource fetches. $export is the API for that scale.
SMART Backend Authorization is non-trivial
JWT signing, JWKS publishing, asymmetric client_credentials flow — the spec is well-defined but the implementation is where teams stall. We've shipped it across multiple eCW deployments.
Timeout and chunking discipline
Naive $export implementations time out at 30 minutes on large cohorts. Production-ready exports use _since, _typeFilter, and chunked retrieval.
Cross-EHR portability
The same code patterns work for Epic, Cerner, athenahealth $export. Once you're set up for eCW, expanding to other EHRs is incremental.
What We Deliver
Concrete deliverables. Code in your Git repo at the end.
Common Problems We Fix
If any of these match your situation, the sprint resolves them.
401 Unauthorized on the $export POST despite valid client credentials
Root cause: JWT signing or JWKS publishing issue. Common: signing with the wrong key, missing kid in the JWT header, or JWKS endpoint not publicly reachable.
$export returns 202 Accepted but Content-Location polling never completes
Root cause: eCW timeout or task-queue backlog. Solution: chunked exports with smaller cohorts and proper polling cadence (15–60 seconds, exponential backoff up to 5 minutes).
NDJSON downloads partially complete then fail mid-stream
Root cause: Connection-pooling, retry handling, or transient network issues. Solution: streaming downloader with byte-range resume support and exponential retry.
Large cohort exports timeout at 30 minutes
Root cause: Single-shot export of full patient population. Solution: chunked exports with _since and _typeFilter parameters to break into incremental retrievals.
Returned resources missing required FHIR R4 elements
Root cause: eCW configuration of profile-conformance levels. Solution: configure US Core profile conformance in eCW admin and validate output against US Core profiles before ETL.
Group endpoint returns 404 even though group is configured
Root cause: eCW Group resource ID format mismatch (some deployments use logical IDs, others use technical IDs). Solution: verify Group identifier system + value via FHIR search before $export.
