Use Cases

Why integrate with eClinicalWorks

Common scenarios for SaaS companies building eClinicalWorks integrations for their customers.

Launch an AI pre-visit co-pilot for ambulatory clinics

Offer eClinicalWorks customers an AI assistant that reads tomorrow's schedule and synthesizes patient history into a one-page brief. Truto handles FHIR auth and pagination so you can focus on the summarization logic, not EHR plumbing.

Power chronic care management and population health programs

Help practices identify Medicare CCM-eligible patients by continuously syncing conditions, care plans, and coverage data from eCW. This unlocks net-new revenue for your clinic customers and justifies premium pricing tiers.

Build a patient reactivation CRM on top of EHR data

Trigger SMS and email outreach based on real clinical signals — uncompleted procedures, missed follow-ups, or overdue screenings — pulled directly from eCW. Your SaaS becomes the growth engine for ambulatory practices.

Enable referral and chart extraction workflows

Pull structured problem lists, medications, and C-CDA documents from eCW to power referral platforms, prior auth tools, or AI chart summarization. Truto exposes DocumentReference and Binary endpoints so you can retrieve raw clinical notes without wrestling with FHIR semantics.

Deliver remote patient monitoring with structured EHR writeback context

RPM and device SaaS vendors can pull observations and diagnostic reports from eCW to track vitals and chronic condition trends in context. Give clinicians a longitudinal view that blends in-clinic labs with at-home device data.

What You Can Build

Ship these features with Truto + eClinicalWorks

Concrete product features your team can ship faster by leveraging Truto’s eClinicalWorks integration instead of building from scratch.

Automated pre-visit chart summarization

Pull upcoming encounters, then fan out to conditions, medication requests, allergies, and diagnostic reports for each patient to generate a physician-ready brief.

Chronic condition registry sync

Continuously list conditions and filter by chronic categories, cross-referenced with active care plans and coverage records to flag CCM-eligible patients.

Clinical document and C-CDA ingestion pipeline

Search document references by patient or type, then fetch the raw base64 payload via the Binary endpoint for downstream parsing or AI summarization.

Provider and location directory sync

Mirror the clinic's practitioner roster, practitioner roles, organizations, and locations to route tasks, assign messages, and map schedules in your product.

Longitudinal vitals and labs timeline

Aggregate observations and diagnostic reports per patient to render a time-series view of vitals, A1C trends, lipid panels, and other chronic condition markers.

Procedure-based patient reactivation campaigns

List procedures and encounters to detect patients with ordered-but-uncompleted procedures and no upcoming visits, then trigger drip outreach from your CRM.

Why Truto

Why use Truto’s MCP server for eClinicalWorks

Other MCP servers give you a static tool list for one app. Truto gives you a managed, multi-tenant MCP infrastructure across 850+ integrations.

Auto-generated, always up to date

Tools are dynamically generated from curated documentation — not hand-coded. As integrations evolve, tools stay current without manual maintenance.

Fine-grained access control

Scope each MCP server to read-only, write-only, specific methods, or tagged tool groups. Expose only what your AI agent needs — nothing more.

Multi-tenant by design

Each MCP server is scoped to a single connected account with its own credentials. The URL itself is the auth token — no shared secrets, no credential leaking across tenants.

Works with every MCP client

Standard JSON-RPC 2.0 protocol. Paste the URL into Claude, ChatGPT, Cursor, or any MCP-compatible agent framework — tools are discovered automatically.

Built-in auth, rate limits, and error handling

Tool calls execute through Truto’s proxy layer with automatic OAuth refresh, rate-limit handling, and normalized error responses. No raw API plumbing in your agent.

Expiring and auditable servers

Create time-limited MCP servers for contractors or automated workflows. Optional dual-auth requires both the URL and a Truto API token for high-security environments.

How It Works

From zero to integrated

Go live with eClinicalWorks in under an hour. No boilerplate, no maintenance burden.

Link your customer’s eClinicalWorks account

Use Truto’s frontend SDK to connect your customer’s eClinicalWorks account. We handle all OAuth and API key flows — you don’t need to create the OAuth app.

We handle authentication

Don’t spend time refreshing access tokens or figuring out secure storage. We handle it and inject credentials into every API request.

Call our API, we call eClinicalWorks

Truto’s Proxy API is a 1-to-1 mapping of the eClinicalWorks API. You call us, we call eClinicalWorks, and pass the response back in the same cycle.

Unified response format

Every response follows a single format across all integrations. We translate eClinicalWorks’s pagination into unified cursor-based pagination. Data is always in the result attribute.

FAQs

Common questions about eClinicalWorks on Truto

Authentication, rate limits, data freshness, and everything else you need to know before you integrate.

What eClinicalWorks API does Truto connect to?

Truto connects to the eClinicalWorks FHIR R4 API, which is the standard interface eCW exposes for third-party clinical data access. All available resources — Patient, Encounter, Condition, Observation, DocumentReference, Binary, and more — follow FHIR R4 semantics.

How does authentication work for end users connecting their eCW account?

eClinicalWorks uses SMART-on-FHIR OAuth 2.0 for authorization. Truto handles the full OAuth handshake, token refresh, and tenant-specific endpoint routing, so your end users just complete a standard consent flow and your product receives a connected account.

What clinical data can I read from eClinicalWorks today?

Truto exposes read and list access to Patients, Practitioners, PractitionerRoles, Organizations, Locations, RelatedPersons, AllergyIntolerances, Conditions, Encounters, Immunizations, Medications, MedicationRequests, MedicationAdministrations, Observations, Procedures, DiagnosticReports, DocumentReferences, Binaries, CarePlans, CareTeams, Goals, Devices, Coverages, and Provenance records.

Can I write data back into eClinicalWorks?

The current eCW integration is read-oriented, which reflects what eClinicalWorks' FHIR API primarily supports for third-party apps. If you need specific write operations for your workflow, reach out and Truto can scope writeback endpoints on request.

How do I retrieve the actual content of a clinical note or C-CDA document?

List document references to find the note you need, then call the Binary endpoint with the referenced ID to retrieve the base64-encoded payload. This is the standard FHIR pattern for extracting clinical note content and C-CDA bundles from eCW.

How fresh is the data I get back from eClinicalWorks?

Truto reads directly from the eCW FHIR API in real time, so every list or get call returns the latest state at the moment of the request. For continuous sync use cases, you can schedule polling jobs on the resources you care about using Truto's sync primitives.
