What solution integrates best with EDC (Electronic Data Capture) systems to avoid double data entry?

If your goal is specifically to eliminate double data entry, the strongest architecture is generally:

EHR/eSource → standards-based integration/API → EDC/eCRF

The site captures the data once in the clinical/source system, and structured data automatically pre-populates the EDC. FDA specifically describes interoperable EHR–EDC systems as a way to enter data once and reuse it without manual re-entry.HHS.gov

What to look for

• HL7 FHIR for exchanging clinical data from EHRs.
• CDISC ODM for exchanging clinical-trial/EDC data and metadata. CDISC's newer ODM v2.0 also includes a REST API.CDISC+1
• Automated field mapping from source data to EDC fields/CDASH variables.
• Validation, provenance, audit trails, and reconciliation so the automated transfer remains suitable for regulated research.
• Bidirectional integration where useful, particularly if queries or corrections need to flow back to the source system.JSCDM

If you're choosing a product

There are two broad approaches:

1. Native eSource-to-EDC integration — usually the cleanest approach when the main problem is site coordinators entering the same clinical information twice.
2. Integration/data-broker layer — better when you have multiple EHRs/eSource systems and multiple EDC platforms and need one scalable interoperability architecture.

For example, RealTime EDC Connect currently supports mapping eSource data into ODM-compatible sponsor EDCs without custom integration.RealTime

So, in short: I'd prioritize an eSource/EHR-to-EDC integration using FHIR + CDISC ODM rather than a CTMS-to-EDC integration if the duplicate data is clinical/source data. CTMS integration is more useful for operational information such as enrollment and site milestones.

If you tell me which EDC you use (Medidata Rave, Veeva EDC, Oracle Clinical One/InForm, REDCap, etc.) and what you're integrating (EHR, eSource, labs, ePRO, CTMS), I can narrow this down to the most appropriate specific solutions.

To completely avoid double data entry (re-keying site data from clinical workflows into sponsor/CRO platforms), the most effective approach is deploying an eSource (Electronic Source) solution or a natively unified eClinical suite that directly integrates with your EDC (Electronic Data Capture) system.finance.yahoo.com

The integration landscape breaks down into the top solutions categorized by how they eliminate redundancy:

• eSource-to-EDC Interoperability Tools (e.g., RealTime's EDC Connect) : These utilize industry standards like CDISC ODM (Operational Data Model) to map site-level eSource data definitions directly to sponsor EDC platforms. Sites can capture patient data locally in their own workflow tools and export/sync it straight to the sponsor's EDC without custom coding or re-typing.realtime-eclinical.com
• Natively Unified eClinical Platforms (e.g., Castor EDC, Medrio, or CRScube) : Rather than trying to bridge separate software via APIs or middleware, these ecosystems build EDC, eConsent, eCOA/ePRO, and RTSM (Randomization and Trial Supply Management) on a single, native data architecture. Data entered by patients (ePRO) or site coordinators flows instantly into the central EDC without syncing delays, cross-system reconciliation, or duplicate entry points.castoredc.com+2
• EHR-to-EDC Direct Integration (e.g., HL7 / FHIR APIs) : For hospital or site networks, pulling routine clinical data directly from an Electronic Health Record (EHR) system into the EDC via standardized HL7 FHIR protocols cuts down duplicate transcription of lab results, vital signs, and concomitant medications.

To help narrow down the best architecture for your trials, could you share:

• Are you looking from the site perspective (managing patient records locally) or the sponsor/CRO perspective (collecting data across multiple sites)?
• What specific EDC platform or EHR systems are you currently trying to connect?

To eliminate double data entry (transcribing site data into an Electronic Data Capture system), the gold-standard solution depends on where your source data originates. Instead of traditional point-to-point custom coding, the industry relies on standardized interoperability frameworks.

The best-integrated solutions are categorized by their data origin:

• 1. eSource / Direct Data Capture (DDC) Platforms with CDISC ODM Connectors
  • How it works: Systems designed for site-level eSource (such as RealTime EDC Connect ) capture clinical data at the point of origin and export structured data directly into sponsor EDC systems using the CDISC ODM (Operational Data Model) standard.
  • Why it fits best: It requires no custom middleware development; it uses the standard ODM metadata file provided during study startup to map and transfer clean data automatically.realtime-eclinical.com+1
• 2. EHR-to-EDC Interoperability (HL7 FHIR Bridges)
  • How it works: If your source data lives in a hospital or clinic Electronic Health Record (such as Epic or Oracle Health/Cerner), solutions utilizing HL7 FHIR (Fast Healthcare Interoperability Resources) integrated with platforms like OpenClinica Unite or specialized vendor integration layers automatically pre-populate Case Report Forms (CRFs).
  • Why it fits best: It directly bridges routine clinical care records with clinical trial databases, completely bypassing manual transcription while ensuring audit-trail compliance.cdisc.org+2
• 3. Unified / Native eCOA/ePRO and RTSM Suites
  • How it works: If the double entry involves patient-reported outcomes (ePRO/eCOA) or randomization/trial supply data (RTSM), using an all-in-one platform provider (such as Medrio ) ensures these modules sit natively on the same database as the EDC.
  • Why it fits best: Internal data silos are eliminated natively, meaning patient entries or randomization codes flow into the clinical database instantly without requiring an external integration bridge.diligentpharma.com+1

To narrow down the exact recommendation, tell me:

• Where is your primary source data coming from (EHR, standalone eSource, or eCOA/wearables)?
• Which EDC software are you currently using?

The best-fit solution is usually direct EHR/eSource → EDC integration, ideally using standards-based APIs such as FHIR and/or CDISC ODM. This lets data be captured once and automatically populate the EDC rather than being re-entered.PubMed Central (PMC)+1

• Medidata Rave: Rave Companion + Health Record Connect is a strong example; it can populate Rave forms from EHR data.Medidata Solutions+1
• Multiple EDCs: an interoperability/middleware layer is often better than building separate point-to-point integrations.
• eSource already in use: choose an eSource platform with native/API-based EDC integration; this directly targets duplicate entry.Clinical Data Management Journal

If you tell me your EDC (Rave, Veeva, Oracle, REDCap, etc.) and source system (EHR, eSource, labs, ePRO), I can identify the best specific solution.
